How to defrost the PND tube underground. How to defrost a plastic tube: emergency help. To prevent such phenomena, follows

Russia is in the harsh climatic region, so in winter and early periods there is a risk of defrosting the water supply and sewage system. This is especially true for owners of private houses, because Often systems are laid without carrying out the necessary calculations and measures for insulation and protection against freezing. In this article, let's talk about how to protect the pipes from the freezing and what to do if it did not work to prevent the problem.

If the temperature outside the window dropped to zero, that is, before the temperature of the freezing of water, this does not mean that the water supply will freeze. Not everyone knows, but in winter, water in the pipe freezes at temperatures -7 degrees. Water pipes are bursting at freezing, because When moving from a liquid state into solid, the volume of water increases. This happens not often, but it happens, especially in metal systems that are not able to stretch.

To prevent the freezing of water in pipes and protect them from damage, it is necessary to take care of the heating system in advance or a set of activities on the thermal insulation of the pipeline.

Some measures to protect the pipeline in the winter should be carried out at the stage of laying communications during the construction of the house. What needs to be done to reliably protect pipes from cold during styling process:

1. Pour the plumbing below the level of ground freezing. In SNiP 2.02.01-83, you can find information on the depth of freezing for a particular region and the type of soil.
2. Use for underground polyethylene or polypropylene water supply.
3. . For convenience, insulation are used from a foil polystyolster in the form of tubes, or any other available insulation or insulation methods.
4. Mount the electrical heating system. It is installed directly on the water pipe under the heat insulation layer. The system is guaranteed to warn money or allows you to heat the water supply, if the heating is used cyclically and the freezing still happened.

Thermal insulation with the use of a heating cable is a reliable way to solve the problem of icing even in the strongest cold.

In private houses of temporary accommodation, such as country houses, the water supply is rarely laid underground and is used mainly in the summer.

To prevent the design of the design located above the ground, in winter, it is necessary to completely drain the water after each use. The second option, as you can not defrost the pipe on the street, it is to leave the crane a bit ajar, so that the water moves. Water in the source (well, well) has a temperature of about +5 degrees. Moving, she gives part of heat to heating, so the freezing of pipes in such a situation can occur only with a strong frost, from -15.

How to defrost outdoor pipeline

In the case when the open plumbing is not difficult to defrost the pipe, because It has access to it.

Tip: To start the work on the warming of water pipes immediately after the freezing is detected, otherwise, every hour the situation is only worsening, especially if insulation is used not qualitative or completely absent.

For heating the frozen plastic highways, heating cable will be required. It is extremely easy to use it, it is enough to wind the plumbing, and connect the cable to the power source. This option requires additional costs of purchasing a cable. You can cast plastic pipes with hot water, but this option is effective only with small areas of frozen, or with no strong frosts.

Heating pipes from metal can be carried out peripal open fire. A portable gas burner is suitable, a soldering lamp or a small diesel gun, designed to heat the unheated premises. You can combine heating with a burner with ice crushing method. With the help of the burner you can heat the entire metal system, with the exception of cranes. Cranes have rubber (plastic) valves, which, with a sharp increase in temperature, can be melted and the crane will have to be changed.

Important: It is forbidden to warm the frozen pipes from plastic by open fire, because They can melt or even light up.

To warm up the crane, it is not necessary to heat the burner, it is enough to wrap over a rag and pour steep boiling water. If after the first time the crane did not depart, the operation can be repeated.

For defrosting open, you can use a construction hairdryer. It is powerful enough, it warms well and is not able to melt the material.

Defrosting of hidden plastic pipes

Displays water in a plastic pipe hidden underground much more difficult because there is no access to it. Options of heating, which are used for open water pipes will not fit.

It is possible to quickly defrost the water supply pipe to it from the inside. For this there are several ways.

1. Chopping hot water.
2. Warming steam generator.
3. Warming up by an electrical apparatus for defrosting pipes.
4. Displays water pipes with a homemade boiler.

Depending on the situation, the presence of tools and other circumstances, various devices can be applied to each methods. For example, in order to cast hot water, you can apply a thin hose, which will pass inside the water pipeline, and you can simply pour hot water from the pear.

For defrosting PND pipes in the ground, you can use the cable heating system, but only if it was mounted at the plotting phase. If the elements of cable heating are not installed, then such a method is too time-consuming and not always possible.

Now consider the heating options that can be used if the PND pipe has frozen underground.

Warming steam generator

Based on the name, it can be understood that the steam generator is designed to produce steam. It sounds difficult, but in fact everything is much easier. But there are no steam generator. In everyday life, in the country, instead you can use a pressure cooker. Dispose the pipe pressure cooker is not more difficult than casting hot water. To carry out work:

• pressure cooker;
• the hose with a diameter is less than the plastic pipe of the water pipeline;
• mobile electrical or gas tile.

The process itself is similar to a hot water water supply, only steam is used instead of it. Water poured into the pressure cooker and heats up to a boil. One end of the hose is tightly connected to the valve for the release of excess steam in the pressure cooker cover, the other is dyed into the highway. Thus, steam from the pressure cooker enters the hose and further into the pipeline to the place of freezing. The temperature of the steam is higher than the temperature of the hot water, so the use of the pressure cooker gives a greater effect and allows you to warm up faster.

Another option to replace the steam generator is to use the Karher steam cleaner. Steam cleaner power is enough to cope with defrost.

Crushing ice

If the underground water supply is made of iron or copper, then a special device can be used for defrosting it - a device for defrosting pipes. What device model to use for a specific diameter of the pipe can be found by reading the instruction manual of the device. The most popular in Russia enjoy the Dragon devices and their analogues.

The essence of the method is that the power cable of the device is connected to the highway and the voltage is supplied to them, due to which the pipe walls are heated and the ice plumb is thawing. This method can be combined with crushing method.

Its essence lies in the appealing of the metal highway in order to cause ice peeling from the inner walls or its destruction. Rubbed slices of ice, under the pressure of water in the system can go out. Using this method, you need to take care of the unimpeded passage of ice pieces throughout the length of the water supply. This means that the exit crane, tees and other design elements that have a smaller diameter must be dismantled.

It seems simple, but in fact it turns out not always, because The device has restrictions on the distance of connecting the electrodes. If the electrode is not a problem from the output side of the tap pipe, then install the second, at a certain distance from the first is not always possible, due to the fact that the system is closed and the water frozen in the pipe under the ground. Sometimes such nuances do not make it possible to use the apparatus for heating the closed water supply system.

Defrosting with a boiler

At one end of the hard two-tier wire, there are several centimeters lived and cooled to the wire in such a way that the bare contacts do not hurt each other, and the distance between them did not exceed 1.5-2 cm. On the second end of the wire, the plug is installed for connecting to the household outlet . Further, the design is dyed inside the pipeline and connects to the network 220. The flow of the current, water between the contacts of the wire is heated, and the water supply is gradually thawing.

Important: The method is suitable for use in a closed system of plastic pipes, use in metal structures is strictly prohibited, because Pipe walls closed contacts.

Sparkling of hot water pipes

With a minor length of the frozen water supply, it is convenient to fill hot water from a bucket or rubber medical warmer, often called the circle of Escam. This is a simple way that requires minimum auxiliary devices. It is often used to independently eliminate the icing of pipes in the country. For heating, a piece of thin hose is needed with a length of no less than the length of the frozen highway and a funnel, for the convenience of filling the hose hot water.

The hose is inserted into the water pipe until it stops, that is, to the place of freezing. Next, hot water is poured into the hose. Hot water, passing through the hose, comes directly to the place of freezing and gradually melts the ice. As you confront, it is necessary to promote the hose inside the water pipeline and add hot water, because It will gradually leave and cool.

Elimination of ice cork in sewage

The sewage system, which is made with an improper bias, or from small diameter pipes and is laid without insulation, is at risk of defrosting. To warm the pipe is drained in a private house, in the event of an ice cork, it is possible by the same methods that are used for defrosting hidden water pipes.

Important: To eliminate ice, it is not enough to pour hot water into the toilet, because This is ineffective, it is necessary to organize a hot water supply directly to the ice plug place, which means you need to use the hose.

If the sewage system is quite long, then to deliver the hose to the place of freezing, it can be closed to a plumbing cable.

When defrosting there are several nuances.

1. The reason for the freezing may be a blockage, which reduced the bandwidth of the system. In this case, the defrost must be carried out together with cleaning, otherwise the problem is repeated.
2. In the sewer system can defrost a septack or a different drain pit. In such a case, the yield of water and feces is overlapped, the pipes are gradually filled and freezed. To eliminate the cause, you must first heat or clean the ice in the drain pit and only then begin to work on the warm-up drain works.

How to defrost metal pipes in the ground

Displays the pipes of the metal of metal, which are underground, can be the same methods that are used when you need to heat the PND tube in the ground. If there is access to the pipe every 10 meters, for example, wells are installed, it is effective to carry out warmth with the help of a pipe defrosting device.

The ice in the pipe under the ground begins to form at minus 5 degrees, which is closer to the spring, so in this period you need to be extremely attentive, especially if underground metal pipes are new and winter for the first time.

How can not be defrosting plastic pipes

Similar to metallic, plastic pipes are defrosting at temperatures from -5, but it is impossible to warm them all available methods. For example, it is forbidden to shive the frozen plastic pipes with open fire.

Plastic refers to combustible materials and can light up in a few minutes. Also for plastic communications does not apply the method of crushing and heating using the machine. The device will not work, because Polypropylene tube does not conduct electricity. At low temperatures, some types of plastic lose the properties of flexibility.

If you hit the frozen plastic system with a hammer or other impact tool, the walls may not withstand and burst. As a result, we will have to change part of the water pipeline. Metal-plastic pipes are bursting even easier, so crushing does not apply to them.

In conclusion, it should be noted that in order to avoid changing problems and water pipelines, it is not necessary to neglect the requirements of regulatory documents, such as SNIP SNiP 2.04.01-85 *. If the freezing failed to avoid, then after restoring the system's performance, it is necessary to analyze the reasons that can be eliminated during the war. Otherwise, the situation will be repeated. It is not always possible to get rid of the expansion of the water supply, because Integrity can be disturbed and the system will have to be changed in winter, or lay a temporary highway, which will require additional investments.

On the video, the original way of defrosting pipes hot water from the flow heater "Atmor":

In winter, quite often people face that water pipes with severe frosts can freeze. In this material, we will tell about how to defrost the pipe with water without damaging the communication and without staying for a long time without water.

In which cases may need to defrost pipes

In cases where water pipes were not insulated on time, with a sharp decrease in air temperature on the street water in them can freeze. However, even if such a trouble happened, you should not fall into a panic - everything can be corrected, including on our own.

Among the most common causes of the freezing of water pipes can be called incorrect laying of the highway without taking into account the depth of the primer of the soil or without insulation. Alternatively, it can occur with a water supply, which is used at a very low temperature or it takes too much water.

In order to defrost the pipes, you can use such equipment as a construction hairdryer (if there is no, the usual household suitable), the soldering lamp, an electric heater. We give several recommendations for the defrosting of frozen pipes.

When working with steel pipes, it is very simple to defrost. To do this, from the opposite ends of the pipes, the welding machine is connected, which will lead to the thawing of water inside the water supply system for 3-4 hours. The duration of the process depends on the length of the pipe. However, in recent times, plastic pipes can actively use plastic pipes that can withstand up to 10 atmospheres.

Although such products are not deformed during freezing, it is still impossible to draw out plastic pipes with the welding machine. You should also not use the iron bar for breaking the plug so as not to spoil the plumbing.

There are quite a lot of ways to defrost the pipe of the water supply pipe or sewage.

External heating

Of course, the need to break the frozen soil to get to the pipe is a significant disadvantage of this method. However, for those situations where the simplifying plot is small, this method has the right to exist.

When the trench is excavated, the type of pipeline material is installed. To work with polymeric products, you can use only the heating devices of the electric type, outstanding the temperature not more than 100-100. To reduce the heat loss and faster to warm the pipe, the place of work is covered with a layer of thermal insulation.

With metal pipes, the test tube pulling is faster, because it is possible to use an open fire source - firewood, gas burner, a soldering lamp or any other devices that, of course, not applicable to plastic.

Heat pipes from the inside

To get rid of traffic jams in sewer pipes, you will have to take into account a number of features. First, such communications, as a rule, have a rather large diameter, which allows you to produce warm-up and from the inside better. However, the amount of accumulating ice in them will be significantly larger, so it will require a greater heat consumption of heating devices.

For defrosting pipes from plastic, one simple device will be required. We take a board with rounded edges and freamed at her TEN in the form of the letter U. Outside the board only the heater loop should speak. All other parts should not be contacted with the walls of the heating instrument.

Having determined the thickness of the plug and the distance to it, to the ends of the TEN, fix the wires of the corresponding length, and the entire design is fastened to the segment of a metal-plastic pipe, which our fixture will push into the sewer.

Introducing the design to the sewer is needed from the receiver, where there will be a melting liquid. First, the TEN is fully promoted to the place of work, after which it is connected to the network. Moving adaptation forward as the plug is thawing, the device is periodically disconnected.

Steel pipe fixture

One of the most effective methods for removing frozen plugs in the pipes is the use of an industrial instrument. However, it only applies to products from metals. To defrost the plug to two ends of the frozen pipe, terminals are mounted for which the current is supplied. Gradually heating, the pipe begins to melting the ice clock inside it.

The duration of the defrost of the pipe will depend on its length and diameter. For example, for pipes with a cross section of up to 6 cm and a length of 23 m, about 1 hour of operation of the device will be required. If the diameter of the pipeline is greater than this indicator, then running between the terminals make less. This also applies to segments with measuring instruments and inserts. The prerequisite in this case is the presence of pressure inside the pipeline.

Along with the generally accepted ways to defrost plumbing pipes, polyethylene products can be pierced by three more "people's" ways. They are all pretty effective, though, only on pipes with a small cross section.

Spring hot water

It should be noted here to immediately note that you will not succeed in the pipe with hot water - you will have to work hard. To supply hot liquids to the ice tube, a flexible hose or a thin tube will be required. For example, if the plug was formed on a direct section of the pipe with a diameter of 25-30 mm, it is possible to use a thin metal-plastic tube with a cross section of 16 mm.

Stringing a thin tube, it is gradually pushed into a plumbing until it reaches an ice cork. Next begin the supply of hot water. Melt water will be poured on the gap between the water supply and the working tube. To save, this water can be reheated and served to the plug, for its thawing.

As Ice is thawing, the metalplastic tube is gradually pushed deep into deep, while they do not completely try the plug. It is worth noting that on winding segments of the water supply, you can use only a hard hose instead of a pipe.

It is not worth it, however, use the watering hose - it is too soft and quickly splash. Optimally, gas or oxygen hoses are suitable in this case. Inland, they can be deployed by 15 meters, however, considerable efforts will be required for their pushing due to high weight.

Ordinary enema or mug of esmark

This method allows you to get rid of ice from the cases when the pipe was frozen is quite far from home, and the water supply has bends and turns. In this case, a strong steel wire, a hydroelectric and ordinary enema (Escamor's mug) will be required. All these things are inexpensive and easy to get them.

First, the hydraulic level must be combined with wire, putting them with a tape. The end of the wire wrap in a loop so that it gets rigidity. It is necessary to adapt it so that it does not stick to the sides, and at the end of the hydroeer tube should go beyond the limits of the wire per 1 cm. The second end of the tube is connected to the oxama cup. After that, the tube with the wire is filled into the plumbing until it is wielding into the ice.

Such an adaptation is quite easy and without complications will be able to pass all the bends of the pipe and get to the right place. When the hydroelar reached the right place, hot water is gradually fed into the tube from the enema. Under the pipe output, you need to substitute the water tank, which will flow from there. Gradually, the ice cork will melt, so that the device can be promoted further.

It is worth noting that this method is quite slow. The average speed is 1 meter of pipe per hour, that is, for the working day you can defrost about 5-7 meters of pipe.

Electricity

There are cases where the thickness of the water supply is only 20 mm, its length is about 50 meters, but the depth of the breakage is about 80 cm (this is very small), and in places where the earthworks are not recommended (on the roadway, for example). Communal services in such situations are recommended to wait for thaw - but this is not an output.

To defrost the plastic tube in this case, you can use the homemade device. For its assembly, you need a plug for the socket, a two-housing copper wire, a compressor and a hose for pumping water. For our example, we take the wire with a cross section of 2.5-3 mm, the automotive fuel 8 millimeter hose and a compressor for the machine or pump.

Please note that when working with electric shock requires strict safety of safety to avoid injuries. Now you can start assembling the fixture for defrosting the tap pipe.

On a small section of the wires, the external insulation is removed, the veins are separated. At first, one of the lives are cleaned of isolation, and the remaining prolonged segment of the wire neatly, trying not to damage the shell, bend in the opposite direction along the wire. Now practically in bending the wire is screwed 3-5 with dense turns of naked wire. Having retreated from this place 2-3 mm, with the second residential one they do the same manipulations. Make sure the ends of the two lives do not come into contact with each other.

On the other hand, the wire is attached fork and "Bulbuiler". Such an aggregate supplies an electric current directly into the water, as a result of which the reaction occurs with the release of a large amount of heat. Ideal in this case, and what is happening only the heating of water, and the wires remain cold, which does not threaten randomly burning polyethylene pipes.

Before starting the assembled mechanism should be tested. Lower it into the container with water and serve the current - everything works correctly if air bubbles are visible in water and hear the buzz. Please note that touching the water during the device is not possible - get a shock.

So, the wire pushes into the plumbing, following it so that it does not bend, before contact with ice. Next, turn on the device for a couple of minutes and wait until the ice starts to melt. After that, you need to turn off the device and try to promote the wire away. In a similar way, one meter of water pipeline first defrost.

Now it has come a turn to remove melt water from the pipe with the compressor to reduce the volume of water heated and avoid re-freezing the pipe. If there are special equipment on the pipe, you can screw the crane, which can be closed, as soon as water goes on the pipe. This will avoid flooding the place of work with the plug and do not pull out the wire from the pipe.

What to do so that the pipes do not freeze

After such a detailed description of the options for getting riding from ice plugs in the pipes of the water supply will be worth it to tell about the measures of preventing such an unpleasant phenomenon.

The first thing that is worth remembering is the depth of the water supply pipe breaking should be lower than the level of soil freezing in your region. The norm for sewer and plumbing communications is the depth of 1.2-1.4 meters.

Stacking pipelines near the reinforced concrete structures is better not to produce, because concrete has a thermal conductivity level much higher than that of the Earth. Consequently, near the foundation, beams or turns of the pipe will be larger than in other places. If it is impossible to bypass, it is necessary to take care of thermal insulation, for example, to put between the pipe and the foundation of the plates from the extruded polystyrene foam.

Alternatively, in the presence of additional funds for construction, a warm cable can be laid near the pipeline. You can find self-regulating cables that begin to warm the surface only under certain specified conditions.

Where water and sewer pipes are in contact with the walls of the structure, passing through them, it will be worthwhile to warm the communications with glass gamble, mineral wool or foam. The reason is all in the same thermal conductivity of the walls of the building.

If the work is carried out in the country house, the optimal choice will be water pipes with a cross section of at least 50 mm, which are not so much frightened in winter.

As for the material for water pipes, there are also their differences here. For example, polypropylene pipes are able to withstand no more than 2-3 frills, and then they begin to burst. But the pipes made of polyethylene are practically not sensitive to frost and defrost.

Please note that in cases where you do not plan to use the sewer and plumbing in the winter season, it is worth merging from the system all the water.

So, each resident of a private house can face the problem of freezing of water in the water pipeline in winter. In this situation, the best that can be done is not to waste time, but immediately begin to defrost the ice cork. To do this, you can use traditional methods, such as external or internal heating, as well as the use of industrial equipment. And you can take advantage of the folk experience and try one of the unconventional ways to defrost. In any case, how to solve the problem, you can decide only you yourself.

How to defrost a water pipe - 11 simple and efficient ways to combat ice

With the onset of winter and the beginning of strong prolonged frost, the risk of such an unpleasant phenomenon is significantly increasing, as the freezing of water in water heating pipelines, cold and hot water supply or in the system of home sewage.

This problem is especially relevant for residents of private houses, since their communications are less protected from frost, but, despite this, not every country housing owner knows how to defrost the pipe under the ground, inside the walls or other hidden cavities, without having It approaches and direct access.

For those who do not know, I must recall that the resulting ice cork leads to the full blockage of the inner lumen of the pipe, and thus prevents the passage and free circulation of the fluid. However, the main danger of such a phenomenon is that when the ice is formed, in the crystallization process, water is incorrectly increasing in the amount, which in conditions of limited space often leads to ruptures and cracks of the outer walls of pipelines.

How to prevent freezing pipes

The preventive solution of this problem is to initially prevent the formation of ice traffic jams throughout the water pipelines. For this, during the laying and installation of engineering communications, I advise you to not ignore the requirements of the construction standards and rules, and fulfill the elementary councils and recommendations set out in regulatory and technical documents and prompted by experienced builders.

1. The minimum depth of laying a water or sewer pipeline must be located below the greatest depth of the soil freezing for your region, in accordance with the requirements of SNiP II-G. 3-62 "Water supply. Design standards ";

1. When laying outdoor or underground communications, it is necessary to use water pipes with a diameter of 48 mm and higher, because thinner pipes are subject to rapid freezing throughout the thickness;
2. If possible, I advise you to use pipes and fittings from polymeric materials (polyethylene, polypropylene) for these purposes (polyethylene, polypropylene), since they are more elastic, which allows them to stretch slightly in case of deformation, and in addition, these materials have less thermal conductivity;
3. I also do not recommend laying the pipeline in the ground, close to building structures from brick and monolithic, since their thermal conductivity is significantly higher than the thermal conductivity of dry soil;

1. To protect the outer and underground pipelines, it is necessary to use heat-insulating sleeves or segment linings made of polypropylene, polyurethane foam or extruded mineral wool, and in those places where the pipe passes through a concrete foundation or a brick wall, it is necessary to apply a double layer of heat insulating material on it;
2. In unheated private houses of seasonal living, it is impossible to leave water for the winter inside the pipelines and other communications, so with the onset of the first cold it is necessary to completely merge.

If these measures were not enough, or they were undertaken indefically, and the water in the pipes still frozen to minimize the likelihood of unpleasant consequences in the form of burst pipes, locking valves or fittings, then the reader will offer a simple instruction in which I suggest a few simple Methods for eliminating ice jams in water pipes.

To ensure guaranteed protection against freezing, in the regions with a cold climate I advise you to use an electric warming cable to be put along the entire length along the pipe and shut-off reinforcement, under the heat insulation plating.

How to defrost outdoor pipeline

If the frozen area of \u200b\u200bthe water pipeline is located in an open place, in the zone of direct reach, the solution to the icy plugging problem is substantially simplified, since for this you can use external heating of the pipe.

As a source of heat for the outer heating of metal-plastic, polyethylene or polypropylene pipes, only electrical heating appliances are allowed, for example, a construction or household hairdryer, an electric heating and a heating cable. For heating naked metal pipes without external heat and waterproofing, in addition to the devices presented, you can also use an open flame from the gas burner, a soldering lamp or a homemade improvised torch.

1. First of all, it is necessary to determine the location of the foundation of the water pipeline, and to open the tap of the nearest plumbing probor to provide free drainage of the outflow of water;

1. Before defering the heating pipes, you need to turn off the heating boiler, make sure that there is no water pressure in the system, run the circulation pump and a slightly open the drainage of the drainage of the heat carrier from the heating circuit;
2. Connect the heating device to the network, or light the flame of the gas burner, and from a safe distance to begin to warm the frozen section of the pipe, gradually moving the tool from the drain crane towards the submarine riser;

1. When using an electrical heating or heating cable, you need to evenly wrap it around the frozen pipe of the pipe, and turn on the network. To enhance the effect, I advise you to climb a thick tissue or an old blanket over it;
2. After a while, as the temperature increases, a thin strik of water will appear from the axle crane, which indicates a gradual exhaustion of ice, and after the pressure will increase dramatically, you can turn off the heating devices.

If the outstanding area is located in the apartment, it is possible to use hot water to heat it, watering a pipe or a battery from the kettle, having previously wrapped it with a thick cloth, and substituting a wide bowl or a basin under it. Also in the house, instead of a hair dryer, you can use a medical lamp with a deflector, or a household electrical heater.

How to eliminate ice cork in sewage

In private houses of permanent residence, the freezing of sewer pipes - the phenomenon is quite rare, since with continuous use of sewerage, a positive temperature is naturally maintained in the drain system, due to its own sewage heat.

However, if for any reason it happened, then I will tell you how to defrost the sewer tube in a private house using simple and affordable, but at the same time effective ways.

1. In cases where the drain collector runs at a small depth, if the conditions on the household plot are allowed, over the intended place of the soil freezing, you need to light a bonfire, and maintain the fire until this section of the Earth is fully reached;
2. If the ice cork is located near the drain of the sink or toilet, I recommend pouring a saturated hot solution of a salt salt into the sewage system (1 kg of salt on 10 liters of water). The resulting brine has a sufficiently low melting point (below -22 ° C), so the ice when contacting it takes into the reaction, and begins to actively melt;

1. If the plug is located far, you can take a plumbing cable, and to climb a flexible rubber hose to it in several places. After that, the free end of the cable with the hose to start in the sewer pipe until it is reproached to the ice plug, and then with the help of a wide funnel to flood hot salt water into the hose;
2. With a significant distance septicity from the house, the ice cork can be formed at the end of a drain manifold. In this case, you need to open the weeding suit of the septica reception chamber, to the sewer pipe to begin the flexible rubber hose to the stop, and feed water from the hot water system to completely interleeping the ice.

If the house remains a segment of an electric heating cable of sufficient length, it is necessary, as far as possible, to start in the drain hole of the sink or toilet bowl, and connect to the electrical network (the drain system should be filled with water).

Towing hidden plastic pipes

Currently, pipes made of polymeric materials (polyethylene, polypropylene, PVC, metal plastic) are used everywhere to bring cold water to home from a well or centralized water pipeline, as well as to perform an intrama wiring. The freezing of intra-quarter communications is rare, but if the pipe with water is laid under the ground, it is laid inside the wall or passes through a displeased underground space, upon the occurrence of long-term frosts, it can freeze.

The methods described above are not suitable in this case, so I'll tell you how to defrost polypropylene pipes if they are not in sight, and there is no direct access.

1. First of all, you need to purchase a bay of a two-tier electrical cable of sufficient length, with copper monolithic cores. I used to use the NYM 2x1.5 mm² power cable for these purposes, worth 20-35 rubles / mp, but it is possible to take its domestic analogue of VG 2x1.5 mm², the price of which is 16-25 rubles per meter.

1. One of the free ends of the cable must be separated as shown in the figure below. On a plot of 80-100 mm long, it is necessary to completely remove the upper insulation, then fully shock one copper core. The second core to clean up to half, bend it back, and make several turns of the bare wire around;
2. Fully cleaned custody also turn back, and trying not to damage the isolation, to wind by several turns to the very end of the cable;

1. The prepared end of the cable will start in the plastic tube, and push it forward until it flips into the ice tube. After that, connect the free end of the cable to the electrical network;
2. When the electric current is passed between two copper windings at the end of the cable through the water in the pipe, it will begin to heat up, and gradually pull the ice;
3. The shut-off valve at the entrance to the house, while you need to keep half-open, and under the free end of the pipe to substitute a bucket or a bowl, because after some time it will begin to flow out of the water.

Once again I want to recall that such a method can be used exclusively on plastic pipelines with plastic locking reinforcement, because even if a steel pipe or a metal fitting will be installed on some site, it can lead to a short circuit.

Defrosting the hidden pipeline made of metal

Despite the widespread dissemination in the modern construction of polymeric materials, metal pipes are currently not less popular. Since the technology described in the previous section, it is unacceptable to use the technology for defrosting metal pipes, I offer the reader to get acquainted with two similar ways that can be used to thaw hidden underground or in the wall of engineering communications from metal.

1. The first of these methods resembles the previous one, however, instead of an electrical cable, in this case a thin flexible hose is used, in which hot water or saline solution is supplied directly to the place of formation of ice cork;

1. In order for the hose to be climbed, did not get stuck and not bent as it moves inside the pipe, it must be closed with a tape to fine, but rigid steel wire in several places, after about every 600-800 mm, and so that the wire does not cling to bends and turning , it should be beaten with a small hook inside the hose;
2. After one end of the hose reaches an ice cork, to another end you need to attach any suitable capacity, preferably with a crane, to which you need to gradually pour pickle or clean hot water;
3. As a water tank, I advise you to use the Medical circle of Esmar, or simply speaking, the usual enema. All other actions need to be performed similarly to the previous method using an electrical cable;

The second way, in my opinion, is much easier, because it does not require partial disassembly of the pipeline and dismantling the shut-off reinforcement with their own hands, besides, it can be carried out without further human participation, but it is quite energy-intensive, besides, a welding machine is needed.

1. First of all, it is necessary to roughly define the pipe of the pipe on which an ice plug was formed, after which it was formed from two sides from this site to remove a small part of the thermal insulation, and clean the metal pipe to shine;

1. To the stripped places to attach electrical cables connected to the secondary winding of the welding transformer, while it is important to provide a high-quality electrical connection;
2. Install on the welding machine the minimum current value of the working stroke, and connect it to the electrical network. When the low voltage with high current for metal pipes is passed, they will begin to warm up along the entire length of the connected area, which will lead to a gradual depression of ice;
3. Heating can occupy up to several hours, and at this time it is important that the building of the water closest plumbing device is opened in the house.

When working with a welding machine, it should be borne in mind that connecting and disconnecting the power cables of the secondary winding to the pipe is allowed only when the transformer power is turned off, otherwise, the electrical arc is formed at the time of breaking the chain, which can cause rogues of hands and eyes, and even lead to Begging the walls of the steel pipe.

Conclusion

Summing up, in my experience, I can say that each of the methods described herein, in one way or another is quite effective, but if any scenario, it is necessary to understand that the process of defrosting pipes can take away quite a lot of time and strength. Therefore, I believe that any problem is always better to warn in advance than in winter, to suddenly stay at an indefinite time without water supply, heating or sewage.

More detailed, all the described methods described methods can be viewed in the applied video in this article, and if after viewing the reader questions will appear, I will always be happy to answer them in the comments below.

Winter frosts are a test that has to withstand not only living beings, but also engineering communications.

When violating the rules of laying pipelines in the winter time, they often occur their movement and then the problem will be in full growth, how to defrost the tap pipe?

Causes of water freezing in pipes

As a rule, the cause of the movement of water in the pipes is the elementary violation of the installation technology of the water supply. For example, if the pipes were laid without taking into account the depth of the primer of the soil in this area.

Or was ignored by the requirement to warm the pipes. It happens that the pipes will move not only in external networks, but also in the room, if there is no heating.

How to avoid moving pipes?

In order for the defrosting of water pipes, the following requirements should be taken to ensure that when installing the pipeline, the following requirements were completed:

• When underground pipeline laying, ditch to depth, which exceeds the level of soil freezing in the area.
• Do not lay the pipeline of the water supply near reinforced concrete structures. The fact is that the thermal conductivity coefficient of concrete exceeds the similar indicator for the soil, that is, when laying pipes in the immediate vicinity of elements from reinforced concrete, the probability of freezing water in the pipes increases.
• It is advisable to mount pipelines complete with a heating cable.
  This, of course, will lead to the rise in price of the installation, but it will forever allow to get rid of the problem of moving.
• In places in which the pipeline passes through the wall of the building, the insulation of glass gamble should be used to avoid direct contact of the pipe with the wall.
• In the pipes of small diameter, the water moves more often, therefore for the water supply, it is desirable to use pipes with a diameter of 50 mm.
• When laying pipelines in unheated rooms and on the streets it is best to use pipes from polyethylene. Such pipes are well tolerance and defrost, in contrast to polypropylene, which may be unusable if they move one or twice.
• If the water supply or sewer is assumed to be used only periodically (for example, in the country), then at idle time, it is desirable to fully release the system from the water to stroke there was nothing.

Methods defrosting metal pipes

There are several ways. They will be described below.

But when choosing any of them, follow the following general rules:

• When the pipes are heated, it is necessary to keep the water tap open to the outflow of water can go out.
• It is forbidden to produce a sharp heating of the frozen section of the pipe, starting with its middle.
• Heping is conducted from a water tap towards the riser. But if it requires to warm the pipes of the sewage, then you need to move in the opposite direction, that is, from the riser to the point of the watercraft.
• It should be searched for heating pipes after the location of the frozen plot is evaluated. This will help you choose the method of defrosting.

All methods can be divided into two large groups, it is:

• Methods based on outdoor exposure to the pipe.
• Methods with an internal method of defrosting.

Consider how to defrost water pipes using outdoor exposure.

This requires the use of some heating device, it can be:

• Blowtorch;
• Construction hairdryer;
• Electric heating device.

When using a soldering lamp in the room, fire safety measures should be taken.

In particular, it is necessary to install a metal screen for the pipe to protect the walls.

Using any of the listed fixtures, should be methodically affected on the pipe. The success of the measures taken will be evidenced by water, which will appear from the consumable crane.

We should not forget that when freezing the water is expanding in volume, therefore the likelihood is that after moving steel pipes will be damaged.

After the water is an impetus, it should be carefully inspecting the pipeline for the identification of leaks.

The safest and very effective way of defrosting the pipes by the method of external exposure is the use of heating electrical tape or heating cable.

In this case, it is necessary to simply wind the ribbon on the frozen plot and turn it on.

For defrosting steel pipes, this method can be used: the welding machine is taken, and it connects to different ends of the frozen area.

As a result, the pipe is heated. When using the welding machine, it takes 2-4 hours to the entire process depending on the length of the frozen area.

How to defrost a pipe from plastic?

Recently, steel pipes for the water supply device are still applied less often, they were replaced by plastic pipes. Such pipes are not subject to corrosion and are not destroyed in case of freezing of water in them.

However, if you have an ice traffic jam in them, almost all external impact methods cannot be applied to them. Naturally, the use of open fire for heating plastic will result in the destruction of the pipe, and the use of a constructional hair dryer is often ineffective, since the plastic does not conduct a heat.

Connect to such pipes the welding machine is also completely useless, since the pipes do not conduct an electric current.

Mechanical method of impact, that is, the elimination of the ice tube using the introduction inside the steel rod can be effective with a small freezing area, however, its use creates a serious risk of damaging the pipe.

Thus, if necessary, the defrost of pipes from plastic remains the only way - the use of hot water poured inside.

Below will be several ways to defrost pipes from plastic. All of them are quite effective, however, it is advisable only on small-diameter pipelines.

The first way of defrosting is to organize hot water to the freezing site.

This is done like this:

• For defrosting plastic pipes, a pipe or high rigidity hose of smaller diameter should be prepared.

To remove the ice plug in a pipe with a diameter of 20-30 mm, use a pipe or hose with a diameter of 16 mm.

• If the damaged area of \u200b\u200bthe pipeline is straight, it is more convenient to use the metal-plastic pipe. In the event that the frozen pipeline has turns, the use of the hose is required.

Conventional watering hoses to perform this operation are not suitable. The fact is that they strongly soften under the action of hot water, so push them further will be problematic.

For defrosting, gas or oxygen hoses should be used.

• Metal-plastic pipes are sold, as a rule, rolled into the bay. Therefore, the pipe should first be dispersed, and then start promoting through the pipeline, pushing an ice plug before the stop.
• Now you can pour hot water into the pipe, trying to maintain the highest temperature.
• The exhausted water will flow at the site of joining pipes, so there should be a tank for collecting.
• As ice melts, the plastic tube will need to push further, until the problem is completely eliminated.

This method of defrosting is good if the ice cork was formed on a plot located near the entrance to the pipe. If the pipe frozen far from home and on the pipeline section there are turns and bends, then the pipe is pouring inside the pipeline.

• To carry out the work, it will take a hydroelectric system, the bay of steel wire, the diameter of which is 2-4 mm, and the Esmark mug, that is, the device, which in medicine is used to conduct cleaning enema.
• We take a pipe with a hydraulic line and wind it with a wire or attach the wire to the tube with a tape or tape. It is necessary to make it so that the wire does not stick to different directions, while the tip of the tube must perform one centimeter.
• Now the second end of the hydraulic tube is connected to the withdrawal nozzle of the circle of the Esmark and begin to push our construction into the pipe.
• Since the hydrophurone tube is characterized by a small diameter and weight when pushing it does not arise difficulties, even if there are turns on the way.
• Pushed the phone should be pushed until the tube is stolen into the tube from ice.
• Now in the circle of Esmar, we pour hot water and open the feed valve.
• As the ice cork decreases, the phone should be pushed further.
• To collect the flowing water at the junction of the pipes, you should install a suitable container.

This method of defrosting is quite effective, but takes time. In one hour of work, you can have time to free the ice from about 0.8-1.0 m of the pipe.

So, there are several fairly effective ways to help solve the problem, how to defrost plumbing pipes. However, they are all time-consuming, so it is more correct to take the necessary measures, for example, when and preventing the movement of water in the pipeline.

Pipes freeze for various reasons: insufficient laying depth, no insulation, small amount of water transported, use of pipelines during frosts. The defrosting of the water supply in an affordable place does not cause difficulties. The question of how to defrost the plumbing plastic pipe underground, requires attention.

Now for water supply, high-density polyethylene pipes are used, which does not deteriorate during freezing, has anti-corrosion properties and does not conduct an electric current. But the heating of the water supply is not possible by all available methods.

Sparkling pipes with heating cable

Before proceeding to thawing the frozen water supply, find the place in which an ice cork was formed. Search methods:

1. Visual inspection. The fluid during freezing increases in volumes and leads to bloating, the place of freezing to the touch is colder.
2. Internal check. If there is no possibility of a complete inspection, use the flexible wire or cable. The plot where the cable does not go further, and will be a traffic jam.

What way to exhaust the outstanding plot will depend on the availability of free access to the problem.

Effective ways to solve the problem

Heat the plumbing pipe located in the ground is difficult. In this case, it is impossible to apply the external thawing methods. We will have to defrost the system from the inside. Consider common ways to eliminate ice traffic jams.

Application of hot water

Prepare a metal-plastic pipe, a cross section of which is 2 times less than the diameter of the main pipe. Gently move it inside the pipe to the frozen area and pour boiling water, which gradually lines the ice.
When defrosting the plumbing pipes, do not forget to open the faucet so that the pressure in the system remains low.

Heated by construction phenomenon

This method of heating is suitable for water supply, which is located in the open access. The flow of air is directed to the market. To avoid the deformation of plastic, the temperature of the hair dryer should be exhibited at a minimum level. After heating with hot air, clog the pipeline plot insulation.

Fighting icing with electric fiber

Fighting with the freezing of pipes is permissible with the help of a welding machine. But it should only apply it for thawing the water supply system from steel, copper and other metal products.

Metal is an electric current conductor. Electrons and ions under the action of an electric field, moving and confronted with each other, form energy. The latter turns into heat.
Plastic current does not spend. Therefore, we use the welding apparatus on plastic products is meaningless and irrational.

Soldier boiler for plastic pipes

Water due to the content of salts is an electrolyte. Therefore, to heat it, a pair of electrodes are required. This method is suitable only for water supply system from polyethylene and is based on the principle of boiler.

It will take: a two-housing wire of copper and steel wire, tools. Wire veins are cleaned and wrapped around the wire. Make sure that the turns do not come into contact with each other, since the closure can happen. A plug is attached to the free end of the wire.
Lower the homemade boiler in the pipe to the plug from ice, turn on the network. Through time, the plumbing warms up, the icing melts.

How to prevent freezing system

To do this, you need to remember the following:

1. Pipes are laying at sufficient depth, below the level of freezing of the Earth.
2. The water supply should not pass along with constructions from reinforced concrete (foundation, beams and supports), since this material has a higher thermal conductivity. If there is no other place of gasket, the pipes will warm.
3. The places where the sewage is held by the wall of the building, it is recommended to warm the mounting foam, glass or mineral wool.
4. Use pipes with a diameter of at least 50 mm.
5. When choosing between products from polymers, remember that polyethylene reacts steadily to the process of freezing and defrosting. Polypropylene can burst after two defrosts.
6. If the pipeline in winter works irregularly, then it is better to drain the water from the system.

You can also if there is an opportunity and finance, lay a warming cable.

Application of heating cable

The cable is used to heat the water supply and the prevention of freezing plastic and metal pipes. Nuances to use:

• the operation time of the device should not be constant, quite night time;
• heating cable is recommended immediately when laying a pipeline section that is pregnant;
• the device is divided into 2 types: cable with self-regulating and simple function.

If the conditions of laying the plumbing system do not have to face the problem of freezing.
