I told many times about many people about manufacturing technologies engineering systems in private houses. And all the time turned attention to the fact that the pipelines must be laid below the freezing point or carefully insulate them. However, from time to time, I am addressed to me how to defrost a plastic water pipe.
Here I remember the case, as in mid-January, a neighbor called a neighbor in the country and tearfully asked to repair the water supply. As it turned out, he is planned to hold an anniversary outside the city, and arriving at the site after a long stay in warm countries, faced the fact that water does not flow from the cranes. And all the complex electronics providing water cottage also does not work.
As it turned out, the whole wine was an ice cork, which blocked the metal-plastic tube laid underground. And since with their own hands he could only sign business papers, had to call me to help.
Of course, we coped with the problem, and I turned out to be the most honored guest at his holiday. I decided to tell you about how to defrost plastic pipes of water pipes and sewage. Suddenly the instruction below and you will have invaluable help. Especially when a reliable Plumbing friend will not be nearby.
In my practice, I rarely met people who make or order modern engineering networks (water supply, sewage) from steel pipes. Plastic is more common.
And then I consider it right, because the price of pipes from polymers is reduced all the time, and operational properties Such a solution was always at the height:
The only thing, from which it is impossible to get rid under no circumstances is the danger of fluid freezing in them. However, with this nuisance, I know for sure, people are faced only in cases where they were commissioned by an illiterate engineer.
Only such a person can pave a plumbing at an insufficient depth in the ground or not to insulate the engineering system. As a result, you come to the cottage to celebrate the birthday, and nothing flows from the crane. Sorrow.
So that this does not happen, it is necessary to dig for pipes and sewage pipes a fairly deep trench. The average depth of the primer of the soil in the region of Moscow is 1.4 meters. However, this indicator depends on many other factors, therefore, to determine the exact value, it is better to consult specialists or use special cards with tables.
By the way, many are asked why the central water pipes in the cities do not freeze. I will answer without roller. There, the water current does not stop around the clock, so the fluid is in motion does not turn into ice.
And at the cottage, the pumping equipment is turned on only from time to time. Therefore, it is necessary to take measures to insulate water-transport pipes.
Special attention is paid to insulation and bundle the drain systems where water flows at low speed. Otherwise, a plug is formed and you will have to decide how to defrost the plastic sewer tube. This occupation is complex and far from pleasant.
If for some reason the ditch of suitable depth does not work out, it is necessary to bite the pipes into thermal insulation materials or invent their heating systems. Or use both options.
If you know that the pipes are insulated with you badly, and at night they promise a very strong frost, leave water overnight included to ensure the flow in the pipe.
In this case, the probability of ice appearance significantly decreases.
But often it happens that people return to questions about the insulation of pipes only when they have already encountered the freezing of water. There is nothing left, you will have to pull the ice. I'll tell you about it now.
First we will analyze how to defrost the plumbing plastic pipe underground. This, in my opinion, the most time-consuming and long process. Especially in winter, when not only water in the pipes frozen, but the land itself, where they are laid.
The simplest scheme is as follows:
The advantage of this method is that not only water in the pipe should be warm up, but also to hide the earth itself. And we need this in order to go to the next item of our work.
If you once faced the freezing of water, I recommend to remake the engineering system in the summer. After all, not always in time your friend will come to the rescue and hangs this pipe. It will be necessary or deepen the trenches, or insulate the water transport system throughout its length.
By the way, once someone told me that he insulated with empty plastic bottles. Scheme such:
The essence here is that the air that is inside has a low thermal conductivity coefficient and will not give water in the pipes to freeze.
What to say here. In my opinion, you will spend more time to collect bottles than to work. It is better to go to the store and buy basalt shells. It will be pure, carefully, effectively and not very expensive.
And to all folk recipes I have recently resorting more often. Is it just confident in their effectiveness.
Another way to eliminate Ice Cork - Use hot water. The minuses here I see several at once:
Nevertheless, sometimes I resorted to this method. So that it was more efficient, the ladies of several own tips, which were formed during the work:
Another proven method that I sometimes used to catchpipes. It must be implemented carefully, as you can get a blow to an electric shock. Nevertheless, I will describe the technology, suddenly another way to eliminate the problem you will not.
Scheme such:
Remember that the fat water must be drained all the time, otherwise it can freeze again.
Special devices exist for thawing pipes. We are talking about steam generators, autoclaves and hydrodynamic devices. It is not necessary to buy them, it is enough to take the necessary unit for rent in a specialized construction supermarket.
Work occurs as follows:
And if someone advises you just bend the wire and break through the ice, you do not need to do this. So you are with a lot of probability damage the plastic shell of the pipeline, but not an ice cork.
As you understand, defrosting plastic pipes, laid open (for example, in the basement, pantry or other unheated room), It is much easier. There you will not need a specialist help at all. Especially if you follow my advice.
The easiest way of heating is a construction hairdryer or other similar source of heat. Directing the flow of air to the engineering system, you gradually heated the walls of the pipes that give their thermal energy water. And ice melts.
By the way, the hairdryer can be replaced by the usual heater, which is placed near the pipe.
You probably saw how metal pipelines warm solder lamps. So, this method of heating is categorically not suitable for plastic. The polymer has a very low melting point (about 140 degrees), so the flame from the gas or gasoline burner melts not only the ice, but also the pipe with it.
Naturally, the mandatory step of any defrost is the insulation of pipes or the installation of heating elements that support the necessary fluid temperature. I offer several options to choose from:
And it is best to wind pipes with a cable, and then insulation. The combination of these methods will provide you drinking water At any time of the year, regardless of the temperature "Overboard".
Separately, I will tell about the method of removing the plug from the drain pipe of the external sewer system of the private house. It is with this problem that most residents of private country houses face.
So, to eliminate the problem you will need:
Eliminated a similar problem I am:
As in the case of a water supply to avoid plum freezing, you need to lay pipes on the desired depth Or insulating them with thermal insulation materials. It is better to spend time and money in the summer than to dig in the waste in winter, on the eve of his birthday.
Regardless of the selected method of defrosting and the method of laying pipes, I will give a few more tips that need to be held while thawing pipes:
There are a lot of ways to defrost pipes and anyone who came across a similar problem knows its way of thawing ice. I would be glad if you shared them with our readers, describing in the comments to this article.
And I suggest everyone to familiarize yourself with the video in this article, where you can find many other tips regarding the operation of engineering systems of a residential building.

How to heat the pipe in the ground? In winter, water in pipelines often freezes. This can occur for various reasons. For example, if the depth of the pipeline is insufficient or inefficiently arranged insulation. Freezing of the pipeline can occur in winter with very strong freezers. The pipeline to which there is access is easy to defrost. For example, it can be deflated by a household hairdryer. But what to do with pipes that lie underground in the distance from the house?
If the pipeline is frozen on entering the building, you can simply warm the wall. But there are cases when the water pipe has frozen 10-20 meters from the house. If it is made of metal, it is warm enough quickly. This requires a welding machine. It must be connected to different ends of the pipeline.
With the help of heating with the welding machine, the water in the pipe can be in 3-4 hours.
The duration of work depends on the length of the pipeline.
How to defrost a pipe from plastic? Currently, plastic structures are manufactured, which maintain the pressure to 10 atmospheres, easily carry freezing and are not subject to corrosion. Plastic pipes do not conduct an electric current, and therefore, it is impossible to defrost them with the help of a welding machine. Punch ice mechanically using steel wire will not work either. Often the length of the frozen plot is more than 5 m. Therefore, the only output is to melt the ice with hot water. If the hot water is simply pouring into the pipeline, the ice cork will not melt from it, and the hot water will not go inside.
Therefore, it is necessary to feed hot water directly to the icy territory area. This can be done using a pipe of smaller diameter. For example, if the plastic pipes have a diameter of 32 mm, the area on which the ice tube is located straight, the pipe must be from the metal plate with a diameter of 16 mm. It is necessary to straighten the pipe of a smaller diameter and put it into the pipeline until it gets to the ice tube.
Then the hot water is poured into a smaller tube. In the gap between the smaller and the larger pipe will flow cold water. This water can be used, it is heated and poured into the system again. It is necessary that the ice cork is eliminated. As an ice cork will decrease, you need to push a smaller pipe further.
If the water supply has sharp bends, in this case you can use a hard hose. A simple irrigation hose for this will not suit, because it softens from hot water and it can not push it on. Therefore, it is possible to use an oxygen hose that serves gas cylinders. It has sufficient rigidity, but it can be stretched from entering only 15 m. It is moving through a pipeline with difficulty, as it is too heavy.
How to defrost the pipe right? If the pipe has 2-3 turn and frozen 20 meters from the house, you can apply a more efficient technique.
Materials and tools:
First, the hydroeer tube is equalized, with its help align steel wire. Then the end of the wire is screwed to the hydrorevel tape. The end of the wire for greater strength can be beatened. It is necessary that the wire is not sticking out and in front of it 1 cm performed the end of the tube. After that, the hydroelar is connected to another end to the circle of Escam. The wire with the tube is pushed into a plumbing pipe until they get to the ice cork.
The hydraulic tube has a small diameter and little weighs. Therefore, it easily passes in the pipeline and overcomes all turns. After that, the water is heated and fed into the pipeline with a circle of esmark. Substitute a bucket under the tap pipe. How much hot water is poured, as much cold water and comes out of the pipeline. The wire with the tube is pushed as the ice plug melted. Such work is performed long. It takes 1 hour per 1 m frozen system. Therefore, to defrost 6 m tubes, you need to work all day. Pour no less than 10 liters of hot water. Then pushed the phone. This method is often applied in practice and leads to positive results.
Materials and tools:
Take a two-hood copper wire and remove insulation from it. Of two wires inside, one are offended, and the other is bend along the wire in reverse side. Then the bare wire makes 5 turns at the very edge of the wire. Then at a distance of 3 mm from the end of the turns, the other wire is broken and wound up in the same way. It is necessary to ensure that the wires do not come into contact with each other. Otherwise, a short circuit may occur.
Attach the plug to another end of the wire. So make a device for heating. When the device is turned on, the current passes through the water. As a result, a reaction occurs and a significant amount of heat is distinguished. During the operation of the device, only water is heated, and the wires are not heated. Due to this, the plastic pipeline can not be paid.
You need to stick the wire into the pipe until it is stripped into the ice cork, do not press much so that it does not bend. After that, include the device into the socket and pressed onto the wire. The heating process begins. Then you can choose excess water compressor to spend less time to warm water. The product will be dropped through enough long time. The pipe with a turn is sometimes heated within a few days.
After the pipe is unfolding, you need to take care of that it does not frozen again. For this it is necessary that a certain amount of water constantly passed through it. Therefore, it is necessary to open the crane more often and use more water. At night, you need to leave a thin stream of water in the water supply. While water through pipes flows, the risk of re-freezing decreases.
To avoid freezing water in the pipeline, it is necessary when laying pipes to have them at a depth, which is below the level of primerization of the soil. After laying, the pipeline must be inspired. Then the pipes will not freeze the pipes.
Lapped pipeline - sewage, heating system or drinking water - With a high degree of probability, it can freeze together in the winter, that is, speaking by a professional language - to know. Such a situation is the defrost of heating pipes or other trails - often it happens if local climatic realities were not taken into account when laying the track, or the conditions for laying pipes were simply broken.
So, without thermal insulation of any communication pipes, they can deficulate in large frosts. This also applies to underground and terrestrial communications with liquid. Output one - you need to warm the tracks on time. But what to do if the track has already frozen, and requires a piping defrost? Life experience gives quite a lot of thawing techniques with their own hands, and cheap, and expensive, but always - effective.
Reliable blocking of pipelines occurs on the available or open areas of the track - it is often enough to use a powerful stream of hot air, for example, from construction fabric. But here is the thawing of underground communications - the question is much more complicated, and sometimes very original technologies are developed here, for example, the Esmar mug, which will be described below. 
The main methods of defrosting the heating or water pipes are in the use of common sweater tools and materials: a soldering lamp, hot water flow, blowing with a construction or household hairdryer, etc. Here you need to clarify some points:
Based on these restrictions, consider the traditional technologies for defrosting the heating mains and other pipelines.
Since methods for defrosting open heating pipes, sewage systems Or we understand the water supply, we consider the outer defrost of underground trails, which is immediately complicated by the fact that the pipes will need to be excavated. The technology depends on the diameter of the pipe and the length of the frozen plot - you can dig a manual, and maybe you will have to rent an excavator. 
After digging the trench and opening the pipes, determine what the pipeline was insulated - the technology of its defrost will depend on this: for example, polyethylene pipes It is impossible to warm the open flame or current. The temperature of the hot air jet from the hair dryer or a fan heater should not be greater than 100-110 0 s so that water in the pipe does not boil and bore it.
Steel or cast iron pipes can be warm up the solder lamp or gas burner, Kostroma or other sources of open fire. 
Detergenting of sewage pipes, unlike heating or water supply, has some features. Large diameter PVC pipe Allows you to warm them from the inside, and this is a plus. But the pipes can be clogged not only with frozen water, but also garbage, and it is a minus. Therefore, the discharge sewage must not only be shanmed, but also to be asked.
For defrosting from the inside plastic sewage Collect simplest homemade device: to U-shaped tan with bend diameter, a slightly smaller diameter of the pipe, connect the cable and attach it to the metal plastic pipe Ø ½ '' of the desired length. Most often, the distance to the place of the frozen plot is known, so it will be easy to calculate the length of the cable and the length of the guide MP tube, even visually. After that, the device is connected to the network and pushed it into the sewer, as shown in the picture: 
It is necessary to start the promotion of the heater, on the part side of the drain, so that melting water can fire freely. In the same way, a large diameter plumbing can be skewed.
It will be effective to defrost from steel or cast-iron pipes With the help of special industrial equipment. The principle of operation of this device is as follows: Terminals for which the voltage arrives, the pipe under the action of the current is suggested, and water thaws, connected.
For example, you can bring the following data: steel pipe 25 m and Ø length< 6 см оттает за 40-60 минут. Если диаметр трубы больше, то клеммы подсоединяют на более коротких участках, при этом нужно следить, чтобы в трубе находилась вода под некоторым давлением – это касается разморозки отопительной и plumbing systems. 
The use of hot water implies one feature of the behavior of the ice: the ice cork will not miss the hot water into the pipe, if you simply pour it from above. Therefore, hot water is served inside the frozen area using a hose or a pipe of a smaller diameter. For example, when defrosting the direct section of the water supply line Ø 25-30 mm will be effective to use the segment of a metal-plastic tube Ø 16 mm. 
The inner tube must be direct so that it can be shoved into the plumbing to the depth of freezing. As soon as the tube flies into the ice, it can be filled with hot water. The flow of melt water will be through the slot between the pipes to pour out, while at the same time increasing the clearance. The ice will melt from all sides of the cork, freeing the place to further promote the metal-plastic tube on. If the frozen plot has bends and turns, then instead of the tube use a flexible, but hard hose.
Country hose for watering is not suitable for defrosting - from high temperatures It will become soft, and it will not be able to push it on. The best oxygen or gas hose is suitable for this purpose, which are connected to cylinders with gas or oxygen. Practice shows that such hoses can even be softened to push up to 15 meters away. A certain difficulty will be represented by the fact that the hose remains solid. 
But so far we have considered easy cases - defrosting on straight and short plots. And what to do if the pipe frozen is a few dozen meters from housing, and while still a complex route - with turns and bends horizontally or vertical?
Such comfortable problems The use of the Esmark mug is solved complete with a construction hydraulic level and a stiff steel wire. You can buy all these components without problems, the cost is small, and the effect of application is one hundred percent. 
Water and water level tube are aligned and connected by their ends on one side of the device. Wire for greater rigidity and passability inside the pipe bend at the end, making a small loop. The hydraulic tube must be 1-2 cm ahead of the loop of the wire. The other end of the water level tube is connected to the circle of esmark, and the tube with a wire is hosted until it stops into the pipeline.
Further in the water level tube it is necessary to pour water - a kind of hot "enema". Do not forget if thaw the pipe indoors, substitute some container to collect meal water. The volume of the container is simply determined - how much will you cover the hot water into the device, as much and poured out of the pipe of the cold liquid.
As ice melts, the tube is pushed further - until the ice plug is completely disappeared. This technology takes a lot of time (1 m. Per hour), but very efficient and unfortunate. 
In order not to apply all the above techniques, you need to make prevention preventing the freezing of water pipes:
Since in the winter of the hosts of private house-building and apartments sometimes face the need to defrost pipes with water, it must be remembered that the faster you respond and take the necessary steps to extend the pipeline of any destination, the smaller part of the route will fail. For defrosting pipelines, all methods are good and traditional, and invented by vitality - your comfortable further accommodation in the house depends on this.
Held with violations that in winter time It leads to freezing pipes and impossibility to use water.
To disorders in water supply leads:
Note! Before defering the water pipe, you need to take into account, from which material it is made, and where exactly the frozen section is: indoors or on the street. Depending on this, the methods of defrosting pipes will be varied and, accordingly, the tools used.
To defrosting the water supply from plastic pipes, it is necessary to begin extremely carefully. Methods for thawing pipes can be varied depending on the location of the frozen area.
Note! The defrosting of the ice cork should be started on the side of the crane.
The plot of water supply, located directly in the building, can be deflated as follows:
Note! It should be started first with cold water, to avoid cracking the plastic pipe.
When thawing the water pipeline at home, it is necessary to eliminate damage to the system due to the pair of pair defrosting. To do this, open a crane and watch when water flows out of it.
The defrost of plastic pipes outside the house depends on where they are laid - above the ground or in the ground. In the latter case, it is necessary to provide them with full access. The thawing can be carried out in the same ways as in the room - with hot water and electrical appliances.
To thaw pipes outside, you can use a special heating cable. To do this, it is necessary to wrap it with a foil, winding the brass cable from above and cover the insulation - it will take a long time.
If the frozen plot is located inconvenient, it is recommended to depress the water pipe and deteriorate it with the introduction inside hot water. To do this, you may need a mug of Esmar. Simultaneously with the supply of hot water into the pipe, it is necessary to use a steel rod to introduce it inside the water pipeline and breaking the ice tube.
Methods, how to defrost a metal plumbing pipe, a little more. In the room you can use the same methods as for plastic pipes:
Outside, you can use not only all of the above methods, including a heating cable, but also special devices - propane burner or defrosting machine.
When using the propane burner, you need to follow the precautions to prevent the emergence of a fire. For example, processing the frozen section of the plumbing pipe on one side, it is necessary to put a metal plate on the reverse side.
For metal pipes Suitable use of the device with which the current is fed capable of breaking and eliminate the ice tube.
Note! Each of the ways of defrosting the plumbing pipe is quite laborious, therefore, during installation, you need to take care of the timely insulation of the water pipeline both in the room and outside it.
Instructions for defrosting a tap pipe with hot water, see below:
Why do pipes freeze? Causes can be very different: pipes are laid at insufficient depth, it is inefficiently insulated; too small volumes of water are transported, pipes are operated at extremely low temperatures. It must be borne in mind that if sparkling pipelaid in the available places, does not cause special difficulties (for example, it is possible to warm up using an ordinary household hair dryer), then how to defrost outdoor when underground strip? "Successful" if the pipe frozen at the entrance place - in this case, you can simply warm the walls. And if the freezing point is a few meters from the structure? Is there a solution to the problem or need to wait for heat? There is a solution to the problem!
If the pipes are metallic, then the defrost process is quite simple. To do this, take an ordinary welding machine and connect it to different ends of the pipe. Such a simple electrical method eliminates the problem within two or four hours. The frozen section of the pipe is longer, the longer the defrost lasts.
But what to do if frozen Plastic trumpet? Currently, networks are used primarily made from high density polyethylene (HDPE), which withstand pressure up to 10 atm. They are not subject to corrosion processes and are not destroyed when freezing. In terms of its properties, polyethylene is not a conductor of an electric current, so defrosting with the help of the welding machine is impossible. Removing the ice tube using a steel rod is also fraught, you can damage the pipe. Thus, the output one is to use hot water for defrosting.
The proposed three ways of defrosting of polyethylene pipes are "know how" folk craftsmen. However, despite its some eccentricity - they work. The only disadvantage is that they are only suitable for pipelines of small diameters.
Method 1
It should be borne in mind that the ice tube in the pipe will not allow hot water to get inside if it is easy to fill it. So you need to find a method for feeding hot water into a frozen zone. To do this, you can use a hose or a pipe with a smaller diameter. For example, if you need to defrost a water pipe with a diameter of 25 or 30 mm, and the frozen stretch is straight, then the most effective will be the use of a metal-plastic pipe with a diameter of 16 mm. First, we straighten the metal-plastic pipe (m / n pipes are usually rolled into the bay), and then you by moving it into the frozen pipe until it reaches the ice. After that, we feed on it to the place of freezing the most hot water. The exhausted cold water will be poured on the gap between the plumbing and metal-plastic pipes. By the way, if the supply of water is restricted, you can use the fatty water: to warm up and go to the place of freezing. In this case, the ice cork will melt, and you can push the metal-plastic pipe further.
But what if the frozen section of the tap pipe has bends and turns? Use a rigid metal plastic pipe in this case will not be possible. Is there a solution? In such a situation, you can use a hard hose. Note that the usual watering hose does not fit, it will soften from hot water and push it impossible. Oxygen hoses and hoses for connecting were effective in such a situation. gas cylinders. Such hoses are hard enough, but, nevertheless, they can be poured no more than 10-15 meters from input. In addition, they are sufficiently heavy and pushing them in the pipe with a significant effort.
Method 2
Akak to defrost the pipe of the water pipe, if it happened in tens of meters from the house and the pipeline has bends and turns? There is an effective and economical way. To do this, you will need a set of hardened steel wire (2-4 mm), building hydroeer and circles of esmark (banal enema). The cost of such a set is small, and many have all its components in the farm.
First, it is necessary to align the hydraulic tube and wire, and then fasten the electrical end of the wire to the hydrorevel. To ensure a greater hardness at the end of the wire, you can make a loop. The coam of the wire should not be stitching, and the end of the hydraulic tube should perform 1 centimeter before the wire. After that, the other end of the hydraulic level must be connected to an esmarm mug and push the wire with a tube to the pipeline until it stops into the ice tube. Due to the fact that the hydraulic tube has a very small diameter and very low weight, it easily moves through the pipeline, overcoming all turns. Next, fill hot water, making the frozen water supply "the enema". To collect the outflow of water under the tap pipe, it is necessary to substitute a container, because how much hot water is poured, so much cold - it turns out. As the ice melts, we continue to push the wire with a pipe of a hydraulic system. This method of defrosting pipes is quite long, approximately an hour can be deflated to 1 m of the pipeline, i.e. During the working day, it is possible to free the ice from ice 5-7 m. At the same time, it should not be in a hurry, before pushing the tube / hose, it is necessary to pour at least 10 liters of hot, with minimal cost.
Diagram of the process of defrosting pipes with wire, hydroeer and circles of Escam
Method 3.
Consider the situation when we have a frozen polyethylene plumber of small diameter (20 mm) with a length of 50 m with a laying depth to 80 cm. We note that this is the lack of depth of the water supply laying, so it is frozen. Distinctive feature - The plumbing passes under the roadway. Communals in a similar situation, as a rule, advise waiting for thaw, but, nevertheless, there is a way to do without them.
We will need the following "equipment": a copper two-tier wire (length and thickness of the section, select the length and diameter of the frozen water supply), the plug for the socket, the compressor and the hose for blowing the outflow. For example, for a pipe with a diameter of 20 mm, you can take the wire of 2.5-3 mm and the automotive fuel hose with a diameter of 8 mm, a conventional car compressor (as a pinch, you can use the pump).
We warn that using this method it is necessary to observe special care, since the work is performed using high voltage.
Now it is necessary to prepare all this to the defrost process. FROM small plot Wires need to remove the external isolation, divide it into two wires and one of them to bargain (remove inner isolation), remaining in the insulation of the wire gently bent in the opposite direction along the wire. It is necessary to ensure that the insulation is not damaged.
Then almost next to the fold of the wire you need to make 3-5 turns of the bare wire (as close as possible to each other) and crop its remaining end.
After that, to retreat 2-3 mm from the reels made, barish the second wire and crush it around the wire in the same way. The turns of the first and second wire should not touch, otherwise there will be a short circuit in the future.
To another end of the wire, connect the plug and the "unit" for defrosting the pipe is ready. In the people, this device is known as the "Bulbulator": if you put it into the water and connect to the power grid, then when the current passes through the water, a reaction occurs with the highlight of a large amount of heat. In our case, such a device is ideal, because only water is heated, and the wire remains cold, i.e. Plastic tube will not even pay randomly.
The assembled device must be checked. To do this, it must be placed in a jar with water and connect to the power. If air bubbles are departed from contacts and a slight buzz is felt - the unit works. Once again we remind you that when you contact with water while the device works, you can get a blow to the current.
We proceed to the process of defrosting the water supply. The wire must be carefully pushed into the pipe so that it does not be bent. Therefore, it is preferable to take a large cross section. When the wire rides in the ice cork, you need to turn on the "Bulbuiler" and wait one or two minutes. Now you can try to push the wire further: the ice began to melt. When it is dropped around the meter of the pipe, it is desirable to blow off the water with the help of a compressor, it is necessary to reduce the volume of heated water, and that the water supply is not freezing again at the already frostbed site.
If there is special equipment, then it is advisable to screw the crane on the pipe. When water goes through the pipe, the wire is pulled out of it, and the crane is closed, i.e. Fixing the place of the defrosting procedure (for example, basement) will not happen.
So that plastic pipes do not freeze should be remembered:
If all these conditions are observed when laying a water supply, you do not have to think how to defrost pipes.
