In our country there are severe frosts in the winter. It is on these days that communications at home can be in serious danger. If the sewers or water pipes are not sufficiently insulated, then they can simply freeze. In this case, about any comfortable accommodation and there can be no question. How to defrost a sewer pipe underground in a private house, and what methods exist for this? That's about it and will be discussed.
At shallow depths the pipe may freeze
Before than to talk about how to defrost pipes, it is worthwhile to talk about the main reasons for the freezing of drains in them. There may be several of them, let's call the main ones:
That is why the installation of sewage must be taken very seriously. Proper installation of pipes (to the desired depth, with thermal insulation and the correct slope) will guarantee the absence of such troubles.
PVC pipes for outdoor sewage
Defrost sewage pipes can be done in different ways. The choice of one method or another will depend on several factors. Namely:
A blowtorch can heat cast-iron and metal pipes
Sewer pipes can be made of metal or plastic. The first option (which is not so common today) makes it possible to use the method of external heating. Plastic pipes can not be heated, at best, they will withstand temperatures up to 100 ° C.
The size and location of the ice plug can be determined using thick metal wire. It is introduced first from the side of the house, and then from the side of the sump or septic tank. Knowing the length of the entire communication and the penetration depth of the wire, one can easily calculate the place and size of the ice plug.
The device defrosting metal pipes
For metal sewer pipes you can apply a special apparatus to defrost. The principle of its operation is quite simple. Terminals are attached to the edges of the pipe in which the ice blockage has formed. Then an electrical current is applied to them. As a result, the pipe heats up and the ice inside it melts. But such equipment is suitable only for metal pipes.
Defrosting the sewage with an Esmarch
mug for defrosting plastic, and any pipes, you can use another way. It is longer in time, but less expensive. To defrost, you need to prepare the following devices and materials:
Defrosting with hot water
The principle of this method is that the ice is fired with hot water. Esmarch's mug (or simply an enema) is connected at the hydro level, to which a piece of wire is attached with tape. Such a device is introduced into the pipe and hot water is supplied through a mug. Consumption of the latter will depend on the diameter of the pipe. As a rule, boiling water needs 5 liters for every 5‒10 cm of ice jam.
It should be borne in mind that when hot water is supplied, it will flow out along with melted ice. Therefore, if the defrosting occurs from the side of the house, then you need to prepare a container for collecting water. If the procedure is performed from the side of the sump, then the capacity is not needed.
Another way to defrost a plastic pipe is to use a heating element. To do this, we construct a special device. On the board of the desired size set TEN. His bend should protrude beyond the front edge of the board, and the rest of it should be completely on it.
Knowing the location and size of the ice jam, we prepare an electrical cable of the desired length. Connecting it to the heater must be carefully insulated terminals. Then a metal or better metal-plastic pipe is attached to the board. She will play the role of the pusher.
This construction is placed in a pipe.It is better to do this from the side of the sump or septic tank, so the thawing water will be where to drain. When moving the heating element it is disconnected, and the supply of electricity is carried out after installation of the structure in the right place.
TEN should not touch the pipe walls.
Warming up water in the toilet
If the pipe is frozen near the toilet, you can try to defrost pipe, heating the water in this sanitary device with a heater or boiler.
In addition, metal pipes can be heated with a blowtorch. To do this, dig a trench at the place of laying the sewer. Then with a blowtorch, the tube heats up. In this case, you need to start from the cesspool or septic tank, so the water will be where to go.
