How to unfreeze a pipe in the winter, the decision

Frosty winter, many owners of private houses think that pipes in their homes need extra protection from peremerzaniya and insulation. At -30 ° C and below, sometimes the water no longer flow into the faucet and start searching for the reasons for the lack of water. And when you find that the cause is not a failure of the pump and not in the absence of water from the water source, and in peremerzanii pipes ...

... go on the attack heater and heat gun, Construction and even home dryers. Bottom line, the frozen section of pipe to warm, the next morning - it all starts again. The benefit of modern technology does not stand still and already devised ways to protect pipes from peremerzaniya.

Peremerzla pipe, what to do?

You can warm the pipe in the ground as follows. About which we guessed yesterday with the client.

Inputs: 25 mm tube IPA 5 meters, frozen about a meter from one end of the other is not measured.

Necessary to bring the smaller diameter hose, so that he can climb into the pipe, stick, bring to a freezing space and feed the hot water. In this way, the water will not stand and cool at the site of freezing but will go along the tube. This is how it is seen in the picture.

If there is no long hose, then take a bucket of hot water and slowly pour hot water.

Another embodiment: Mark metal or metal-plastic tube, take a hair dryer with a nozzle diameter of the tube, push tube into the pipe and to supply air dryer. I think so even more effectively.

Metal or cast iron pipe can be powerful to warm hairdryer construction or burner.

Problem areas of the pipeline

Basic pressure points auxiliary washer, is output from the main pipe of the well and its entry into the house. It is important to consider the entire piping system to avoid errors. Pipes from the well to the house laid to a depth of not less than 1.7-1.8 m Required pipe wrap in a bilayer coat -. In insulation and sheath a sewer pipe 100 - 110 mm, it is placed in sandwich water pipes and insulation.

Complicated when water is already laid, and in the course of laying was made some mistake, it will be more difficult to eliminate. Better waterway bury as deep as possible. If it is difficult, try to solve this problem by using additional insulation for pipes. If the pipe is below freezing and the depth is in the sewer pipe diameter 110 recommend further err. Enough to make several openings in the sewer pipe and through the openings to fill the foam core therein.

How to protect the water pipes from freezing

Options for solutions to prevent peremerzaniya water supply in winter

Warming houses cap:

• heated room
• Warm ground floor
• Well (well)
• insulation
• Foundation

Insulation of the basement with the installation of the heater there:

• heated room
• warmed cellar
• Well (well)

The use of heating cables:

• heated room
• insulation
• Well (well)
• Cold ground floor

The optimal solution to the problem peremerzaniya pipe - self-regulating heating cables. You can buy a ready-made with a fork and termozaglushkami certain length or to buy a heat cable by the meter, as you need, and install him shrinkable electrical cable and plug. The basis of the system self-regulating heating cable, it is able to change the power per unit length as a function of changes in the environment temperature. Inside the cable there is a special compound that with decreasing temperature begins to conduct current, thereby generating heat in the opposite direction. Hence it is called - self-regulating.

How to use the self-regulating cable

The heating cable is connected to the pipeline under the ground or to a portion of the pipe outdoors. The cable can be installed inside and outside the tubes. In the first method, you will need an aluminum tape (foil) and a heater (tilit, Energoflex). The cable is applied to the pipe above and aluminum tape is wound, thereby holding the cable to the pipe. Aluminum foil tape or necessary for uniform heat distribution over the tube. Top worn insulation. The cable is laid in a row to 80-110 diameter, with a larger diameter cable is laid in two rows. You can put the cable wavy or spiral she folded tube.

Scheme typical installation of the cable on the tube outboard fixture:

• Suspension fixture
• waterproofing
• thermal insulation
• Trumpet
• heating cable

Mounting of the cable on the pipe surface:

• a temperature sensor (optional)
• heating cable
• Water pipe
• Masking tape
• thermal insulation

Mounting of the cable inside the tube carried out in the event that if you can not put it on the surface. For internal laying special cable glands are used, which are suitable for connection to the pipe diameter of 1/2 ", 3/4" and 1 ". The heating cable is designed for indoor installation, protected against the ingress of moisture food rubber.
