Water pipes are found to freeze and crack in many places, how to deal with them if they are hit?

First of all, don't panic, deal with it calmly, first turn off the main valve of the water valve at home, and then call ** to apply for repair to the municipal road pipe network department.

First of all, the water valve should be turned off, and then the repaired water pipe should be wrapped with a foam sponge and other warm materials, which can effectively prevent the water pipe from being frozen and cracked again. Warranty should be carried out as soon as freeze crack occurs to reduce losses.

After the stroke, the water should be stopped as soon as possible and the valve of the water supply should be closed. This avoids the spread of large amounts of water and then replaces the water pipes.

We can use a heating device at home, such as a small sun or a small electric heater, to thaw these water pipes.

More attention should be paid to protection, you can put a protective film on the outside of him, so that it can prevent freezing.

1. The covered sand washed away by the flood in the rainy season should be filled in before winter to prevent the soil from being too shallow and freezing to damage the water pipe.

2. Anti-freezing equipment (anti-freeze hydrants, anti-freeze wooden boxes, etc.) should be installed on the faucets and water pipes outside the house.

3. If there is ice in the house, it should also be wrapped in sack pieces and wrapped with straw ropes.

4. In the house with water pipes, the door and window seams should be pasted, and the insulation in the house should be paid attention to.

5. Once the water pipe is frozen, do not use fire or boiling water to scald, which will damage the water pipe and faucet due to sudden expansion, and the faucet should be wrapped in a hot towel to help thaw.

1. If there is water in the water pipe, the water in the water pipe will freeze in winter, and then the volume will become larger and the density will become smaller, so that the water pipe will be vigorously supported, and the water pipe will crack. In fact, water pipes without water are not cracked.

2. The quality of the tap water pipe is not good, and it is a seamed steel pipe.

3. Steel and iron products will become brittle at low temperatures, and will be weak under pressure, and will also break. It was because of this that the Titanic was sunk.

(1) Go to the market to buy a thickness insulation pipe that is more than 2 cm suitable for your own water pipe, cut the insulation pipe from the middle, wrap the water pipe tightly, and wrap it with tape or cable tie on the outside.

2) Wrap the electric heat around the water pipe, and wrap it with insulation material on the outside.

3) Don't close the tap tightly, let it drip slightly, as long as the water flows, it will not freeze.

I haven't been to the north and don't know how to do it. In my imagination, in addition to heat preservation, there is also a heating function. Because in extremely cold weather, the insulation will also lose its effect.

Once frozen, there is no way to thaw for at least three months. If there is a heating device in the pipe, it can be heated and thawed at a critical time.

1. Do not twist the frozen water pipe, do not use pliers and other tools to start hard, and do not use fire or boiling water to pour it directly, otherwise it is easy to damage the faucet and cause the pipe or water meter to burst. The correct way to do this is to wrap the faucet in a towel and pour warm water along the faucet to thaw it down the pipe, or use a hair dryer to blow the faucet.

2. The freezing of indoor pipes can be solved by increasing room temperature.

Precautions for water pipe freezing:

1. Protect the billing water meter, remove the water in the water meter well, and wrap the water meter in the meter well and the opening cavity of the front and rear water pipes with thermal insulation materials, exposing the dial for easy inspection.

2. Close the doors and windows at night to ensure that the indoor temperature is above 0. In case of severe cold weather (below -3), in order to keep the faucet from freezing, the most effective way is to unscrew the faucet slightly after using the water, keep the drip or line flow state, and ensure the flow of tap water in the water pipe.

Causes of freezing and cracking: From a physical point of view, the cold winter is as low as the temperature is low, at this time, the water will slag due to the solidification phenomenon and let the ice, the mass before and after solidification remains unchanged, and the density of ice is smaller than that of water, so the volume will become larger after freezing, so the water pipe can be frozen and cracked.

In winter, the practice of avoiding the rupture of the water pipe can be insulated by exposing the water pipe and faucet on the ground, such as using a wooden square bucket to cover the faucet, filling it with sawdust, exposing the faucet, and adding a wooden cover can not freeze, it is best to add a main valve at the starting point of the exposed water pipe, once the faucet is frozen, the main valve can be closed, or the main valve can be closed when going out for a long time to prevent water leakage when the faucet is frozen.

In winter, when the temperature is low, the water in the outdoor water pipe is easy to freeze, and after freezing, the volume becomes larger, causing the water pipe to freeze and crack.

In view of the above reasons, if you want to prevent the water pipe from freezing and cracking, you must take certain insulation measures. The general insulation measure is to wrap a thick sponge with tape on the surface of the water pipe, and some places will adopt the insulation method of sawdust + sponge.

Hope this answer solves your problem!
