How to dredge the underground water pipe when it is frozen?

The underground water pipe is frozen, and the dredging method is to restore it with hot water.

We can find a soft plastic pipe with a diameter of about one centimeter and insert it into the frozen water pipe. Next, prepare a pot of boiling water, cool it a little, rush into this pipe, and slowly insert the pipe into it until all the ice cubes melt.

Moreover, when pouring hot water, it can also be poured directly outside the pipeline, which can increase the internal temperature and achieve the effect of melting. However, this method costs more water and takes a little time to achieve dissolution.

If the indoor water pipes are buried underground, the indoor temperature can be increased and the water pipes can be naturally thawed, and the effect will be faster.

Anti-freezing method of water pipe

1. Heat preservation treatment of water meter: during decoration, not only the water pipe should be insulated, but also the water meter should be insulated, because many times there is no problem with the water pipe, but the water meter is burst by ice, which will bring inconvenience to domestic water.

Therefore, when decorating, it is necessary to do a heat preservation treatment for the water meter. Of course, some property and water supply companies will also pay attention to this problem and take the initiative to do heat preservation measures for the water meter, with the aim of preventing the water meter from freezing and cracking.

2. If there are no people living indoors, drain the tap water: every day in extremely cold weather, there will be newly installed and newly maintained new houses, and the renovated ones will be frozen. For example, the toilet in the bathroom, the shower in the bathroom, the gas water heater in the kitchen and so on. In cold weather, they didn't open and close the window in time, so they were frozen and cracked.

Therefore, if you haven't moved in after the renovation of the new house, or haven't lived at home for a long time for various reasons, then in winter, you should close the main water valve at home, then drain the water from the water pipe, and at the same time close the doors and windows in time to avoid unnecessary losses.
