Why didn't the water pipe burst when it was cold, but it burst when it was warm?

When it is cold, it reaches the critical point. When it suddenly became hot, the frozen pipe burst.

Winter is during the Chinese New Year, so some owners may go back to their hometown, and the house will be vacant at this time. At this time, it is best to close the water valve and drain the water in the water pipe to prevent the water in the water pipe from freezing. If you find that the water pipe is frozen, don't thaw it with hot water in a hurry, because it is easier to burst.

The correct way is to pour it slowly with warm water, and then open the water valve to drain it slowly, because the slowly flowing water can bring the underground warm water to the water pipe on the ground, so that the frozen water in the pipe will slowly melt and the water pipe will not burst.

Matters needing attention in expanding data

Carefully choose the material of the water pipe.

Sometimes the burst of water pipes has a great relationship with the quality of water pipes. There are many materials of water pipes in the market, including PPR pipes, aluminum-plastic pipes, copper pipes, stainless steel pipes and so on. We need to choose products with moderate price and stable performance, and PPR tube is still the ideal choice.

It seems that walking on the top of a water pipe wastes a lot of pipes than walking on the ground, but it still has great benefits, because if the water pipe bursts due to aging or low temperature, it will leak, but if it is "walking on the ground" at this time, it will be difficult to find, and maintenance will be very troublesome. If it is walking on it, it will be easy to find.
