The water pipe leaked behind the water meter in the building before entering the house.

I don't know the year of the building where you live now, but from 2002 to 2003, the water supply pipe of the family building has been designed to use PPR pipes, which means that there are irresistible natural factors besides man-made damage or external force damage to the ground settlement and deformation surface. If it's broken now, it's easy to find the reason.

If you are not staying for a long time, you can complain to the local construction quality supervision department within a few months, or you can complain to the local housing and construction bureau and the engineering department of the real estate administration.
