How to remedy the collapse of the kitchen floor due to a leaking water pipe?

Because the building can only be used after the acceptance of the relevant departments, the builder and the construction department are responsible!

If there is standing water on the ground, it is likely that there is a leak in the underground water pipe, and the water supply pipe that leads from the outside to the interior is mostly buried underground, so it is very likely that there is a leak somewhere in the pipe between the outdoor and the indoor kitchen.

If you are in the ground, you can only dig it up to make up for it if you want to solve it completely.

It shouldn't be that your house is leaking, if your house is leaking, there will be traces of water or water intrusion on the roof and walls of his house, not that there is water on the ground of his house. First of all, see if his house is geothermal, and then see if there is a leak in the water pipe under the vegetable washing basin.

The aging of the tube must be replaced. To do leak-proof is hello and I'm good. If you cheat. I don't want to do it. Neighborhood relations are not good. Things are complicated, and money has to be paid.
