What if the main water pipe leaks and the property refuses to repair it?

You can ask the property to come forward to solve it. If it is not resolved, you can consider suing. Waterproof warranty for 5 years and pipeline for 2 years. During the warranty period, the developer is not responsible. If not handled, you can complain to the local quality supervision department. They specialize in this matter and can't go to court again.

The water pipe is a water supply pipe. Modern decoration water pipes are built by burying walls. There are three types of water pipes. The first category is metal pipes, such as hot-dip cast iron pipes lined with plastic, copper pipes and stainless steel pipes. The second category is plastic-coated metal pipes, such as plastic-coated steel pipes and aluminum-plastic composite pipes. The third category is plastic pipes, such as PB and PP-R.
