Downstairs in the bathroom leaking corridor, repeated inspections have not found leakage, and there

It is estimated that the water pipe is leaking, it is recommended that you find a master to replace all the water outlets with plugs, and then use a 10 kg pressure gauge to apply pressure, so the sensitivity will be very high, and the error of the large pressure gauge will be very large. Half an hour later, the leakage means that it is a problem with the water pipe, and if it does not leak, it is a problem with the angle valve. To check the specific leakage point, first separate the hot and cold water pipes and apply pressure to determine which water pipe.

Then refer to the leaking water stains and the direction of the pipeline to determine the scope of brick knocking, this part can only depend on the experience of the master you are looking for.

You do an experiment, from where the water inlet pipe is added to the water, and when you open the water valve, you can see the traces from where it comes out, and you can roughly determine what the problem is, or it may be a problem with the quality of the water pipe, there are capillaries, there are leaks, you can find a property in the house you bought, and this should be the responsibility of the developer.
