Is the water meter nut ticking? Is the water supply company in charge?

It doesn't matter. The water meter nut is dripping water, which belongs to the leakage of the front pipeline. It is the responsibility of the property company and has nothing to do with the water company. Water meter is an instrument for measuring water flow, mostly the cumulative flow of water, which is divided into two types: volumetric water meter and speed water meter. It originated in Britain and has a history of nearly 200 years.
