Look, you've answered the water meter. Please consult me. See if my house is leaking or something else?
Water meter is that kind of technology is relatively backward, the sensitivity is poorIn addition, the water meter is idling or reversing because of the flow of water caused by the change of water pressure in the pipeIn principle, the installation of the check valve will not cause problems in your home. The function of the check valve is to prevent the backflow of water in the pipe
If a check valve is installed and the water meter does not turn, then the water in the home pipe does not leak. The water meter idling is caused by the air in the pipe. After the check valve is installed, the water meter will still rotate if the inside pipe or facilities are leaking.
In fact, just someone gave you the answer, in order to know the leakage in the end, the simplest and most effective way is to measure water pressure, I suggest you put a little high water pressure, at least to 1.5 pressure. Water pressure just hit, is a bit of turning, 10 minutes less than the appearance will be stable, generally will turn a grid. If the water pressure of your house can be kept stable, it can be proved to be watertight. Otherwise, you know how to deal with it. Don't be fooled by the developers. Hope to help you.
