Community Hall water pressure
The local community hall water is fed from a well the another building and then to the main community hall. The water pressure in the main hall is low. I looked at the system in the main building and see a pressure tank that reads about 30 PSI, which I believe is low. No pressure switch at this ocation, only a feed from the first building. .... The pressure tank in the main building has an air valve on it, ... should more air be pumped into this unit? Any other advice, opinions, suggestions on how to increase water pressure in the main hall?
