We suddenly have lost water pressure in our house. We have 60 psi of water before the water hits our pressure tank. The pressure gauge between the pressure tank and the house shows 60 psi... But the pressure tank doesn't seem to be filling with any water. We replaced the tank with a 50 gal tank pre charged to 45 psi. We are still experiencing the same problem. The pump seems to be cycling correctly. Could our softener system be part of the problem? Any help or suggestions would be greatly appreciated!
