I noticed the water pressure was low, so I went to the basement and took a look. I pulled the cover off the regulator and noticed that the contacts were always closed indicating that the pump was on. The pressure guage wouldnt get above 30 psi. The regulator is the 40/60 type. The pressure tank air was at 36 psi. When a faucet is opened, we get a couple minutes of OK pressure then pressure just drops to zero, which we can see at the guage. Waiting a few minutes will get us back to 30 psi. What can I do?
