Someone replied to his question. I turned the pump off, and drained the tank, I only had 15lbs of pressure. I believe it should have 2lbs less than the cut-on, so I put 30lbs off pressure in.
Every faucet seems to have good pressure but the tub.
It is so low that I can't even get the shower to stay on. I have a button to pull up on the spout and it should, by pressure stay up and the shower should go on instead. Any suggestions please.
