I am so confused. I had good pressure on my water well. It has a submersible 1/2 HP pump and a pressure tank. I replaced the check valve and everything was fine. But the pressure gauge was cracked and not working correctly so I replaced it a couple days ago. Now the well won't pump up past 20 pounds. it was getting up to 40, now only 20 with main shut off. How do I add air pressure and how much pressure should I have? Plus I think I have other problems as well, but I have to start somewhere.
