Loss of water pressure w/new pressure tank
Hello everyone,
I have a question involving my plumbing. I was having terrible water pressure and I checked the pressure at the pump itself and it was great. Went to the pressure tank and it was trickling. Shut down power to pump and drained system - checked air pressure and it was not registering. Tried to refill tank and it would not hold pressure. Decided to replace tank (old one was 20 gal) and since I am using an awful lot of water (dishwasher/washing machine/family of 5 - so 2 to 3 showers a day, etc. etc.) I wanted to go with a larger tank (86 gal). Installed with no problem (moderate experience.) and left the factory pre-charge at 30 psi. Opened all faucets, turn on water pump, waited for all air to be released and closed faucets. Waited 1 hr. to let tank fill. And now I can not get any more than 15 to 17 psi (according to gauge near tank). And when I shut power down and try to drain system, I am only getting about 2 to 5 gal from the system only. Please help
