 well pump/tank pressure issue
Author: headusher (NC)

The other day we noticed the water pressure increased quite a bit. Called a plumber we know and he said the tank pressure was too high (45-55 setting) and adjusted it for a 30-50 psi system. Can't explain why the pressure settings changed. This worked fine until last night when the water pressure was low and the pump started cycling off/on every few seconds when water was being used. Checked the tank pressure again and it was back up around 45lbs. When I drained the tank to check the pressure reading I only got about a cup of water to drain. Set the tank pressure at 28lbs and turned the system back on. Worked fine for about 7 hours then the pumps started cycling on/off again. Again the tank pressure was in the high 30s. Reset the pressure again for 28lbs ands is working fine again.

Any suggestions on what's going on? Tank appears to be ok, no water coming out of the air valve, tapping side indicates it's not water logged. Pump appears to be running fine. Waiting for the plumber to get back to me.

If it only took a "cup of water" to drain the tank, it IS water logged, and there is almost ZERO air in the reservoir. You have to drain the tank, leave a faucet open, and THEN pressurize the tank with air to the proper amount.

Does this imply that I need a new tank. It just happened again after a shower. The pressure was up over 10 lbs and only a small amount of water drained. I reset the pressure in the tank and everything appears normal again...for now.

To lower the pressure I release the air from the tanks air valve. What is this air that I release?? I ask this because my understanding of a water logged tank means there is no air in it.

It means that there is very little air in it. The tank is mostly full of water, when it should be about half and half. you CANNOT "reset" the pressure unless all the water pressure is out of the tank and a faucet is opened so the new air can push water out of the tank.

It was a bad bladder. Freaky symptoms had us stumped for a while. Thanks for everyone's input.
