We have an A.O. Smith Aqua-Aid Model V60 Water pump and storage tank. The pressure fluctuates between 35 and 58 psi when water is running. I believe this to be normal.
My issue is after a period of non-use and water is run the tank will make a 'bang/clunk' sound when the pump turns on. It doesn't do it ever time and we notice it more in the morning, but it does occur throughout the day. I know the noise does not come from pipes, it seems to be localized at the tank. My question is, what is causing the banging/clunking noise and how can I correct it? It may say AOSmith but I found your pump to be manufactured by Gould,(see image). For openers let's check the bladder tank. There are several ways to check your tank.

It has a air valve on top like a valve on a tire. Push it in, you should not get any water out of that valve at all.
Another way is to tap the tank from the bottom up. You will hear a 'clunk' on the bottom filled with water, however you should hear a 'clang' near the top filled with air. If you have water up to the top the bladder has ruptured and the tank must be replaced. To set the air pressure in a bladder tank, look at the cut-in pressure on your pressure switch. Now drain the line down with the pump off. When there is no more water coming out of the hose bib that you drained the system down with set the pressure in t6he bladder tank at 2 lbs.
Below the cut-in pressure. Check it with a tire gage. If your pressure control is set to come on at 20 PSI and go off at 40 PSI then your gage should read 18 PSI. Hope this helps and thank you for rating my reply.
