I have an AO Smith Aqua Air Water system tank (model no. 60). I purchased this home last year, and have no experience with well pumps. The well pump is only for the outside faucets (inside faucets are city water). This is a very nice feature, but I can't get water to work. I constantly have no pressure in the tank. I manually turn on the tank and most of the time I can get it to build up some water pressure, but after about 15 seconds the water stops and I have no pressure again. I tried putting air in through the nipple on top of the tank, but got nowhere with that (my air pump read 20psi, but it never moved all the while I was putting air in). I know they are expensive to fix and was hoping for some advice/direction. Thanks!!!!
