Installed a 52gal WellSaver Pressure tank... all seems to be working fine however I am concerned that the tank is not storing enough water. You see the unit can be moved side to side (or wobbled) very easily once the small shim underneath (uneven floor) is removed. The tank can be wobbled almost too easily and my guess is there is only a couple of gallons inside the tank. Pressure is decent however I think the well pump is coming on too early. I did set the internal pressure to 28# before bringing in the water. Any ideas? Thanks!
