About a year ago we had our buried pressure bladder rupture. we have not dug it up. We just added a new pressure bladder in the basement so it is easily accessible. That seemed to fix the problem with the pump switch turning on and off quickly. The problem we are having now is the pressure bounces continually. It doesn't build pressure evenly. We checked the pressure bladder, and it still had 25 psi and no water, so we know that is not ruptured. We re-pressurized that, and the problem is still there. When eliminating the bladder from the system, the pressure builds evenly to 55 PSI, but there is no pressure in the system, and the pump continually runs on and off on and off. but it does not bounce when it starts and stops. I believe I have eliminated the pressure bladder as the problem, but the water softener is also in that circuit, so we can't eliminate it altogether. I believe that it is either contamination in the water softener, not allowing it to flow evenly, or sediment in the lines that is allowing the pressure to bleed through slowly. Also pressure stays in the system for days on end. There does not seem to be any leaks anywhere. No leaky faucets, or running toilets. PLEASE help. we have been trying to figure this one out for a week. We also can't get any soft water. I cleaned out the venturi valve in the water softener, there is no salt bridge, and all the valves are on. This is getting very frustrating!
