Our problem started when the well pump wouldn't build up enough pressure to cutoff. Air in the tank bladder is correct. Prior to this we had adjusted the pressure switch to cut on at 25 and off at 38. It now won't build up pressure to cut off. The pressure reads around 20. We pulled the lines and cleaned the foot valve and venturi jet at the bottom of the water lines. We took the foot valve assembly apart and cleaned all sediment out. We replace the pipes in the well. We checked the depth of the well and water depth. All is good. Plenty of water and room at the bottom of the well so we aren't at the bottom. The foot valve is 18 feet below the water lever with a 15 foot reserve below. Flushed the connection to the pressure gauge and pipe fittings where the pipes join the pump. Primed the pump, we primed the impeller to eliminate any air pockets in the pump. We also opened all the faucets in the house to ensure no air pockets in the house pipes.
We started to pull the pipes off the pump again. When we started to pull the pipes we heard air escaping from the pipes so we think we don't have any air leaks in the pipes.
The whole system is only 8 years old (tank, pump, foot valve assembly etc). Well pump holds its prime. What is causing the pressure not to build up over 20?
