1hp Sub pump 230v (15GPM) with an 82 gallon Bladder tank Square "D" Switch and a small inline filter. This is a shallow well. The pump is down 30ft with static at 7 so it is in about 23 foot of water.I have setup the tank 2lbs below the cutin pressure 40 and cutout is 60. The problem is the pumptec is shutting down the pump after 3 or 4 lbs of pressure to the system. I read in this forum that a filter should not be installed before the Tank. This small inline filter is installed right after the pump outlet. Could this be causing my problem?
