Hello, I have a well pump that has started short cycling. I have a Flotec 42 gallon pressure tank that is three years old. I have removed it to check for it being waterlogged and does not seem to be. I have checked the tank pre charge and have it set to 2 psi less than the cut in pressure. Checked it several times since and it always remains constant. I have replaced the pressure switch and it still short cycles. BTW I have a 2 drop jet pump. I am guessing the well is about 90'. The pressure gauge on the pump never drops unless a faucet is opened and doesn't seem to loose prime- by that I mean the water supply is always constant and immediate and never spurts. I have played around with the pressure switch to get it to not short cycle as much, but if the shower is used, the pump will never shut off unless water usage is halted. My guess is my problem is down in the well, i.e. the foot valve. Am I on the right track? Any help would be greatly appreciated.
