I have been having trouble with my pressure switch "chattering" recently. I have just had a new pressure tank and submersible pump installed and the switch was adjusted to cut in at around 40 psi and cut out at about 60 psi. It does great at the cut out, but as the pressur drops to the cut in point, the switch suddenly starts cutting in and out, very rapidly, for several seconds. Then it will finally stay switched on and the pump drives the pressure up to 60, where it shuts off normally. What's up?! I know this can't be good for the pump. Is this something that can be adjusted, or should I get a new switch?

Was is the pressure in the pressure tank (if it is a bladder type). If non-bladder was the tank pressurized or has an air control valve.

The pressure in the tank should be about 3 psi higher or lower than the cut in pressure. I never remember which.

But a google will find it.

Also you can have this problem if the pressure switch is mount near the pump and fair from the tank.
