Shallow well pump - HELP !

I just put in a new 1/2 hp shallow well pump. The pump kicks on & off & back on quickly before running. It seems as though the pressure is dropping steadly to about 30lbs then very quickly drops to 20lb & the pump kicks on. The pressure jumps back to 40 & the pump shuts off then quickly back to 20 & back on where it runs fine. Anyone have any ideas on why it would do this ?

Your pressure tank is water logged. The type of tank you have will determine the solution. You may need to replace the tank.

I have a WellSaver 20 Gallon Vertical Pressure Tank. I just installed that the same time I replaced the pump.

Since I have never heard of a well saver tank. Is it a bladder tank or a galvanized pneumatic tank? Or does it have more than one plumbing fitting on it? And does it have a little schrader valve that you can add air to?

If it's a bladder tank, you may have the pressure in the tank set too high and sometimes the bladder will be stuck to the bottom of the tank. Although I think all the manufacturers have gotten past that problem.

Sorry about that. It's a bladder tank. It only has one plumbing fitting. It does have a valve to add air. It came pre-pressurized. I belive at 38psi.

Ok, that explains it. YOu have too much air in the tank for your switch setting. If you have a 20/40 switch, you need to turn off the pump, open a faucet until the water stops flowing. Let the air pressure in the tank down to 18 lbs. Turn the pump back on. Now it will function properly.
