CANNOT GET NEW PUMP TO PRIME,OLD PUMP WAS WORKING FINE JUST LEAKING AROUND MOTOR/PUMP HOUSING,BEST WAY TO PRIME NEW PUMP IS MY QUESTION


A shallow well pump needs to be primed. On the bottom of the well above the sandpoint there should be a foot valve (check valve) installed.

On the top of the pump there is a fill cap. Fill the pump until it is filled to the top. I

Replace the fill cap and start the pump. If there is air remaining in the well attempt a second time.

If the pump can not be filled it would indicate that the check valve is not working\ or the water level in the well is low.

Can the pressure switch on the Utilitech 1hp convertible shallow well pump be changed from 20/40 to 30/50?


Yes, if the plumbing can handle the extra pressure. There should be a nut in the middle of a large spring inside the pressure switch. Turn that nut clockwise to increase the pressure. You may need to run some water to keep the pump cycling while you do this.

Shallow water pump keeps stopping


new pump --not big enough for the job
old pump --motor windings problem, faulty start run capacitor
I suspect that as the motor is 1/2 hp if will run good when there is a need for water but under pressure the pressure switch is set to high so the motor overloads and gets hot

1/3 hp shallow well jet pump (mastercraft brand). After power outage i have been having problems with pump. It will run continuously without building up enough pressure to cut out. It wil build up to about...


I don't think the power shortage had anything to do with the pump, I think it is the impeller or a gasket, or both. It is hard to say, a pump like that should **** dry and pull water right in.If you put your hand over the end of the pipe, it should make a mark like an octopus on your hand. I would take off the impeller, look for trouble, and replace 3 or 4 parts in there , you should have water. Hope this helps.

Pump stopped working while pumping


Yes, most motors are thermally protected. It is usually bi-metallic, and resets itself.
