I have a 3/4 hp utilitech jet pump. I keep losing my prime and have a very difficult time getting it reprimed.Have checked all clamps and they are tight. Any suggestions?

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.



Hope this helps?

Put a vacuum gauge on the suction, see if it goes real low after pumping a couple of gallons. If so, your point may be stopped up. A 1/2 hp pump should pump 40/50 psi, fill a 5 gal bucket in a minute or so.

See if the check valve on the intake pipe is operating.

for the pump to lose pressure there has to be a leak somewhere please check and make sure you have a one way valve on the bottom of your jet pump that will not allow the water to run back into the well

An electrical fault is tripping off the power relay. Check the current draw of the pump motor.

Try replacing first the capacitor. If it will not solve your problem, check the integrity of the motor winding insulation by doing a line to body resistance measurement. If it is okay, replace the motor bearings.

Hi mid_age_elf
Your problem is that your "water bound"...
Your water tank must have a cushion of air for the pressure switch to work properly.
Turn off your pump and drain about 1/3 of the water from your tank.
Once you have an "air cushion" the pump and switch will work properly.
You can also add air pressure using an air compressor and an air valve installed on the top of your water tank or maybe on the side or bottom of the tank.
You would put air into the tank until about 1/3 of the water is gone replaced with the air.
Once that is complete your problem will be solved.
Please take time to rate me

The water and therefore the pressure has to be going somewhere. If you are sure that there are no leaks in the house or outside, then the water is going back into the well. There is a check valve either in the suction line of the pump between the top of the well and the pump or down in the well.
If this check valve fails, it allows water to go the wrong way and back to the well. The result is that you lose pressure.
Secondly, you have to be sure that there are no air leaks between the top of the well and the inlet to the check valve. Leaks in that piping will make repriming difficult.
Write back with more and I'll try to help more.

sounds like the pump has lost its prime there for it will not pick up the water it kinda like a fuel pump on a vehicle so u should try filling pump were its suction is an reprime it manually until and start it but dont run all the water out or it will lose prime again its lot easier if i was doing it my self than telling someone hw but just try wat im telling u and u should b able to get it back on track and running like new once again

Check valve might be bad.
