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

Have an Onga JJ400 jet water pump several years old, pump is working but delivering poor water flow

Is the pump building pressure and shutting off? If the pump keeps running but not building pressure than there is most likely a problem with the well (low volume). Also check for a water logged bladder tank.

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.

I got 1 year old flotec 3/4 hp pump and it take

I have had the same problem there are a few things that can cause it to take longer to shut off, if you are running a sand point well that's usually a sign that the sand point is clogging up,if you have a sistern or a dug well check the screen on the end of the suction pipe,another possible cause is the water level has dropped low enough the pump is having to work harder to pull the water up, you should also check your pressure tank and the points for the pump if the points are sticking the pump will keep running till it builds enough pressure to trip them.Check for leaks in the suction line, if it is sucking air that would cause it to run longer to.I hope these suggestions will help fix the problem. Have a great weekend

Pump will not come up to pressure and turn off!

With no leaks in line and assuming the jet is not embedded in debris at bottom of well, try priming the pump again and getting all the air out.

New 1/2 hp jet pump with tank not working

Your hose size is to small. Use a 2in black plastic line out to the lake. Inspect your foot valve, and
take your pump apart to see if you may have a pebble stuck in it, and remove the inner workings
and clean. Contaminates build up inside and need to be flushed out. Remember to replace the
gasket. Tighten all your hose clamps. Once your ready to start, spray shaving cream on your
fittings to see if your sucking air. I've been through it all and my pump works fine.
