SOURCE: onga pool pump running but not drawing water from pool

Take out the pump pot basket and stick your finger in the hole towards the motor (make sure the motor won't kick on!!). What you should feel is the impeller. It has five grooves in the face of it and each one needs to be cleaned of foilage and debris. With every hole clogged in the impeller you lose 20% of your motors effeciency. With whisperflow brand the pump pot basket is poorly designed where debris like pine needles go straight through.

SOURCE: we have a onga pump model 445 that we use to draw

The pump is equipped with a pressure switch.It is a rectangular thing on the discharge side of the pump. If you open its cover, you will see 2 springs with turning bolt on top. The larger spring controls the operating pressure (pressure where you want the pump to stop), and the other one is for the pressure differential (the difference between the pressure you want to stop and the pressure you want to make the pump run again). Usually, the springs are graduated. just turn the adjusting screws to the desired operating pressure and desired differential. For example you want to stop your pump at 40 psi and run it again at 30 psi. Adjust the larger spring to 40 and the smaller one to 10.

SOURCE: onga jsp 130 leaks

It is leaking due to a defective mechanical seal. It needs to be replaced. To replace it, is to take the pumpcase
off by taking off the bolts that hold it. Then, take the impeller off to take the mechanical seal behind it. Put the replacement in, and reassemble the pump. Just get in touch with us by e-mail to get more assistance.

SOURCE: how to adjust pressure switch onga pump.

your pump should have a 20lb seperation ie. pump turns on at 20lb and off at 40lb or on at 50lb off at 70lb. under the cover of the switch theres two screws with springs under them.dont mess with the small one.the large one if you screw it down (right) will increase the pressure while maintaining the 20lb separation. one thing to keep in mind its fine to adjust the pressure BUT at the same time the air pressure in the tank needs to be adjusted to two lbs below the cut in pressure of the pump.

Onga JJ 600 household pump with pressure cylinder. Pump cuts out at pressure but won't cut in until water flow has stopped. Pump approx 5 yrs old and no previous problems.


It sounds like a pressure switch problem. Check that your tank pressure is at two psi below your cut-in pressure. If it is correct, then I suggest replacing the press switch.

No pressure for onga pump


check for water supply to the pump
If it is a bore pump then check for enough water in the bore, injection pressure to lift the water. It may be necessary to control the output from the pump to maintain the injection pressure. ( put a tap on the outlet side and turn partially off)
check for sucking air at pipe fittings

My electric onga water pump which pumps water from my watertank to the house will not turn off. I have looked for a leak but cannot find one.


What is the model of the pump? What type of control does it have - pressure switch, electronic controller or what?

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.

Water will not shoot out....took the hose off and it still doesn't work


If this model has a quick disconnect coupling for the pressure hose opposite of the sprayer wand at the pump, remove with a wrench. Hook up the water hose, turn on he water , but don't start the engine. If it has a clog this will flush out the clog. Replace the coupler and hose, turn on the water first before starting the engine. If the pump builds pressure it will make the motor bog down slightly. If there's no change in the sound of the engine with water turned on, the pump will be damaged. If the motor bogs off and on and water sprays on and off, means there is an air leak in the pump. If the pump does not work at all with the water turned on, the pump will be burned up. Please don't take this in offense; but I've seen many power washer pumps damaged because the water was not turned on before starting the engine. Try these few steps and let me know if you get any pressure at all, if so it's probably an air leak. Good luck!

I have an onga model 445 pump wont work on a generator


You can try running a heavier Gage or shorter cord to the genarator. If that's been done try useing a power suppley box commeing from your gen. not a surge protector this will have battries inside it, doing this will cutt down on electrical resistance. If those don't work you will need a bigger gen. The problem is the amprage is to low, one more thing, look in to a inline a/c compasitor
