This usually indicates an air leak in the plumbing. it will **** air because it is easier than water if there is a leak in the plumbing.
good luck David

    How would I find the leak?

  • David Lowry Apr 06, 2013

    The pump is not always the problem. Usually you are drawing air and it will not pull the water to the pump. If it is for an above ground pool, it will not pull water very far at all. If it is for an inground pool, you should check all air leaks before you check anything on the pump. If you are leaking water at the pump, then check the shaft seal.

How many impeller fit on the pump


Impellers, vary. You can't put any impeller on a motor! Things to take into consideration for proper water movement / hydraulics, is the different parts of the volute: where the tide housed. You have the:
  • Impeller
  • Diffuser
  • Wear Ring
  • Shaft Seal
  • Seal Plate
The impeller also had to match the HP! If impeller is oversized, the motor will be over worked! If impeller is under sized, then the motor will work effortlessly, but is a waste, because it should at least be at capacity. Even if within the same manufacturer, impellers vary widely. So, find the correct impeller and use it.

The motor and filter seem to be ok, but can't get it to prime. Everything is working,just very little water pumping into filter.


It sounds like you have a suction leak or a clogged impeller. A quick way to check the impeller is to fill the pump pot (where the basket is) with water, then start the pump with the lid OFF. The water should be sucked down into the pump immediately. Turn the pump off. If it took more than about half a second for the water to disappear you need to open the pump and clear the debris from the impeller.
Otherwise any leak from the skimmer to the pump will cause the problem. Make sure your pump lid o-ring is lubricated.

My2 hp max e pro pump runs but barely moves any water


Have you opened up the wet end? If you have pine trees near you, it is probably a blocked impeller and needs to be cleaned. If this is not the case, is the pump basket full of water or air?
If it is full of water, it is either the impeller, or the motor bearing.

if it is full of air, it is an o-ring or shaft seal. more likely the shaft seal. Always check the impeller first.

How to disassemble a magnum 1500 - to change the bearing seal.


On the big lock ring there is a small clip that you pull out away from the ring then turn out of the way. It is just a peg to stop the ring from turning, with that done from the back of the pump loosten the ring in a counter clockwise direction. With the ring clear start the pump for just a second a couple of times till the water pressure pops the pump in two. Once that is done I beleve it has five screws holding the difuser on, pull that and on most models their is a center screw on the impeller. This screw is a left hand thread so turn it clockwise to loosten it. Then insert something flat and strong in a vain of the impeller on the left side and give it a sharp hit to start the impeller spinning off. If need be spin the rest of the way off and your at the seal. Rember when putting this back together Hand tight only on the impeller and use a teflon or silicone base lube not petroleium jelly.

This is a sign of a faulty drain pump impeller. the drive shaft that is connected to the impeller is stripping the impeller. you will eventually need to replace the entire pump soon.

2 hp vertical sta-rite well pump


Did you prime the pump? To prime: Before turning pump on, unscrew plug cap from top of pump (usually on pump impeller housing,) and with a pitcher or garden hose, fill pump full of water, and replace plug. Then turn pump on and see if problem is solved. If leaking: Are all fittings tight, O-rings and seals new, and is there any pipe thread tape on all threads w/o seals?

Leak off pump housing


Sidewinder, sounds like it's leaking from the pump gasket or the water seal assy on the impeller. Check the locking ring to the pump housing and see if you can increse the pressure to the tub. Also check the tightness of the motor fan assy. to the impeller assy. tighten if necessary. Pump gasket part number is 912529. Impeller seal part number is 903494. Catriver..post back.
