Can't get irrigation pump to pump water.

Have a 1 hp. Utilitech irrigation pump, about 7 years old. Used to pump several GPM. Now it's just a trickle. Check valve is working properly. Tested capacitor, it was bad and replaced it. Only thing I can think of is the impeller. Any ideas?

Pump turning slow because of a bad bearing, stuck starter switch, bad shaft seal, or bad motor winding will cause loss of flow.
ANY leak in the suction including the shaft seal will cause flow loss.
Plugged impeller will cause loss of flow.
Plugged discharge (inside the case) will cause loss of flow.

Good luck

SOURCE: I have a Whirlpool GD5SHAXLQ02

I wonder if there is a blockage or an air lock in the water feed. Can you disconnect the feed and get someone to blow down the end of the tube connected to the fridge as you press the switch?While disconnected also make sure that there is a flowing supply out of the feed pipe At least you'll have some fun and you might get nearer finding the fault! Isnt it obvious whether the inlet valve is opening, surely you can hear it working?
let us know how you get on
Is that worth a vote?

SOURCE: I'm looking for a replacement impeller for a 1 1/2

Hi, If you have removed the old impeller, the part number will be in the center. If wear has obliterated the part number, then the replacement impeller will be either spx1610-c for medium head or spx1611-c for a high head. Later models of super pumps will have a 2600 series of numbers for the upgraded drive train. However, the 1600 series drive train parts are still available.

SOURCE: Our centurion pool pump motor Model B128 replaced less than 1 year ago. Pool company has to replace the impeller twice. Is this common? I believe the pool co sold and installed a used pump instead

Broken impellers generally are not caused by the pump's motor. Impellers usually fail due to back pressure from the filter when the pump shuts off. Air in the filter is compressed while the motor runs, on your pump 12-15 psi. or a bit higher.

When the motor shuts off that compressed air forces water back to the pump, sometimes with enough force to loosen (or completely throw off) the impeller. If the impeller is loose when the pump starts up again it will instantly re-thread the impeller and strip out the threads.

Check to see if you have a suction leak. After the pump has turned on, bleed the air out from the air relief valve on top of the filter. After the pump has run for a while open the air relief valve and see if air comes out. There should be no air, or just a little.

I have seen this back pressure strong enough to blow the skimmer basket up onto the deck.

What make and model of pump and filter do you have?

How do I figure out water pressure?

There should be a check on the suction side, and a gauge on the pressure side. Pressure comes from flow being slowed down or stopped. If the outlet is full open, no real pressure will be seen.

Short in well

the best would be to rewire and check if its running in a bucket of water, if all is ok then seal it with a epoxy resin cast
