Pool Pump Troubleshooting in Buckeye, AZ

It's Loud

Distinguish two sounds. A grinding or screaming that rises with the motor is bearings failing, and that is a motor issue — often a motor replacement rather than a whole new pump, which is a considerably smaller bill.

A rattling, gravelly sound like the pump is passing stones is cavitation: the pump is starving for water. That is not a broken pump, it is a restriction upstream, and fixing the restriction fixes the noise.

There's Water Under It

Where the water is coming from matters enormously. A drip from a union or the lid is usually a dried o-ring — cheap and quick. Water coming from between the motor and the pump body is the shaft seal, and that one needs attention promptly because the water is heading for the motor windings.

Drip at the lid

Lid o-ring dried out. Clean, lubricate or replace it.

Drip at a union

Union o-ring or a loose fitting. Straightforward.

Water between motor and pump

Shaft seal. Get it done before the motor is ruined.

Puddle with no obvious source

Worth a proper look — could be plumbing under the pad.

It Won't Hold Prime

The basket should fill with water and stay full. If it is half empty or full of swirling air, something on the suction side is drawing air in. Work through the possibilities in order — most of them you can check yourself in ten minutes.

• Water level too low, skimmer pulling air
• Pump lid not sealing — check and lubricate the o-ring
• Basket full of debris
• Cracked or loose union fitting
• Impeller clogged with leaves or pods

The Returns Are Weak

Weak flow with a quiet pump is nearly always the filter. Check the pressure gauge — if it is well above the clean reading, the filter is loaded and the pump is straining against it. If the pressure is low and the flow is weak, the restriction is before the pump instead, which points back at baskets, the impeller or an air leak.
