Nevergreen Pools provides pool pump repair in Gilbert, covering shaft seal leaks, worn bearings, motors that won't start, pumps that won't hold prime, cracked pump housings, clogged impellers, and air leaks at the strainer lid. Pump failures here tend to show up in late spring, when the pump has been running long filtration hours after months of light winter use and a weak seal or a tired capacitor finally gives out under the load.

Call us if the pump hums but the shaft won't turn, if it clicks and trips off without starting, if you see water pooling under the pump housing near the shaft, if the pump loses prime and needs to be primed by hand every time it starts, if the motor is noticeably louder than it used to be, if the pump runs but flow to the returns has dropped off, or if the pump cycles on and off on its own without you touching the timer or automation.

We serve Gilbert in partnership with Beyond Pool Cleaning, a pool service company based nearby. Call to get a technician scheduled, or book your first visit online.

How We Diagnose and Fix the Pump

We start at the equipment pad with the pump running, if it will run at all. A grinding or howling noise with the shaft turning normally points to worn bearings in the motor, which usually means the motor gets replaced rather than repaired, since bearings aren't a serviceable part on most residential motors. A motor that hums but won't spin, or that clicks and shuts off on its own, is almost always a bad start capacitor, and that's a straightforward swap once we've confirmed voltage is reaching the motor.

If the pump won't hold prime, we check the obvious points first: the strainer basket for cracks, the lid o-ring for a dry or flattened seal that's pulling in air, and the pipe fittings on the suction side for a loose union or a hairline crack that draws air without ever leaking water on the ground. A pump that primes fine but then loses suction over the run points to a suction-side leak rather than the pump itself. Water actually leaking from the pump body, right where the wet end meets the motor, means the shaft seal has failed and needs to be replaced or the pump needs to come off the pad for a rebuild.

Impeller clogs show up as a pump that runs at full speed but delivers weak flow to the pool. We pull the diffuser and impeller, clear whatever is jammed in there, usually pebbles, debris, or scale buildup, and check the impeller for cracks before putting it back together. A cracked pump housing, from age or from being over-tightened at some point, gets replaced rather than patched, since a patched housing under constant pressure will fail again.

• Test power and capacitor before condemning a motor that won't start
• Check the lid o-ring and strainer basket for air leaks before assuming a bad seal
• Inspect suction-side unions and fittings for hairline cracks
• Pull the diffuser and impeller to clear clogs and check for cracks
• Replace the shaft seal if water is leaking from the pump body itself
• Confirm flow and pressure readings after any repair before closing out the pad

Motor Swap vs Full Pump Replacement

If the pump housing, impeller, and diffuser are still in good shape and only the motor has failed, a motor swap is the right call, and it costs a fraction of a new pump. We match horsepower and frame size so it bolts up to the existing wet end without adapting anything. If the motor is single-speed and the housing is older, this is also the point where switching to a variable-speed motor on the same wet end makes sense, since it runs quieter and costs less to operate without replacing the whole pump. Full replacement makes more sense once the housing is cracked, the wet end is worn from years of sand and debris passing through it, or the pump is old enough that a second failure is likely within a year or two of fixing the first one.
