What Are the Signs My Pool Pump Needs Repair?
Here are the top 5 signs your swimming pool pump needs repair:
Unusual noises — Grinding, screeching, or rattling sounds often indicate worn bearings, a failing motor, or debris caught in the impeller. A healthy pump runs with a consistent, low hum.
Weak or no water flow — If your water isn't circulating properly, the pump may have a clogged impeller, a failing motor, or an air leak in the suction line. Poor flow also strains your filter and affects water quality.
Pump is losing prime / sucking air — If the pump basket frequently runs dry or you see air bubbles returning through the return jets, there's likely an air leak somewhere in the suction side — often at the lid O-ring, unions, or valves.
Motor overheating or shutting off — A pump that trips its thermal overload protector and shuts itself off is struggling. This can be caused by a failing capacitor, a clogged impeller restricting flow, poor ventilation around the motor, or the motor simply nearing the end of its life.
Leaking water around the pump — Puddles beneath the pump often point to a worn shaft seal (the most common culprit), cracked pump housing, or failing O-rings. Even a small leak will worsen quickly and can damage the motor if water reaches it.
General tip: Catching these issues early is key — a pump repair is almost always cheaper than a full motor or pump replacement. If you notice any combination of these signs, it's worth having a pool technician inspect it sooner rather than later.
