A quiet pool system is a happy pool system. When you hear unusual sounds coming from your pump, filter, or heater, they’re often clues to underlying issues. Here’s how to decode common noises and decide when professional help is needed.
Grinding usually points to worn bearings in the pump motor. Rattling can be loose hardware or debris caught in the impeller. Both should be addressed immediately—running the pump in this condition accelerates damage and raises the risk of a complete motor seizure.
A belt-driven automation system or air in the suction line often produces this noise. Check that all unions are tight and the pump lid is sealed. If it persists, the motor’s internal fan or shaft may be misaligned, requiring a technician’s inspection.
Clicking sounds near the heater or filter valve often indicate thermostat or pressure switch cycling. Occasional clicks are normal, but rapid, repeated clicks mean a component is failing to engage properly. This intermittent operation can stress electrical components and shorten their life.
Air in the suction plumbing creates a gurgling sound at the pump basket. This usually means the pump lid seal is leaking or a pipe joint has slipped. If ignored, air-laden water causes cavitation, damaging impellers and seals.
Hissing near the heating unit may indicate high-pressure steam or gas escaping from a cracked heat exchanger or loose fitting. Turn off the heater immediately and call a professional—gas leaks are dangerous and require certified technicians.
Strange noises shouldn’t be ignored. Schedule a diagnostic today and we’ll pinpoint the source before it becomes a costly repair.
