Pool Pump Making Noise in Coronado, CA
When a Coronado pool has a loud or grinding pool pump, the fix is usually straightforward once the cause is found. Screeching, grinding, or rattling from the pump almost always traces to the bearings, the impeller, or cavitation. Because Coronado pools contend with corrosive year-round salt air on some of the oldest original plaster in the county, a technician here checks a slightly different list than one at the coast would. Call and we will connect you with a Coronado pool pro who finds the real cause, not a guess.
Likely causes in Coronado
- Worn motor bearings (a high-pitched screech that gets worse over time)
- Cavitation from a restricted or undersized suction line
- Debris caught in the impeller (rattling or grinding)
- Loose mounting or a vibrating equipment pad
- Low water level pulling air into the pump
What to check before you call
- Check the water level; low water causes air noise
- Clear the pump and skimmer baskets
- Note the sound: a screech points to bearings, a rattle to debris
- Feel for excess vibration at the mount
