Pool Pump Making Noise in San Diego
Screeching, grinding, or rattling from the pump almost always traces to the bearings, the impeller, or cavitation. Below: the likely causes, what you can safely check, the typical fix cost, and a link to local help in your city.
Likely causes
- 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 first
- 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
