How to Fix / Troubleshooting
Safety first: Turn off power before inspecting the pump.
- Check for air: Bleed air from pump unions and ensure water level is adequate.

- Secure pump: Ensure pump mounting bolts are tight and the pump is not vibrating against the base or plumbing.
Replacing pump bearings typically requires a new pump motor or complete pump assembly.
