How to Fix / Troubleshooting
Safety: Turn off power before opening any plumbing connections.
- Clean or remove filter: Take out the RivieraPool filter cartridge and rinse thoroughly. Test jet pressure briefly with the filter removed. If pressure improves, replace the filter.
- Check diverter valves: Ensure any RivieraPool diverter valves are fully open to the desired jet zones.
- Bleed air: Loosen pump unions slightly to release trapped air, then retighten.
- Inspect impeller: If pressure remains low, remove the pump wet end and inspect the impeller for broken vanes or debris. Replace the RivieraPool pump impeller or wet end if damaged.
