Safety: Turn off power before adjusting pump mounts.

Inspect mounts: Check that RivieraPool pumps are securely bolted to their base and that rubber isolation pads are intact.
Reposition plumbing: Ensure plumbing lines are not rigidly pressing against the cabinet or shell.
Tighten hardware: Tighten loose mounting bolts, but do not overtighten to the point of crushing isolation pads.
Replace pads: Install new RivieraPool pump isolation pads if existing ones are flattened or missing.

Spa cabinet or shell vibrates excessively and the noise is transmitted into surrounding structures.
