Safety first: Turn off power before tightening or adjusting pumps.

Inspect mounting: Open the equipment bay and check that the Dynasty Spas pump is securely bolted to the base.
Tighten hardware: Snug any loose mounting bolts or screws. Do not overtighten plastic bases.
Check alignment: Ensure the pump is not under stress from misaligned plumbing. Adjust unions and supports as needed.
Replace isolation pads: If rubber mounts are deteriorated, replace them to reduce vibration transfer to the cabinet.

Strong vibration or rattling is felt through the spa cabinet when pumps run.
