Jets or suction fittings vibrate loudly or rattle during pump operation

Safety first: Unplug the spa before tightening any fittings.

• Bleed air: Remove airlocks by loosening the upper hose connection until water flows steadily, then retighten.
• Tighten fittings: Hand-tighten any accessible unions or collars that feel loose.
• Check placement: Ensure the pump/heater unit is on a stable, level surface and not touching walls or objects that can amplify vibration.

If vibration remains severe, internal mounting or pump issues may be present and should be inspected by a technician.
