Hot Spring Air Leak on Suction Side / Venturi Issue

Air bubbles constantly stream from heater return or jets even when air controls are closed.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Loose suction-side union, Cracked suction fitting, Faulty air check valve, Air control valve stuck open

Safety first: Turn off power before tightening plumbing.

Check air controls: Ensure all air control valves are fully closed.
Inspect suction unions: Tighten unions on the suction side of pumps and circulation lines.
Replace air check valves: If air is being drawn in through a failed check valve, replace it with a compatible Hot Spring part.
