Davey Persistent Air Ingress on Suction Side

Pump runs but air bubbles are constantly visible in the pool return jets.

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

Leaking pump lid O-ring, Loose suction union, Air leak at skimmer or vacuum plate, Low water level drawing air into skimmer

Safety first: Turn off pump before opening any fittings.

Step-by-step checks:

1. Raise water level: Ensure water is at least halfway up the skimmer opening.
2. Check skimmer fittings: If using a vacuum plate, ensure it seals properly over the skimmer basket.
3. Service lid and unions: Clean and lubricate the pump lid O-ring, and tighten suction unions.

If bubbles persist, a pressure test of the suction line by a pool professional may be required.
