Culligan Air in Plumbing from Drain or Brine System

Softener causes air spurting from faucets after regeneration

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

Drain line sucking air, Brine line air leaks, Improper drain termination, Low water level in brine tank

Safety: Bypass the softener if air surging is severe, then investigate.

Check drain termination: Ensure the drain line discharges into an air gap or standpipe without being submerged, but also without allowing air to be drawn back into the valve.
Inspect brine line fittings: Tighten brine line connections at the valve and brine tank. Replace cracked tubing.
Observe regeneration: Watch the unit during brine draw and rinse for signs of gurgling or air intake at the drain or brine connections.
