Lindsay Internal Bypass to Drain

Drain line drips or flows water constantly even when not regenerating

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

Worn or cut main piston seals, Debris lodged in drain seat, Misaligned cam not fully closing drain, Cracked drain port in Lindsay valve body

Safety first: Turn off water and power, and relieve pressure before opening the valve.

Confirm constant flow: Observe the drain hose with the unit in service. Any continuous flow indicates an internal leak.
Inspect drain seat: Remove the valve end cap and inspect the drain seat area for debris. Clean thoroughly.
Replace piston/seals: Install a new Lindsay piston and seal kit, lubricating O-rings with silicone grease.
Check cam alignment: Ensure the cam returns the piston fully to the service position at the end of regeneration.
