Possible Causes
Drain line disconnected or broken, Internal seal failure causing constant backwash, Cracked Lindsay valve body, Incorrect drain line sizing causing sensor misread
How to Fix / Troubleshooting
Safety first: Shut off water and power. Be prepared for water discharge at the drain line.
- Inspect drain hose: Follow the entire length of the drain line. Repair any breaks or loose connections. Ensure the end is not submerged in a floor drain.
- Check for constant flow: With the unit in service, observe the drain port. Any continuous flow indicates an internal leak.
- Inspect valve internals: Remove the valve cover and check the main piston and seals for damage. Replace with a Lindsay seal kit if worn.
- Check valve body: Look for cracks around the drain port or internal passages. A cracked body requires full valve replacement.
