How to Fix / Troubleshooting
Safety first: Turn off water to the softener, depressurize the system, and unplug power before disassembly.
- Identify leak source: Dry the area and observe where water first appears: at the tank/valve joint, side ports, or top cover.
- Tighten connections: Gently tighten union nuts and fittings. Do not overtighten plastic parts.
- Replace O-ring: If leaking at the tank/valve joint, remove the valve head, inspect the large tank O-ring, and replace with a new Lindsay tank O-ring lubricated with silicone grease.
- Inspect for cracks: If the valve body is cracked, replace the entire Lindsay valve assembly.
