Possible Causes
Worn seals allowing bypass, cracked piston, debris preventing full closure in service position, incorrect valve programming causing premature capacity exhaustion
How to Fix / Troubleshooting
Safety first: Place the valve in bypass and depressurize before internal service.
- Check capacity vs. usage: Ensure the programmed capacity and hardness match actual usage. If the system is undersized, it may run out of capacity before regenerating.
- Inspect piston and seals: Remove the piston and seal pack. Look for cracks in the piston or worn seals that could allow leakage. Replace with a Fleck piston and seal kit.
- Flush debris: Inspect the valve body for sand or debris. Rinse thoroughly before reassembly.
- Monitor hardness: After repair, test hardness at various times in the cycle to confirm consistent soft water.
