Possible Causes
Inlet and outlet reversed on Crystal Quest valve, Bypass valve left in bypass position, Cross-connected hot and cold lines, Bypass piping around softener
How to Fix / Troubleshooting
Safety first: Shut off main water and relieve pressure before altering plumbing.
- Verify bypass position: Ensure the Crystal Quest bypass handle is in the SERVICE position, not BYPASS or MIX.
- Check inlet/outlet: Confirm the house supply is connected to the INLET port and the house distribution to the OUTLET port as labeled on the valve.
- Inspect for cross-connections: Look for any tees or valves that might allow water to bypass the softener entirely. Correct plumbing as needed.
- Retest hardness: After corrections, test water hardness before and after the softener to confirm proper operation.
