Autotrol softener allows hard water to bypass during regeneration (no soft water available)

Safety: Shut off water if re-plumbing is required.

• Check bypass position: Verify the Autotrol bypass is in the correct position for normal operation and not partially open to hard water.
• Confirm plumbing: Ensure the inlet and outlet connections on the Autotrol valve are correctly connected to the house plumbing.
• Internal checks: Some Autotrol valves use internal check valves to prevent hard water bypass. If these fail, replace the check valve assembly or the valve module.
• Test during regeneration: During a regeneration, test water hardness at a faucet. If hard water is still present, re-check bypass and internal seals.
