If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Safety first: Immediately place the softener in bypass and shut off the inlet valve if necessary. Unplug the unit. Mop up any standing water to prevent slip hazards.
Locate the leak source:
- Dry the area and observe where water reappears: at plumbing connections, tank neck, or valve seams.
- Tighten any loose threaded fittings carefully; do not overtighten plastic.
Internal valve leaks:
- If water seeps from the seam between the valve head and tank, the tank O-ring or internal rotor/seal pack may be failing.
- Depressurize the system, remove the valve head per AO Smith instructions, and inspect/replace the tank O-ring and rotor and seal kit.
If the valve body itself is cracked, the entire control valve head must be replaced.
