How to Fix / Troubleshooting

Safety: Unplug the unit and close the inlet valve. Depressurize by opening a downstream faucet.

Steps:

Inspect leak source: Dry the area and observe where water first appears: at the tank/valve joint, fittings, or cracks.
Tighten head: If the AquaClean valve head is threaded onto the tank, gently tighten it by hand. Do not overtighten.
Replace O-ring: Remove the valve head, inspect the large tank O-ring for nicks or flattening, and replace if damaged. Lubricate with silicone grease.
Check for cracks: If the valve body or tank neck is cracked, the component must be replaced.

After reassembly, slowly restore water and check for leaks under pressure.

Water softener is leaking from around the valve head or top of the mineral tank.
