Possible Causes

Damaged valve cover O-ring, Cracked valve body, Loose valve head bolts, Improperly seated rotor and seal

How to Fix / Troubleshooting

Safety: Place the softener in bypass and depressurize the system by opening a faucet. Unplug the unit before removing the valve head.

Steps:

  • Identify leak source: Dry the area and observe where water emerges when the system is pressurized. Look around the valve cover seam and plumbing connections.
  • Tighten fasteners: Gently tighten valve cover screws or bolts evenly. Do not overtighten, as this can crack the plastic.
  • Inspect O-rings: Remove the valve cover and inspect the main O-ring and any port O-rings for cuts, flattening, or chemical damage. Replace as needed.
  • Check valve body: Look for hairline cracks in the valve housing, especially near threaded connections.

Resolution: Replace the valve head O-ring kit if seals are worn. If the valve body is cracked, replace the entire valve head assembly.
