Scalemaster Continuous Bypass or Internal Leak Through Valve

Softener emits a constant hissing or trickling sound even when not regenerating

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Worn or damaged seals in Scalemaster control valve, Debris lodged in valve seat, Bypass valve not fully closed, Cracked internal valve body

Safety first: Continuous flow can waste water and may indicate a fault. Do not ignore.

Step-by-step checks:

1. Check bypass position: Confirm the bypass is fully in "service" and not partially open.
2. Listen at drain line: If water is constantly running to drain, the valve is not sealing properly.
3. Power cycle and observe: Turn power off and on to ensure the valve is in the correct service position.

Internal seal and piston replacement requires valve disassembly and should be performed by a qualified technician.
