Sterling Water Water Hammer / Rapid Valve Transitions

Softener causes banging or water hammer noises during regeneration

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

High household water pressure, Fast-closing valve, Lack of water hammer arrestors, Loose plumbing supports

Safety: High pressure can be dangerous. If you suspect very high pressure, contact a plumber.

Steps:

1. Measure pressure: Use a pressure gauge on a nearby faucet. Ideal pressure is 40–80 psi.
2. Install pressure regulator: If pressure exceeds 80 psi, have a plumber install or adjust a pressure-reducing valve.
3. Add hammer arrestors: Install water hammer arrestors near the Sterling softener or at problem fixtures.
4. Secure piping: Ensure pipes are properly strapped and not loose.
