That loud bang when you turn off a tap is water hammer — and it puts serious stress on your pipes and fittings. We diagnose the cause and fix it properly.
Water hammer occurs when flowing water is suddenly stopped, creating a pressure shockwave that travels back through your pipes. The result is a loud bang, thud, or rattling noise — and over time, significant stress on pipe joints, fittings, and appliance solenoid valves. Left untreated, water hammer can cause burst pipes, leaking joints, and premature appliance failure.
The causes vary: high water pressure, unsecured pipes, worn tap washers, fast-closing solenoid valves in washing machines and dishwashers, or missing air chambers. Our plumbers identify the exact cause and apply the right fix — whether that's a pressure reduction valve, water hammer arrestors, pipe brackets, or washer replacement.
Don't ignore these warning signs — acting early saves money and prevents further damage.
A single loud thud when a tap or appliance shuts off is the classic sign of water hammer — caused by the abrupt stop of water flow.
Pipes that rattle, shake, or vibrate during water use are likely unsecured and amplifying the pressure shockwaves.
Banging noises from inside your walls when a washing machine or dishwasher completes a cycle indicate water hammer in concealed pipes.
If washers keep wearing out faster than expected, repeated water hammer may be damaging the tap seat — a pressure issue rather than a washer issue.
Frequent solenoid valve failure in washing machines, dishwashers, or irrigation systems is often caused by excessive water pressure or hammer.
If you've noticed sudden changes in water pressure throughout your home, this can both cause and worsen water hammer.
