That sudden bang in your pipes isn’t “just the house.” It’s water hammer—a pressure shockwave that hits when a tap or appliance valve shuts fast. Beyond the noise, it can crack joints, split pipes, and stress dishwashers and washing machines.
Common triggers include high water pressure, quick-closing mixer taps or appliance valves, missing or failed arrestors, loose pipe clips, and long straight pipe runs. If you’re noticing louder bangs, rattling pipes, damp spots, or musty smells, it’s time to act.
What helps:
• Test and regulate water pressure
• Fit water hammer arrestors at washing machines and dishwashers
• Restore air chambers where suitable
• Secure loose pipes and replace worn valves
Some fixes look simple, but incorrect pressure adjustments or poorly fitted arrestors can create new issues. A licensed inspection is the safest way to diagnose the exact cause and stop the problem for good.
