If you hear a loud “thud” or knocking sound in pipes when a tap shuts off, that’s not just a funny noise. It’s often water hammer – pressure surges when flow suddenly stops. Over time, these shocks can stress pipes, loosen joints, and even cause leaks.
Catching it early means you can ask a plumber to check pressure levels, install arrestors, or adjust valves. Sometimes even changing how quickly taps close or fixing loose pipe supports helps.
Leaving it until pipes have actually burst or fittings have failed ends up far more expensive and messy. Your ears are giving you a maintenance hint; it’s worth listening.
