Noisy pipes or water hammer — Hilversum, Noord-Holland

Banging, clanking, or rattling pipes — often called water hammer — happen when water flow is suddenly stopped and the momentum creates a shockwave in the plumbing. This can loosen joints, damage valves, and eventually cause leaks. Other pipe noises include whistling from partially closed valves or humming from high water pressure. A plumber can install water hammer arrestors, secure loose pipes, adjust pressure regulators, and replace worn valves to eliminate the noise.
