Types of noisy pipe problems

Most noisy pipe problems have a clear mechanical cause and can be fixed in a single visit. Understanding the type of noise helps your plumber diagnose the issue before they arrive.

Water hammer: a loud bang or thud when a valve or tap is closed quickly
Whistling: a high-pitched squeal from a partially open or worn valve
Hissing from the toilet cistern: often a worn fill valve or float
Creaking or ticking: pipes expanding and contracting with temperature changes
Gurgling from drains or toilets: a blocked or poorly ventilated drain stack
Rattling under floorboards: a loose pipe clip that needs re-securing

Common repairs for noisy pipes

Water hammer arrestor fitting

A water hammer arrestor is a small device fitted to the pipe near the problem valve. It absorbs the pressure shock when water flow stops suddenly, eliminating the banging noise at the source.

Pressure reducing valve

Mains water pressure that is too high puts stress on your entire system and is a common cause of both water hammer and whistling. A pressure reducing valve brings the pressure down to a safe, quiet level.

Pipe clipping and securing

Pipes that are not properly supported vibrate against joists and walls when water flows through them. Adding or replacing clips and brackets stops the rattling without any major work.

Valve replacement or adjustment

Worn or partially closed valves are a leading cause of whistling and hissing. Replacing a failed valve or adjusting a cistern fill valve is usually a straightforward job that restores quiet quickly.
