If you hear a loud knocking or shuddering noise when using a tap or shower, it’s most likely caused by a worn rubber washer in your home’s water supply system.
Most people believe the noise is caused by loose pipe work, when in fact it’s the movement of your taps loose valve (tap washer) or spindle movement (a loose sloppy spindle).
Here’s how to fix a noisy tap:
- Inspect the tapware that’s making the noise and the nearby water connection hoses or pipes. Sometimes it will only happen when the water is hot or cold (just the right pressure), this will help you to identify which tap is making the noise.
- When the rubber washer gets worn it has room to move around. When the tap is in a certain position the movement of the washer causes the washer to vibrate, which makes the loud noises. This can also cause surges in the water pressure.
- Turn off the water supply. Open and inspect the tapware.
- If the washer has room to move around, or looks worn or cracked, replace the washer & spindle ‘O’ ring. The ‘O’ ring is internal of the spindle and is easily replaced by winding the spindle outwards from its housing. Remove the ‘O’ ring, replace with new & apply lubricant (‘O’ rings & tapware grease are available at your hardware store).
- Re assemble and check for the noise and possible leaks.
- Your choice of washer can make a difference, if the noise is still there try a different type of washer.
- Water hammer can at times be quite difficult to eliminate.
