Quick Answer: Vibrating Pipes When Toilet Flushes

The most common cause of a vibrating sound in the walls when you flush is an issue with the toilet’s fill valve – specifically, its diaphragm gasket. When this small part wears out, it becomes stiff and less flexible. When it tries to shut off, it bounces up and down, causing the vibrating sounds you hear.

How do I stop the pipes from vibrating when I flush the toilet?

When water flows through the pipes and the valves shut off quickly, water is forced to stop suddenly causing the hammer effect. To correct this problem, call a trusted plumber to help add a water hammer arrestor to the vibrating pipes. Also, you could replace the toilet’s fill valves with slow-closing fill valves.

Why do the pipes vibrate when I flush the toilet?

The purpose of a toilet’s fill valve is exactly what it sounds like: it refills the toilet with water once you’ve flushed it. Basically, the fill valve fills up from the bottom. So, the vibrations you end up hearing is actually the incoming water causing the hardened diaphragm to bounce around inside the fill valve.
