Whether it sounds more like a vibration, a rattling, or a straight-up jackhammer, there’s no question that hearing a sound in your walls after you flush the toilet can be unsettling. Why would the toilet be making that sound? And is it the sign of a plumbing emergency? Typically, this is not an emergency and has everything to do with your toilet’s fill valve.

However, there are cases where it may be an issue with the plumbing inside the walls. If your water pressure is too high, that can do it too. Whatever the issue, it’s important you don’t ignore it, as you can experience disastrous flooding damage if a pipe suddenly bursts in your home.

If you try repairing or replacing the valve, and you’re still hearing a vibrating sound when you flush, our technicians at Ambient Edge can help. Give us a call at 888-230-8941 or send us a message on our website to set up a service appointment.

Diagnosing the Problem

In order to fix your plumbing emergency, it’s important to note exactly what happens when you hear the rattling in your walls. For instance, is the sound only coming from the toilet? Or do you also hear it when you turn off your faucet? Narrowing down the noise can help prevent plumbers from cutting into your walls, only to realize the sound is not coming from the location they thought it was.

The Toilet’s Fill Valve

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.

You can check this for yourself. Take the toilet tank lid off, then lift the fill valve float arm gently. If you don’t hear the vibration, then you have just confirmed the fill valve is the issue and you need to replace it.

A Loose Pipe

In some cases, it’s not the toilet itself that’s the problem; it’s a loose pipe in your wall. This is a pretty easy fix. All you need to do is secure the pipe to the wooden framing with pipe clips. If this is not something you feel comfortable doing, call a licensed plumber for assistance.

The Water Hammer Effect

A vibration in your walls can also be the result of something called the “water hammer” effect. When you have a water hammer, this means that the water in your pipes is hitting up against a valve that is shutting off too quickly, or “hammering.” This happens often with toilet fill valves and faucets.

There are several approaches you can take to fix this problem. For one, you can hire a plumber to attach a water hammer arrestor to your pipes, but this is an invasive process that requires the plumber to cut into your wall. An easier fix may be to replace your toilet fill valves with fill valves that are slower to close. These valves are called, fittingly, “slow-shutting fill valves.”

Random Vibrations

If you hear vibrations randomly coming from your toilet, not just when you flush, then the issue may actually lie with your toilet’s flapper. When the flapper wears out, water can leak into the toilet’s bowl, which results in a slow leak in your tank. Then, when the tank refills, it creates the vibrating noise. Flappers wear out faster if you regularly use chemicals to clean your toilet.
