Water hammer is a common issue that can be fixed with a simple solution. Water hammer is the term used for the sound of knocking, thudding, or hammering coming from your pipes after you flush the toilet.

This sound is caused by a valve suddenly shutting off, causing the trapped water to hit the pipes' walls. The noise is usually caused by the rush of water being abruptly stopped.

Installing a water hammer arrestor can effectively reduce the sound. The arrestor absorbs the sudden shock of the water rush, making it a simple fix.

To install the arrestor, turn the water off and drain the toilet's pipes. This is a straightforward process that can make a big difference in reducing the noise.

If you still hear thudding or hammering after installing the arrestor, you may need to contact a professional for help.
