How to get rid of water hammer noise or water arrester
“Water hammering” typically manifests as a loud bang heard after turning off a faucet, a phenomenon often mistaken for the sound of unsupported pipes, whether in new or older homes.
The primary way to distinguish between water hammering and the noise from unsupported pipes is by paying attention to the nature and timing of the sounds. Water hammering usually results in a single, loud “bang,” whereas an unsupported water line tends to produce a series of rapid, short, sharp noises. Interestingly, repeated instances of water hammering can also lead to a water pipe becoming unsupported, as the consistent jarring from the hammering can gradually dislodge the pipe from its supports. This interaction between the two issues underlines the importance of correctly diagnosing and addressing the underlying cause to prevent further plumbing complications.
