Similarly, why do my plumbing pipes knock?
In most cases, knocking pipes are caused by variable water pressure in the main supply pipes coming into your home. However, when the air used in pressurizing those pipes leaks or is depleted, water moves suddenly and violently, creating the knocking sound as it traverses the length of the supply lines.
Also Know, how do I stop my water pipes from vibrating? If water pressure is the root cause of the vibrations, a trusted plumber can introduce a pressure-reducing valve to mitigate the problem. If the vibration of the pipes occurs after a sudden, banging sound, your system may be experiencing a hydraulic shock, commonly known as a water hammer.
Secondly, can knocking pipes cause damage?
More than just produce an annoying clamor, water hammer can actually damage the pipe connections and joints, resulting in leaks and costly repairs. Or worse, the noise may also indicate a larger problem like excessive pressure in your water supply lines or loose piping.
What does a water hammer sound like?
“The noise you hear is the pipe moving because of shock waves.” But worse, prolonged water hammer noise like this can sometimes cause pipe fittings and valves to fail and pipes to burst. Properly installed plumbing contains air pockets or chambers that compress when a shock wave hits them, muffling that water sound.
