What is Water Hammer
Wikipedia describes Water Hammer as:
Water hammer (or, more generally, fluid hammer) is a pressure surge or wave caused when a fluid (usually a liquid but sometimes also a gas) in motion is forced to stop or change direction suddenly (momentum change). A water hammer commonly occurs when a valve closes suddenly at an end of a pipeline system, and a pressure wave propagates in the pipe. It is also called hydraulic shock.
This pressure wave can cause major problems, from noise and vibration to pipe collapse. It is possible to reduce the effects of the water hammer pulses with accumulators, expansion tanks, surge tanks, and other features.
That is a pretty the long way of saying that, Water hammer is the loud banging noise you hear in your pipes after turning off a tap.
It’s not a good problem to have, and it should be fixed immediately. Having your pipes vibrate and bang constantly can cause the pipes to crack and cause major damage to your home. Also, keep in mind that the damage will more than likely start in an internal wall, and you may not find out about it for a while.
