Is it bad if your pipes are knocking?
The water pressure that passes through the loose pipes causes them to bang against the wall, causing that knocking sound you hear. This problem only occurs while the water is running, so if the banging noise stops the moment you shut off your water, it’s a good indication that loose pipes are the culprit.
Why do I suddenly have water hammer?
Water hammer is usually caused in high pressure (e.g. mains pressure) water systems either when a tap is turned off quickly, or by fast-acting solenoid valves, which suddenly stop the water moving through the pipes and sets up a shock wave through the water, causing the pipes to vibrate and ‘shudder’.
