For clanging sounds whenever water starts running through a pipe anywhere around your home, check for loose valves or elbow fittings and tighten them back down or completely replace them if necessary. Painting over old rust spots on internal pipes can also stop random noises from water hammer.
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.
Can water hammer fix itself?
