Hi guys,
would appreciate your thoughts on a small issue I have discovered post renovation. A new waste pipe was installed that runs in the wall through a new bedroom we recently had renovated. Whenever any waste water flows through the pipe from either the sink or the dishwasher there is a furious tapping sound coming from the pipe in the wall. I thought this might be some kind of thermal expansion but it is there whenever any waste water flows through the pipe. Also I believe it is a plastic pipe. I have attached a video. Apologies for the quality. You may need to turn up the sound somewhat to hear the tapping.
Many thanks for your advice.
