I want to drill a hole in a plastic pipe running from my sink on an outside wall. I can then put my Draper bendy waste pipe sink cleaning cable down the pipe and clear some of the gunk out off it. I would like then to fit a very small inspection plug into the plastic pipe, this will allow me in the future to put my Draper wire cable down it again in the future.
Does anybody know where you can buy these inspection plugs in the UK.
