In a friends recently built house I noticed that the 10mm central heating pies between the fllor and the TRv were covered in a plastic pipe which had a serrated inside .It seemed to have been slipped over the pipe before the fittings had been attached as the pipe was not split. has anyone seen this or know where it can be obtained .I know you can get the pipe covers that are split but my experience of them,well the ones I had anyway, is that they are not very good Stuart
