Just discovered a big leak in the hot water pipe somewhere in the pipes running under the floor then up the back of the sink unit but can't see how to get at the pipes and no clues on the internet either ! I have a Herald Motorhome with an integrated foldaway basin / toilet unit in the bathroom (possibly a Thetford or a Contessa C400 unit). I guess that I need to remove the panels under the foldaway basin to access the hot pipe, but how ? There are no obvious screws, so maybe it has to be torn out ? Help !!
