My shower produces either very hot scalding water, very cold water or doesnt work at all when the toilet is flushed or the washer is on.
It has been plumbed in from the cold water tap on the bathroom sink. The pipework then runs the full length of the bath and up in to the shower unit.
Another un nerving part is that a hole (not pre made by manufacturer) has been cut from the shower main unit so the pipework can be fed up into it. It really doesnt look right to me but I may be wrong. My last property had a 'feed' comming down through the ceiling. Can anyone help.... Please !!!![/color]
