Hi guys...
Just wanted to check.. am having a mixer shower installed.. the plumbe says i need to have a pressure reducing valve for my cold as it run from mains.. however, for this to happen he would need access to th pipes which are behind my newly tiles walls so obviously a proble there.. is it essential i have this valve.. i just had a new comb boiler (worcester 35CDi) put in (not sure if this info is helpful)
thanks in advanc
