    Basin removed but I want to use the pipes….can this be done

    I had a basin removed and my builder capped the pipes and plastered them into the cavity wall. If I want to resurrect them can I do that to plumb a washing machine into a new ‘utility’ area next to the pipes? My assumption is there will be a cold water pipe, hot water pipe and a waste pipe in...

    We're having the loft converted at the front of our house, and the plumber has routed the new water and central heating pipes via the rafters in the back loft (which isn't being converted).
