Discuss 22mm or 15mm to baths on uvented system in the Plumbing Jobs | The Job-board area at PlumbersForums.net
For a house supplied by an unvented hot water cylinder is 15mm or 22mm usualy taken to the bath taps. I know on a combi its only 15mm require as the cold supplying the combi is only 15mm.
i believe 15mm is fine but 22mm is recommended
10mm to basins why?
So would people feed a full bathroom room shower, toliet, basin, bath off 15mm?
