I've ripped out an ensuite and am re-fitting. As it stands, the electric shower, wc and cold water at the sink tee'd off of a 28mm pipe and all 3 were fed with 15mm from the next room (about 1.5m away). Is this correct or being that there's 3 utilities, one being 9.8kW elec shower, should I tee off the 28mm with 22mm for the 1.5m to the ensuite and then feed each utility with 15mm. Just don't want shower to loose power if wc flushed of someone uses cold at sink, or both!
Cheers for any guidance - I'm not sure on the standard practice for when to use 22 vs 15 - thought if 22 used you get greater volume/pressure, but I'm probably wrong??!
