just a bit of advice please. I am getting my old mains lead pipe replaced and replumbing the house. have put in new combi Baxi 105HE.
New mains is 25mm MDPE blue pipe. It will need to feed kitchen sink, dishwasher and washing machine downstairs, then upstairs for bathroom sink, shower, toilet then onto feed boiler. Bit concerned that boiler is at end of the line and could be robbed of pressure, so was thinking of reducing MDPE at stopcock to 22mm, taking a reducing tee off downstairs to feed kitchen sink/dishwasher, then running up wall, take treducing tee off to feed sink, shower and toilet, then reducing pipe to 15mm to feed boiler. does this sound over complicated?
Many thanks
