Bathroom Refit 15 or 22mm cold water pipe

[peterduckett]

Im currently living in a 1950s semi and we have terrible water Pressure and Flow around the house, Probably not really help by a share supply pipe.

We are looking to refit the bathroom and was wondering if it would be beneficial to upgrade the current cold water pipe from 15 to 22mm and T off in 15 mm for toilet and basin etc.

Due to how the house was extended the current setup is as follows

StopCock --> 2m --> Kitchen sink/ outside tap --> 10m --> basin --> 1m --> toilet --> 4m --> shower --> 2m --> combi

so for now i was hoping to replace as much of the 10m in 22m to reduce static pressure and increase flow in the hope when we get rid of the share supply pipe we upgrade the rest.

Any pit falls problems? Advice?

It'll probably make very little difference to anything other than your basin, which might see a slight improvement. If you have good static pressure and enough space you could fit an accumulator
