Hello there. I am planning on turning a spare bedroom in my house into a bathroom. I have the required permission from the local authorities and have had a couple of local plumbers out to have a look and give estimates. To be honest the pipe work is something I would like to do myself as I have done this work in the past prior to getting someone out to give it the once over so to speak.
I have a Ferroli 24b condenser fitted. I have a problem in my existing bathroom where when I run the hot tap on the bath all hot water flowing from the basin stops. In the same manner when I run the basin hot water all hot water from the kitchen sink is stopped. The kitchen sink is closest to the boiler, then the basin and last of all the bath. Both plumbers told me that the bath was "stealing water from the other end users" but both gave me different ways this could be stopped.
One of the lads advised that all the pipe work should be 22mm reduced down to 15mm when it reaches the end user so as to give greater pressure. The other said the boiler was not big enough and all hot water pipe work should be 15mm. The pipe work at the moment is 15mm!! The boiler is only max 4 metres from the furthest end user and I find it strange that this is happening. Can someone advise on the correct manner for plumbing in the hot water as I intend to run a new hot water supply from the existing boiler position to the new bathroom which will be approx 7 - 8 metres to the final end user. I am 90% certain I should use 22mm reduced to 15mm but I just need some advice.
Hope someone can help
