Hi all,
I am going to replace the lead pipe coming from the street to my home (Scottish Water will be doing the connection).
I have most of the details from Scottish Water though I have a few questions regarding MDPE as I am mainly familiar with 22mm and 15mm piping.
My questions are:
1) I understand using 32mm vs 25mm MDPE will not make much difference regarding the pressure, but should help regarding the flow rate.
Considering the water pipe going to my combi boiler is a 15mm pipe (to produce hot water), would it make a difference using 32mm vs 25mm when opening the hot water tap on 2 different sinks? (I am wondering if this would help increasing the flow of hot water or I am over engineering things)
Note that the MDPE run from the street to the house is 10 metres.
2) If I run a 32mm MDPE pipe from the street to my house, do I have to use a 32mm stopcock first and then reduce to 22mm? Or can I reduce first reduce to 22mm and connect a stopcock after?
3) Is a check valve required before the stopcock?
4) 32mm to 22mm stopcock does not seem common, what is the most suitable set-up? (2 bathrooms, with main Scottish Water stopcock 10 metres away)
Thanks a lot!
