Hello Everyone
I currently have an incoming lead water main up to my internal stopcock, after the stop cock I have what appears to be 25mm mdpe running to my loft where it splits off into 22mm to feed my unvented cylinder.
Is there any advantage in terms of flow rate for my cylinder pressure etc if I replace the lead mains with 32mm mdpe instead of 25mm mdpe.
Or should I just use 25mm mdpe.
The run of the lead pipe is about 8meters, the run of the internal 25mm is about 10-15m.
Once the lead enters the property it goes under my living floor boards between the joists, would I need to lay the new mdpe in ducting even inside my house? Would insulation also be required?
Many Thanks
