Thanks for this.
I have measured all taps and the all cold measured around 14-15 Lpm and all hot is around 9-10lpm. The mains in is on 15mm until it gets to the loft transferring to 22mm it then runs the length of the loft to other side to where the boiler is situated.
Should I be lose 4-5lpm on flow just going via the boiler?
