Hi all,
Water pressure and flow rate are not brilliant, British Gas said the flow is too low for a combi-boiler. So I fancy replacing the very old (not lead) water main with 25mm or 32mm mdpe. I know all the caveats, 750mm deep, lined with sand, keep the trench open until inspected etc. Few questions:
Length, house to pavement stop-cock ~15m.
1. I guess a larger bore pipe just increases flow (not pressure)(?)
2. Will the water company increase the pipe diameter between the water main in the street, and my pavement stop-cock?
3. If the answer to (2) is no, then will I achieve anything replacing my part of the pipe?
4. Can the water company "do" anything (other than ensure my stop cock is fully open) to increase the water flow rate, without digging?
Thanks for your help!
