In your case as you are having the drive ripped up, get a new mains pipe run

pressure/flow will be far less. And have a "full bore" stop cock in the
house.

I noticed you mentioned fitting a 'full bore' stop cock again elsewhere
today... by that do you just mean a stopcock with 22mm output as opposed
to 15mm, (like

'full bore' descriptor refering to something else?
