I am looking advice on this. I currently have a gravity fed hot water system installed and am looking to have this converted to pressurised before installing 2 new bathrooms. At present my mains water coming into the kitchen is 15mm copper.
Does all 15mm copper mains to the cylinder have to be replaced with 22 for this conversion or is it just the outlets to the rooms?
Thanks
