I am upgrading my loft tanks on a lead main gravity system to the new poly tanks. Cold water tank and F&E
My current supply for both tanks is a single 15mm pipe from the airing cupboard up to the loft with 2 Tee offs for each tank, is this size enough? or will it cause water hammering as I do hear a rattling sound when I use the hot water?
I was thinking of keeping the 15mm for the F&E tank and tee off 15mm to 22mm at the airing cupboard and running and running a separate 22mm for the cold water tank and 15mm for the F&E tank?
would this help . Thank you
