I need to re-route 28mm copper pipe, in our bathroom, which is the flow & return for the hot water cylinder heat exchanger coil. A new boiler was fitted couple of years ago and was converted to a fully pumped system at the same time.
My question is, can I use 22mm pipe for the re-route, (approx 1.5M section) now that H/W is pumped and not gravity fed? Could I even use plastic push fit?
I assume that when I do this, closing the supply from the f&e tank and draining down the C/H through the lowest rad will also drain the H/W flow & return circuit ....
