Thanks for that,.
I am thinking of feeding say, 1 metre of 15mm Copper pipe from the relief valve outlet into the old 22mm overflow pipe (from the now redundant F&E tank) and adding an elbow at the outside end to turn the outflow towards the wall.
My thinking being that the gap between the 15mm and 22mm pipes will serve a similar function to a tundish, ie act as an air break
Think this will be OK? or are there issues with using plastic for pressure relief purposes?
