I am going to use 22mm copper for the over flow on my unvented hot water tank.
Can i run this out into a gutter ? Outside where the over flow will go there is a large flat roof which you can walk on. It would be easy to just continue the 22mm copper along this flat roof and deposit into the gutter, but this might not be ok.
Or can the over flow go into my soil pipe running out through this back room ?
