Hi all
I checked the faq and couldn't find the answer, and a search leads me to older responses. Would appreciate your help.
I'm having a new unvented system installed which requires the existing gaspipe being enlarged/replaced. This means digging up some screed. Once replaced, does building regs suggest the cover/screed above need to be a certain depth?
I've read for copper pipes its 25mm minimum. Is this a recommendation or a requirement per building regs.
Thanks a lot.
Dan
