Hi,
Just wondering if someone could let me know the maximum fall that can be used when installing rainwater pipework within a ceiling void (preferably to British Standards).
I'm currently co-ordinating the services on a job and have been using a fall of 1:100. I've never done drainage pipework before and like to know what is the normal fall used and what is that minimum fall that I can use!
As usual, the ceiling void is tiny and I'm struggling to get everything in!
Thanks for any help!
