I'm beginning to agree with your comment about the BCO. Defo only one stack as only one loo when we moved in.
Ever asked for a second BCO to give an opinion, I have lost faith in this guy.
No drawings needed as a simple velux conversion. BCO came round and agreed all positions of windows but didn't notice the stack. The carpenter who did the work will put it right but I want a simple solution as I really don't want the stack moved.
Hi
BCO has come around for final sign off of loft conversion and has just noticed the open soil stack is only about 2.5m from a velux.
I know Regs H1 state it must be 3m otherwise you need to go 900mm above window so no arguments with the BCO!
He has suggested bringing the pipe inside...
