Hi,
I'm wondering if I have made a c**k up.
As part of an extension/new kitchen I was keen not to have an unsightly kitchen waste pipe on the outside wall.
I installed a 110mm downpipe through the slab to swept bend underneath which connects to the back of a bottle gully on the exterior which in turn feeds to the foul water sewer. The intention was to connect the 40mm waste from sink/washing machine/dishwasher to the downpipe with a rubber adapter.
I was assuming the bottle gully would act as a foul air break but (of course) it does not. Is the rubber seal and trap under the sink going to be enough to stop foul air entering the kitchen? (and will it meet building regs)?
Thanks,
TJ
