I'm not knowledgable about the regs, but I was told that in any new installation, a door to a toilet cannot open directly into the kitchen. I.e there had to be two doorways between a toilet and the kitchen.
My husband has been in touch with building regs and they say we are ok but need to install a saniflo system as we have raft foundations and cannot dig through them. Has anyone any experience of saniflo? Are they reliable and can you use ordinary toilets and wash basins with their pumps?
