Firstly, excellent website even for a complete novice like me. I am planning to install a toilet in a worskshop which may also be used as a living space. I've been told by the contractor that I need to have a demarcation chamber. He says it should be internal - will it smell? Also, what are implications/regulations for having it outside ( a yard common to the other workshops). ???
you caan have internal stink pipes, but advise have it outside if poss. Dont see problem with having everything outside any chance of pics or site layout?:)
