Hi all, First time post here. I'm thinking about putting a toilet in an upstairs airing cupboard, but the house (semi-detached) has never had any toilets or piping etc upstairs previously. The cupboard is situated in the front corner of the main bedroom at the front of the house (detached side). The current bathroom is downstairs on that side but at the back of the house. The toilet is against the outside wall (detached side) and feeds straight into a manhole outside. Would i have any problems having piping etc running the length of the house towards the manhole? Or is it not possible?
