i'm currently renovating my house and after moving walls around etc have created a space big enough for a downstairs bathroom. my upstairs bathroom is above the kitchen of which the soil pipe ran up in a boxed unit in the corner of both rooms!!! i have now run the pipe out the kitchen wall and up the outside of the house thus creating square rooms .
however how would i put a downstairs toilet in with a near on horizontal waste? is there a flush unit of some sort? the distance the waste pipe would run is max 4m
plus how would i go about the legalities, would i need both planning and building control or just building control? it runs o the kiychen so would there have to be more than 1 door between them? thanks in advance
