Want to use a corner branch to connect a toilet pan and the vent pipe at right anlges. The vent pipe will then run for 1metre along the floor before going out the wall and up to roof hight.
Question is,is this allowed ? I seem to remember something about not doing this because of cross flow. But if they can't be used why do they exist.
