I am planning on converting a small bedroom into an ensuite shower room. The house is about 200 years old and there have been many modifications in the past (not all of them carried out in a particularly logical way !)
On one side of the room is an existing WC waste which continues up to vent through the roof. The Shower and basisin will be located on the opposite side of the room and their waste run under the floor, parallel to the joists.
Where the existing WC enters the soil stack there is not sufficient clear space on the pipework to fit a boss to connect the new waste due to pipe junctions. Just below the joists the soil pipe turns and runs horizontally for a short distance, I can get access to the pipe here and wonder if it is acceptable to have the new waste join the soil pipe vertically from above? (ie have the new waste turn downwards and drop directly down into the horizontal soil pipe through a boss)
Should I run separate wastes for shower and baisin or can I combine them into one?
Thanks in advance for any help / thoughts.
