Below is the floorplan of a small extension, its only the bit under the rooflight section that forms the extension and will have a slab poured over it.
Green is the existing soil stack that feeds upstairs and vents through the roof.
Purple is a new position
Cyan is a new position
Yellow is the ground box gas meter so the soil pipe can not exit here
Red is existing pipe to sewer
Orange is the proposed new inspection chamber
Green is currently connected to red with a straight run followed by a 30deg bend.
Can I have any bends or T's under the slab or do i need direct routes out to each position?
