We have a small bathroom with the main stack running down the middle of a wall. We're aiming to move it into the corner of the bathroom.
First off, what is the minimal fall for a soil pipe? I believe it to be 2.5 degrees, can anyone confirm?
Secondly, to save having to mess about with the roof, we are hoping to keep the existing vent by connecting it in the loft to the new stack.
1) Does this still have to have a fall (even though it should only be for gas)
2) Does it have to be run in 4" pipe?
Cheers,
Fubar.
