110 pipe drop

[randomrob69]

hello just wondered if anyone might be able to share any advice,

i'm going to install a 110 mm soil pipe to connect to the main soil stack,

When the pipe comes out of the wall it will have to follow the underside of the ceiling which is 79in long with a drop of 26in then it will have about 25in to reach the main soil stack.

Does anyone know if this drop will be to steep or if it will be acceptable?
thanks
rob
