Soil stack design

Hi All,

Please can i have some advice regarding a new location for my soil stack. My existing one is located internally in the Kitchen and is currently being arranged to be relocated outside.

If this is move outside it will not run vertically up the outside of the building and will need to have 2 x 45 degree bends fitted due to the bedroom window obstructing the stack.

From point of ground floor it will need to be designed,

inspection socket
2 Meter length - 110mm soil pipe travelling upwards
45 degree elbow facing left over extension roof (this will avoid bedroom window)
800mm length - 110 soil pipe
45 degree elbow - this will run alongside bedroom window vertically facing upwards
branch tee - branch then travels to left 1.5 meters to an inspection elbow into property connecting onto WC.
outlet of tee facing upwards - travel 2 meters with a AAV connected.

Is this acceptable ?

Many thanks for your input.

 

Please see photo attached.

This is the current installation with the soil pipe located internally and terminating through the pitched roof.
I would like the stack fitted to the right of the extension.

The French doors are being moved over 450mm to the right which will allow the soil pipe to be clipped against the wall, however in my previous post stated, it will need to have 2 x 45 degree elbows to move from under the bedroom windows to the left.

The roof has been lowered in pitch to now expose all plumbing waste pipes. The bath window is located above the extension.

Thanks

 

Many thanks for your replies.
The soil stack will terminate in the same position vertically as existing photo shows. No reason to fit a AAV other than wanting to terminate below eaves.

I have contacted a company that is arranging for the underground connection to be altered to new position.
