Re-Route Vent for soil stack

[oyeomans]

I am currently planning a new bathroom suite at home and currently have the soil stack running inside the bathroom up through the loft to vent outside. What I am thinking of doing is cutting the soil stack inside the bathroom and then run it through the wall to outside and then up the wall so that it can vent that way. This is so that I can put fitted units in and will be hiding whats left of the pipe inside at the back of one of the units. There will be no other wet inlets above the point where I am cutting, can anyone think of a reason why I can't do this or think of a better way.

Hi That will be fine. But the vent needs to terminate 900mm above any openings to the building (window etc) and or 3m away (Horizontal) from openings. It can be run in 75 mm if required. But many use air admittance valves which if within compliance can be housed at high level in the units you mention. Good Luck

Thanks for that. thought you could only use air admittance valve on a sub stack though. I dont fancy using one anyway, think I would rather just drill a big hole and be done with it, 75mm sounds a lot easier hole to drill though.
