I have an external pipe which takes the soil pipes from the bathroom and shower room, combines them into this one pipe and then goes to the mains drainage. The pipe is below the window of the shower room, approx half way up the house.
Currently just above the point where it joins both soil pipes, its not capped. I understand this is not ideal (smelly) , but can you advise if this could be capped with a hinged vent lid, (cheap) or whether it should be extended past roof level and left open (not so cheap).
thanks!
