Had some building work done on the house, this meant the soil stack had to be removed, previously it was inside the house, exiting out the roof. (see pic)
It's now been moved to the side of the house (outside) but not connected up yet as the bathroom needs doing. Part of the old stack is still in place above first floor level.
My question is, where is the best place to vent it? Connect up to the old pipe and have it vent out the roof, or continue the new pipe up the side of the house and have it vent there? or does it matter. Toilet location can be seen here.
