I have installed a new toilet in a new location so new drainage was required, the WC is installed at the opposite end of the house to the soil stack. I have cored a hole through the wall and then used an elbow on the outside wall to join the existing drainage, an inspection chamber has been installed so any blockage could be rodded. The BCO has been round to sign it off and he insists that it needs a sub stack to be installed.
I cant see any need for this, any opinions?
