Hi Guys, Currently building an extension and all is going well. We have decided to take the back wall out to make down stairs open plan, however we will need to move the soil stack to the left hand side of the window. Could anyone suggest the best way to attach the shower waste and sink waste to the new soil stack or what connections I would require.
Use a collar with bosses and a rodding access. Don't put the rainwater back into it, run it to its own soakaway.
Thanks Phil, Rainwater pipe will be diverted on to the new roof/guttering down into the new soakaway.
