Building control are ready to sign off the extension (within PD), however, the last remaining element which needs covering is the removal of rainwater from the roof...
We have a combined system so the rainwater can mix with all waste from the property in the stack. Currently the 68mm downpipe is just draining onto the border through a pipe I have set up as a temporary fix to keep water away from the house. He nipped up the other week and asked that the rainwater from the downpipe needs to either go into a soakaway or into a gully in the ground. He's now on annual leave for a fortnight.
I have laid the new patio now after having the underground soil connections repaired and renewed to accomodate a new toilet downstairs, so I'm trying to look for alternative methods. Aesthetics aren't a real concern as the wall the pipes are on is fairly out of sight.
Understand that connecting the downpipe into the stack will allow venting of gases into the guttering, so does anybody know if it's possible to have the trap above ground rather than in the gulley? It won't look idea but it'll stop the venting of gases into the downpipe.
