Move Soil Pipe

Updated pic. Pipes are to the left of the coloured strips drawn on to the pic.

The short answer is no, you cannot divert the soil stack into that pipe. 

The full width of that 💩  pipe needs to run all the way into an inspection chamber.  You can add a new branch, subject to building control, but you can't use the one for the rainwater.

I don’t necessarily want to divert the soil stack to that specific pipe, more so the same drain.

I’m happy to change the current 70mm waste pipe to a 100mm pipe then have an angled diagonal soil pipe to connect to it.

Or is the pipe diameter not the issue? If so, would you mind expanding a little on why it would not be possible.

Well, if you are sure that you have a combined drain for rainwater and waste water and if you replace the pipe with 110mm one, I don't see any problems.

it's most likely that the existing gutter downpipe is connected to 110mm pipe going to the inspection chamber.

This is where the waste pipes join the gutter pipe (blue pipe on my pic) which then runs vertically in to the drain.

I think the gully in the ground will need replacing with something like this

Thanks grumbler. Happy to chuck whatever money it takes to get it sorted, but if I can use the current waste drain I’m hopeful it’ll make the job a lot easier.

I’ll get a plumber in but it’s been useful to get some opinions / info on it tonight.
