Thanks for the replies.
With the house being 1900 it is already a waste in the hopper system so will be OK on that front if this doesn't work out.
The Downpipe is Cast Iron, I am not moving the WC much just a foot or so looking to put the new plastic waste into the existing connection...
Hi, I have looked for an answer to this issue and been unable to find one on the forum so it has prompted my first post.
I am reconfiguring a turn of the century bathroom and it will require me to move the WC waste and Sink waste.
The WC waste goes into the Soil Stack, the Sink waste...
