What's the best way to connect a 40mm waste pipe to (what I believe is) an LCC cast iron soil stack branch?
The waste is coming from a basin and a shower. The branch seems to be a 112.5-deg unequal single branch. Int. dia. I measure as 72mm, dropping to 40mm or so at the branch join. I'm struggling to find something that looks like it was designed for the job. Hoped these might work but, as you can see in the photo, are just a bit small!
