Hi All.
Apologies if this has been asked previously. I have searched for days but cannot find the exact answer.
I am installing a new shower room downstairs and need to connect the water waste (40mm) from the shower and basin. There is a 90mm cast iron soil stack right outside so this seems the best place to run my waste outlet to.
I know there are many options to connect to a 110mm pipe but the only Boss I can find to connect to 90mm is the McAlpine BOSS90TCAST-BL
The problem with this is it is made for connecting a condensate outlet so needs a 22mm hole. It doesn't sound sensible to reduce from 40mm to 22mm but there doesn't seem to be an appropriate boss for a 90mm pipe that a 40mm pipe can be connected too.
I know there have been suggestions of removing the whole stack and replacing with plastic but this seems like overkill to solve one connection. The other option I have come across is to cut a complete section out of the cast iron pipe and replace with plastic and then fit a boss but again I have not found anything for 90mm.
What other options are there? I would have thought a lot of old houses have 90mm stacks so would have been easier to find a solution but I have still not found anything that suites my situation.
Would appreciate any help!
Regards
