I want to replace my existing toilet and connect the new pan to the existing 1959 cast iron soil pipe. The pipe exits at a fairly steep angle and has a large flange that the existing pan is puttied into (and it looks a mess!) The soil pipe is approx 4.5" outside diameter and appears to be marked 4". I've uploaded some pictures to:
Due to the steep (in excess of 14 degrees) exit angle I guess most of the available Multikwik and McAlpine range won't fit so only the flexible ones, such as the McAlpine WC-F23R, will fit? Or do I keep the flange and putty the new pan back in?
Advice welcome please so I minimise the trips swapping adapters and have the loo out of service for the minimum time :)
TIA
