I am fitting a new bathroom suite which is fairly simple but I am struggling to decide how to connect the 4" waste from the loo to the existing lead pipe protruding from wall is there some type of flange or coupling available
go to a plumber's merchant and and ask for a WC pan connector. You can get them in various shapes and sizes. you may need one with a smaller diameter to fit into the lead pipe
first time on the site, thanks for the quick response, if I push in one of the staggered rib style connectors which I have seen and presumed were for std 4" pipe will I need to seal with silicone or a similar substance as well
Usually they seal alone. After pushing them well home fill around with plumber's mate. (that is the original sticky stuff like white tak, not the small tubes of namesake sold in sheds which is a two pack epoxy leak sealer that is supposed to work under water.
