Hi! Im new here and have a question about drains. I am currently remodeling my bathroom and there is a cast iron elbow (for a toilet) that leads into a Y that brings in the shower and vanity. I plan to cut the cast iron off and run all plastic. I was planning on attaching a furnco to the existing cast iron drain (which goes to the trunk and is vented, as is the vanity and tub independently). Due to space I want to put in a sanitary T instead of an elbow for the toilet and bring the vented tub and vanity in up stream from the toilet. Are there any concerns that I should be aware of? Thanks in adavance for any help
