Wouldn't recommend it. 3" is only for venting

you can buy a 3" toliet connecter. if its a cast iron you might have some hassle getting the connector in then you can buy a 3" sleve although there tricky to locate most merchants will be able to order it for you however if you do go for this method i sugest putting one of those things that close when you tighten the screw lmao forgot the name of them.. hehe but basically hose clip. but there are 3' tolet connectors avaliable with a pan connector on.
