Just got a Toto Ultramax II with the unifit system. This is new to me and the last toilet I installed was in 1985. I had no problems with the last toilet install, and looking at the directions for the UniFit it looks pretty straight forward, but I am wondering if there are any tips or hints or things I should watch out for when doing this install? Looks like a common wax seal with out horns is what is needed, but are there other better choices. It actually looks like a pretty easy system and I don't foresee see any problems but thought I would ask for advice. Thanks for any help or hints. I do have my handy man buddy helping with the install, as it seems a little awkward and heavy for one person.
