I am replacing a toilet that is a piece of junk with a TOTO Drake. After I removed the toilet, I discovered the top of the flange is about 3/8 inch below surface of the tile floor. Furthermore, the edge of the tile cutout overhangs the some parts of the flange rim, so I do not have unfettered access to the flange. The original installation used a single wax ring with funnel, and to my knowledge it never leaked. What do you all recommend I do here? By the way, the top surface of the anchor screws in the flange appear rusted. Should I replace these? Is it normal for them to rust? This toilet was installed by the builder when this house was built in 1997.
UPDATE: Well, my new TOTO Drake (elongated bowl w/ Sanigloss) has been in for about three weeks, and so far, no problems. I'm shocked - my first toilet installation and I didn't screw it up - a miracle. This is a great toilet - I am so happy to be rid of that Mansfield 160 (hope I can name names here). I went with the single extra thick (No Seep 10) wax ring - haven't seen any water on the floor, so I guess I did OK. While the toilet base is near perfectly level, I could not get the tank to true level and get contact on all three points. I don't know how important that is, but the toilet is doing its job. Thanks for all who offered advice and guidance - it was much appreciated.
