I purchased the new American Standard Optum VorMax toilet to replace our current American Standard toilet. When I removed the old toilet I found the brass closet flange was not screwed down and floating above a rough and uneven surface. I removed the uneven surface and replaced it with new 1/2" and 3/4" plywood, I used a 5" hole saw in the new plywood to fit around the lead bend and brass closet flange. I sealed the lead pipe to the new brass closet flange using plastic seal and peening it to the brass.
