What is the correct wax seal for a toilet flange that is flush with the floor?
*If you are attaching to a plastic Floor Flange, you would use a Kant Leak(which has the plastic hub installed with the wax seal) and use a hacksaw to cut a regular wax seal in half,still leaving it like a round donut. You put the Kant Leak on the flange, then mold the wax seal half on top of the Kant Leak. The 1/2 wax seal should be formed so when you put the toilet down it does not push into the center and down the drain. If you are putting the toilet onto a Cast Iron or Lead flange with a brass ring, DO NOT use the Kant Leak. Use one and 1/2 wax seals and do the same as I stated previously.
