Toilet Flange Extender

[Stuart Richman]

Hi,

I'm installing an Oatey Set Rite toilet flange extender. A couple of questions.

1. A couple of the screw holes where the new flange (yellow) will sit directly over where screws are located for the existing lower flange. Those should be removed from the existing lower flange? Correct?

Is there any value in putting a thin coating of silicone between the parts?

Thank you

Do not use silicone on anything. The extender dumps the waste water well below the stack of spacers.
