Can wax rings be stacked on top of one another to make up for the extra space between the toilet bowl and toilet flange, and still create a watertight seal?
Although stacking two wax seals on top of each other seems to be a common practice, Oatey does not recommend this application. We recommend using a jumbo or extra thick wax ring instead the stacking method. Also consider raising the flange height with one of our spacer kits.
