Notice that there is not one hole through the floor, when I pulled the plugs from the floor, I started with a drill bit in the hole saw shallow and after it was started pulled the bit out and finished with just the hole saw, not only is it a cleaner install, and looks more professional but it will keep my foam under the floor dry :) I don't see it getting wet unless somehow a hole gets poked in in. Thanks to Gorilla for the pro tip, hopefully someone else can use it on their project.
