Has anyone seen any place selling grommets that can be used in a bucket lid that are big enough to fill rubber stopper sized holes? I want to take out my airlock sized grommet, and drill the hole bigger so that I can use a larger grommet and a blowout hose.
You should be able to find them in any hardware store that has a decent electrical department. I know I have seen them at Fleet Farm: http://www.fleetfarm.com/search/grommet
If you don't have those in your area, I'm sure Home Depot carries them as well.
I would just leave drill the bigger hole and not worry about a grommet. If you install a grommet AND a rubber stopper, then that would be a double rubber. From what I learned in health class, that's a big no-no
But seriously, the big rubber stopper should be enough to seal it without the big rubber grommet.
