Toilet Tank Gasket

By: Joe Truini

A toilet tank lid that doesn’t fit properly is dangerous if it falls off the tank, and the noise of china scraping china is truly annoying. To solve this problem simply apply a bead of 100% silicone caulk to the top lip of the toilet tank and allow it to dry (usually overnight). Once dry, the silicone forms a gasket that keeps the lid from sliding around and eliminates that nasty grating sound.

    Hi Rich,
    It appears that the wax ring that seals the toilet to the floor flange is leaking and needs to be replaced. Check out our article on How to Remove and Replace a Toilet to see the process that is involved.

    My toilet is leaking from the bottom, at the floor. There is no water leaking down from anywhere. It is coming from around the bottom and has loosened the caulking seal. Is it possible there is a gasket or a seal that has been broken? I’m a do it myself person and believe I can fix it, if I know what the problem is. Help?? Thanks. Rich

    One thing to make this just a little bit better. After applying the silicon, add a piece of Handy Wrap or something simular across the top of the tank. Then place the lid on top of that. Let set for about 24 hours. Remove top and then the plastic wrap. Now replace top on tank. This makes a perfect gasket.
