Replacing Toilet Tank-to-Bowl Gaskets

If you're performing repairs to your toilet or need to remove the tank from the bowl for any reason, it's always a good idea to change your gaskets and bolts (especially if you haven't in a while) to make sure everything is still leak-proof. It's an inexpensive and easy way to help keep things in good working order.


Frequently Asked Questions

Q. "What's the difference between 'universal' and 'will fit'?"
A. There really isn't a big difference in the terms. For these tank gaskets, we use the term "universal" to designate gaskets that are designed to fit a wide range of toilets without reference to brand or model. Gaskets that have been made by a company other than the original equipment manufacturer (OEM), but that are meant to look and function exactly like a particular OEM part, we have designated as "will fit". This is mostly just to help you out when choosing among the wide variety of tank-to-bowl gaskets we offer.

Q. "How long 'should' the parts inside of my toilet last?"
A. That depends on a number of variables and which parts. Water quality is one of the major factors. If your water source is heavily chlorinated then many parts won't last long. Or if you have a lot of sand or grit or have a low pH or "aggressive" water source then parts simply won't last as long as the 'average' length. Also the quality of the parts matters. The replaceable parts such as flappers and washers/seals generally will last at least 4 to 5 years on "average." If you use a bowl cleaner some flappers won't even last one year. If your flapper has black "goo" on it then it is either due to age or quality of your water and if it feels soft then it's best to change it.
