How to choose
- Fill valve: refills the tank after a flush; universal adjustable-height valves fit most two-piece toilets.
- Flapper: seals the flush valve opening; match the size (2 in. or 3 in.) and, for brand-specific toilets, the maker's style.
- Kits: a fill valve plus flapper kit replaces both wear parts in one visit.
- Stock by fleet: list the toilet brands and models in your buildings and keep their flappers on hand; universal fill valves cover most of the rest.
- Running toilets: a worn flapper is the most common cause of a toilet that keeps running.

Universal or brand-specific parts?

2 inch or 3 inch flapper?
Look at the flush valve opening at the bottom of the tank: older and many standard toilets use 2 in. flappers, while many newer and high-efficiency toilets use 3 in.
Why does a toilet keep running?
The most common causes are a worn or warped flapper, a chain that is too short or too long, or a fill valve set too high so water spills into the overflow tube.
