Overview
This two-pack from Lydia's Deal replaces worn flappers on toilets with a standard 2-inch flush valve, aiming to stop running water and ghost flushing on brands such as Kohler, TOTO and American Standard.
The listing is explicit that this is a 2-inch fit and not 3-inch, so measuring the flush valve opening matters more here than the word universal would suggest. Two flappers in the pack means a spare is already on hand for the next failure or a second bathroom.
- 2-pack of 2-inch flappers
- Chlorine-resistant rubber seal
- Compatible with Kohler, TOTO, American Standard
- Tool-free installation
Who it's for
Owners of a 2-inch-valve toilet, including many Kohler, TOTO, American Standard and Gerber models, dealing with a running toilet or ghost flushing. It does not fit 3-inch valve toilets.
Pros and cons
- Two flappers included as a spare
- Chlorine-resistant rubber for water exposure
- No tools needed to install
- Fits 2-inch valves only, not 3-inch
- Red color may not match all tank hardware
Performance notes
The flapper's ears attach to the overflow tube and the chain connects to the flush lever, with chlorine-resistant rubber meant to stay flexible under regular water exposure rather than hardening over time. A properly adjusted chain length is what keeps the seal tight between flushes.
