Got a toilet that keeps running or hissing?

Nine times out of ten, it's the flapper.

This replacement flapper fits most 2-inch flush valves and works with a bunch of brands – TOTO, Gerber, Kohler, and more.

It's a universal design, so you don't need to hunt down a brand-specific part.

The rubber is transparent so you can see if it's sealing properly, and it's made from quality material that won't degrade as fast as the cheap ones.

Installation is tool-free – just pop the old one off, hook the chain to the flush lever, and adjust the length so the flapper seals properly.

Takes maybe two minutes, even if you're not a DIY person.

Comes with a stainless steel chain and hook included, so you're not reusing the rusty old one that's half-corroded.

The chain won't rust or break like the cheap plated ones.

It's a 2-inch flapper, so measure your flush valve opening first – if it's not 2 inches, it won't fit right and you'll still have a leak.

But for most standard American toilets, this is the one.

Simple fix, cheap, and saves a ton on your water bill compared to a constantly running toilet.
