fluidmaster red flapper

Genuine Fluidmaster 502074 (502) Adjust-A-Flush flapper. This high-performance replacement features an integrated timing dial, allowing you to fine-tune the volume of water released during each flush. Pro Tip: If your toilet has a high-volume flush that you don't actually need, use the dial on this flapper to decrease the water flow. It’s a "silent leak" specialist—if you see water rippling in the bowl or hear the tank topping itself up occasionally (ghost flushing), this chlorine-resistant seal will solve the problem while giving you control over your water consumption.
