Fluidmaster PerforMAX Flapper
Score: 88/100Rankings
The Fluidmaster 502P21 PerforMAX is a universal, adjustable 2-inch toilet flapper designed to resolve weak flushes, running toilets, and water waste in toilets with 1.28, 1.6, or 3.5+ GPF ratings. It features a dial-adjustable mechanism for customizing flush volume, Microban antimicrobial protection, and a solid frame to prevent twisting during operation. It is best suited for homeowners with most 2-inch flush valve toilets experiencing weak flushes, running toilets, double flushes, or high water use.
The Korky 54BP is a basic, universal 2-inch toilet tank flapper made of flexible, corrosion-resistant rubber, designed for standard plastic and brass flush valves. It offers a reliable seal and easy installation but lacks the premium durability and extended warranty of higher-tier Korky models. It is best suited for homeowners needing a cost-effective, quick replacement for standard gravity-fed toilets.
