Score: 70/100Rankings
The Kohler GP85160 is a genuine 2-inch blue toilet flapper featuring an integrated adjustable float, designed specifically for 1.6 GPF two-piece Kohler toilets. It offers a tight seal to prevent leaks and includes durable, chlorine-resistant vinyl construction for long-lasting performance. The product comes with a 5-year warranty and is intended as a direct replacement for failing flappers in compatible models.
The Fluidmaster 506 is a universal, non-adjustable 2-inch flexible frame flapper designed for older pre-1994 toilets with 3.5+ GPF flush valves. Its main trade-off is the lack of adjustability and modern durability features, making it less suitable for water conservation. It is best suited for DIY users replacing flappers on older, high-volume toilets with irregular valves.
