The kit pairs the Performax fill valve with a convertible Super Flapper that works as either a 2-inch or 3-inch toilet flapper. The Performax fill valve delivers 2x greater bowl refill compared to standard fill valves, supporting a more powerful flush cycle. This kit is installed by plumbers and experienced DIYers working on tank-style toilets. The convertible flapper design allows a single part to replace either flapper size, reducing the need to stock multiple SKUs.\u003c\/p\u003e\n\u003cp\u003eThis kit is suited for residential toilet repair applications where either a fill valve, a flapper, or both components need replacement. The universal design fits most 2-inch and 3-inch flush valves across common toilet brands. Water use can be adjusted on both the fill valve and the flapper independently, allowing the installer to balance flush performance against water conservation requirements. The kit is packaged as a single unit containing both components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eConvertible Super Flapper fits both 2-inch and 3-inch flush valves\u003c\/li\u003e\n  \u003cli\u003ePerformax fill valve delivers 2x greater bowl refill for stronger flush performance\u003c\/li\u003e\n  \u003cli\u003eAdjustable water use settings on both fill valve and flapper\u003c\/li\u003e\n  \u003cli\u003eUniversal fit across most residential tank-style toilets\u003c\/li\u003e\n  \u003cli\u003e2-piece kit includes fill valve and flapper in one package\u003c\/li\u003e\n  \u003cli\u003e7-year manufacturer warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a universal OEM-style replacement kit compatible with most residential tank-style toilets using 2-inch or 3-inch flush valves.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber or qualified DIYer following local plumbing codes.
