Korky Adjustable 3-Inch Flush Valve Kit – Made in USA | Tank-to-Bowl Gasket, Fits Toto/Mansfield/American Standard - 5030

Versatile, Easy-Install 3-Inch Flush Valve Kit

The Korky 5030 is a flexible solution designed for many 3-inch, two-piece toilets built after 1997. The setup offers tool-free height adjustment from 7" to 11.5", allowing you to align the drain path without specialized tools or drastic modifications. An oversized flush tube and funnel help manage water flow with confidence, potentially reducing the risk of floods during flush events. The kit includes a premium 3" flapper and a sturdy tank-to-bowl gasket to promote a tight, leak-resistant seal as part of a complete rebuild, so you can refresh performance with a single, straightforward upgrade.
