The Korky QuietFILL Fill Valve is a replacement water fill valve designed for compatible automatic fill and water-level applications. The adjustable 8" to 11-5/16" range allows it to fit supported installations where the original valve needs to be replaced due to wear, sticking, leaking, or poor shutoff performance.

Use this part when replacing a worn, damaged, missing, or failed original component in a compatible system. Always compare the existing part, equipment model, dimensions, electrical ratings, and part number before ordering to confirm correct fit and application.

Korky – Toilet Fill Valves, Flappers & Plumbing Repair Parts

Who is Korky?

Korky is a U.S. toilet repair brand known for fill valves, flappers, flush valves, tank-to-bowl gaskets, and universal repair kits. The company emphasizes universal-fit repair parts designed and manufactured in Wisconsin, making it a familiar name for plumbing repairs beyond the pool and spa category.

What products does Korky specialize in?

Korky makes toilet fill valves, flappers, flush valves, seals, gaskets, handles, and repair kits for common residential toilet problems. Their parts are designed to solve running, leaking, weak flush, and slow refill issues without replacing the full toilet.

Why choose Korky parts for your pool or spa?

Choose Korky parts when a repair calls for a widely compatible toilet component with straightforward installation. Universal-fit designs can reduce guesswork, while correct sizing and gasket selection help prevent leaks and repeated service calls.

How do you identify and choose the correct Korky part?

Identify the failed toilet part, toilet brand and model when available, flush-valve size, flapper type, tank configuration, and whether the issue is leaking, running, filling, or flushing. Compare dimensions and connection points before ordering.
