Korky 528 Universal Fill Valve

The Korky 528 is a plastic fill valve designed for residential toilet tanks. It meets CUPC and ASSE standards and resists chlorine damage. The white and black unit fits most toilets with a universal design and carries a five-year manufacturer warranty. It is sold new for standard bathroom maintenance or repair.

Suits owners replacing a worn fill valve

This valve works for most common toilet models that accept a universal fit. It is not for systems requiring a proprietary or non-standard valve design. Buyers needing a specialised flush mechanism or a valve for a unique tank configuration should look elsewhere.

Confirm your toilet accepts a universal fill valve

Check that the existing valve mounts and height are compatible with a regular universal design. Verify the tank dimensions allow proper installation without interference. Ensure local plumbing codes accept CUPC and ASSE certified components.

Questions about this item

Will the Korky 528 Fill Valve connect to my existing water supply line?

The valve uses a universal design that fits most standard toilet connections, so it attaches directly to the typical supply line already in place.

Does the Korky 528 Fill Valve work with older toilet tanks that have a different mounting pattern?

Its universal fit covers the vast majority of tanks, including many older models, without needing extra adapters.

How can I confirm the Korky 528 Fill Valve is operating correctly once installed?

The tank should refill quietly to the marked water line and then shut off completely, with no continuous running or leaking.
