Universal Toilet Repair Kit

The Korky 818GR fill valve and flapper kit fits most standard toilets and is built from plastic and rubber components that resist chlorine damage. It meets CUPC and ASSE standards and carries a five-year manufacturer warranty. Homeowners and maintenance crews can use it for new installations or to refresh ageing cistern parts.

Replaces Worn Fill Valves And Flappers

Swap this kit in when the existing fill valve runs continuously, shuts off slowly or the flapper leaks water into the bowl. The universal design covers the majority of two-piece and one-piece toilets without requiring special tools or model-specific parts. It is not suited for pressure-assist or proprietary flush-valve systems that need dedicated components.

Consistent Shut-Off Under Continuous Use

Chlorine-resistant rubber seals maintain a tight seal over years of daily fill cycles, preventing the slow leaks that waste water and raise bills. The plastic body resists corrosion from treated water supplies, so the valve continues to shut off cleanly rather than dripping after each flush. Steady performance reduces the need for repeat service calls.

Questions about this item

Will the universal-design body fit my toilet tank without trimming?

The valve body follows a universal design that fits most standard two-piece toilets without cutting or shimming the tank opening.

Which step do DIYers most often miss when installing the 818GR kit?

After threading the lock-nut, many forget to press the flapper squarely onto the flush-valve seat so the chain has no slack when the handle is released.

How often should the included flapper and rubber seals be swapped out?

The chlorine-resistant rubber typically lasts several years; plan to inspect the flapper and seal annually and replace them if they feel stiff or show mineral build-up.
