Korky

Korky toilet repair parts help homeowners replace leaking flappers, faulty fill valves and worn tank gaskets. You can replace the part causing the trouble once you’ve found where the water is going. A fill valve that cycles on can be responding to a leaking flapper or flush-valve seal.

Korky is the toilet-repair brand of Lavelle Industries, a U.S. rubber and plastics manufacturer. Its products are designed and manufactured in Wisconsin. Its original toilet flapper dates to 1954.

Match the flapper to the valve

Korky offers universal flappers, specific-fit flappers and flush seals for toilet brands including American Standard, Kohler, Mansfield and TOTO. You’ve got replacement options. Match the valve style, size and attachment points inside your tank.

Korky’s Fit-All flapper accommodates two-inch and three-inch flush valves. For tower-style valves, Korky offers a kit containing replacement seals for Kohler and American Standard applications.

Korky Plus uses Chlorazone rubber that resists municipal-water chloramines. That’s a practical reason to choose it for a tank supplied with treated water. Before fitting the replacement, clean debris from the sealing surface and adjust the chain so it has slack when the flapper closes.

On Korky’s chain-float arrangement, moving the float down increases flush volume and moving it up saves water. Test the flush after each adjustment and leave the setting where the bowl clears reliably.

Replace and adjust the fill valve

Korky offers universal replacements for faulty fill valves and ballcocks. Before replacement, check that the supply valve is fully open and the supply line is free of kinks or restrictions. Shut off the water before inspecting the fill-valve inlet for debris.

For removal, shut off the supply, hold the handle down while flushing, and sponge out the remaining tank water. Disconnect the supply line, remove the mounting nut and lift out the old valve.

For Korky’s twist-lock height adjustment, hold the bottom and turn the top counterclockwise to unlock it. Position the water-level mark about half an inch below the top of the overflow tube. Remove the valve and turn the top clockwise to lock it, with the ribs and pegs aligned.

Install the mounting nut with its beveled side up and tighten it by hand. On the standard refill-tube arrangement, the included metal clip holds the tube at the overflow; keep the tube positioned at the clip because pushing it down inside the overflow can create a siphon.

A Korky kit containing a fill valve, flush valve, Ultra flapper, tank-to-bowl gasket and hardware covers several components, with flush-valve replacement generally requiring tank removal on a conventional two-piece toilet.

Gaskets and handles finish the repair

Korky’s tank-to-bowl gaskets seal the joint between the tank and bowl. Its wax-free toilet seal serves the floor connection. Locate the wet joint before choosing the seal; Korky’s tank-to-bowl gasket options include two-inch and three-inch sizes.

Korky StrongARM handles and levers include a Faucet Chrome style. Match the mounting position and check that the lever moves freely inside the tank through a full flush.

Frequently Asked Questions

How do you adjust a Korky fill valve?

Hold the bottom and twist the top counterclockwise to unlock the height adjustment. Set the water-level mark about half an inch below the top of the overflow tube, then remove the valve and twist the top clockwise to lock it with the ribs and pegs aligned. Too high can leave the water running; too little tank water can leave you with a weak or incomplete flush.

Why is my Korky fill valve hissing?

A hiss can be water passing through the valve, but continued running after the tank fills needs a closer look. A leaking flapper or flush-valve seal can make the valve cycle on again, so the noise doesn’t necessarily mean the fill valve needs replacing. Check for a tight flapper chain, debris under the seal or buildup on the sealing surface. A refill tube pushed down inside the overflow can also create a siphon.

How do you install a Korky fill valve?

Shut off the supply, flush while holding the handle down and sponge out the remaining water before disconnecting the supply line and removing the old valve. With the replacement’s height set and locked, position it at a 45-degree angle from the back of the tank and hand-tighten the mounting nut with its beveled side up. Secure the refill tube with the included clip where that arrangement applies, then reconnect the supply and check for leaks as the tank fills. If you’re installing a fill-valve-and-flapper kit, leave enough chain slack for the flapper to close fully.

How do you install a Korky complete toilet repair kit?

On a conventional two-piece toilet, replacing the flush valve usually means removing the tank, so this is a bigger job than changing a flapper. Shut off the supply and drain the tank before disconnecting it, then support the tank on a padded surface while replacing the flush valve and tank-to-bowl gasket. Tighten the tank hardware evenly and gradually when reassembling; overtightening can crack porcelain. Follow the kit’s fitting instructions and check for leaks both with the tank full and during a flush.

What is the Korky BEEHIVE Max plunger used for?

It’s a toilet plunger for clearing clogs. You get better results with enough bowl water to cover the working end and a firm seal over the outlet. Start with a gentle push to move trapped air without splashing, then plunge while keeping that seal.
