How to Install 528X Korky 2X Long Life Toilet Fill Valve Kit by Korky

Hello and welcome to Korky Toilet Repair. Today we’re going to install your new Korky 2X fill valve. The first step is to shut off the water supply to your toilet. Next, hold the handle down to drain the excess water. Sponge out the remaining water in your toilet tank. Place a bucket underneath your tank to catch any excess water. Disconnect the water supply line and removing the mounting nut. Remove the old fill valve.

Turn the top of your new fill valve counterclockwise and pull up to fully extend. Place the valve in the tank and press down until the corner of the black over aligns with the top of the flush valve.

Lock the fill valve in place by twisting the upper half clockwise. Make sure the rib on the top of the valve lines up with the pegs on the bottom half. Place the locked valve in the tank. Screw on the mounting nut.

Insert the metal clip into the refill tube and then attach the clip to the flush valve. Make sure the refill tube has a direct path to the fill valve. Trim the tube if needed and then attach to the fill valve.

Reattach the water supply line. Turn the refill adjuster clockwise to the fully open position. Turn the water supply on and wait for the tank to fill completely.

Wait 2 minutes for the water in the bowl to settle. The excess water will drain out. Mark the water level in the bowl with a pencil or dry erase marker. Flush. If the bowl water level reaches the mark before the tank is done filling, turn the dial counterclockwise to reduce flow. If the bowl water level is below the mark once the tank is done filling, turn the dial clockwise to increase flow. Repeat this process until the bowl water level reaches the mark at the same time the tank finishes filling.

Congratulations! You have successfully installed your new Korky 2X fill valve.

I installed one of these today to replace an old ball system. It's quick and easy to install with pretty clear instructions. I found you on YouTube because there was one minor point I wanted to be sure of and you covered it! Thanks!

I installed this and found that the bowl fills to the correct level without requiring the hose to be pointed into the overflow tube at all. So, I point the hose into the tank and turn on the valve full. I assume the tank might fill faster that way. Is this ok?

I would love a video on how to install the bowl filltube to a kohler 3 inch column type flush valve. Your replacement tube is too big and I have to modify the tube to make it fit. Is there an adapter?

I recently replaced our toilet's fill valve with this Korky product. Installation seemed to be straightforward, but once a week or so part of the tubing, either where it's attached to the valve head or where it's attached to the "fill tube" (?) pops loose and water spews out of our tank, soaking the bathroom. I installed per instructions -- do you have any advice to resolve this issue? 🤔

Just curious: what happens if the fill valve is installed too high or too low (the corner is higher or lower than the top of the overflow tube)?

I installed one of these a few years ago and now the assembly is hissing. I bought a full valve cap but I don’t think that works with this. How do I fix it?

There is no guide on how to clean this specific model: 528x.
