Worked perfectly, didn't even have to disconnect the old one

This turned out to be less than a ten minute repair, mainly because I was replacing the same part that had quit filling the tank properly after 12 years of use. If you are in this same situation, note that as long as the base that connects to the water supply is in good shape (likely), you can just slide the lock ring toward the top of the valve assembly, pull the assembly off the base, and then replace it with the same part from the package. You don't even have to disconnect the water supply, drain the tank, worry about leaks, etc. There are YouTube videos on how to do this if needed.

Works much better than Universal Fluidmaster

Our original fill valve failed pretty early in the life of the toilet by not allowing water to enter the tank without tapping the top of the fill valve. We originally tried replacing with a Universal Fluidmaster 400 equivalent. It worked but was much noisier than the original. So we purchased this unit and saw the difference. They are very similar but this unit has constriction on where the tube is attached. It may also be different near the bottom. With the old valve, it filled quickly but there was less water in the toilet bowl. This new one fills slightly slower and is much quieter and more pleasant than the universal unit. So we now understand why it is better. We hope it will last better than the OEM valve (which we tried cleaning and lubricating to no avail).

Quiet and functional --

The kit contains all the necessary parts for a Koehler OEM install. The clear instructions make a quick and easy install, even for the inexperienced do-it-yourselfer. The fill valve provides a quiet and rapid tank filling, along with plenty of water pressure for each flush. After 6 months of constant use, this product continues to provide quality function in our household.

easy to install, fits perfectly, includes all parts needed

easy installation, works perfect, my original was half great and half black, I picked this one because it looked the same even though they say pick the original color grey or black. Package included everything you need to replace it, even new washers and cups. I would buy it again - this review is real - not item with discounted price for me or such :-)

Buy Kohler parts if you have Kohler.

This part FINALLY fixed our running water in the toilet. We were unable to get the Kohler part locally so we tried a fits-all kit but it would not let the water level rise high enough. Kohler says to be sure to use Kohler parts and they were right in this case. This part got things back to normal. We checked the Kohler site to see which part number we needed then ordered it here and saved a bit on price and shipping.

No Need To Call A Plumber!...

Purchased this item, and watched a "how to" video on YT. Drained the toilet tank.. Took the old part out, put this baby in its place. No problems at all! The kicker is, due to injury, I did this one-handed! So, yes, it's easy! Later, the toilet hissed and ran a bit, due to float valve needing a turn. Turning it solved that immediately. Also, hose had popped out of top of canister in tank, causing bowl to only fill half as much as it's supposed to. Popped hose back in, turned float a tad toward canister, and PRESTO! A full bowl for all! Oh happy day!...

Exact Fit

Fit exactly and was easy to install and adjust the bowl fill flow using the provided flow restrictors. I used this to replace the original valve that came with the Kohler toilet that I bought 3 years ago. The original valve, which was a fluid master 300 and not a kohler, never did fill the bowl completely after flushing. Over time it did a poorer job. It did not have any way to adjust the flow for the bowl filler. Good price too!

Fantastic Buy!!

This is the real deal!! The difference in sound is night and day. Forget the knock-offs that look exactly like this one. They don't perform anything like the real thing. I bought one of the other top of line knock-offs in a home improvement store and it was as loud as the cheapest one on the shelf (had one of those laying around in my plethora of bathroom replacement equipment).

Perfect for Kohler One piece low flow toiltets

For the low flow toilets of Kohler one piece this is a perfect replacement. It installs in about a minute after you get it set up. HAND TIGHTEN only. Never put a wrench on it. You must save your prior fill tube or get a new piece. it does not come with one. The toilet fills quickly. Very easy. Don't pay a plumber $250. You can do it yourself. No tools required. Check the Kohler site to make sure this is the one for you. The generic ones are a few dollars cheaper but you spent a lot of money on the toilet, get the right fill valve.

Worked perfectly for a Kohler Model 3515-04, super easy install

Worked perfectly. I replaced this at the same time I was replacing the flush valve, but it's super simple. 1. Turn the water off down at the valve behind the toilet. 2. Drain the water from the tank (flush first, then either use a wet-dry vac or just scoop it out with a cup and towels)... this is the CLEAN water! 3. Unscrew the plastic nut underneath the tank (may need a pair of pliers to get it started, but can usually do it with your hands) 4. Adjust the new Valve Kit to be the same height as the old one, and the plastic screw for the new float to be roughly the same level as the old one. 5. Swap out the old one (install the new rubber washer on the bottom shaft of the new Valve Kit if it's not already on there) 6. Screw the plastic nut underneath back on. 7. Turn on the water, let the bowl fill up, then test it out! 8. If it doesn't fill up far enough, adjust the plastic screw on the float to raise it up until you get to the right level. Good luck!
