Korky QuietFILL Toilet Fill Valve - Universal Fits 99% of Toilets - Easy Height Adjust for Fast Install, 528

Silent, Simple, and Solid Upgrade for Any ToiletThis Korky QuietFILL toilet fill valve really lives up to its name. Installation was straightforward—about ten minutes with just a pair of pliers—and the adjustable height made it fit my older toilet without any fuss. The instructions were clear, but honestly, the design is so intuitive that you barely need them.The biggest upgrade over my old valve is how quiet it runs. Gone is the constant rushing noise after every flush; instead, it fills quickly and with just a soft hum. I also appreciate that it shuts off cleanly with no hissing or trickling afterward, which I had with the worn-out valve it replaced.The build feels sturdy, not flimsy like some generic valves. It also comes with a twist-lock height adjuster that makes fine-tuning easy without disassembling the whole thing. I tested it on a couple of toilets around the house, and true to the claim, it really does fit nearly all standard models.Something to keep in mind: if you have very hard water, sediment can eventually clog any fill valve, so it’s worth cleaning the seal occasionally. But this one seems designed to handle that better than most, and replacement seals are inexpensive if ever needed.Bottom line: A quiet, reliable, and easy-to-install fix that makes an old toilet feel brand new. One of those small home upgrades that pays off immediately in everyday use.

Easy install, quiet and quick fill. I’ve used the other leading toilet valves for years. I decided to try this one and now want to replace the valves in all my toilets. This is quieter, cheaper, and works flawlessly so far.

I went all in and installed the Korky QuietFILL Toilet Fill Valve in every single one of the six toilets in my house. Yes, six. Because who doesn’t want a coordinated flush party? From the moment I popped these babies in, my life changed—for the better, and way quieter.First off, the install was so easy it practically did itself. The adjustable height meant I wasn’t playing the “Will it fit?” guessing game. It fit perfectly every time, like it was custom-made for my tanks (which it basically is, since it fits 99% of toilets).Now for the best part: the peace and quiet. Gone are the days of those giant, clunky float arms thrashing around in the tank like they’re auditioning for a percussion band. No more weird noises or unexpected splash concerts. Just a smooth, quiet fill that feels almost fancy. I swear, my toilets now flush with more style than I do in the morning (and that’s saying something).If you’re tired of your toilet tanks sounding like a washing machine on spin cycle, do yourself a favor and grab the Korky QuietFILL. It’s fast to install, fits like a glove, and will have your bathroom feeling like a spa instead of a noisy construction site. Six toilets down, zero regrets. Flush on, my friends!

Good price with simple install. The main thing to note compared to the standard Fluidmasters is that the fill level is completed controlled by the initial height adjustment in the bowel. Follow instructions to set the height and get the desired fill level. Once you get the height adjusted it works reliably with a quick fill and reliable shutoff. I have not had a Korky long enough to comment on long term reliability.

Easy to install, fills toilet in about a minute. Quality is great and can adjust to save water. Very sleek design, and functions like it should. Very good price!

Toilet was making loud whistle sound with every flush. A plumber friend recommended this item and it completely fixed the sound. Just make sure your water is off, and install. Very easy and so much cheaper than expected. This unit fit standard two piece toilet. Seems durable!

After many years, the original fill-valve failed on my Niagra Stealth vacuum assisted toilet. I was worried that this new-style fill-valve wouldn't fit into the relatively small space available alongside the flushing mechanism. It does fit. I had to unlock the white-covered float valve by twisting it all the way to the right when I installed it using the hand-tight nut. Then after installation when I locked the white float-valve (by twisting it left at the proper fill-height), it locked into place with just barely enough clearance before hitting the side of the tank, as can be seen in my photo. (NOTE: If you need to adjust the float height after installation, be sure to shut off the water first!) I added the tube using the included stainless steel clip. Everything is working well. Before and after photos attached.We'll see how long it lasts, but for now I'm giving it 5-stars. I'll likely revise this review if it doesn't last several years.

This water valve works great. Very easy installation. Works well and doesn't leak. I would highly recommend this product.
