## Questions & Answers

**Q: Does the Korky 818BP match up/replace the Kohler 85406 flush valve?**
A: According to Korky's website: "It has a universal design to fit all brands and features a wide range of adjustability to fit most 2-piece and 1-piece toilets. Designed to fit more toilets, the QuietFill toilet fill valve adjusts from 7-3/4 inch to 13-1/2 inch."

**Q: if this is a prime item, why is the delivery date a month away?**
A: Go to Lowes or Home depot...in stock and grab a Starbucks double express :-) on the way...

**Q: When I connect to the water supply line, the connection is loose, and water leaks out. Is the connection point on the Korky supposed to be empty?**
A: The red gasket at the bottom should be inside the tank, the large nut is then installed hand tight and then snugged a bit more but not too tight.  if you do this, there is no way that water can leak out of the tank at that point, unless the tank is cracked.

**Q: Is this fill valve by Korky superior to that of Fluidmaster (as in durability and preveting toilet leak)?**
A: The valves we were sent did NOT have the gasket on the bottom included. Was not noticed at first, why would we think it didn’t have needed parts. Put in and leaked everywhere!  Finally figured out why. So just be aware of that.

### ⭐⭐⭐⭐⭐ Silent, Simple, and Solid Upgrade for Any Toilet
*by R***S on August 29, 2025*

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.

### ⭐⭐⭐⭐⭐ Best on market in my opinion
*by A***R on July 22, 2025*

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.

### ⭐⭐⭐⭐⭐ Goodbye Float Arm Mayhem, Hello Quiet Flush Zen!
*by G***N on July 28, 2025*

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!
