Korky QuietFILL 2X Long Life Toilet Fill Valve - Universal Fits 99% of Toilets - Easy Height Adjust for Fast Install, 528X

"Perfect for Septic Systems: No More Wasted Water or Worry!"Living on a septic system, even a small trickle can cause big issues over time. Our old fill valve had a persistent micro-leak on two separate toilets, wasting water and adding stress to our system. Adjusting the height or other components didn’t help.This Korky QuietFILL came to the rescue! It installed easily with no leaks, and it works like a charm. Korky really has this figured out—I've never had issues with their products. While everything is meant to be "hand-tight," I found channel locks helpful for loosening and securing without over-tightening. A must-have fix for older toilets and septic-conscious homes!

Great product! Installs easy and worked great but it isn't much quieter than the old one it replaced though. The only thing I had different with my installation was that I have a Mansfield toilet and the instructions said to insert the fill tube one half inch into the stop cap. The only problem was the fill tube was too big to fit in the stop cap and I had to drill out the stop cap so the fill tube would fit. Everything else went great! The absolute awesome thing about this fill valve is the fact that it got rid of the old ballcock and rod that you had to bend to change the water level. Now you just turn the fill valve counterclockwise and pull up or push down then turn back clockwise to lock it to change the water level in the tank. Awesome product I will definitely recommend it. I'm super happy with it!

I decided to replace my Kohler refill valves because i got tired of replacing the rubber seal under the red cap and because the level adjustment is a pain, getting harder to adjust year after year as calcareous deposits make it more and more difficult to turn the rod.Very pleased with the install, which took 3 minutes start to finish. The refill adjustment is very easy to set correctly the first time, unlike that of Kohler refill valves. (On the other hand, the Kohler can be adjusted in place without getting your hands wet, something that's harder to accomplish with this one -- we'll see how soon it will need re-adjusting.) Functions perfectly so farAs a bonus, it offers a straightforward adjustment of the water level in the bowl, something that's harder to do (and not documented) with the Kohler valve.Highly recommended, pending some feeling for lifespan.

I bought this to replace the old ball float on an arm in our 20 year old Mansfield toilet. Easy to install. It is louder than the old fill valve, but is does fill the tank much faster. Amazon price was less than the Ace hardware store.

I replaced the standard Korky fill valve that was originally in our toilet with one of these QuietFill versions and it works as expected, no crazy change in overall functionality. The speed of the tank refill seems to be the only downside as it is a tad slower than before, but I think that’s just the trade-off for the lowered noise of this unit compared to the regular fill valves. It was very easy to replace, pretty standard fit if you already use a similar fill valve or the size matches your OEM valve. Assuming this lasts longer than the original one, these are a solid value as I don’t typically need to replace these often as Korky tends to be pretty good quality in general.

Great instructions for installation. Took minutes. Fixed my "ghost flush" problem. A little noise at start of flush, then quiet and a quick fill. I will be buying more for the other toilets.

This was an exact replacement for my previous fill valve that lasted me for YEARS! Removed the old one, replaced it with this one, made the necessary adjustment for height and restarted the water flow and all was right with the world! One caution: this new model also has a flow adjustment, which I needed to play with because when set too high the water would spurt and splash. A simple lowering of the dial and everything was perfect.

Easy to install
