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

Silent, Simple, and Solid Upgrade for Any Toilet This 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.

Excellent, simple desgn,simple install. Works perfectly & MADE IN THE USA! Cant comment on longevity yet but function is great so far

I haven't replaced a toilet fill valve in many years, but I remember the last one being troublesome since it was a different brand and model from the original in the toilet tank. This Korky is wonderful, however - very simple and straightforward instructions and then it operates more quietly and very reliably so far - if that changes I'll be back to edit the review. Replacing this yourself will save you anywhere from $125-300 for the labor. If you think you can't do it or are afraid of plumbing issues - I get it, I don't like water seeking any unsealed gap and causing leaks - ask a handy friend to help. Removing the old fill valve is pretty easy, the only issue I had was that the water 'pipe' in the toilet to which the flap is secured at the bottom and where the rubber/plastic tube is clipped at the top for filling that pipe (which then fills the tank) had a round plastic piece at the top shaped like the 'theta' symbol. I wondered if it was permanently connected to the pipe, but gently wiggled it with cloth-covered pliers and it came off easily allowing me to clip the water tube from the fill valve where it appropriately connects. The other tip is to make sure the 'line' marked on the fill valve is 1/2" below the top of that water intake pipe where the fill valve plastic tube connects. I had to cut off about 1" of the plastic tube since it was too long for the distance between the fill valve connection and the water intake pipe. All in all it took about 1 hour since I haven't done it often. I really appreciate that it's made in the USA and gets fantastic reviews.

I actually haven't had to install this valve yet, although I think it has been almost a year since I ordered it. The previous valve -- also a KORKY -- seems to be holding up, so we're getting as much use out of it as we can. It had started doing this weird thing where it would hiss multiple times after flushing, but when I went to replace it, I found that whoever had installed it previously (possibly me, as my husband is useless as far as DIY) had NOT turned the water supply on IN FULL, so that seemed to help the tank fill properly and the valve started working more normally. When I tried to return the new valve to Amazon because I didn't need it, I was told I could keep it, but they gave me a refund, which was nice (it was only about $8, but still....). Unfortunately, NOW the older valve IS beginning to act up again, so I'm actually glad Amazon didn't make me send it back, because it might actually need it now. Based on my past experience, however, these KORKY valves are easy to install, as long as you know what you're doing, and remember to turn the water supply OFF and empty the tank before removing the old valve.... The height of the valve can be adjusted to fit different tanks, so it's versatile for many brands of tanks. It WOULD be great if they would last longer, but some of them don't.

Installation took less than 10 minutes. The flow and fill up is quick and quiet. 10/10

This toilet valve is a huge improvement to the older style. Water level adjustment is quick and easy. Once installed just twist it counter clockwise a 1/4 turn and raise or lower it where you want and twist it back to lock in place.

If you can wait and save a trip use Amazon

Installed in 15 min. No issues fills fast.

Very very good products this fill valve and original. I liked this fill valve every month minimum 2pcs order my company

Overall, I am happy with the product. I had the old ball style fill valve that after flushing, would take a long time to fill and was noisy. I decided to give this one a try after reading reviews online. The install itself was easy. Just make sure to get all the water out of the tank or have a towel/bucket for when the water drains out. The instructions were straight forward. Now when I flush, it's not as loud as before, but I was expecting it to be more quiet than it is. The good thing though is that it doesn't take long to fill the tank so the noise is very short. I'm happy with this purchase. It wasn't expensive and was easy to install.

Excelente producto; facil de instalar y de buena calidad, sigan las instrucciones al pie de la letra. Ademas es una valvula de muy buen precio que reemplaza a las de marca Toto que son mucho mas caras. Lo recomiendo ampliamente

Quality of product is good but of no use as its inlet dia is neither 1/2” nor 3/4” thats why unable to connect to water supply .. dis product should be removed from amazon as it’s useless for indian users….

It’s good and silent, however ,inlet pipe size deferent in USA mm in UAE inch . The specification shows it 1/2 inch but it’s not.
