K-400H-039 High Performance Toilet Fill Valve with 2-Inch Adjustable Toilet Flapper Kit

Fluidmaster has been around forever. My go-to valve; beats Korky and almost always cheaper than OEM (Am Std for example). Fits, works, no tool install usually. They last about 5 years. Amazon usually has them for a few bucks less than the local hardware or big box.

Worked like a champ. Easy to install and dial in without a youtube video even lol. Saw another reviewer mentioning the flapper didn’t fit because he bought a 3” and needed a 2” but didn’t know where to measure. Well, logic would dictate it being the hole it’s plugging, right? Perhaps? Just maybe? Just lift the flapper, eyeball the opening it was plugging. If it’s the size of an Oreo, you got a 2”. A baseball, you got a 3”. If your toilet was made after 2000, it could be a 3”. But before 2000, more than likely a 2”. If you’re uncertain, they make versions of this item without the flapper and you can purchase that part separately or as needed. As for measuring it? Use the ruler app on your phone to estimate without sticking a tape measure in your refill container. (Wink). That said, the flush is much stronger now, there were no leaking after install. The build quality seems fine, and these are inexpensive enough to not expect decades of use. My only complaint is the plastic or rubber tube to connect the water was a bit shorter than my previous one and interfered with the flush lever, so I had to use my previous one which was fine. I mentioned that specifically because some users described having to cut the included tube to make it shorter. In my case the reverse was true and mine was too short. Pause. All in all, a simple, inexpensive fix and I think I’ll replace the others in my house as well so they can race to see which lasts longest. Lol. 10/10 would recommend.

Excellent product at a good price. I installed it and works fine. Very good instructions. These last a long time.

Easy to install and works perfectly. The flapper didn't fit our toilet but the other part is a perfect fit and works as it should. We do not notice any "loud noise" and it seems durable.

the bog was getting a bit noisy from water starting to run. this was the perfect solve. easy to install, adjustable and I don't think I'd use any other brand.

Easy to install and works perfectly

I know nothing about plumbing, so when I had to replace my fill valve, I nearly panicked. When I received this order, I let it sit for a month before watching videos that made it look super easy. After a second month went by, I finally tried the install. This was stupid easy to install! The more complicated steps was setting the water level once it's in and working. Everything needed to replace everything in the tank comes with this item. And everything feels super durable (my last flapper literally dissolved. And, it's much quieter than the valve that was only a few years old.

Well, I'm totally impressed & can't believe how easy it was to install! So our ancient floatie finally just quit on us the other day! Figured I was in for a part that would cost an arm & a leg! I mean it's plumbing you know! Well to my very pleasant surprise not only did we update our toilet, but it was less than $20! Sure I read reviews, researched and this is what hubby said this would fix it! So not only did I receive it in super fast delivery time, (practically next day)it actually WORKS! ONLY took around 15 mins to install and no flooding either lol! Directions were awesome and we are still getting used to how QUIET it is! I've flushed twice thinking I forgot nope I didn't hear it! We are very pleased with this update and realize how important everyone's experience is for others! Very easy to adjust, didn't take much it was almost perfect! The reasons I purchased this one, great reviews, sold ALOT OF them in past month, reputable brand! Easy peazy decision! Definitely worth every penny! Hope this helps someone to purchase this! It's amazing! Very highly recommended!
