Fluidmaster K-400H-039 PerforMAX Toilet Fill Valve and 2" Flapper Repair Kit, Plastic, 1-Pack, Height 13.9in

I was worried to attempt to fix a toilet by myself, but tired of waiting on a man to do it for me, I ordered this it. I watched the YouTube video that the package directed me to, and followed the easy steps. Boom….my toilet flushes and it no longer runs endlessly. I am excited for the other toilets in my house to break so I can order this again. Five stars.

Fluidmaster is the Gold Standard for Toilet Tank fill Valves. So glad Walmart had this in stock. A friend of mine had moved into a new place and it needed a new one of these. I ordered it on Walmart com and picked it up from the store. Very Pleased it works wonderfully.

I have had this type of valve for many years which makes the installation of the working parts very simple. I just turned off the supply valve at the wall,drained the tank. Released the clamp on the old valve,slid it up and off and slid the new valve down on the stem, locked it in place with the ring and adjusted it to match the old one. Always replace the rubber flapper as it snaps in place and finish the job. I keep the stem and seal in case it might need to be replaced but so far it has been years since I put the first one in.

Was having an issue in the toilet not flushing right. Googled some fix options. It was cheaper to buy this kit than the items separately. Plus I had other pieces left over in case needed next time I have issues. Fit was fine, pretty easy to install. I didn't even bug the hubby.

The toilet valve my landlord's maintenance guy installed... wasn't the best. I was leery of trying to install one myself, but I figured I'd give it a shot. This thing had great instructions, easy to install, and had three different adjustment areas to make the water come up just right. Heck, installation took under a half hour.

It's working perfectly! I had a faulty one and needed to replace it. Toilet plumbing work isn't fun but this was a fairly easy install, definitely doing its job. This brand was highly recommended from my friend that said they last a very long time, perfect!

It fixed the problem perfectly, the old stand valve was completely clogged with mineral sediment- I could have painstakenly repaired it but instead I just replaced it with the one I bought on line - also I did not use the flapper as mine was ok. I really only needed the stand valve, I just kept the flapper for a spare.

I have never before done any toilet repair but with this replacement part, I was able to easily fix the “ ghost flush” that was waisting a LOT of water. The instructions were 100% easy to understand and follow. No tools needed and all the parts were included.

This kit is a lifesaver if you have a noisy or slow-filling toilet. It combines the Fluidmaster PerforMAX Fill Valve and 2" Flapper Kit, which is basically their "high-performance" line. The big win here is the adjustable water-saving dial, which lets you control how much water goes into the bowl with every flush. It's also built to be universal, meaning it should fit most standard 2-inch flush valve toilets. The installation is pretty straightforward, and many people find that it fixes common "phantom flushing" or leaking issues instantly. ​There are a few things to keep in mind for the install. On the plus side, the height is adjustable, so it fits well in both taller and shorter tanks. The flapper is also made of a chlorine-resistant material, which is great if you use those drop-in tank cleaner tablets that usually eat through rubber. However, some users have noted that the water-saving dial can be a bit finicky to tune just right at first. Also, while it's marketed as quiet, it might still have a noticeable "hiss" depending on your home's water pressure. Overall, it's a solid, heavy-duty upgrade over the basic valves you'd find in a standard hardware store.

The Fluidmaster flapper repair kit worked well and stopped the leak immediately. The Instructions were clear and easy to follow, making installation quick even for a beginner. After installing, the toilet flush was smooth and consistent with no more running water. The flapper had a good fit change compared to the old one, sealing better and improving overall performance. Overall, a solid and affordable fix.
