Fix annoying flapper leak once and for all!
Excellent kit! I had been fighting a flapper leak for quite awhile. Save the aggravation, and just put a this kit in. It's easier than you might think! The only modification I had to make was to cut the tube about 3" shorter to fit my toilet. No more leaks!

Quick and easy to install, some modification required
Easy to install and fit will in my Crane toilet. Solved the issue we had with an old leaky flush valve. I did have to trim down the height of the overflow tube by about 3 inches, so just be aware of that if the tank of your toilet is not super tall. Make sure you have a wrench that opens to at least 2.5 inches wide so you can install and properly tighten the nut at the base of the tank as this kit does not provide a tool to assist with that.

installation was fine, but there are a lot of steps
Worked fine (knock wood), no leaks and everything fit my decades-old toilet. I saw one person complain that a problem with the float valve caused a leak and damage; this kit does not include the float valve, so I do not know what that person was talking about. Another person complained about there only being two bolts; yes, that is how many you need. The entire process took me 1.5 hours, including cleaning and having to remove the old, corroded parts. One place in the instructions did not make sense, as it seemed to indicate putting a nut on over a bolt before that bolt goes through a hole. The diagram was more clear. They should also mention that the tank will be wobbly sitting on the gasket to the bowl portion before the nuts to either side get their final crankdown. Sure hope that it lasts, but I am purchasing one for an idential toilet.

Does not fit 2002 Kohler.
The kit is good, but it will not fit my older 2002 Kohler. My toilet needs 3 bolts and a completely different tank gasket. The flush valve itself is good. It seals well and was easy to install. I would recommend, but just know it won't work with Kohler.

Works great, but it's exactly the same as regular
Works great, but it's exactly the same as regular. I thought Performance is some improvement, but it is exactly 1 to 1 as the regular of this company

Very straightforward fix
This repair kit comes with everything you will need to replace the flush valve in your toilet tank. After reading some of the reviews I saw that I may need to cut about an inch or so off the top of the tube for it being a bit too tall once the tank lid is put back on, and this turned out to be the case, so I used a fine-toothed little band saw and took about twenty or so seconds to cut it down a bit. The kit comes with everything you see in the photos, plus all of the tank hardware. I reused the original bolts and nuts already on mine, as well as the flush valve lock ring, so I even had some pieces left over- just in case. Great price, good instructions, this is the best repair kit to purchase if you’re needing to replace your flush valve. Zero leaks, built with sturdy, heavy duty plastic, good, sound rubber gaskets, fits perfectly. Original design, consider it an OE replacement. Buy it! This was an unsolicited and honest review.

Flush valve and seal kit
I like this kit. A very cost effective and quick fix. I like to have a kit like this with a new fill valve as spares. I have rental property and my own home. I usually throw these kits in a rental property between new tenants so I don't get called for any toilet issues at 2 AM. Once you understand how a toilet works it's pretty simple. Over the years I've learned if the toilet starts to have an issue I don't just usually chase one part I replace all the parts at one time. Its like $30 in parts and 30 minutes to an hour labor and you should be good for at least a few years. I usually put the toilet tank lid in the shower so it won't get damaged. Flush the toilet to empty the tank as best you can. Turn your water supply line off at the wall and then remove the tank screws off each side. Then I will unscrew the water supply line from the tank last and gently tilt the tank to the opposite side to not leak the water on the floor (since you unscrewed thexsupply line) then I empty the remaining water from the tank into a sink. From there, then just replace the parts per the instructions. Consider having a green scrub pad and some CLR if toiler cleanser won't remove all the stains. The toilet can look near new when you're done. You got this. Plus there's you tube university out there if you need it. :-) Take care

Only contains 2 sets of bolts and not your standard 3 sets.
It would great if it came with 3 sets of bolts/gaskets/washers. It only comes with 2 sets. Most toilet tanks attach to the top of the bowl using 3 bolts....not just 2. I had to go out and buy a whole set at the local hardware store since I needed that third set of hardware. This is just unacceptable to not include hardware for 3 sets of bolts/washers/gaskets.

Bonne qualité
Fonctionne à merveille, remplacement facile, qualité, pas necessaire mais personnellement j'aime utiliser du lubrifiant à la sillicone/plombier (jamais autre chose) sur les caoutchoucs pour un meilleur glissement d'assemblage et durabilité
