Fluidmaster 507AK PerforMAX Universal High Performance 2-Inch Toilet Flush Valve Repair Kit with Gasket and Bolts

Easy to install and works as expected

Quick installation, great instructions and good quality materials. No more occasional leak or refilling issues. Great product.

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.

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

This product has a slightly maybe 1/4" smaller throat and guided flapper. It appears it will be more reliable plus also work better with standard flappers (due to the smaller throat). The "standard throat* has the larger hole that will tend to swallow the flapper over time and leak sooner. Note the old brass product back in the day had a smaller throat and worked great but it seems they went to the larger size in the 70s when they switched to platic (maybe done inadvertantly to save plastic). So this one is a step in the right direction (and yes still plenty of water flow for my Toto). The adjustable overflow height is probably a good feature for some but I'd prefer it had a solid overflow tube i could cut off to height, but you can't have everything. I will buy again.
