    • Easy to install, seals, no leaks
Size: 1 Count (Pack of 1)
Extremely easy to install. Didn’t even need to close the toilet valve. Slipped off one side of the old flap and moved it over slightly as I put on one side of the new flap. Did the same with the other side and it was on. I counted the number of loops in the chain of the existing old flapper so the length would match up. Removed the old chain and clipped on the new. Amazed. First time doing this. The best part was it works. Only suggestion is make sure you buy the correct size flapper comes in 2” and 3” and read the back of the package to turn the dial to the correct air hole for your toilet as instructed. ... show more

    • Awesome, super easy
Size: 1 Count (Pack of 1)
Review Image by Christina Li
Super quick install (minutes). Fits Kohler k-4620 perfectly. Instructions for settings are perfect. The Band setting, white circle is open, the black circle is closed (I missed that on the chart). Made in USA. Loved other Korky products (fill valves), and decided to try the 2x lasting for just a few dollars more. Time will tell, 10 year warranty (!) Edit: Weird to rave about a toilet flapper, but this is the best flapper in the house. The water saving feature setting works perfectly without needing a second flush. When other flappers go bad, I will be replacing with Korky! ... show more

    • The Best
Size: 1 Count (Pack of 1)
I have tried a lot of brands - Fluidmaster etc. and only the Korky brand works consistently and durably. Period. Excellent product. Others seemed to work but after a few days were leaking. Korky is worth every penny. This is not a paid endorsement.

    • Worth the extra cost…
Size: 1 Count (Pack of 1)
You need to make two simple adjustments on this higher priced product. Unfortunately, I only made one and I constantly got “double flushes” until I found the second adjustment, then it worked perfectly. I needed to change the adjustment from a closed to an opened hole. The other adjustment was a “6” for my American Standard toilet. I recommend watching the Korky install video on You Tube. It’s not complicated, but the hole adjustment can be overlooked because it is the same color as the rest of the flapper. I purchased this higher priced one because it is guaranteed to last longer. When my old basic Korky model failed, my water bill increased by $80 for the month. The toilet was a guest unit that is rarely used. ... show more

    • Perfect fit to stop the slow leak.
Size: 1 Count (Pack of 1)
This did a great job in stopping a slow leak on our toilet bowl. Like the fact that it has adjustments that can be made which helps the device in creating a seal. I would not buy any other very well designed and super easy to install. Perfect fit and worth every penny.
