Installed this flapper and yet it is still leaking. What is wrong? Why does it say it is a 2in. flapper but the width is 3in?

Answer: 
Check to see if the part of the tank that the flapper rests on is smooth and flat. The flapper can handle small irregularities but not more. If it didn't leak in the past you may have lime buildup that could be removed with vinegar or CLR

Answer: 
Have you tried to clean around the drain hole? That may be causing leakage. You might also need to replace the drain tube itself. The two inches is referring to the amount of space on the flapper that attached around the drain tube. You don't measure the width of the whole unit just the part that kind of looks like prongs.

Answer: 
This flapper should fit any tank. Sometimes there is residue/buildup on the tank to bowl gasket, usually round black/red ring in toilet tank, where the flapper touches to seal it. This buildup can cause a weak seal and it will leak. Turn off water supply. Flush toilet to empty water from tank. Take a nylon or other kitchen dish scrubber and scrub the gasket, especially the top of it, to clean the residue Read More

Answer: 
I think you need to clean your valve seat. Don't think the problem is with the Korky. Drain the tank then take a paper towel with a few drops of Dawn detergent and wipe/dry thoroughly. That should solve your problem.

Answer: 
Usually it is because the chain is not loose enough or the seat that the flapper goes against is a little rough. I have never had a new one to leak.

Answer: 
Did you clean the mating surface in the tank? Usually no seal can be made with a gunked up surface.
You may have more issues like a leaky intake valve system or your tank ball water level is set to high not allowing a proper incoming water shutoff.
Width is the wrong measurement it is ID not OD.

Answer: 
You have to get the chain/handle assembly adjusted correctly. To make sure you have the right flapper, I'd disconnect the chain and see if it seals the hole properly on its own. Then I'd connect the chain and make sure to leave a little slack for the flapper to flop down properly.
If that doesn't work (and you have the right flapper), maybe there's something around the hole that is holding the flapper Read More

If that doesn't work (and you have the right flapper), maybe there's something around the hole that is holding the flapper from properly sealing? You can move your finger over the opening and see if something is impeding the flapper from closing off the opening.
Other than that, I don't really know. These work on a fairly standard basis, meaning there's not much to them. If all else fails, I might purchase and install a new one (or return the bad one - maybe yours is faulty somehow?) - or perhaps install the old one again and see if the problem is the same. Hopefully this job won't require a plumber. I'd hate to see you have to fork over plumber fees for a job like this. Read Less

You say it is still leaking, but are you sure it is water getting from the tank down the passage? If so, did you thoroughly clean and inspect the valve seating area prior to installing this flapper? If not, do so since there may be something wrong with the seating area preventing a good seal. I did notice when installing mine that the top of the seating area, between the arms that are the attachment points, had to bend a little to allow the flapper to sit down correctly onto the seating area. It is possible that yours is doing this as well and the angle it is bending at is causing the flapper to not seat correctly.
What make/model is your toilet? It might not work with this flapper, even though it is listed as Universal. Have you contacted Korky about this to see if there is a known issue with your toilet model? Read Less

Answer: 
Check the diameter of drain pipe. You might need the larger flapper. It is the bottom part that is 2 inches.

Rated 4.5 out of 5 by 66 reviewers.
Rated 5.0 out of 5.0 by Solid option for toilet leaks If you are here - your toilet developed a leak and you need to fix it. More often then not the flapper becomes a source of a leak for one reason or another. This korky provides a rather universal flapper option with different options to slow/increase the time it takes for the flapper to close. The back of the box even calls out a few configuration for common toilets. Its the only one I have seen capable of this functionality, which does indeed make it more universal because not all 2 inch holes empty at the same speed. So you can dial in how fast it drops and seals up. I've tried other flappers only to have them give up after a few months. Other don't work at all causing you to curse at a toilet bowl... such a good use of time... This one is replacing a retro-fit watersaving toilet flapping system that developed a leak. June 17, 2016
Rated 5.0 out of 5.0 by good product The water saver is easy to install and if your toilet isn't listed in the package you can go on the web site and watch a short video on how to adjust and install the flap real simple and seems to work just fine.The only thing I had to do is change the hook for the handle because their's wouldn't fit but that also was no big deal either. If you want to save some water this is an easy fix. June 18, 2016
Rated 2.0 out of 5.0 by Flapper Flopper This part, while well made of a material whose flexibility portends the ability to seal well, is not the "universal" fit it is advertised as. When installed (which is accomplished readily) two key failings were noted: Failure to seal against the seat into which it is fitted, resulting in a constant flow of water; and, the flexibility of the flapper material makes it difficult to keep it secure on the pivot shafts. For info, this was being installed on a 50+ year old Eljer (although the existing flapper valve/seat was an after market replacement from many years ago), and fit and function on newer water closets may be better. To be sure, measure the spacing of the pivot shafts before purchasing. The means to adjust the amount of flush water is provided via two rotating parts of the valve which admits more or less water into the "bowl" making the valve seat faster, to reduce the flush volume used. The flush time with both openings closed (no water admitted) seemed to work, however, as noted above, the flapper itself failed to seal against the seat. The instructions recommend installing the chain with minimum slack. When so installed, a single depressing of the flush handle results in an acceptable flush....however, if you happen to depress the flush handle when the tank has already partially emptied, with minimum slack in the chain the flapper, due to its flexibility, has a tendency to go over center ("belly up") has to be positioned manually.

Rated 5.0 out of 5.0 by You get what you pay for I wanted to just replace the flapper in my toilet tank, but was afraid I would need the entire kit. None of the rest of the components looked bad, so I thought I'd just try a new flapper...and Home Depot has an easy half dozen choices...nothing's easy. There were 3-4 cheaper than this one, and this one isn't expensive. But I bought this one because it is adjustable. It works perfectly. Buy it and spend a minute and 32 seconds installing it! That includes turning off the water! :) July 26, 2016
Rated 5.0 out of 5.0 by Good product Good product, installation instructions were clear, I like it! August 23, 2016
Rated 3.0 out of 5.0 by Not my preference This could be some user error and some personal preference speaking, but I could not get one of the parts to adjust (the one that spins around the flapper) and the "low flow" design that requires you to hold the lever down for a long time to get the toilet to flush thoroughly is not my preference. Again, the adjustment problem could be user error and the "low flow" frustration could just be personal preference, but I did not prefer this style of flapper. August 17, 2016
Rated 5.0 out of 5.0 by Wrong part. Had to return. Good price though and easy to install. I purchased two different kinds and this one was the wrong kind so I had to return it. The employee recommend I get two different types in case one didn't fit. If I got the wrong one then I had to come right back and that would take time. If I got both then I could return the wrong one at my leisure. I did as he suggested. It was a smart decision. The one I wanted didn't fit. When I did take it back it was a totally hassle free experience. July 12, 2016
Rated 5.0 out of 5.0 by Easy to install, No leaks, Still kept strong flush even though water level is lower Before the flapper was installed, I marked the original water line with the toilet filled (the "WL" line) and when emptied with the water off (the "M" line). After removing the old flapper, the korky flapper was easy to install. Since the water line didn't reach within the 1/2" threshold of line "M", I had to adjust the white band and repeat the process in steps 4 and 5; the water level fell within the 1/2" threshold of the "M" line and the installation was done. I also noticed the new "WL" line was also lower than the original "WL" line and flushing capacity hadn't changed either. November 12, 2015
