Q:My toilet is an old one, I’m 72 and don’t know much about that stuff. I was looking for a toilet flapper and you have a 2 in. And 3 in. Is there a high performance one that will fit
by|Oct 31, 2023
1 Answer
Answer This Question

A:  The Korky Ultra 2X flapper is compatible with flush valves that have 2" drain openings. The Korky 3" Premium Universal Flapper (P/N: 3060CM) is the best choice for flush valves with 3" drain openings. 3" flush valves became popular within the past 20 years, so if your toilet is more than 20 years old, it likely requires a 2" flapper.

          In order to make this "fit" all brands, you must adjust 2 dials on the underside of the flapper through trail & error. This is not shown on the outside of the package but on the installation instructions hidden in the package. To get the correct adjustment requires, turning off water, draining tank, installing, letting tank fill and waiting. After 3 attempts, wasting several gallons of water, I could not get the correct adjustment and keep it from leaking. I gave up. Returning this one. Cleaned my old flapper and reinstalled it. It's working great. Didn't need a new one after all.

          Easy flapper replacement for decade+old toilet
          Decades old toilet flapper was leaking leading to auto-flushing, so I knew it was time to replace the flapper. This 2x Korky model goes over the top to fit older and newer toilets with an adjustable fill ring, but thankfully, I didn't need to adjust it for my old toilet. Install was simply unclipping the two sides of the old flapper, then slipping the Korky on. No need to turn off the water supply on my toilet, and the uninstall and install took less than 20 seconds. Clip the chain on & done!

              I spent extra to purchase this item. However, I searched but could not find instructions outlining the use of the "dial" on the underside of the flapper. Further, I had considerable trouble trying to keep the chain from becoming 'hung' under the edge of the flapper. See my photos and the narrative. I spent considerable time trying to solve the problem. Photo shows how I solved the problem.

              Thanks for taking the time to write a review. From your pictures posted, it appears as though the flapper is installed incorrectly on the flush valve. The back flapper arm should be connected to the flush valve like the front one is. Additionally, we recommend using only one chain to connect your flapper to the tank lever. It appears as though two are currently being used. Are you able to contact our customer service team? We would love the opportunity to get your flapper installed correctly. Your flapper is backed by a 10 year warranty and we want to ensure your 100% satisfaction. Please call 1-800-528-3553 to speak with our team.

              Be careful when you need to replace the toilet flapper. Just because it says it will fit a 2 inch opening doesn't mean that it will work in your toilet. As you can see from the photo I REALLY needed a new toilet flapper, and I had 2 inch opening, BUT.......I spent over ten minutes trying to get this flapper to fit and seal properly. I finally gave up realizing it just wouldn't work. I ended up going to the hardware store and getting a flapper that looked EXACTLY like my old flapper. In less than a minute I had the hardware store flapper installed and working properly. It's too bad this Ultra High Performance Flapper didn't work because it has a nice long 10 year warranty.

              We are sorry to hear that this flapper didn’t work with your toilet. Unfortunately, the flapper you are trying to replace is a Kohler shark fin flapper. Your Kohler toilet requires a specific fit flapper. Would you be willing to contact our customer service team? If you have additional questions or feedback, please dial 1-800-528-3553 or email us at sales@lavelle.com. We are available Monday through Friday, 7:30 AM to 5:00 PM CST.

              Don't let the settings alarm you.
              Not all flappers are created equal. I found this out with my prior flapper that used a plastic chain. Although it served us well for a while, the chain did snap. I was able to use the extra links to resolve the problem but a few weeks later, it broke again twice in one day. Long-story-short, when buying a flapper, look for one with a metal chain. The Korky, universal flapper comes with a metal chain and fits all standard 2” toilet tank drains. You will need a small, set of pliers to pry open one of the links so as to attach the chain to the flapper. An included clip fastens the other end of the chain to the toilet’s handle rod. Be sure to leave any extra links at the top of the chain so that they don’t interfere with the flapper sealing off the drain. The unique feature of this flapper is its adjustable band and dial settings for closing the flapper. The band can be set to open or closed and the dial has settings from 1 to 6. With your existing flapper in place, you simply shut off the water to the tank, flush and mark the low-water level on the inside of your toilet tank with a pencil. Then, change to the new flapper, fill the tank and flush again. Look to see if the flapper closes within ½ an inch of the pencil mark. If not, then try changing the band and / or dial settings as directed in the installation instructions. The back of the package lists the band and dial settings for some popular toilet models. Mine, a Gerber 28-790 was not listed but the flapper closed right at the low-water pencil mark using the factory-default settings. (dial closed – band setting 6) Don’t be alarmed that all of this sounds far too complex for a toilet flapper; it really isn’t. The flapper was installed within minutes and works as expected. The settings simple increase the probability of this flapper working correctly in your particular toilet. The Korky flapper is made in the USA and comes with a 10-year warranty.

              By far the best Korky flapper I have purchased. Its lifetime is about 2 years—not 10. All Korky flappers eventually leak. This one lasted 2 years or so but the difference is that it did not deteriorate as much as the previous ones
