Q:Korky No. 2017 The ring that opens and closes the circular hole does not turn. Mine was set to close but I cannot turn it to the open hole. Is there a trick to turning that ring? And what is the purpose of this hole?
by|Nov 24, 2023
1 Answer
Answer This Question

A:  Opening the hole makes the flapper less buoyant and causes the flapper to close sooner and flush less water. Are you able to contact our Technical Support team?

    Q:What's the difference between the three Korky 2 inch flappers?
    by|May 13, 2023
    1 Answer
    Answer This Question

    A:  The Korky Plus Flapper (2001CM) is chlorine-resistant and has a universal design to fit standard 2" flush valves. Our Korky Ultra Flapper (100HD) is made from the same chlorine-resistant material and has the added benefit of allowing the user to control the amount of water used with each flush. The Korky Plus and Korky Ultra flappers are both backed by a 5-year warranty. Our newest 2" flapper, the Korky Ultra 2X flapper (2017CM), is also adjustable and is made from our newest proprietary material and is backed by a 10-year warranty.

      Q:Should I replace the fill valve when I replace the flapper? It seems to be functioning well.
      by|Mar 26, 2023
      3 Answers
      Answer This Question

      A:  If the fill valve is working I would just replace the flapper.

      by|Apr 1, 2023

        A:  Hello. Thank you for contacting Korky! There is no need to replace your fill valve after replacing your flapper. As long as it is functioning well and not leaking, leave it as is.

        by|Mar 27, 2023

          A:  I replaced fill valve also. I felt if one part failed it was not a big cost to replace it all.

            Q:6yrs and I need to replace the flapper. The water leaks into the bowl. I am so confused. Korky makes an Ultra, Premium and 2X. Will any of them fit my ToTo st706 toilet tank. I currently have a Korky flapper that does not state U, P, or the 2x.

            Answer This Question

            A:  Most ToTo toilet tanks use 3 inch flappers. The Korky 3 inch premium universal will fit the ToTo tank. The Korky 2 inch flapper is probably too small for ToTo toilet tanks. ToTo obtains Korky flappers and installs them as OEM parts on their toilets.

              A:  The Korky Ultra and 2X flappers are both compatible with the ST706 tank.

                This Korky product will degrade and break over time. This company seems incapable of creating a product that can withstand water.

                  For years I have dreaded the words "I don't like the level of the water in the toilet bowl." or " I don't like the double flush". To me these phenomena don't matter as long as.....you know ...….everything that needs to "disappear" after a flush is truly gone. But as they say,the secret to a happy life is a happy wife. So this trip to the Home Depot I decided to spend a little more money on the Korky Ultra flapper. I turned the ring to expose the hole in the flapper and then turned the knob on top to decrease the number from its maximum by two. I was rewarded with success within minutes. Just the right level of water in the bowl and no double flush. Don't throw your marriage down the toilet. Buy the Korky Ultra Toilet Flapper.

                  There are six settings so it can do anything one wants. Imagine, six settings on a toilet flapper. Problem is the directions are not clear which is small / medium / big flush, etc so I just set it in the middle. I could probably look it up on website and educate myself and pick a better setting for my needs, but the directions that come with it are not quite there yet.

                  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.

                  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.

                  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.

                  Fit just like it said it would
                  I had clean my tank with Hurriclean tank cleaner and noticed my tank flapper was beginning rubber decay. The Korky water flapper perfectly replaced my older flap without any need of cutting or adjusting. My original flapper was on a plastic carriage that seems a little more robust but the Korky presented to problem with the rubber structure. It was easy enough to replace without even reading the instructions. Just remember to turn off the water to the tank before changing the flapper.
