        1 Answer
        Answer This Question

        A:  Based on the limited information we are unable to confirm. Kohler is a brand and within that brand they use different styles of components. We would need more information about your specific model toilet.

          NOT Universal!!
          This is supposed to be a UNIVERSAL fill valve AND flapper. It isn't! The fill valve fit my toilet and instructions are clear and fairly simple. Flapper is weirdly made and does not fit my toilet at all. The clips were set too wide to fit and the ball part of the flapper was set too far out so the ball rests on the edge of the drain hole. Also, once installed, the fill valve dribbled water from the top portion into the tank. I pressed firmly on the cap at the top and it stopped. Can I trust it?

          The reason why it won't fit your toilet is because you probably have a 2 inch flush valve and not a 3 therefore the arms are too wide on the 3 inch flapper. You would need a smaller flapper where the arms are closer. If the cap leaks when the tank is refilling and stops when the tank is filled then that's normal as it's a pressure release for the fill valve. If it leaks after the tank is full then the seal in the cap is not sitting properly. For this we recommend to purge out the fill valve as instructed in our installation guide troubleshoot section as there may be grit or debris that may have gotten into the fill valve when the water was turned back on.

            The fluid master PerforMAX "universal" flapper did not fit my toilet.. I had to go to my local hardware store to by a standard flapper. I will not purchase fluidmaster products in the future.

            When it comes to flappers there are 2 sizes. A 2 inch and 3 inch. We advise to measure the diameter of the current flapper or the of the hole it covers to identify the size that is needed as every company uses either or.

            Don't waste your time with this product.
            Ordered three, all arrived in great shape, were delivered quickly. My husband completed the first one and it was so easy. The second leaked from under the blue cap. We read instructions, looked online, and watched the video. Flushed it even though we have filters. Nothing seemed to work, so we thought it was a fluke and took the other one and put in the second toilet. All appeared well. Took the third one back and received a refund. Came home and checked both of the toilets and they were both leaking. My husband called and was told to remove the seal and run it under hot water, dry and then grease it with olive oil. We did this and it appears that it fixed the problem, but it is a heck of a thing to spend so much time to fix something that is new. We have always used Fluidmaster and were very disappointed. I believe there is a flaw with the seal under the blue cap.

              Fill valve worked just fine as expected however the flapper valve was missing hook on one side so wouldn't stay attached to fill tube.

              Best Instructions and online service ever!
              I am an office worker and not much of a Do it Yourselfer, but the instruction manual and online instructions made the job easy. These days you are lucky to get an instruction manual at all, but there's was wonderful, step by step instructions with photographs at each step. The online website and videos were top notch as well. If all that is not enough, they have both online help, messaging, email, and yes even a PHONE NUMBER! The product works perfectly! I highly recomment this product and even more this manufacturer, I will definitely use their products again any time I have need.
