Q:Will this flapper work as the replacement for a Fluidmaster 555C Flush Valve?
by|Jun 17, 2021
2 Answers
Answer This Question

A:  No, The 555C is a repair kit with a putty ring and a flapper that is used when your flush valve seat is damaged and a regular flapper can't create a water tight seal. If you have the need for the 555C for this kind of issue removing that kit and replacing it with a flapper won't solve your problem. Now you can use the 501 flapper to replace the one that's on the 555C repair kit.

    Q:will this flapper stay open about 5 seconds before it closes so toilet will flush right

    Answer This Question

    A:  I had no problems with the amount of water this flapper allowed to go through. It was plenty enough to flush all of the waste and powerful enough to get the little bits off the inner wall too. So yes I would have to say this flapper is exactly what u are looking for .

    by|Mar 16, 2020

      A:  Yes, this flapper results in correct flush by staying open appropriately. I installed in a circa 1986 toilet on 3/22/2018 and today is 3/16/2020 and the flapper has performed fine without problems.

        A:  The time varies with the capacity of your tank. The flapper stays open as long as the water level stays high enough for it to float.

        by|Mar 18, 2021

          A:  How long the flapper stays open is dependent on a number of things, and we would have to ask you a few questions about your toilet to determine which flapper you would need, and about how long it should be open for.

            Answer This Question

            A:  I'm sorry, but I don't know the answer, as the toilets I used these flappers on had other fluidmaster parts on the inside. But, I have to say, the fluidmaster flapper is excellent and easy to install if used on the right toilet.

            by|Feb 8, 2020

              A:  It fit my Kohler toilet yes

                    I had been searching for a flapper that works on my older downstairs toilet (pre-1990) and found it with this one. After installation, I turned off the water supply for 24 hours and the level in the tank remained constant.

                    I'm glad that I found this toilet clapper. I'm glad that I ordered it online, instead of having to find it myself in the store. It was easy to install, and it worked great.

                      Nicely made but online description needs to highlight for older <1993 toilets so didn’t use.
