              Is this fluidmaster compatible with kohler tank 4520
              BySep 17, 2021
              1 Answer | 
              Answer This Question

              Based on the information provided this is a toilet manufactured before 1994 and the flapper in this kit would not work properly for this toilet. Our recommendation would be to pick up any 400 series fill valve and a 501 flapper. If you wanted to pick up a kit then we would recommend a 400CR. This would be a 400a fill valve and a 501 flapper.

                  Flapper!
                  The Flapper is not working properly. This is the worst design I have ever seen. Flapper is not closed.

                    Hat's off to the first time plumber
                    My toilet was running and I was turning it off at the shut off. That process got old really fast and I decided to try replacing the entire assembly - primarily because I didn't know exactly what to replace and I only wanted to do it one time before I would consider a call to the plumber to fix it. The package said it contained everything I needed to complete the job - no other items, accessories, tools or gadgets were needed. I followed the instructions and supplemented the instructions with a youtube video to determine the direction to screw off the fittings. Worked like a charm. That was about one month ago. No more running toilet and no leaks. This was the best investment I could have made. Thanks!

                    Worked but better instructions warranted
                    Straightforward installation but I wish the instructions were more thorough AND in larger type!

                    Works like a charm and easy to install!
                    Love this! Very basic and easy fix on a leaky toilet! The price was right and the installation was very easy. The quality of these hold up for years at a time. I had one in there before this one and it lasted over 5 years until the city shut our water off for repairs and then when they turned it back on we had a lot of dirt and debris in our pipes which clogged it up, so I would think if that didn't happen, that part would have lasted longer!

                    installation of the FluidMaster
                    toilet in main bathroom room has began to continue to run all the time, so i went to homepot and told the salesperson what was going on with toilet.salesperson promptly recommend the fluidmaster to solve the problem. got home and read the easy to install instructions. it took about 5min to take out old system and about 5min to install the new fluidmaster. the plastic parts was easy to adjust and put in place with just an adjustable wrench.
