Title: The ONLY Flapper you will ever need
Review: With rental properties, huge remodels and a number of personal homes, I have had to replace dozens of flappers. Unfortunately it took me a bit to find the Fluidmaster 555. But now I am convinced this is the best flapper for all kinds of toilets. I have used it in one piece, two piece, old and new toilets. I recently had a Kohler one-piece 70's style toilet (Rialto, I think) that specifically said this kind of flapper would NOT work. I special ordered the Kohler part and it was WORSE. I finally went out to the store and bought the Fluidmaster 555c. Despite the tight space, it worked great. Installs in minutes and ALWAYS works.
