Rated 5 out of 5 by from Only for 1993 or older toilets For those people having problems with this flapper, be aware that models 500, 501, & 503 are only for use with old toilets manufactured in 1993 or earlier (3.5, 5.0, or 8.0 GPF). If you use this flapper in a 1994 or newer toilet, you will experience problems. It is not designed for the water-saving, low-flush toilets. For 1994 or newer toilets (1.6 GPF or less), you must use model numbers 502, 5051, or 5403. See the Fluidmaster website for more information.

Rated 2 out of 5 by from Flapper Sticks Also I had the same experience as kenfixerupper. The flapper seals nicely and fixes the slow leak, but it consistently sticks in the up position. If you don't "jiggle the handle" and make sure it closes, you waste a lot of water if you don't catch it right away. The design seems to have not taken into consideration the diameter of the standpipe. To solve the problem of sticking, I had to file down the arms creating more space between them so they don't stick to the standpipe. It works well now, but it took a lot of fussing with a file grinding it down until it stopped sticking. Definitely not a quick or simple fix for the beginner.

Rated 5 out of 5 by from great performance for American Standard toilet built in the 1960's I have worked with mechanical things most of my life. In my work, I have come across many different flapper designs. For an American Standard toilet made in the 1960's, this flapper cannot be beat. The toilet probably has a better flush with this flapper than it did when it was new. The location where the chain anchors to the flapper is perfect for this old toilet. The fancy clip that attaches to the toilet tank lever appears to be a very well thought out design. Even if I had to replace this flapper every year, I would not mind because this flapper makes this particular toilet work very well. It appears that we are probably using less water now with this flapper, but I don't own the equipment needed to prove this. Try this flapper on your old toilet. It might not be so sturdy, but it works very well.

Rated 5 out of 5 by from Works Great I tried using another type of flapper and it was so hard to flush the toilet. This was so easy to install and work real good. Does not leak and easy to flush toilet.

Rated 2 out of 5 by from good seal, Sticks UP I have replaced plenty of flappers. Never had a problem with Fluidmaster or these Dura Flush flapper valves until recently. The flapper stayed in the UP position. I had to keep adjusting the chain length to get it to flush normally. Occasionally it does hang up. However the seal is very good. I just have to keep an eye on it especially if we are on our way out for an extended period of time.

Rated 1 out of 5 by from Flapper Sticks Bought this flapper Nov 21. Installed it. Works.... OK fine. Another toilet began leaking around the flapper so went back to my favorite local Home Depot (I really do like the store and the people !) and thought, why not, pick the one that worked last time -- for an identical toilet tank. Nooooo... though this one definitely cured the slow leak around the edges (both tanks only 3 years old -- the seat was clean and smooth, no burrs). However... the one I bought three weeks ago sticks around the standpipe, it does not fall back down... it holds on. Water runs full force for hours if we don't hear it. Put washers on the standpipe "ears" to widen the stance... it still sticks. The normal water use of 3000 gal per month has climbed up to 9000 gal per month. Costing me $$$.
