American Standard738920-0070A 3-Inch Flapper Assembly, White

I had "ghost flushing" on an American Standard 4021 toilet (the toilet was built around 2003). The original flapper was black (and this one is white) so I was a little concerned about the fit. But it worked great, fits well and the leak is gone. And it seems to flush well.

Very well made, direct replacement and great price

IT WAS JUST LIKE THE ORIGINAL

Perfect

My original only lasted about 1.5 years.But I do use a (chemical) bleach tablet from Clorox, which warped the original black rubber gasket ever so slightly, just enough to give me a slow leak.I agree with the other reviewer; kind of. About the Box store wants to sell you some Generic for about $10 more than this deal. [I got mine here for $5.15 w/s&h 9/2011]But, if you have some customizing abilities about you. You can replace just the gasket of the flapperjust by buying a flat sheet of 6"x6" 1/8" thick. "Plumb Pak Rubber Washer" Item #: 31448 Model #: PP25547 right at lowes for $1.38. (it's red clay color) Which is what I did before I ordered these much more easy, streamlined, replacements. [Even Amazon sells them, but for more $. Rubber Packing Sheets, 6" x 6" Red But it doesn't state if it's 1/8" thick. you do not want 1/16" thick]These make your own gaskets, aren't anywhere near as cheaply made as the originals, or the replacements.Which is the first thing I noticed.[How to]That gasket slides out from under that center plastic piece, the original gasket looks just like a flat donut.Then you just use that as a pattern to draw out on the new gasket sheet. I simply used a pair of scissors and carefully cut out the new gasket. (just like it was arts & crafts).Slide it over, and back under the plastic center, which requires a bit of effort sliding it back and forth till you get it under.. But the trick is to get one side at a time slide under. Not a women's job for sure. (I don't mean that offensively) Just as you did when you pulled it out from under in the beginning. Only in reverse. Don't even think of using a screwdriver, you might crack the plastic, and it's really not needed. Remember, it's a tight fit so you don't have a leak.I still have the heavy duty custom made gasket installed. [8 months now]I'm betting it will last about 3-4 years. [even with chemicals] (I'll update this later in time if I'm wrong)I didn't do all this to just save $3. I'm looking at the longevity of not performing any part of this task. Either with this replacement sold here or the custom gasket.But hay, I ordered this because if I get in a jam with a leak, I'm not pressed for immediate attention and water is not being wasted. I can just use this new replacement till I grab a new heavy duty gasket sheet from lowes.Made in America,. Built in America,.. You know it's gonna last longer.

The arms are too wide to connect to the valve. I fist had to Find a 3” American Standard flapper because the “universal” flappers you can pick up conveniently at any hardware store are too small for the AS assembly. I was so relieved when I saw the 3” AS flapper and ordered it and it fit the hole… but then, after managing to get the old flapper off, I found out that the original AS flapper has arms that are 2 1/2 “ wide, while the new one’s arms are 2 3/4”. I am at a loss here as it is literally the correct part #. It appears there is no way to get an AS flapper to fit my AS assembly 😭I made a work-around by removing and swapping the rubber rings. The new ring in no quite as wide as the original but it is functional for now. I guess I have to replace the entire valve assembly and flapper in order to fix it properly due to AS changing their design. I can tell you I won’t buy another toilet from American Standard. I will be looking at the flapper and stem assembly to make things easier the next time I have to replace the flapper 🤦🏼‍♂️

Exact OEM replacement. Installs and drops right in. You can fix a toilet in less than 10 minutes.You won't go wrong with this part.

I mistakenly bought this flapper to fix a leaking American Standard Cadet 3 with a 3-inch flush valve. You'd think that since American Standard sells both toilets and toilet parts, that an American Standard toilet would use American Standard replacement parts, but you'd be wrong. Apparently, my American Standard Cadet has universal Fluidmaster components inside, and the two flappers ARE NOT INTERCHANGEABLE.If you go the American Standard's website, they will tell you to pay attention to the flapper's color. If you have a white flapper then buy a replacement white flapper (this one). If you have a red flapper, then buy a red flapper (FluidMaster). There might be other combinations, but the moral of this story is to buy your specific flapper model instead of buying something for the Cadet toilet because American Standard used different, non-interchangeable components within the same model toilet during different years. For me, I needed this one.Key differences between the American Standard 738920-0070A VS the Fluid Master 5403 are that the mounting ears on the Fluid Master Flush Valve are TOO SHORT to mount the American Standard 738920-0070A. Also, the inner diameter of the silicone gasket from the 738920-0070A is significantly larger than the Fluid Master 5403.Pro Tip: You might be able to find just the flush valve seals. These new 3-inch flappers have a sturdy plastic fame that's unlikely to break or warp...the part that usually needs replacement is just the valve seal, which is basically a silicone ring.
