We purchased a generic flapper from a local hardware store that was said to fit our American Standard toilet. Well it worked but that is all. We then purchased this American Standard 738920-0070A 3-inch Flapper Assembly. Our toilet is like it was when we 1st purchased it. The flush has more power and the flapper does not allow the toilet to leak. Of course we wish we had purchased this product first.

My Cadet 3 toliet flapper started to leak after about 2 years (no chemicals in water, good clean water also).

When to HomeDept/Lowes...only could find a generic ($8-13!).
I got one...installed...leak fixed, but flush wasn't as powerful anymore.

Looked online.... found the item listed here for an AMAZING price.

Upon receipt, I was pleasntly surprised that the black-rubber gasket had been replaced with what appears to be a semi-clear silicon gasket.
It is the exact OEM part..not a aftermarket. heck, even the chain is pre-adjusted perfectly.

For this price I'm very happy!

It does not perfectly fit for my American Standard Cadet 3 toilet. The interval of the hooks is two wide, so that I have to push in this flapper to the flush bulb. Finally it is working fine, but I will not buy the same one next time. It seems there are two versions for Cadet 3 - 1.6 GPF and 1.28 GPF. This item is for 1.6 GPF and mine may be 1.28 GPF. Be careful to choose a right one for you.

I received this white flapper directly from AS and it failed in 1 year. Leak started showing up where the fill valve would kick in to refill water every 45 minutes.

The problem lies with the ridged flapper plastic surface that is in touch with the flapper's silicone seal (see photo).

Over time, the silicone seal would become soft and because of this ridged plastic surface the silicone seal would follow the ridged shape and produce a rippled surface that's in touch with the tank's opening. This non-flat surface allows water to slowly leak out from the tank.

For months now, I've been on the hunt for the right flapper. I have a Vitra toilet. I tried Fluidmaster (recommended by Vitra as my toilet model has been discontinued therefore no more parts for the toilet), Korky, and a few others in hopes of finding just one flapper that would work for my toilet. None of them worked and I tried at least 5 and all of them were more expensive than this flapper. One Fluidmaster cost almost 3X the price of this flapper and still allowed my toilet to leak or not flush properly:-/ I ended up using the original flapper since it was better than all the other ones I bought. However, the constant running and disengaging of the flapper upon flushing the toilet led to the daily removal of the toilet tank cover and the repeated adjustment of the dysfunctional original flapper. I was about to pull my hair out always having to stick my hand in the toilet tank and adjust the flapper just so I can flush the toilet. I'm always on Amazon and not sure how I missed this flapper but decided to go one more time on the site to look for one that looked like mine. Lo and behold I found it! Although it's for American Standard toilets this flapper was the exact fit for my Vitra toilet and looked pretty much like the original flapper that came with the Vitra toilet. Now there's no more running toilet and the toilet flushes as it used to before things went south. I'm over the moon! Can't believe how happy I am about this. Because I've been so disappointed by the other dud flappers I also ordered a couple more along with this American Standard flapper. Needless to say the others have been sent back. If you're in need of a flapper and it looks similar to this don't hesitate to buy it. It just might be exactly what you need and at this price this flapper can't be beat. Thanks again Amazon!!!

Local big box stores did not carry this replacement part. Tried two other korky brand replacements that did not work before ordering this one. Wish I would have ordered this instead of driving back and forth to the store.

When my original flapper started leaking I bought an adjustable replacement flapper at our local h/ware store. Installed the aftermarket replacement & had prolems with a 'complete' flush. After trying every adjustment I could I gave up & ordered the OEM from Amazon. Not only is it cheaper but it cured my flush problems.
Soon after I had another flush problem as it was taking 2 or 3 flushes to get a 'complete' flush. After more research I found that in the bottom of the toilet at the front of the bowl, there is a hole that could be plugged. After flushing the toilet I sponged all the water out & found that the hole was in fact plugged. I cleaned out the blockage (lime or calcium build up, I guess) & now my toilet works like a 1.28gpf toilet should. A 'Complete' flush each & every time.
I recommend using only the OEM American Standard flapper assm as it is less money & works better.

The flapper which came with my toilet had a black seal with appeared to be some sort of foam with a very thin plastic like coating. The coating bubbled, which caused my toilet to leak slowly into the bowl.

This new flapper installed in under a minute and has what appears to be a silicone (or something similar) material which, at least so far, works great and seems like it should last a very long time.

The part number is exactly the same as what I removed, so it seems the manufacturer likely improved the product due to poor performance of the original part.

I couldn't find this specific part in stock at my local big-box stores, so I turned to Amazon (where the cost was the same as big-box with free Prime shipping). A perfect repair for my American Standard Cadet one-piece toilet. Gently snap off the old leaking flapper and snap on this replacement for a quick repair! Note: the 3" neoprene seal only is available online from Home Depot for about $2.00 (3 in. Toilet Tank Flapper Replacement Silicone Seal, SKU# 1000707192, Internet/Catalog# 204374256).

I was impressed with this. Both of my five year old toilets were ghost flushing. I realized that the black rubber gasket around the bottom of the flapper was the culprit - the rubber developed small bubbles in the surface that allowed a tiny bit of water to leak. Over time, the water level would drop enough to cause it to fill.

These have a silicone gasket and I imagine that they won't have the same issue as the rubber ones.

It was an easy 5 minute repair to replace them.
