Perfect Replacement Part
By Large Richard
On virtually every toilet the model number is cast into the inside back of the tank. My American Standard toilet has a model 4072 tank which calls for a 738159-0070A Flapper. My specific flapper and the flapper for several other American Standard toilets has been superceded by this part. The flapper is identical to the original flapper I removed from my 16 year old toilet except that the rubber is soft and pliable. My old flapper had become hard and was letting water leak from the tank into the bowl causing my fill valve to cycle from time to time.
Be careful removing your old flapper. If you bust one of the trunnions that the flapper hinges on you will have to replace the overflow pipe and that requires removing the tank.
What is notable is that the directions on the packaging include a Bead Setting Chart. The bead settings for the various original flapper part numbers vary from 1 to 18, that is the number of beads that are supposed to be between the top of the flapper and the bottom of the float. The float is held in position with clips that snap onto the ball-chain above and below the float. My model calls for 11 beads and that is how I set the float initially. The float position determines the timing of the flush. My toilet is supposed to be a 1.6 gallon model and I presume the bead setting corresponds to that specification. At 11 beads my flapper was closing while the tank was still about half full so I chose to move the float to 7 beads. Set at 7 beads my toilet isn't even close to completely draining the tank but it is a more complete flush than at the 11 bead setting. I suggest you use the bead chart as a starting point and then decide from there how you want to balance water usage with having an adequate flush.
This is a top quality part, much better than a universal replacement. The one I received was made in Taiwan. I have come to have great respect for Taiwanese manufacturing. I hope this flapper lasts for 16 years like my old one did.

Worked like a charm on my 25 year old American Standard
My toilet was running and I tried a "universal" flapper from my local hardware store. That just made the problem worse! The "universal" flapper didn't seem to close properly.
This model is nicely weighted so it closes with a solid "thunk" every time.
The only problem I had with installation is that my toilet is so old that the model number was not listed on the package. So I initially had no idea how to set the float. I had to experiment awhile to get it right.
***HINT*** setting the float lower (closer to the flapper) makes the flapper stay open longer. So if your flapper closes too early, giving too short a flush (not enough water from the tank goes into the bowl), set the float LOWER. If you want a shorter (less water) flush, set the float HIGHER.

It is worth the expense of getting a true American Standard flapper...
By R. Fleck
I had a toilet that had been problematic over the years and we replaced most of the parts with off the shelf stuff available at typical big box stores. I finally took the time to research the exact flapper specification for my American Standard 4112 tank. It installed fairly easily after wrestling the old flapper off which had become quite rigid. I used the recommend bead setting for the yellow float for my specific tank and it didn't work correctly. I simply experimented and moved the yellow float closer to the flapper (maybe only 2 or 3 beads) and it works great. Wish I had done this years ago and avoided the frustration of having to hold the toilet handle down for several seconds to ensure a good flush.
