Answer: 
Depends on the toilet. Measure the flush valve. If it's 3", you can use it. Many toilets use smaller flush valves.

The flush valve is a 3 inch Universal Flush valve that can be used on some models of American Standard toilets. To be sure that it is right for your toilet you will need to measure the flush valve outlet hole diameter. The hole size should be between 3 and 3 and 1/2 inches in diameter. Most American Standard toilets will require the standard 2 inch flush valve and some that will require even larger flush Read More

Answer: 
your toilet and tank has to be designed for a 3 inch flush valve and this valve will fit on American standard toilets but only if that was the original size of the flush valve and will not fit if the original valve was 2 inch.

Rated 3.6 out of 5 by 26 reviewers.
Rated 5.0 out of 5.0 by Universal 3 in. Flush Valve Kit For some reason American Standard has chosen to have a 3 inch Flush Valve that is extended so far into the tank that after it flushes, there is still about 4 inches of water depth left in the bottom of the tank. I replaced that flush valve with this flush valve which leaves far less water in the bottom of the tank. The only reason didn't give it 5 bars on ease of installation is the amount of time it took to get 4 inches of water out of the tank left there by the original American Standard flush valve. This wasn't this flush valves problem but still increased the time of installation by about 10 to 15 minutes. October 18, 2016
Rated 1.0 out of 5.0 by 3rd Times The Charm! Took 3 tries to get one that didn't leak right out of the box. Thanks, Home Depot! We are going to have to bring some of this manufacturing back to the USA. Bought 3 Mueller valves (now made in China)from Home Depot. 2 had pinholes in the casting and leaked $50 worth of city water before I discovered it. Just got 2 Tiger Brand Jack Posts from Home Depot online. One had no jackscrew in the box! September 13, 2016
Rated 5.0 out of 5.0 by Fluidmaster flush and overflow kit I installed this overflow kit several days ago Sep-24-16 and so far is working great and was very easy to install, I just hope it doesn't leak in the future in the overflow tube slip adjustment area. The price of only $15.00 is a very good price for all the stuff that is included in this kit. Overall this flush valve kit looks very well made and I believe Fluid Master makes the very best products. September 26, 2016
Rated 5.0 out of 5.0 by flush valve kit toilet flushes better now than the original. good flush pressure. April 5, 2016
Rated 4.0 out of 5.0 by Toilet This seems to be a good product and pretty universal January 19, 2016
Rated 3.0 out of 5.0 by Kit needs some work I have a Toto ST424S and it would periodically flush because it was slowly leaking water from the tank into the bowel. So I bought this kit to fix the problem. Pros: It's a kit that includes everything you will need; it was easy to install {after a few adjustments} and it solved my problem - water leaking into bowel causing periodic spontaneous flushing. Cons: the chain from the flapper was woefully too short so I took the chain from the old one and lengthened it. The height of the vertical tube which is the conduit for water to reach the bowel, can be adjusted to match the old ones height but it really didn't lock into place and moved several times {easily} during the installation. I fixed it by using a plastic tie around it just below the upper part of the tube {the piece that extends the length}. Instead of having nuts to secure the bolts to the bowel, they should have supplied wing-nuts. This would have helped in tight spaces since toilets are usually next to walls and difficult to get to. Lastly, the tank to toilet gasket supplied is very large. When reattaching the tank to the bowel, it makes the connection spongy and not solid. I made up for this by pushing on the tank and tightening the screws. Even then it wasn't solid so I added some material behind the tank to stabilize it against the wall. December 18, 2015
Rated 1.0 out of 5.0 by 3" valvle has slow leak, toilet is level, maybe need wieght to keep that big flapper closed tight and not leak? My only issue is with the 3" valve assembly...it slowly leaks (wasting water)....in about 8 hours it completely drains the tank... Seems these big 3" valves are harder to seal properly, my old standard 2" toilet never had this issue. Everything else about the toilet seems great....just wish they put a better sealing valve in there...now I will have to go buy a replacement flapper or valve... September 13, 2015
Rated 5.0 out of 5.0 by Easy to install. Works like a charm. OK, installation wasn't a breeze - but that is the fault of my commode - It was a pain having to take off the tank and reinstall it afterwards. (I don't know but maybe you have to do this for all commodes...) Other than that, this unit went on easily. Great , easy to follow instructions for a novice like me. September 18, 2015
