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

Most 3" flush valve applications are on newer toilets, including 1.28 gallon per flush High Efficient Toilets (HET's). If you have confirmed that your specific application has a standard 3" flapper/flush configuration, then the Fluidmaster Flush Valve Kit should work.

You can probably find the flapper very easily on the toilet parts display at Home Depot. It's inexpensive. Make sure you get the right size flapper! If you can't remember visually what you need, then I suggest you cut off your toilet water supply, flush and drain the remaining water, remove the old flapper and take it with you.

You can probably find the flapper very easily on the toilet parts display at Home Depot. It's inexpensive. Make sure you get the right size flapper! If you can't remember visually what you need, then I suggest you cut off your toilet water supply, flush and drain the remaining water, remove the old flapper and take it with you.
***NOTE: I have found that these flappers with the white semi-transparent/ translucent gaskets are prone to blisters! This causes your toilet water to "run" at all hours during the day and night. If randomly running water is your problem, I have a suggestion for you. Check the gasket to see if it has any rises or blisters by rubbing it with your fingers. If it does, take a sharp item (like a razor) and poke the blisters just enough to release the trapped water. After bursting any and all blisters, rub the surface to see if you missed even a tiny blister. If It's smooth all around, put it back on the flapper and return it to service. If this does not solve the problem with random running water, you may have to replace the entire flush valve with a new kit. However, checking the gasket first for blisters may save you a few bucks! Hope this helps you everyone else who has ever wondered about this!

Answer: 
Fluidmaster offers an adjustable 3” replacement flapper, model 5403, that would work for your application. However, not all stores carry this product yet. If the Fluidmaster product is not available at your local store there may be alternative brands you might be able to use.

Rated 3.6 out of 5 by 23 reviewers.
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 3.0 out of 5.0 by seal the gasket Make Sure you use some sort of sealer on bottom gasket because bacteria Will cause gunk to built up and it Will leak. I went thru 3 flappers before i decided to replace entire unit when I discovered the gunk. I believe it's due to the design of the gasket itself. I bought this as an exact replacement for original unit. October 5, 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
Rated 4.0 out of 5.0 by DYI project the installation was a bit tricky as this had to go into an older toilet. May 27, 2015
Rated 4.0 out of 5.0 by Universal 3 inch flush valve kit The kit was easy to install with very easy to understand directions. The product was engineered for easy-to-make adjustments. I listed the quality as good because, like most other plastic products, they will eventually fail and you will be replacing them again. Also, all these low gpf products don't flush that well to begin with, many times requiring two or more flushes versus one with the higher gpf products we used to have. February 10, 2015
