6. Fluidmaster 502P21 2-Inch Universal
After reviewing the 3-inch flapper by Fluidmaster, which is going to seal a 3.5-inch drain hole perfectly, we have this 2-inch flapper by the same brand. This one is going to cover a 2.5-inch drain hole with perfection.
It should be by now pretty evident that sealing is everything when it comes to smooth flushing. So, perfect sealing is crucial, and this toilet flapper excels in that department. It is long-lasting too, so there is no need for you to replace the flapper frequently.
These toilet flappers have Microban protection on them, and that’s patented protection. No other flapper has it, except the flappers made by Fluidmaster. Though the flapper continually stays in the water, the shield helps to inhibit any growth of bacteria and harmful microbes. Thus, there will be no bad odor or breakdown of the flapper.
Though made of rubber, it has a rigid frame. So, it aligns well with the drain hole. It is universal and easy-to-install. Not just that, but it saves water too. For that, you only need to turn the flapper. You are going to notice the marks from a range of a minimum of one to a maximum of nine. Keep the flapper at 7-9 range, and you can flush the maximum quantity of water with one flush.
And if you are keeping it in the range of 1-3, then the water usage will be lower. You will have to pull the lever quite a few times as the flapper will seal the drain hole frequently when you adjust it in the lower range. So, you are saving water and not emptying the tank at one go. However, the best is to keep it in the range of 4-6. It’s not too low nor too high. A couple of pulls on the lever must be fine at this range.
Features at a glance

There might be some exceptions where it doesn’t fit as perfectly, but even with those, you can still manage. However, to get the best performance by the flapper, make sure to use it with the toilets they asked you to.
This flapper is specially made for flushes that release 1.28 gallons of water per flush. Made of high-quality materials, this flapper is not going to break down soon. The flapper chain is made of ultra-durable brushed nickel. With it, you can be sure of a superior performance that too for a long time.
Installing the flapper to the flush valve is as easy as it can get. It has a soft frame, thus bending it slightly to fix both sides to the overflow tube’s pegs becomes easy. However, it is equally sturdy, so when it seals the drain hole, it stays there pretty tight.

8. Kohler K-GP1039444 Toilet Flapper, 3-1/4 In, Red
This one is for one-piece toilets. To be precise, it is made for a few Kohler models such as Cimarron 3489, 3802, 11889, and Memoirs 3451, 3453. As you can already gauge, this is a comparatively large flapper, measuring 3 1/4 inches.
Small flappers cannot seal the larger flush valves in one-piece toilets well. So, you have to deal with constant water leakage. A good-sized drain hole requires a flapper that seals it perfectly, without keeping any aperture. And this 3 1/4 inches flapper does exactly that.
It is corrosion-resistant, so you know it is going to last. Though replacing a flapper is not something that is too complicated, nor is it too pricey as a product, if it needs replacement within months, it’s annoying. So, a flapper has to last. The more it lasts, the better.
Installing this rubbery yet solid frame into the flush valve is as easy as it can get. It takes a maximum of five minutes to set. It seals the valve from all sides and makes sure to stop water leakage.
The proper usage of 1.6 GPF of various one-piece toilets can only happen when you use the correct-sized flapper. So, when there are specific-sized flappers easily available for specific toilet models, then try to know which flapper is going to fit your flush valve perfectly.
And make sure to buy the specific size. Those who are struggling with the flush of any of the mentioned models above must try this flapper. It will seal and save water without any glitches.

9. Kohler (BLUE PART GP85160 FLAPPER WITH FLOAT)
We are reviewing each and every type of toilet flapper here. So, how can we miss a flapper with the float? This one is a Kohler toilet flapper that comes with the float. For those of you who don’t have any idea of what a float is and how it works, let us make things clear for you.
Floats on toilet flappers basically control the flappers. It is fixed in the chain and can be adjusted up and down. Depending on that adjustment, the flapper floats in the water. The lower the float is, the longer the flapper floats. So, the water flushes longer.
When you set the float higher, that means the flapper will seal the flush valve shortly. That ensures less use of water. So, set the float at a distance so that you are not flushing too much water or too little. For that, you will have to try different positions while installing the flapper into the flush.
Kohler toilet flapper uses high-quality Styrofoam floats. Just like the flapper, even the float stays in the water all the time. So, it being high-quality is essential. And Kohler makes it sure to use the best material to make the flapper as well as the float and the chain.
This flapper perfectly fits in any 1.6 GPF two-piece toilet. It is a 2-inch flapper, so it will be apt for various 2.5 inches of flush valves. The brand can be any Kohler, Kallista, and beyond.

10. Hibbent 2 pcs Toilet Flapper Replacement
Let’s talk about a flapper package. In this package, you get two pieces of toilet flapper. So, when one is worn off, you do not need to run to the market to buy another flapper. You can immediately replace it with the second piece.
If you have a Lowes toilet or an AquaSource toilet at your house, then this flapper is the perfect match. Though it is best compatible with a few specific toilets, that doesn’t mean it is not going to fit the others. It is large and apt for a 3.5 inches drain hole or flush valve. So, even if you do not have those toilets, it is going to work and seal just fine.
This high-quality silicone flapper is going to perform better than other flapper designs. It seals the drain hole tight. Yet, with a slight pull on the lever, it is going to break the seal. Hence, flush the toilet with ease.
Not just that, the rubber material is also corrosion-resistant. Add to that the stainless steel chain that is fixed to the lever. So, do not doubt it, when it claims to last 10x longer than standard flapper designs.

Buying Guide for Best Toilet Flapper
Toilet flappers not only make it possible for your toilet to flush but also help ensure extra water is not wasted from leaking or falling excessively into the toilet bowl from the toilet tank. As such, it’s important for you to keep in mind a few pointers when you set out to buy a toilet flapper.
There may be times you need toilet flapper replacements, in such cases, it’s best to read up on different toilet flappers before finalizing what to replace your flapper with.
The thing with toilet flappers is that they are designed to create a proper seal in the water holding tank of your toilet so that before or after you flush, there is tight control on the water that flushes into the bowl. This makes it a key component of your toilet.
It also helps you save on your bills by lowering your water bill. It’s probably a good idea to give the flapper some thought when replacements are needed.
Here are a few points to help you choose a flapper that’s best for your toilet and one that will last you. After all, no one wants to head to Home Depot every other week to get themselves a new toilet flapper.
Size of your flush valve
You need to understand which size flapper seal you need to get. In order to understand this, an easy reference to understand whether you need a 2” seal flapper or a 3” flapper is to look at the size of your flush valve drain opening which is located at the bottom of the tank.
If it appears to be around the size of an orange or baseball, you probably need a 2-inch seal. However, if it looks more like the size of a softball or grapefruit, you need to get a big 3-inch seal.
Look into the material of the flapper, it could be rubber or plastic. Rubber has a more flexible frame and will fit most valve drains as rubber is flexible and stretches. Plastic offers a more solid fix and forces the flapper ball to center onto the drain and seal quickly.
Plastic is intended to stop leakages for a long period of time. However, plastic does not always work with all flush valve drains.
Toilet flapper types can be adjustable or nonadjustable. Different toilets, depending on when they were manufactured, can flush different amounts of water per flush (in gallons).
Adjustable flappers are designed to flush toilets that flush anywhere from 1.28 to 1.6 gallons per flush toilets. Whereas non-adjustable flappers are designed to flush toilets that flush 3.5, 5 or more gallons per flush. Non-Adjustable Flappers come in only the 2-inch category.
Age of your toilet
Believe it or not, it helps to know how old your toilet is. There are different functions for toilets based on what year they were manufactured.
If you are unsure of how old your toilet is, ask a specialist to come to have a look or try to research further on this area. It can save you time and energy if you know which flappers go best with your toilet based on its age.
Rate of use
If your household has more people in it, obviously the toilet use rate would be more than if your household consists of only one or two members. The number of family members you have staying over or the number of friends and guests that come over on a regular basis also determines how much you should spend on your toilet maintenance.
For toilets that are used more rigorously than others, it’s probably wiser to get more sturdy parts. Toilets that are used by fewer people on a regular basis can probably do with less sturdy parts.
