Top 7 Best Toilet Flappers

Best Toilet Flappers

Buying the right toilet flapper is essential as it controls and regulates the water inside the bowl. If your toilet makes continuously hissing noises, or you see water leaking after every flush, then that might be because your toilet flapper system has failed to do its job.

In such a scenario, replacing your toilet flapper system is the best choice. But the biggest issue is which one you should buy. Not all toilet flappers are made equally, and it gets very confusing to pick one out of them as a wrong decision would lead you to waste your money.

How to pick the right toilet flapper?

While buying a toilet flapper is not rocket science, there are a few things that you should take into consideration to ensure you are making the right decision –

Material

Looking for material can be tricky. That is because most commonly, toilet flappers are made of a combination of rubber and plastic. The rubber provides a tight seal to prevent water leakages, while the plastic offers rigidity and connects the flapper to the overflow tube.

While the material on all of the flappers looks similar, each of them is built differently. Therefore, you should look closely at the quality of the material or take an expert’s opinion into consideration. Overall, a good-quality flapper would last between three to five years.

Type

When buying a toilet flapper, you might encounter different types of products. Generally, we can classify flappers into three separate categories that include –

Rubber Flapper

Rubber flappers are the most common type of flappers you would see nowadays. It looks like an upside-down hat that gets attached to the opening of the valve. The best thing about rubber flappers is that they come in different sizes, making them easily suitable for all types of toilets.

Seat Disk Flapper

Seat disk flappers are one of the oldest types of flappers. These flappers are mainly made of sturdy rubber and look like a rounded disk that fits the valve. Whenever you flush, this flapper lifts up and then drops it back to fill the tank again.

Though it is easy to replace and relatively cheap, these types of flappers are a bit bulkier in size. That makes it take a lot of space in your toilet water tank.

Tank Ball Flapper

Tank ball flappers are the rarest type of flappers, designed to fit some specific toilets. These flappers contain a rubber ball that sits on the drain hole to hold water inside the water tank. When you flush, the system plugs the flapper out, allowing water to drain from the tank.

Size

The next thing that you should look after is the size of the valve. Modern toilets usually feature 3 to 4 inches wide valves, while most older models have 2 inches wide valves. If the flapper is too small or too large, it won’t work efficiently, and the water will leak. So, measure the size of the valve to ensure you are buying the right flapper.

GPF Compatibility

Another thing that you need to take into consideration is how much water your toilet uses in each flush. Most commonly, home toilets use around 1.3 to 1.6 gallons of water in each flush, but these numbers can vary. If your toilet uses water between these ranges, you will need a 3-inch flapper for that.

Some other toilets even use lower and higher gallons of water per flush and come with different dimensions, requiring either a small 2-inch flapper or a big 4-inch flapper.

Closing Time

Lastly, you should be looking at the closing time to ensure you won’t waste an excessive amount of water while flushing. However, if the flapper closes before emptying the water tank, it will not clean your toilet efficiently, and most commonly, you will need to flush again.

The good thing is, most flappers come with adjustable dials that allow you to adjust how long you want valves to be open for each flush.
