How Does a Flapper Work?

Toilets, like many home appliance and fixtures, have several sub-components. These components help the toilet efficiently perform without flaw. It’s essential that we understand that these accessories aren’t as simple as sinks or shower areas.

Some of the essential parts of a toilet are the fill valve and the flappers. These two components are what enables the flushing mechanism of the bathroom. Thus, it’s its life support.

To better understand how a flapper works, it’s best to explain the toilet system as a whole. By defining it all together, you’ll have a more precise grasp on not just a flapper, but other parts of the toilet. That is important given that you might find yourself buying these other components in the future.

The Best Toilet Flappers For a More Efficient Toilet: Everything You Need to Know

How flushing works

Before discussing the mechanism, remember that your toilet has two significant components. That is the bowl and the tank. The tank is where the other subparts are. These parts inside the tank are the toilet fill valve, flapper, overflow tube, and fill pipe.

It’s important to understand that this is called a tank because it contains water. The water present inside the container is what helps push down and flush the toilet. Thus, it’s added water that pushes the existing water in the bowl.

So, how does the water in the tank transport to the bowl? That first starts with the flush handle that we all use. The handle is just a metal lever that’s connected to the flapper via a chain.

The flapper acts as a plug to prevent water inside the tank from leaking down the bowl. Thus, once you push the handle down, it opens up the flapper. Once the flapper opens, all that water in the tank goes down the flush valve. The flush valve then transfers it down the bowl.

After the tank empties, the flapper then closes tight until it refills. The tank fills with water through the fill valve, which gets water from the connected supplier. That then repeats until the next flush happens.

Importance of the flapper

As you might’ve noticed, the importance of this part centers around its sealing capability. Flappers are meant to be airtight plugs that prevent any water from escaping the tank when not used.

That is extremely valuable when it comes to water conservation and efficiency of the toilet overall. Let’s first discuss the latter, which is all about toilet efficiency. Flappers can make or break your bathroom when it comes to refilling time and flushing time.

Refilling always goes hand-in-hand with flushing. If your toilet does not refill correctly, then you won’t be able to flush it immediately. It can be a cause of concern, especially if you have a lot of family members using the toilet.

With that said, faulty flappers can be a culprit when your toilet is not refilling correctly. The main reason is leakage. If a flapper is a little snug on the drainage, then it will slowly suck out the water in the tank.

That is why flappers must fit perfectly inside the tank. Even just a tiny gap in between can cost your toilet its efficiency. Another thing to look at is the material of the flapper and how it interacts with the chain.

The chain connects to the flapper, most commonly through a hook. Over time, if you have a bad flapper, the material can wear down. That causes not just the flapper to break, but also the connection with the chain.

Remember, the chain is one connects the handle to the flapper. A loose chain makes your flapper just a scrap of rubber and the handle as metal junk.

The Verdict

In a nutshell, flappers may look like simple rubber plugs that are an extra need for your toilet. However, it’s importance is more than that. Hence, it can dictate how your toilet’s efficiency will be. Keep in mind; a toilet flapper is just like a gasket or a sealer of an engine. Should it be faulty, leaks are going to ruin overall performance.

When buying the best toilet flapper, it all boils down to the specifications of your toilet as well as the limitations of your budget. If you want to play it safe both for money and quality, my editor’s pick, the Fluidmaster, is the best out of all.

You can also check out the Korky 2001BP if you’re on a budget. Its quality is enough to give you quite some usage time. It is straightforward to install, comes in a universal size/design and also helps fix water leaking issues.

But then again, if you want to find the best toilet flapper that will last you years, it is still best not to compromise on price. We wish you luck in finding the best toilet flapper for your tank!
