Nowadays, toilets are not the same as those that our grandmothers used for many years. Modern technology has brought about another new toilet design.

The toilet equipped with two buttons on top of each other. But do you face issues while flushing it? If yes! Then here is how you can do it.

To flush your toilet with two buttons on top, push the button on top of the tank, then hold the button on the bottom of the tank. This is a handy shortcut to keep in mind if you are cleaning the toilet and need it to flush immediately.

What Is Dual Flush Toilet?

How To Flush Toilet With Two Buttons On Top

A dual flush toilet is a type of toilet that uses two buttons to flush. One button flushes only the liquid waste, and another flushes the solid waste. The liquid waste button is usually labeled as “1”, and the solid waste button is usually labeled as “2”.

When I first used dual flush toilets, I was pretty surprised and impressed that you can choose between two flushes in a dual flush toilet.

The first is a full flush, which uses just a small amount of water to move all of your waste out of the bowl. This type of flush is best for solid waste, such as poop. 

The second type of flush uses more water, but it’s still less than what you would use in a traditional toilet. This kind of flush is used for liquid waste, like urine.

This system has been around Europe for several years, but it’s just recently made its way over to the United States.

How does Dual Flush Toilet Work?

The dual flush toilet uses two different-sized holes to allow water to be used in a large or small quantity. The giant hole is used when you flush the toilet, while the smaller one is used when you need to clean the bowl quickly.

Toilet Flush

Water flows through the large hole and into the bowl when you push down the lever on a dual flush toilet. This action causes waste material to move through pipes and out of your home.

The water needed for this process varies depending on how much waste material is in your toilet tank.

Cleaning Flush

When you push down on the lever again, water flows through a smaller hole into your toilet tank.

This action flushes out any remaining waste material from inside your toilet bowl.

So it can be washed away easily during cleaning later in your day.

How To Flush Toilet With Two Buttons On Top

You’re in the bathroom and just realized that you need to flush the toilet. But wait—there are two buttons on top of it! What do you do now?

Don’t worry; I’ve got you covered. I’ve compiled a step-by-step guide on how to flush the toilet with two buttons.

Here’s how:

STEP 1: Look at the top of your toilet’s tank and identify which button is larger than the other. That’s going to be your flapper valve button, which is the one that will open up a hole when pressed. The smaller one will be your fill valve button; pressing it will send water into your tank.

STEP 2: Press both buttons at once. If this doesn’t work for whatever reason (you may not have enough pressure), try pressing them separately instead of simultaneously. If neither works, there might be something wrong with your toilet or piping—you should probably get someone who knows what they’re doing to have a look before continuing with this tutorial!

STEP 3: Once both buttons have been pressed simultaneously or separately (depending on what worked), wait 60 seconds before trying again.

Benefits Of Using Dual Flush Toilet

Okay, so till yet, I have guided you about the dual flush toilet and how to flush it. But as we all have a traditional toilet installed in our homes, I am pretty sure many of you have a question rising in your brain, why should I switch my traditional toilet to a dual flush toilet?

Am I got you? Well, if yes, then I will discuss some of the benefits of having a dual flush toilet in your home. So let’s have a look.

Saves Water

Water conservation is essential today, and that’s why the dual flush toilet was invented. It saves not only water but also money and energy.

It uses less water for your number one or big flush and, in return, more water for your number two or small flush.

This means you do not need to use as much water every time you flush your toilet, which also helps save on bills.

The dual flush system saves you money by using less water while flushing both liquids and solids by saving up to 20 gallons per person per day compared with single-flush models like older toilets, even more, if installed with rainwater catchment systems.

Not only are they better for the environment by conserving natural resources, but their superior design has also made them popular among homeowners who want their homes built green.

Supports Both Low Flush and High Flush

As I have mentioned above, the high flush is for solid waste, while the low flush is for liquid waste.

Dual flush toilets use less water than single flush toilets, making them more environmentally friendly than single-flush models. 

Users can adjust the dual flushing mechanism to suit their needs, which is why it’s such a popular option in homes with different preferences on how much water should be used during each type of bathroom use in their homes.

Improves Drain Line Flow

Dual flush toilets are more cost-effective; dual flush toilets also use less energy because they don’t have to heat as much water. This means less strain on our already overtaxed electrical supply system.

As if all this weren’t enough, dual flush toilets can be used by those who need assistance with their daily bathroom routine because they offer an easy alternative for people with limited mobility or dexterity in their hands. 

The buttons on these units make it easier for even children and seniors (who may have trouble operating regular toilets) to operate them successfully every time.

Has Handle on the Top

There are some benefits to a dual flush toilet. One of the most beneficial is that it has a top handle. The handle is flush with the top of the toilet, making it more accessible and easier to grab.

It’s also easy to pull down and push up, making flushing easy for everyone in your family, regardless of age or strength.

The easy-to-grab handle makes using this type of toilet extremely convenient because you won’t have to bend over as far as you would if there wasn’t one!

This is especially helpful when using public restrooms with no toilets near any sinks–make sure there aren’t any mirrors nearby!

Improves the Aesthetics of your Bathroom

Another advantage is that it will improve the aesthetics of your bathroom. The dual flush toilet has a sleek and compact design, making it look good in any bathroom.

It is also straightforward to install, so you can even do it yourself without hiring a professional.

Dual Flush Toilet Problems

Beyond its benefits, just like every modern device, dual flush toilets also have some drawbacks.

And I should say that knowing the drawbacks of a device you want to install in your home must also be good. So here, please take a look at some of its drawbacks.

Need Constant Cleaning

A dual flush toilet is a great way to save water. But if you have one, you know that keeping clean can be a pain.

The issue is that the water tank and bowl are both exposed to the air, which makes it easy for germs to grow.

If you don’t clean the tank (which you should do at least once a month), it will become clogged with bacteria, which can cause unpleasant smells and even illness.

Increased Clog Risk

I believe that the dual flush toilet is an excellent idea in theory, but it’s increased the risk of clogs in the bathroom.

The dual flush toilet uses water pressure to clean up the waste, and it does this by flushing two different amounts of water at once.

This means you must be careful about how much liquid you put into your toilet bowl because too much can cause a clog.

If you live in an area with a lot of rain, this might not be such a big deal for you, but if you live somewhere that doesn’t see much rain throughout the year, this can be problematic.

Expensive To Repair

One more problem with Dual flush toilets is they are expensive to repair. This is because they have more parts than a single flush toilet.

They also use more water and electricity than a standard toilet, which adds up over time.

In addition, dual flush toilets are more complicated than other types of toilets. If you need to fix one, there may be more parts involved than you expected or parts that are harder to find.

This can lead to extra costs for repairs or replacements when something goes wrong with your dual flush toilet.


In the end, I hope this guide about how to flush toilet with two buttons on top helps you deal with dual flush toilets next time.
