You’ve seen them.

You’ve used them. But have you ever stopped to wonder what those two buttons on your toilet actually do?

Spoiler: They’re not just for style. And they’re definitely not “both flush the same way.”

If you're using only the big button — or hitting both at once — you might be wasting thousands of gallons of water a year without realizing it.

Let’s uncover the real purpose of dual-flush toilets — so you can save water, lower your bills, and make every flush count.

Because real sustainability isn’t about grand gestures. It’s about smart choices hiding in plain sight — like two little buttons on your bathroom fixture.

🔍 How Dual Flush Toilets Actually Work

Dual-flush toilets were designed with one goal in mind: 👉 Use less water when you don’t need a full flush.

Each button releases a different amount of water — tailored to the type of waste:


✅Large Button (Full Flush)	~6–9 liters (1.6–2.4 gallons)	Solid waste — ensures complete removal
✅Small Button (Half Flush)	~3–4.5 liters (0.8–1.2 gallons)	Liquid waste — uses half the water
