A traditional single-flush toilet uses 6+ liters per flush, no matter what.
With a dual-flush system, households can save up to 20,000 liters (5,300 gallons) per year — enough to fill a backyard pool!
💰 2. Lower Water Bills
Less water = lower utility costs.

Over time, this adds up to hundreds of dollars saved — especially in large families or multi-bathroom homes.
🌍 3. Eco-Friendly Impact
Freshwater is a limited resource — only 3% of Earth’s water is drinkable.
Agriculture and industry use most of it. Every drop we save at home helps protect rivers, lakes, and aquifers.

📜 A Brief History: Who Invented This Smart Toilet?
Plumbing Fixtures & Equipment
While the concept was explored earlier, the modern dual-flush toilet was popularized by Austrian-born designer and sustainability advocate Victor Papanek in the 1970s.
But it was Australia that brought it into the mainstream. Facing severe droughts, the country adopted dual-flush systems nationwide starting in 1980. Today, they’re standard in Australian homes — and increasingly common around the globe.
Now, countries like the UK, Canada, Germany, and parts of the U.S. are following suit, incentivizing water-efficient fixtures to combat growing water scarcity.

✅ Best practice:
Small button = liquid only
Large button = solids
If the small flush doesn’t clear the bowl? Then use the big one.
