# Many People Still Think That These 2 Buttons Are Just for Flushing: Unlocking the Secrets of the Toilet’s Dual-Flush System
## What Is a Dual-Flush System?
A **dual-flush toilet** is designed with two flush buttons to offer different amounts of water depending on the type of waste being flushed. The smaller button typically uses less water, while the larger button uses more. The goal of this system is to give users the option to use less water when possible, saving both money and the environment without compromising on cleanliness and hygiene.
Most modern dual-flush toilets are equipped with a two-button mechanism:
1. **The Smaller Button**: This button typically releases about 1.1 to 1.6 gallons (4.2 to 6 liters) of water. It’s designed for **liquid waste**, such as urine. This smaller flush uses less water and is sufficient for liquid waste, which doesn’t require a large amount of water to clean.
The dual-flush system is part of an effort to conserve water in households. Toilets are responsible for a large portion of indoor water use, and by using less water for liquid waste, you’re helping to reduce water consumption significantly.
1. **Water Conservation**
In areas where water is a limited resource or where water prices are high, the dual-flush system offers a significant advantage. By using less water for liquid waste, households can save hundreds of gallons of water every year. This is especially important in regions experiencing droughts or water shortages.
