Push to flush toilets with two buttons, one smaller and one larger, are known as dual-flush toilets. The two-button design is intended to offer users a choice between two different flushing options based on the amount of waste that needs to be cleared, which can help conserve water.
The two buttons represent two different flush volumes:
Small Button: The smaller button is usually used for liquid waste or light flushing needs. It releases a lower volume of water, typically around 0.8 to 1.1 gallons (3 to 4 liters). This is often referred to as the "half flush" or "liquid waste" flush.
Large Button: The larger button is designed for solid waste or heavier flushing requirements. It releases a higher volume of water, typically around 1.6 gallons (6 liters) or more. This is commonly known as the "full flush" or "solid waste" flush.
The dual-flush system helps promote water efficiency by allowing users to choose the appropriate flush volume depending on the waste being disposed of. This way, you use less water for lighter tasks, reducing overall water consumption and contributing to water conservation efforts. As toilets are one of the main water-consuming fixtures in a household, dual-flush toilets can make a significant difference in water usage and utility bills over time.
This water-saving feature has become increasingly popular in many regions around the world where water conservation is a priority. It aligns with efforts to promote sustainability and reduce the environmental impact of water usage.
