What are the two toilet buttons for?

The two toilet buttons are for dual flush systems, designed to save water by giving you two flushing options:

Small button (usually the smaller or split side):
This is for a half flush, typically using around 3 liters (0.8 gallons) of water. It's intended for flushing liquid waste (urine).

Large button (usually the bigger or full side):
This is for a full flush, typically using around 6 liters (1.6 gallons) of water. It's meant for solid waste (feces).

Why this matters:
Dual flush toilets help reduce water consumption, lowering both your water bill and your environmental impact. They’re especially common in modern or eco-friendly bathrooms.
