Myth: Both buttons do exactly the same thing.

Fact: Each button activates a different amount of water.

Myth: You should always press both buttons.

Fact: Most toilets are designed to use one button at a time. Pressing both usually doesn’t improve flushing performance.

Myth: The small button won’t flush properly.

Fact: For liquid waste, the smaller flush is generally designed to provide enough water for effective flushing while using less water.

Tips for Getting the Best Performance

• Use the small button for liquid waste.
• Use the large button for solid waste.
• Avoid flushing wipes, paper towels, or other non-flushable items.
• Clean the flush mechanism periodically to keep it working smoothly.
• If the toilet continues running after flushing, inspect the flapper or flush valve, as it may need adjustment or replacement.

Why Water Conservation Matters

Fresh water is a valuable resource. Small changes—like choosing the appropriate flush option—can make a meaningful difference over time.

Combined with other water-saving habits, such as fixing leaks promptly and installing efficient fixtures, a dual-flush toilet can help reduce both water consumption and utility costs.

The Bottom Line

The two buttons on a dual-flush toilet aren’t just different ways to flush—they’re designed to give you a choice between a partial flush and a full flush. By using the smaller button for liquid waste and the larger button for solid waste, you can help conserve water, lower your water bill, and reduce your household’s environmental impact without sacrificing performance.
