If you’re in the market for a new toilet, there are a few features you should be exploring. A common question we get is, What is a dual-flush toilet? The dual flush feature is a modern toilet design that offers two flushing options to help conserve water:
- Half flush – for liquid waste
- Full flush – for solid waste
Key Features:
- Dual buttons or a split lever: Located on the tank, allowing users to choose the flush volume
- Water-saving performance: Half flush typically uses 0.8–1.1 gallons, while full flush uses up to 1.6 gallons
- Environmental impact: Reduces water waste and lowers utility bills
How It Works:
The flush valve mechanism inside the tank is designed to release a specific amount of water depending on the selected flush. These toilets often utilize gravity or pressure-assisted technology to ensure effective performance with less water.
“Dual flush toilets are one of the simplest ways for homeowners to reduce water consumption without sacrificing performance. They offer a smart balance between efficiency and functionality.” – Jason Keller, Certified Plumbing Designer (CPD)
Because of their water-saving benefits, dual flush toilets are a popular choice for eco-conscious households and may even qualify for rebates through local conservation programs.

Pros vs. Cons
Dual flush toilets offer several advantages, most notably their ability to conserve water and lower utility bills by giving users control over how much water is used per flush. This eco-friendly design makes them ideal for sustainable living and can even qualify for rebates in some areas.
However, dual flush toilets can be more expensive upfront than standard models, and their flush mechanisms are sometimes more complex, potentially leading to higher repair costs. Additionally, users unfamiliar with the dual button system may not always use the correct flush, reducing efficiency. Despite these drawbacks, many homeowners find the long-term water savings and environmental benefits worth the investment.
Conclusion
Dual flush toilets are an excellent choice for homeowners looking to reduce water usage without compromising performance. With two flushing options and efficient design, they offer both environmental and financial benefits. While the upfront cost and maintenance may be slightly higher than traditional toilets, the long-term savings and sustainability make them a smart investment.
