What Are Dual Flush Toilets and How Do They Work?

dual flushUnlike traditional toilets, which offer a single flush mechanism, dual flush toilets allow two distinct flush options: a low-volume “half flush” for liquid waste and a high-volume full flush for solid waste.

In doing so these systems address the inefficiency of traditional flushing toilets, which use the same amount of water for both solid and liquid waste. With a dual flushing system, you can choose the appropriate flush in accordance with the waste you’re disposing of, enabling you to save water while effectively flushing the water in the bowl. So, how do these toilets work?

The low-volume flush, alternatively called a liquid waste flush, uses less water to remove liquid waste, such as urine. The high-volume flush, or ‘solid waste flush,’ uses a larger volume of water to effectively wash away solid waste, such as feces. Depending on the type of toilet, you can remove liquid and solid waste by pressing dedicated buttons or using a dual flush valve lever.

Pros and Cons of Dual Flush Toilets

Dual-flush toilets use less water for flushing and are a great way to conserve water in your home. The cost difference is unlikely to be significantly to standard toilets and if you are switching to a dual flush, you’ll find it is a great way to save on your utility bill, which should offset the cost over time. The only drawback really is that there is slightly more complexity in the design, but they are designed well, they are very common now, and are unlikely to cause issues.

There really are not many disadvantages to dual flush toilets, but here are some pros and cons of a dual flush for you to consider:

Pros:

    • Water Conservation: This is obvious. dual flush toilets consume less water per flush than traditional toilets because they allow you to choose between a high-volume powerful flush for solid waste and a low-volume flush for liquid waste.

    • Cost-Effective: Because dual flush toilets help you save water, they concurrently reduce your water bills over time, saving you money. Assuming you are connected to the utility supply of water, installation costs will over-time be outweighed by the water savings.

    • Positive Environmental Impact: Installing a dual flush toilet will save a considerable amount of water and, as with any water saving measure, will reduce your environmental impact. Water is a precious resource! This is recognised with the EPA watersense label on the majority of dual flush toilets.

    • Regulatory Compliance: Because dual flush toilet systems are notably water efficient, they are often favored in regions with stringent water regulations, ensuring compliance and presenting incentives and rebates. You can check with your local requirements to see if you’re entitled to any benefits.

    • Versatility: Dual flush toilets come in various designs and sizes, offering you the freedom to choose a model that best suits your bathroom’s layout and interior aesthetic.

Cons:

    • Maintenance Challenges: Most dual flush toilets feature more components than traditional toilets. This has the potential to cause more complicated maintenance, should that be required. Thankfully, most dual flush toilets are exceptionally reliable, and may come with a warranty.

    • Retrofitting May Not Be Possible: The toilet flusher, whether it be one button or two buttons, is typically integrated into the toilet cistern. As such, it may be difficult to retrofit a toilet that uses two buttons, or a lever, into your existing setup.

Consulting with a reputable plumber before installing your dual flush system will help you confirm the compatibility of your home’s existing plumbing system and identify any necessary issues that might arise.

6 Types of Dual Flush Toilets

1.    Two-Button Dual Flush Toilets

These are the most common dual flush toilet systems, simply featuring two easy buttons. One button provides a high-volume flush for solid waste, while the other has a low-volume flush for liquid waste.

2.    Dual Flush Valve Toilets

Unlike two-button flush toilets, which feature two distinct flushing buttons, the drop valve system has a singular, dual flush valve positioned on the top of the toilet tank. This enables you to control the flush volume through the positioning of the dual flush valve.

By moving the valve to its corresponding position, you can choose between a partial flush for liquid waste and a full flush for solid waste.

3.    Electronic/Smart Dual Flush Toilets

Leveraging innovative technology, these ultra-modern toilets feature electronic controls, such as touchpads and contactless sensors. When using these toilets, you can choose between multiple automated flushing options and customizable flush volumes.

4.    Pressure-Assisted Dual Flush Toilets

Containing an air-tight tank, these powerful toilets harness pressurized air to support the flushing power, boasting efficient waste removal and therefore reducing water consumption even further! Because these toilets utilize air pressure to force waste out, they additionally present a lower risk of blockage.

6.    Retrofit Dual Flush Conversion Kit

These handy kits save you the expense of purchasing an entirely new dual-flush toilet by enabling you to convert your single-flushing toilet. These kits often feature a dual flush valve mechanism that is used to replace the original flush valve in your traditional toilet.

Of course, you’ll need to check compatibility with your existing toilet.
