What are the advantages of opting for a dual-flush toilet?

Environmental concerns and the desire to save energy and natural resources are driving an increasing number of people to make their homes more efficient and intelligent. Ecological toilets are among the available devices for achieving that end. While the first generation was inefficient (problems with cleanliness, clogging, etc.), today’s toilets have evolved considerably, especially in the case of dual-flush toilets.

Reducing the need for water

As a sanitary device, a toilet needs water. Its use weighs heavily on a home’s annual consumption of clean water, especially when it comes to older toilets, which can guzzle as much as 12 or even 18 liters of water per flush. Thankfully, in the eighties, manufacturers began to introduce less wasteful models (6 to 12 liters per flush), which have become increasingly efficient with time.

WaterSense certified and MaP (Maximum Performance) tested toilets consume less than five liters of water per use (single-flush toilet), while the UHET (Ultra High-Efficiency Toilet) models can do what the others do just as well, but with only three liters of water.

Obviously, they cost more. However, according to non-profit organization Écohabitation, low-flow toilets allow significant savings: 18,250 liters of water per person per year, which translates into $218,800 for a city with a population of 30,000 residents. One solution is to purchase what’s known as a “dual-flush” toilet.

If you’re wondering what that is, it’s basically the same apparatus, consisting of a tank, toilet bowl, base and seat, except that it’s equipped with two buttons (instead of the usual handle) and a flushing mechanism that can release more or less water, depending on the power that is selected, according to situation.

Dually advantageous

By design, a dual-flush toilet is more ecological in and of itself, given that current models only require 3 liters of water (for liquid waste) and 6 liters of water (for solid waste) per flush, resulting in an average of 4.3 liters per flush (based on a scenario of two “number ones” and two “number twos”).

You should be aware that there are also ultra-efficient dual-flush models that only consume two and four liters, respectively, per flush. Low-flow, dual-flush and other similar toilets are also very effective when installed in existing buildings with old or outdated plumbing. In fact, according to a recent study conducted by Écohabitation, there’s no significant difference in the evacuation capabilities of a toilet that releases 4.8 liters as compared with those of a toilet that consumes 12 or 13 liters.

A flushing system can rely on gravity (which is quieter) or pressure to release the water into the toilet bowl. In both cases, being able to choose between a light rinse and a more powerful rinse makes users more responsible for their consumption. For homeowners who use a septic system, investing in dual-flush toilets is an especially wise choice, as it gives them greater control over the amount of water in their septic tank, helping them increase the efficiency and lifespan of the system.
