What is Meant by a Dual Flush Toilet?

What is Meant by a Dual Flush Toilet

The dual flush toilet is the one that comes with two different buttons or handles for flushing different quantities of water. The revolutionary ideas around water consumption and conservation lead to the invention of this system in Japan in 1960. The first models included separate levers and an in-built hand-washer, the water from which could be recycled for another use. Over time, they have been widely popularized across the globe. Later, the design was remodeled for more practical use, and the water usage was cut down to 6 and 3 liters from 11 and 5.5 liters respectively. Let us discuss more this bathroom product!

The Work Mechanism of These Urinals

The initial designs of these urinals incorporated a lever system and had to be operated by siphon valves rather than push-buttons. The full flush released water that amounted to about 6 liters. The half flush releases about 3 liters, and can be released immediately after flushing.

The lever system was replaced with the push button system over time. The push-button differed from the lever in the sense that it depended on gravity in terms of waste removal, unlike the siphon valves in the lever system. For dual flush toilets, this was a bonus as the system also saves water. The toilet bowl or cistern has two buttons for separate waterlines. The greater is of about 1.6 gallons, meant for solid waste removal. The lesser button releases 0.8 gallons per flush. High-efficiency dual-flush toilets can easily clean the bowl faster, and better. Most comfortable toilet seats are provided with tipping bucket cisterns that can be operated by rotating the lever.

Single vs Dual Flush Urinals: Comparison

Features Single Dual
Work mechanism One (full) Two (half and full)
Suitability Public use, family use Nuclear family use
Eco friendly No Yes
Maintenance cost Low High
Technology used Old New
Installation cost Low Medium

If you need a toilet for public use, then you should definitely go for the single one. However, for family use, we would recommend you to buy a top toilet with a dual flush. Both are good in their own places, but the dual technology is a bit costlier.

Overall Pros and Cons

Double flush toilets come both with advantages and disadvantages. Today, we are going to share it all with you. Read below!


Pros and Cons
  • They help in saving water. Hence, it is an eco-friendly model.
  • These urinal systems clog less compared to the other systems. Therefore, it is easy to clean.
  • They look very stylish and increase the elegance of the bathroom.
  • The dual flush round toilet comes with a powerful water force.


  • The double flushing toilet is a bit pricey.
  • Installing and cleaning this urinal is a bit difficult.

What to Look For When Buying Dual Flush Toilet?


The three types of dual flushing toilet are:

  • One-piece: In a one-piece dual flush toilet, the tank and bowl are placed in a single unit. These urinals are easy to maintain as they have fewer crannies and nooks. Owing to this, there is much less space for bacterial growth in this model.
  • Two-piece: Here, the toilet bowl and the tank are placed in separate units. This, too, is easy to repair. There are more models of this type on the market, and most of them are available at a low price. This dual flushing toilet is better compared to the one-piece because it has more sizes and higher affordability.
  • Wall-mounted: In both, the models discussed above, the tank and the bowl are visible in the walls. But in this one, these parts are hidden behind the wall. With this system, you can also decide the height between the floor and the bidet toilet seat.

Flushing Technology

Flushing Technology

Flushing technology is one of the most vital factors of the best dual flush toilet. If you choose the pressure-assisted system, it combines the pressure of the water with that of the air. Even though this process is a bit noisy, it helps in saving water and provides effective flushing. Another technology is the gravity system. It works on the concept of gravity by using the weight of the water for the flushing pressure. This system costs less and does not produce much noise.

Water Usage

Most brands manufacture urinals that use 1.6 gallons per flush. There are a few EPA certified brands that produce toilets that use 1.28 gallons of water. EPA Water Sense is a certificate given to those brands that manufacture urinals that use 80% or less than 1.6 gallons of water. You need to check this parameter before buying the product.
