How Does a Dual Flush Toilet Work?

What is a dual flush toilet? A dual flush toilet features a specific flushing mechanism that adjusts the water consumption for different waste types. There are two primary types of dual flush systems including a toilet with a handle-operated mechanism and another with a push button or lever handle-controlled drop valve system.

The dual flush system promotes efficient water usage by utilizing less water for flushing liquid waste, commonly referred to as a “half flush.” On average, most dual flush toilets consume less than one gallon of water per liquid waste flush, contributing to substantial water savings over time.

How Are Dual Flush Toilets Different?

A toilet performs the crucial task of safely disposing of waste. Typically, toilets are designed to handle solid and liquid waste similarly, where the bowl is initially filled with water. Upon flushing, the waste is carried away through the drain, and the bowl is refilled with water.

Conventional toilets do not possess the capability to differentiate between types of waste and they can consume an excessive amount of water. On the other hand, dual flush toilets are designed to be more water efficient by utilizing varying amounts of water based on the type of waste.

Do I Need a Dual Flush Toilet?

Whether you need a dual flush toilet depends on several factors. Dual flush toilets are designed to conserve water by using different amounts of water depending on the type of waste being flushed. If you are concerned about reducing your water usage and water bill, a dual flush toilet may be a good option. However, you will also want to consider your budget and any plumbing requirements or restrictions in your home.

You will also want to remember that proper use of a dual flush toilet is vital to realizing its water saving benefits. While dual flush toilets may require some adjustment, they are an excellent option for those seeking to conserve water and lower their water bills. However, they tend to be pricier and may require more frequent cleaning due to the reduced water flow. To ensure water efficiency, look for the EPA WaterSense label when considering a new toilet.

How Much Water Does a Dual Flush Toilet Use?

When choosing a dual flush toilet, there are two standard options: 0.8/1.28 GPF and 1.1/1.6 GPF toilets. While single-flush 1.6 GPF toilets are still available, they are becoming increasingly rare. However, if you use the 1.1/1.6 GPF toilet only in high volume mode, it becomes a 1.6 GPF toilet. The benefits of dual flush toilets can only be realized when the low water mode is used for every liquid waste flush.

Here is what to know about water usage for your dual flush toilets:

Dual Flush:

  • Two flushes for separate uses
  • Two controls
  • Solids flush: 1.28 or 1.6 GPF
  • Liquids flush: 0.8 or 1.1 GPF

Single Flush:

  • One flush for all uses
  • One control
  • Solids flush: 1.28 GPF
