Dual flush – Technology and Difference

| by Kerovit

Have you ever wondered why there are two buttons on your flush tank?

However, except for two buttons, it looks similar to an ordinary toilet, but there is a difference. That is Water Saving!

The main difference is that there are two different buttons on this flush tank. Saving water using the least required quantity for flushing depends on the type of waste you want to flush. The trapway, or the opening at the bottom of the tank, is comparatively larger in dual flushes compared to average flushes because a bigger space means more water pressure and less chance of clogging.

Have you ever realized that regular flushes use the same amount of water and time while flushing solid or liquid waste?

This dual-flush technology is for water-saving. Dual flush means that you have two different mechanisms; for the liquid waste, you need less water; thus, you can use the smaller button or half flush. Similarly, you need more water for solid waste and use the bigger button or full flush. With this, you can save about 1000 gallons of water every year.

Although the primary purpose and principle are the same, they are designed to flush out the waste to the drain, and the difference is in the mechanism. Dual-flush toilets use a unique flushing mechanism that helps regulate the water needed to flush liquid or solid waste. 

In dual flushing, what is a siphon, and how does it work?

Toilet siphons, also known as flap valves, are one-way valves designed to boost flushing by using the natural force of siphoning. Because the toilet siphon works as a one-way diaphragm, it pushes water up and down.

The siphon draws water by pressing down on the button, which then passes through a folding diaphragm washer before emerging from the siphon outlet. Gravity then takes over, drawing out the remaining water until the cistern is empty.

In a dual flush, a Full flush works the same way as any regular flush, but there is a different mechanism for half flushing. The water suction is broken midway through the process in a half flush. Another type of siphons accomplishes this when the half flush button is pressed. 

This siphon valve has four extruded cuts around the bottom section of its stem that allow air to enter the valve, breaking the air-tight seal at the midway point of a flush, making it 50% more effective.
