The flush system has been around for centuries and really began to take effect in the 20th century when new technology began to expand.

To remove waste from the toilet, a person would have to manually flush the bowl by pouring water into the bowl or simply throw away the contents in their 'potty'.

Nowadays, manufactures are coming up with new ideas on the flush mechanism and in particular how to save water consumption in a household. Below are the different types of toilet flush systems.

Standard Toilet Tank (Gravity Flush Systems)

This is the most traditional of flush systems. The standard toilet tank works by pulling or pressing a device that stimulates the water to drain from the bowl into the drain pipes and into the sewer.

The components of this type of systems are a siphon which is an s-shaped drain line. This is connected from the toilet bowl to the drain.

The pressure is created in the siphon from when the bowl empties. This forces the contents to get sucked down the drain.

After the waste is drained, the tank then refills with water to the set level inside the bowl. This system consumes the most water with every flush but it is the most standard and affordable design.

Tankless Toilet

This system is similar in design to the standard toilet with the bowl and seat but this type has no toilet tank. The tankless toilet flush is pressure-assisted. They generally come with chrome-plated piping that is exposed if they are installed in commercial properties. For residential properties, the pipework is concealed inside the wall framing.

The tankless toilet is more efficient with water consumption but is more expensive with the initial installation.

Dual Flush

The name of this type of flush system comes from the option of removing liquid waste and solid waste separately.

This design reduces water consumption as the amount of water for liquid waste is less than for solid waste. You are able to choose between a full flush or a partial flush.

This types of toilet flush system styles are considered the most water efficient as the dual button option can reduce water consumption.

Ballock Flush Systems

The name of this system comes from the floating ball, which is called a Ballcock that is attached to a rod. The water level in the toilet bowl is activated by the plunger that is connected to the rod.

When the rod moves, it activates the plunger which then causes water level to fill or empty in the tank.

Flapper Flush Valves

The Flapper Flush Valve works in the same way as the Ballcock flush mechanism with the difference being, there is no ball but a flapper contraption that is connected to a lever.

When the flapper fills with air, it floats when you press the flush mechanism. This action revoves the flapper from its seat and allows water supply to enter the bowl.

With the loweing water level, the flapper will not go back to its position on the seat thus making way for te tank to refill with water supply.

There are other flush toilet types around the world such as

Chemical Toilets

As the name suggests, waste is flushed down from the bowl and to the drain using chemical fluids that are stored nearby. This is traditionaly used on planes and boats.

Composite Toilets

Liquid and solid waste are not flushed down with water, rather it is stored in a sealed container ready to be used for gardening and compost.

What toilet flushes the best?

There are many different types of toilet flush systems and technology. Some are created for convenience and innovation and others are praised for their water-saving efficiency.

It is difficult to find a style and system that ticks all of the boxes and your preference comes down to how you use your toilet, Economical factors as some types cost more to set up.

As well as environmental factors. Talking to your plumbing professional plumber will clarify any questions you have.
