Flush toilet systems have been around for centuries. Although it is unclear who really invented the first usable flush toilet system, several historians agree that modern flush toilets, which truly provide convenience, have surfaced when bathroom technology arrived in the twentieth century.
A significant number of toilets now have automatic flush systems and the sealed “vacuum water closet” like in airplanes and ships, has already been introduced in several countries. Although water consumption for toilet flushing systems is subject for several different arguments, we cannot deny the convenience these toilet flushing systems provide us.
Flush toilets are toilets that, as the name suggests, flush out the bowl contents through a drainpipe to a city sewer system or septic system, unlike waterless toilets or composting toilets that do not have a flushing system.
This article provides you with useful information regarding several toilet flushing systems — their function and application. Here are some of the toilet flushing systems currently available in the market.
Types Of Toilet Flush Systems
Tank Fill Valve Flush System
Tank fill valve flush systems use a ballcock with a plunger which is a mechanism for filling water tanks. It’s basically a floating ball that is attached to a floating rod. The rod moves to activate the plunger in the ballcock’s body to allow and stop water from flowing to the tank.
Flapper-Flush Valve Flush System
This is a toilet flush valve that is opened and closed by a plate hinged at one side. This mechanism is called the Flapper, and it is usually made of plastic and soft rubber. The flapper is connected to a chain hanging down from the flush handle lever and is responsible for allowing and stopping water from flowing to the tank.
Siphon Flush Mechanism
This is a generic flushing system that uses a Bowl Siphon, a key mechanism molded into the bowl and is necessary to create a siphon using water to drain the toilet wastes from the bowl through the trapway and into the septic tank. Most siphon flush toilets use a lever to flush. This lever, when pushed, opens the flush valve and lets water flow into the bowl.
Washdown toilets are another generic flushing systems that, unlike siphon flush toilets, often have large trapways that are not meant to siphon water off the trap. Instead, they use the washdown method where water is forced into the bowl to push the waste down through the trap. Today, washdown toilets adopt dual-flush technology (read more of this later) and pave the way for modern flushing systems that are very popular in the market.
Pressure-Assisted Flush System
This is a powerful flushing system that uses pressurized air to force water into the bowl. This flushing system is excellent especially for large bowls like those being used in public toilets, which handle much more human excretions and foreign objects thrown in the bowl; these toilets need a powerful flushing system, thus, pressure-assisted flush systems are commonly used for them. The downside to this flush system is that it’s very noisy.
Gravity Flush System
This may be the oldest type of flushing system, but it’s also the most popular in the market. Gravity flush systems apply water to make the flushing pressure, which then forces the contents from the tank and bowl into the trapway. There’s a siphoning action at the end of each flush which further cleanses the bowl, and given that there aren’t any additional mechanics involved, the gravity flush, unlike the pressure-assisted flush, is a quieter flushing system.
Double Cyclone Flush System
The double cyclone flushing system is one of the latest flushing systems that were introduced in the market. Pioneered by the known toilet brand Toto, double cyclone flushing systems use two nozzles supported by a propulsion system which allows more water to flow to pass through the tube and produces a more powerful siphoning action for a much more efficient flush.
Double cyclone flush systems are somewhat similar to gravity flush systems as they utilize some gravity flush mechanics to complete the flushing process.
Dual Flush System
Dual flush systems are also one of the latest flushing systems in the market and are quickly gaining popularity. With dual flush toilets, users can choose between a partial flush and a full flush. This provides a bit of a solution to some water consumption arguments as it can potentially save consumers tons of water.
A full flush uses around a gallon and half of water per flush while a partial flash uses less than a gallon of water, which is ideal if the bowl contains only urine. Flushing is done with just the push of a button and users experience far fewer issues with this toilet flushing system than any of the others in this list.
Rear Flush Toilet System
Rear flush toilet systems use a different kind of toilet bowl. It has more to do with bathroom space convenience rather than flushing. However, this flush toilet system deserves to be on this list since it is widely used mainly in European countries. Rear flush toilet systems offer more flushing power than conventional flush toilet systems, and this is often because of pressure-assisted devices which adds more power with every flush.
Rear flush toilets are more compact compared to floor flush toilets. They use very minimal bathroom space which is why many consumers prefer this flush toilet type.
These are only some of the many toilet flushing systems that are available in the market, and it’s safe to assume that a lot more will be introduced to us as our technologies progress further. Indeed, some toilet flushing systems are far superior to others, but regardless of the flush toilet system type we’re using, these flush systems were invented to make our lives more convenient.
