Most Popular 4 Types of Toilet Flushing Systems

In this Types of Toilet Flushing Systems post, we’re going to discuss the different flushing systems and help you understand them better.

Pressure-Assisted flush

This may not be the most popular flushing system in the market, but it is very powerful. Of course, gravity flush is the most popular. Pressure-assisted flushing system uses pressurized air to force water into the bowl. This flushing system is less likely to clog but it is very noisy. But if you’re looking for a very powerful flush, you can bear the noise produced by this excellent system.

Instead of being passive like gravity flushing systems, the more active pressure-assisted toilets are capable of pushing down more wastewater quicker and with extra force. With these toilets, you will never experience double flushes. When these toilets were first introduced into the market, they were difficult to maintain. But the latest models are better and easy to maintain.

Now, the only challenge lies in the noise that they make when in action. The noise can be attributed to the extra force applied when flushing the toilet. This is the only advantage the gravity flush system has over the pressure-assisted toilets. Overall, they are amazing and very powerful. Also, this system uses less water but stays very efficient in performance.

Gravity Flush

This is the most popular type of toilet flushing system in the market. The gravity flush system applies water to make the flushing pressure, which in return forces all the contents from the tank and bowl via the trapway. Finishing the flush is siphoning action which as well cleans the bowl, and since there are no additional mechanics involved, the gravity flush is one o the quietest flushing systems on the market.

The best thing about using a gravity flush over the other types of flushing systems is that there is very little or no maintenance at all. This is because it has no additional moving sections but just the natural flow. The gravity flush system is also the oldest flushing system on this list and many people prefer it over other types of flushing.

To make these toilets to be more efficient, some gravity flush systems have their tank elevated instead of sitting directly to the bowl, in order to increase the distance water has to travel to the toilet bowl and maximize the pressure created. As a result, water from the cistern is forced into the bowl, cleaning it and removing the waste at the same time very effectively. These are the toilets that you will find in most homes.

Double cyclone

This is one of the latest flushing systems on the market. Actually, this system has been introduced by the Toto toilet brand. The double cyclone flushing system utilizes only 1.28 gallons of water per flush, but it still has the power of a full 1.6 gallons per flush. This helps you save on the water bill and to be eco-friendly by using less water.

The double cyclone flushing system is unique in that it utilizes two nozzles instead of rim holes, and with the support of the propulsion system more water is channeled to the siphon producing a more efficient flush. As a result, there is no lost power, and it as well utilizes some gravity flush techniques for it to complete the process. Though, it’s not clear whether this proprietary flushing system is the same as gravity flush toilets or dual flush toilets.

At the moment, Toto is making an effort to popularize this system and they are reaping well from it.

Dual Flush

Last but not least, we’ve got the dual flush system. This is one of the latest flushing systems on the market and its gaining popularity very quickly. This is because it provides consumers with the chance to choose between a partial flush and a full flush. Who doesn’t want to save water? And the dual flush is the perfect toilet for water-saving or getting a lower water bill at the end of the month.

The dual flushing system features a partial flush and a full flush button. The partial flush is ideal for liquid waste in the toilet and uses up to 1 gallon of water per flush. On the other hand, the full or actual flush uses 1.6 gallons of water per flush. All of this is accomplished by just pressing the right button for every type of flush. The flushing system is very powerful and you won’t experience a lot of issues.

The dual flush toilets are becoming very popular. At the current rate, they are destined to pass pressure-assisted flushing toilets and gravity flushing toilets.

Answer: If our flush handle is loose; you can fix it in two different ways. First, reconnect the lift chain or lift wire that links the lift arm from the flapper. And secondly, adjust the handle mounting nut inside the tank. This usually has reverse threads that need the counterclockwise rotation to tighten it.

Question: I have a running toilet, how do I stop it?
Answer: This is one of the most common problems that toilet users face on a day to day basis. A running toilet can either be caused by a flapper that is not sitting well in the opening valve of the flush or because the water level in the tank is extremely high and allows water to flow over the top of the overflow tube and into the tank. No matter the problem, this can be fixed easily. If the flapper is bad, it has to be replaced. But if it’s not, simply return it in position.
