Types of Toilets

There are mainly two types of toilets: gravity flush toilets and pressure assist toilets.

Gravity Flush Toilets

Gravity flush toilets have existed for over a hundred years.

The flushing pressure in gravity flush systems is created by the water. Under the influence of gravity, the water drops from the tank into the bowl and pushes the waste out via a trapway. A siphoning action completes the flush and leaves the bowl clean. This is the quietest toilet flush system available, because there are no moving parts.

Since gravity flush toilets lack extra moving parts and depend on nature, there is not much maintenance required. A gravity flush system is not the latest type of technology, but it is a very good system that has been a favorite all over the world for many years.

To make modern gravity flush toilets more powerful, toilet manufacturers have made some changes in the design of their products. One way they accomplished this was by making the flush valve larger. They increased its size from 2 inches to 3 inches.


  • Many of the gravity flush toilets do not cost very much.
  • The gravity flush toilets are quieter than pressure assist toilets.
  • Little To No Maintenance. Troubleshooting and replacing parts is fairly simple.


  • Water tanks create moisture and condensation.
  • Some gravity toilets on the market are not good in performance. You need to check out toilet performance reviews to find the one that works the best.

Pressure Assist Toilets

Pressure assist toilets (also known as power flush toilets) have a tank inside that operates similar to a large balloon filled with water. The tank fills up with water and remains there pressurized. When the flush valve opens, gravity and pressure join to create a powerful flush.

As the air in the tank is compressed by the water, this makes a pressure that pushes waste down the line with great force.

Pressure assist toilets are more powerful and less likely to get clogged. The disadvantage of more noise comes with the advantage of greater power.

Early pressure assist toilets had problems with maintenance. As the models advanced, the many of the problems were solved.


  • Pressure assist toilets have a powerful flush and keep the bowl much cleaner.
  • Lack of condensation. The water is stored in the inner tank rather than in a porcelain tank. For this reason, there is no condensation on the toilet’s exterior.


  • Pressure assist toilets are more expensive than gravity flush toilets.
  • Finding parts and repairing the system may prove difficult.
  • Noise level. Pressure assist toilets are noisy.

Note:  The toilets in public restrooms are usually pressure assist. If you want to see how one works and how much noise it makes, just try out a toilet in a public place. You can lift the lid of the tank and see how the tank looks and operates on this type of toilet.

Best Toilet Flushing systems

The industry standard for water usage in a toilet is no more than 1.6 gallons per flush (gpf).

Some manufacturers make toilets that need only 1.28 gpf. These toilets meet the EPA’s standards for a certification. They are labelled with WaterSense. Some toilets that utilize this water capacity are better than others. So be sure to do your homework before buying.

When you are in the market for a toilet, you must consider several flushing systems. The main goal for any toilet is that all waste clears the toilet bowl in just one flush. An extra flush wastes water.

There are three toilet flushing systems to consider:

1) Dual Flush

With a dual-flush toilet, the user can decide to have a full flush or a partial flush.

The tank features two buttons that let you choose full or partial flush. Typically, the full flush is for solid waste and the partial flush is for liquid waste.

A partial flush uses up to 1.1 gpf and does a great job with liquid waste. It saves a lot of water. For solid waste, the user can select the 1.6 gpf option. This is a great way to save money without giving up flush power.

With a dual-flush toilet, you get great performance and keep within the budget. This toilet flushing system is rapidly gaining popularity.

2) Double Cyclone Flushing System

The double cyclone is a new toilet flushing system from Toto. This technology uses just 1.28 gpf yet it is still as forceful as the 1.6 gpf system. Even though this may seem like a small difference, you will definitely see a change in you monthly water bill.

The double cyclone flushing system combines gravity with centrifugal force to clean the toilet. The water moves out of the tank and is forced through two nozzles that circulate water around the bowl while flushing.

No one knows for sure where this type of flushing ranks with the dual-flush systems and the gravity flush systems. One this is for sure though Toto has made a toilet that is a top seller!

3) G-Max Flushing System

Toto continues to provide outstanding quality and performance with the G-Max flushing system. This flushing technology is used in toilets with 3-inch flush valve and 2-1/8-inch trapway.

The toilets with G-Max flushing system remove waste quickly and require little maintenance. They are also quite. Many consider this flushing system to be the best toilet flushing system.

Because G-Max system uses wide 3-inch flush valve and 2-1/8-inch glazed trapway it has greater water flow. It pulls water to the toilet bowl faster and pushes it away with greater force. The powerful siphon jet ensures that the toilet flushes completely and does not allow waste to return. With the following features, G-Max has become an industry benchmark:

  • A wider 2-1/8-inch glazed trapway pulls more water into the bowl at a faster speed. This feature reduces or eliminates clogging.
  • For a faster, less noisy flush, the G-Max uses a 3-inch flush value.
  • To ensure that one flush does the job, the G-Max features a very big siphon jet.


What is a Power Flush Toilet?

The pressure assist or power flush toilets use less water but have more powerful flushing than a standard gravity toilet. There is a sealed plastic container inside the power flush toilet’s tank. This  container is filled with air. When water fills the container, it compresses the air and creates pressure. Upon flushing the pressure releases and forces the water into the bowl very quickly.

Power flush toilets differ from the gravity flush toilets. Their mechanisms are different even though on the outside they look very much the same. The installation process of each does not differ.

How Much Water Does a Toilet Use?

The amount of water released by flushing varies significantly from one toilet to another. Some older toilets can use from 3.5 to 7 gallons per flush. Federal plumbing standards now specify that new toilets have a maximum flush volume of not more than 1.6 gallons per flush. There are also high-efficiency toilets that use up to 1.28 gallons per flush.

Choosing the Best Flushing Toilet – Things To Look Out

What features make a toilet powerful?

There are several essential elements that impact on the toilet flushing power including the trapway size, the glaze on the trapway, the flush valve size, and the toilet flush mechanism.

Look for a toilet with large trapway and flush valve. The trapway and valve size has the most impact on a toilet’s power and performance. Most openings are 2 inch. However, some toilets have 3-4 inch openings. The larger the trapway and valve are, the better the toilet flushing. This factor alone cannot measure toilet performance objectively. However, usually larger trapways mean better removal of waste.

Some toilets have an objective assessment of their flushing performance. Even though it is not listed by all manufacturers, look for bulk waste removal ratings (toilet ratings with MaP) in the toilet’s specs. The manufacturer that receives the best ratings is American Standard. However, other toilet manufacturers are closing in on their ratings.
