Before we move on to the list of Top-7 best flushing toilet models to buy, let us see what flushing mechanisms today’s most advanced bathroom fixtures use and how they affect the flushing efficiency of a toilet.
Types of Flushing Systems
While the type of flushing mechanism might not be the very first thing that we think about when choosing a new toilet, it is of prime importance as it determines the overall efficiency of this bathroom fixture. Here are several flushing systems that are the most often used in modern toilet designs:
In these toilets, gravity powers the flush, utilizing the weight of water to produce the pressure needed to force the waste into the trapway and further down the drain.
Similar to gravity flush toilets, pressure-assisted flush exploits this natural force too. Additionally, it has a mechanism that utilizes pressurized air to make the water run into the bowl even harder, removing the waste more efficiently and contributing to a cleaner environment.
Due to their eco-conscious design that allows you to use only as much water as you need to flush down the particular waste, this type of flushing mechanism is quickly gaining popularity. Operated by two buttons, the unit lets you opt for full or partial flush and thus consume water more responsibly.
Double Cyclone Flush
Instead of the conventional rim holes, this mechanism uses large nozzles on both sides of the bowl to release water and create a powerful cyclonic flushing action. The design was created and patented by the famous Toto company.

Before buying a new toilet for your bathroom, it is a good idea to learn as much as you can about how different types of toilets and how they work compared to one another to make sure you will not regret your decision in a few years’ time.
This buyer’s guide will steer you through the most crucial aspects of this decision-making process and help you find the bathroom fixture that meets all your requirements and keeps you entirely happy with your choice.
How does flushing toilet work?
All flushing toilets are powered by gravity, which forces water from the tank to go into the bowl and empty it of waste, driven by its own weight. However, some good flushing toilets today use supplemental mechanisms to help gravity do its job more efficiently, for example, by adding air pressure to make the toilet flushing more powerful.
Here is what happens when you flush the toilet:
- A flush toilet uses a flush lever that, when pulled, removes a valve called flapper and opens an outlet pipe through which water from the tank rushes into the bowl using a siphon mechanism.
- Via holes in the rim (or nozzles in Double Cyclone Flush toilets), water from the tank flows into the bowl, washing its contents away down the main drain.
- When the water level in the tank drops, a plastic float here moves towards the bottom and tilts the lever that opens the ball valve, making pressurized water refill the tank and pushing the float up again.
- As soon as the plastic float has reached the correct level, the ball valve shuts off the water supply, and the toilet is ready to be flushed once more.
How to choose the best flushing toilet?
If you are determined to buy a new toilet for your home, there are a few crucial factors to consider first. To make sure you choose well, we recommend taking the following steps:
Think about water consumption efficiency
Water conservation is important for both the environment and your family budget. The majority of easy flush toilets now only use 1.6 gallons of water per one rinse, which is enough to remove the contents of the bowl and prevent clogs.
However, there are options that can be even more economical in terms of water consumption, such as high-efficiency toilets (HETs) and Ultra-high efficiency toilets (UHETs). The strongest flushing toilet today can require as little as one gallon of water per flush. Finally, if you are looking for the golden mean, try dual-flush toilets in which you determine the amount of water used, based on your immediate needs.
Choose the correct configuration for your bathroom
Homeowners today can choose from several toilet configurations available to them. There are one-piece toilets and those that contain a separate bowl and tank. Besides, you can opt for a round-front toilet or get a bit of extra comfort with a unit that comes with an elongated bowl.
The rim height matters too and should be taken into account when the toilet is to be used by multiple users, including the elderly, people with disabilities, taller adults, and kids. Picking the right configuration will ensure that the toilet is easy to use and care for, as well as fits nicely into your bathroom décor.
Determine the right size and rough-in area
Toilets today come in various sizes, so carefully take the measurements of your available bathroom space before you make your final pick. Remember that different toilets have different rough-in requirements. Most units that are bolted to the floor need a 12-inch rough-in area (the distance between the wall and the fixture).
Based on the size of your bathroom, you can also consider products that come with a 10-inch or 14-inch rough-in area requirement.
Pick the right flushing mechanism
While listed fourth here, this is actually one of the most crucial aspects to consider when picking a new toilet. Users have a wide variety of flushing systems available to them that differ in price based on their functionality. You can opt for cheaper gravity flush toilets or pay a little extra and get yourself a pressure-assisted flush unit if you expect some heavy-duty exploitation.
Alternatively, you can try out a sophisticated and powerful Double Cyclone Flush installed in one of the Toto’s models or go green and pick a toilet that offers the dual-flush functionality.
Focus on the design
When you already know what technical characteristics your future toilet should have, it is time to focus on the looks. It should work well with the rest of your bathroom fixtures and blend harmoniously in the main color scheme.
How do I make my toilet flush better?
If you aren’t yet ready to give up on your old toilet and want to do something to make it work better, here are a few things you can try:
- Use a drain snake to remove the tiny clogs in the water line. These clogs may be too small for a human eye to detect, but they are what can prevent the toilet from flushing as effectively as it used to when it was first installed.
- Check the float assembly for damage. When used for a long time, the float assembly inside the tank may go out of order and cause a slow flush. Replacing this assembly part with a new one can solve the problem.
- Check the holes around the rim. Responsible for releasing water into the bowl, these holes may sometimes get clogged, decreasing the pressure of the flush.
Here are some of the most frequently asked questions from users looking to buy a new flush toilet:
How to fix a slow flushing toilet?
If your toilet flushes slowly, the first thing to do is to check for clogging. Clogs may form in the water line or inside the holes located around the rim of the toilet bowl. If clogs are not the problem, check the floating assembly inside the tank, whose malfunction may cause a slow flush.
What is a siphon jet?
A siphon jet is an S-shaped pocket in the front part of the toilet directly pointed into the trapway. For hygienic reasons, it holds extra water in it until you flush the toilet. When the flush is activated, the vacuum action sucks the water from the pocket into the trapway, thus increasing the overall pressure of the flush.
How much water does a flushing toilet use?
The amount of water consumed per flush may vary depending on the type of the flushing mechanism used. Toilets built before 1982 use up to 7 gallons per flush, while the majority of modern units need 1.6 gallons, and the most advanced models use only around 1-1.28 gallons of water per flush.
Why is my toilet not flushing all the way?
If you have excluded clogging and floating assembly damage as the reasons why your toilet doesn’t flush properly, the problem might be with the surface of the bowl. Its quality tends to impair over the years, with tiny cracks and chippings forming on it that hold to solid waste and make you flush repeatedly.
