Most homeowners select their toilets on the basis of looks, size, design, water consumption, brand name, and of course budget. But, there’s something even more important. The types of toilet flush systems you choose. They determine how powerfully your toilet bowl clears the solid and liquid waste. A good flushing system can prevent problems such as clogging — making your life easier.

Interestingly, the idea of a flushing toilet has been around for quite a while. Historians believe that modern, convenient flush toilets surfaced when bathroom technology arrived in the twentieth century. And today, a good number of toilets have even advanced to automatic flush systems. 

All in all, we cannot deny the convenience that these different types of toilet flush systems provide us. There are a lot of flushing systems to choose from but ultimately it boils down to user preference. 

Aim of a Good Toilet Flush System

When choosing any flushing system, your goal should be:

  • That the system is able to clear away all the waste in one flush — without having to do it again in a double flush. 
  • Its jets should cleanse the toilet thoroughly. 
  • The flushing should be quick and regenerate in less amount of time. 

Take a look at our full bathroom remodeling guide to cover all the aspects of the process. 

Types of Toilet Flush Systems

There are four types of toilet flush systems that are very popular with most homeowners. You can go through them and make an informed decision about which one fits your style.

1. Gravity Flush

As the name suggests, a gravity flush system makes use of the water to create a flushing pressure. It then forces out everything from the tank and bowl through the trapway. The siphoning action in the flushing cleans the bowl thoroughly. 

Usually, in a gravity flush toilet, water tanks sit directly on top of the bowl itself. Or, you could have an elevated cistern whereby the increase in the distance to the toilet bowl maximizes the pressure.  

Due to its simple structure, and lack of extra moving parts, a gravity flush is one of the quietest flushing systems. Moreover, it’s very easy to maintain too because of the natural flow of things and no-fuss mechanics. 

Despite using the oldest flushing technology, a gravity flush remains timeless with consumers worldwide.

2. Pressure-Assisted Flush

Pressure-assisted flush systems are quite similar to gravity flush systems, but a lot stronger. They have an extra mechanism whereby the water is sent to the toilet bowl with more force. 

Actually, a plastic tank contains an air-filled balloon that’s pressurized every time water starts to refill in the toilet’s ceramic tank. When you flush, the compressed air inside the balloon pushes water into the bowl at a high flow rate. 

The best part is, this system uses less water and is still quite strong. Let’s just say, it uses the same amount of water as a gravity flush but is more effective because of the extra force applied during a flush. As a result, such a toilet is less likely to get clogged. 

However, where there’s pressure, there’s bound to be noise. No wonder, pressure-assisted toilets are louder than other flushing systems.

3. Dual Flush

There’s a good reason why dual flush systems are one of the most popular flushing systems despite being a recent entrant in the field. They have an environmentally conscious design whereby they allow you to choose between using more or less water — depending on the type of waste you need to flush. 

There are two levers or buttons installed on the same toilet unit. You can either make a full flush or a partial flush. The former uses roughly 1.6 gallons of water and is good for removing a mixture of solid and liquid waste. 

A partial flush, on the other hand, uses 1.1 gallons of water. It’s designed for only liquid waste. Today, many countries are opting for a dual flush system in their new constructions because of its impressive water-saving capabilities.

A dual flush toilet saves money and water without sacrificing power — successfully keeping your water bill low. 

4. Double Cyclone Flush

Also known as a tornado flush, this new technology from Toto toilets is quite interesting. The system releases water into the bowl using two large nozzles on either side instead of the traditional rim holes. The propulsion system ensures that more water is directed to the siphon — creating a centrifugal, cyclonic rinsing action that’s really efficient. It even uses some gravity flush methods in order to complete the process.

The high-efficiency flush uses only 1.28 gallons per flush for both solid and liquid waste. Here too, there will be a significant reduction in your monthly water bill.

The Future of Toilets

We understand that flushing systems provide a convenience that’s matchless but they do account for a huge portion of water usage (or wastage!) within a household. 

Fortunately, in 1994, the environment protection act was passed. It stipulated that no newly manufactured toilet could use more than 1.6 gallons of water. Efforts to make these systems more efficient by the United States Environmental Protection Agency (EPA) are ongoing. 

Very soon there will be toilets without flushing mechanism. You will find options that will minimize water wastage. These will include: 

  • Alternative toilets (what you see on boats and airplanes). These chemical toilets use little to no water. The toilets store chemical flushing liquids and waste in containers until they are disposed. 
  • Composting toilets are as unique as they get. They create a usable product from human waste. Instead of flushing, all the waste is trapped in a sealed container. Once it incubates, it’s ready for use in landscapes and gardens. 

Such toilets will be suitable for areas that cannot support proper septic systems or cesspools.

If you’re contemplating installing a new bathroom or replacing an old toilet, remember that a good flushing doesn’t just get rid of the waste but also cleans the inside of the bowl. Therefore, it’s important to choose an efficient, powerful, and low-maintenance flushing system.
