What Is a Pressure-Assisted Toilet? Pros and Cons

Ever found yourself dealing with a toilet that seems to demand multiple flushes just to get the job done?

If this scenario sounds familiar, your household water bill at the end of the month might be potentially higher. 

You may already know a pressure-assisted toilet is a solution for it, and you are likely here to know about it in detail. Just know, in short, that a pressure-assisted toilet not only provides a more powerful flush, it uses less water than any traditional gravity-fed toilet. 

Nevertheless, this toilet offers more than just a potent flush and water efficiency. So, we’ll uncover its numerous advantages in the following discussion.

What is a Pressure-Assisted Toilet?

A pressure-assisted toilet, otherwise known as a power flush toilet, uses both air and water to generate a powerful flush while using less water than an ordinary toilet. Standard toilets use gravity to flush waste, with water from the tank simply flowing into the bowl, thereby generating a siphoning effect to remove the waste.

On the other hand, pressure-assisted toilets use air to force water into the bowl instead of just replying to gravity. In fact, these toilets are more water-efficient than gravity-fed toilets. 

Along with that, these fixtures only use about 1.1 to 1.2 gallons of water per flush, whereas standard toilets release more gallons of water per flush. Even low-flow toilet models typically consume more water, usually around 1.6 gallons per flush (GPF). 

Additionally, the components inside pressure-assisted toilets are made of durable, heavy-duty material, so they last very long compared to the traditional toilet. 

How Pressure Assisted Toilet Works?

Let’s first recap what happens in a regular toilet. When you flush a regular toilet, the water stored in the tank simply falls and flows into the bowl. This creates a siphon effect that pulls waste and water down the drain. 

In this case, gravity does most of the work, and you can easily understand this if you have a basic idea about gravity. But a pressure-assisted toilet doesn’t only depend on gravity; instead, it uses compressed air pressure to forcefully push the water down into the drain. 

In a pressure-assisted toilet, a plastic pressure vessel in the tank draws air into it, which can’t escape because the vessel is airtight. As the water fills more, the air inside the vessel is more compressed.  

When the vessel is full, and the flush button is pressed, the water is explosively forced into the bowl, taking the waste through the drain pipe. With the help of compressed air, the water is poured down with greater velocity than an ordinary toilet so it requires less water to finish the job.

Advantages of Pressure-Assisted Toilet

Here are the benefits of a pressure-assisted toilet:

Water Savings

A pressure-assisted toilet saves water after every flush. These toilets leverage compressed air to increase the velocity of water into the tank. As a result, the toilet can effectively remove waste by using comparatively less water than any standard toilet. 

Standard dual and single-flush toilets use 1.3 and 1.6 gallons per flush. So, a pressure-assisted toilet saves about 0.2 to 0.5 gallons of water per flush, which amounts to 4,000 gallons per year. These savings could make a substantial difference when translated into your water bill. 

Drainline Carry

The drain carry of standard toilets is measured approximately 40 feet down the drain line. This means they are capable of pushing waste approximately 40 feet down the drain line. However, pressure-assisted toilets have a higher velocity and force that can propel contents up to 60 feet. 

A greater drain carry distance means the waste is pushed further down the drain line before it starts to slow down. This reduces the chance of waste accumulating and forming a clog closer to the toilet.

Breaking Down the Clogs

Pressure-assisted toilet power flush can easily break any large amount of waste and drain it away effectively. Consequently, the toilet will be less likely to experience any kind of clogs. So, having a pressure-assisted toilet installed in your bathroom means you’ll rarely, if ever, need to use a plunger or drain snake, unlike with a standard toilet.

Additionally, a high-pressure flush easily pushes away waste. So, users can obtain their expected result with just one flush, unlike with a gravity-assisted toilet, which may require multiple flushes to push waste out of the toilet bowl. 

Effective for High Traffic Bathroom

Pressure-assisted toilets are well-suited for high-traffic bathrooms or restrooms. Their ability to propel waste with greater force and efficiency makes them ideal for environments where there is a constant influx of users. 

The enhanced flushing power of pressure-assisted toilets ensures thorough waste removal and reduces the likelihood of clogs, even with frequent use. This can lead to decreased maintenance requirements and improved overall cleanliness in busy restroom facilities like restaurants, airports, educational institutions, etc. 

Durability

Pressure-assisted toilets are made with more durable material than regular toilets. As a result, these toilets last longer and are more powerful and efficient during flushing. Even some low-flush pressure-assisted toilets can last as long as 30 years. 

Less Cleaning and Maintenance

As pressure-assisted toilet flush is more powerful, there remains no waste and debris in the toilet bowl. The toilet bowl often looks cleaner. Additionally, it uses less water comparatively than others. If the water is hard, the toilet bowl will be less affected by hard water stains. So cleaning frequency will substantially be reduced in comparison to traditional toilets. 

Reduced Condensation

Pressure-assisted toilets offer a notable advantage in mitigating common condensation issues with traditional gravity-fed toilets. Unlike their counterparts, pressure-assisted toilets store water within an airtight plastic tank rather than directly within the porcelain tank. 

This key difference minimizes the contact between water and the porcelain surface. This factor significantly diminishes the likelihood of condensation forming on the exterior of the toilet tank. 

Consequently, pressure-assisted toilets will save your households from unsightly sweat or moisture buildup, particularly during warmer seasons. 

Space Efficient 

Because of its potential benefits in high-traffic toilets, pressure-assisted toilets are often chosen for commercial places. Therefore, these toilets are made to be space-saving. If your bathroom space is limited, you can easily choose one of those pressure-assisted toilets that are space-efficient.

Disadvantages of Pressure-Assisted Toilet

Expensive

With added benefits comes a price tag. Pressure-assisted toilets are no exception. Although a pressure-assisted toilet will save you water bills and make your toilet bowl cleaner, it costs twice or thrice than a traditional toilet. 

A gravity-assisted toilet costs around $120 to $300, whereas a pressure-assisted toilet falls in the range of $500 to $700. Despite these toilets being expensive, the added benefits definitely outweigh the extra cost.

Noisy

Pressure-assisted toilets are well-known for being noisy compared to standard gravity-fed toilets. The flushing mechanism in a pressure-assisted toilet uses compressed air to create a powerful flush. 

This compressed air is what generates a loud whooshing sound when the toilet is flushed. For some people, the noise can be a major drawback when choosing a toilet, especially for bathrooms located near bedrooms or living areas.

Conclusion 

In a nutshell, pressure-assisted toilets offer a powerful flush that can be beneficial for preventing clogs, especially in homes with frequent use or older plumbing. They can also be more water-efficient than gravity-fed toilets. 

However, these advantages come at the cost of increased noise and expense. Additionally, parts for pressure-assisted toilets may be more difficult to find. Weighing the pros and cons will help you decide if a pressure-assisted toilet is the right choice for your home.
