In this post, I’ll walk you through various aspects of a pressure-assisted toilet in order to help you make an informed purchase decision.

Moreover, I’ll also be throwing light on Kohler’s pressure-assisted toilet to help you clear your doubts before you make a buying decision.

Lastly, I’ll be responding to the queries related to pressure assist toilets in the FAQs section of this post.

So, without any further ado, let’s begin…

What Is A Pressure Assist Toilet?

As the name suggests, a pressure-assisted toilet is one that is very powerful in its operation as well as injects water out of the tank with optimum force.

A pressure-assist toilet falls in the category of a high-efficiency toilet which is known to offer a wide range of benefits which we’ll be discussing in a while.

They use compressed air to flush out the waste in your toilet.

And, as a result, it has great flushing power and could be a viable option for commercial settings.

In simple words, a pressure-assist toilet is a unique blend of power and efficiency.

It consists of an airtight plastic tank inside the porcelain tank where the water is stored.

For increasing the velocity of the outgoing water, a pressure-assist toilet uses both water and pressurized air.

The good news is, a pressure-assist toilet is capable of generating a very powerful flush just by using about 1.1 to 1.4 GPF, interesting, isn’t it?

Increased flushing powerful will make your job easier and less time-consuming when it comes to breaking the larger waste into smaller ones.

I’m also attaching a self-explanatory video for your perusal.

It goes without saying that pressure-assist toilets are designed in such a way that they are able to utilize higher levels of water-based pressure so that any kind of waste can be effectively eliminated directly into the structure’s sewage system.

The water that is used during the flush cycle of a pressure-assist toilet is pushed through with a higher velocity.

In layman’s terms, a pressure assist toilet not only uses less water during the flush cycle but also is highly effective at reducing the likelihood of a clog.

How Pressure-Assisted Toilets Work?

A pressure-assisted toilet consists of an airtight plastic tank inside the large porcelain tank so that flushing power can be improved when compared to other types of toilets.

The unique thing about the airtight plastic tank is that it fills with water between flushes as well as it is designed to trap air inside the tank and increases the air pressure as more water fills in the tank.

In fact, when a pressure-assist toilet is ready to flush, it uses the built-up pressure so that water can be forced out from the tank into the bowl in a very powerful manner and at a much higher velocity.

If you own a gravity-flow toilet then you’ll agree that it lacks such flushing power.

Also, a pressure-assist toilet uses less water per flush when compared to a gravity-flow toilet.

And, the best part is, you don’t have to worry at all about increasing the trapway in size because the flush force is sufficient to break larger waste into smaller parts.

As mentioned earlier, in a pressure-assisted toilet, a smaller tank rests within the main tank, and the former includes a special type of air bladder technology that features both water and air.

The weight of the water compresses the air within the tank.

During the flushing process, the associated pressure forces the water through the system in an effective and powerful way.

Once the flushing cycle is completed, both water and air refill the pressure assist tank in order to ensure a continuous successful cycle each time the toilet is flushed.

To sum up, a pressure-assist toilet is designed with two tanks in such a way that one is placed inside the other which helps in creating compressed air. When you’ll flush a pressure-assist toilet, the air forces water that is within the product down.

What Are The Pros And Cons Of A Pressure Assist Toilet?

Before making a buying decision, make sure you’re well aware of both pros and cons of a pressure-assist toilet.

In this section, I’ll walk you through both pros and cons of a pressure assist toilet in the best possible way I could.

Pros Of Pressure-Assisted Toilets

Let’s have a quick look at the pros and benefits of a pressure assist toilet.

• As compared to a traditional gravity flow model, the pressure-assist counterpart is relatively stronger and also, flushes more waste using less water.
• These toilets are relatively easier to clean and maintain since the bulk of the water is located in the bowl.
• It uses two tank system which reduces condensation and sweat making your bathroom less humid.
• A pressure-assisted toilet will clog less often when compared to a gravity flow counterpart, thanks to its powerful flushing action.

Note: A pressure-assist toilet can be a viable option for older homes with dilapidated sewage lines that are subjected to frequent clogs. In fact, the extra power of flushing can easily push waste past sticking points within the sewage line.

Increased Flushing Power

One of the main benefits of upgrading to a pressure-assisted toilet is its enhanced flushing power.

And, the best part is, it will not increase the amount of water used per flush.

Let’s understand with an example.

You’ll be astonished to know that a pressure-assisted toilet will save you about 0.2 to 0.5 gallons per flush, or 4,000 gallons per year which will result in a reduction in your water bill cost, and as a result, there will be an increased effort on your end in promoting water conservation.

On the other hand, on average newer gravity-flow toilets will use about 1.6 GPF.

A pressure-assist toilet can flush more powerfully when compared to a standard gravity-flow toilet because the former consists of built-up air pressure inside the airtight plastic tank that forces the water out of the tank in an explosive rush.

Pressure Assisted Toilet Helps In Preventing Frequent Clogging

It goes without saying that the enhanced flush power of your pressure-assisted toilet will definitely reduce the need for a second or third flush to clear waste from your toilet bowl.

Moreover, the high-velocity flush also helps in breaking down large pieces of waste and thus, preventing clogs in your toilet and further down the drain line.

In layman’s terms, you don’t need to worry about using a plunger, a drain snake, or any harsh drain-cleaning chemical that may do lasting damage to your plumbing system in case, you’re not using them as per the directions.

May Reduce Cleaning Frequency And Condensation Problems

A pressure-assisted toilet may require less cleaning as strong flush power will remove debris from the inside of your toilet bowl.

Also, the water level in the toilet bowl of a pressure-assisted toilet is higher than the water level in a gravity-flow toilet.

Needless to say, the increased water level will help in keeping the sides of your bowl clean during use.

The thing that I really adore about a pressure-assisted toilet is its ability to deal effectively with clogging problems.

In fact, the plastic tank holds the water so that it doesn’t touch the sides of the porcelain and as a result, condensation can’t form on the outside of the toilet tank.

However, the probability of condensation issues can still occur on the toilet bowl.

Cons Of Pressure-Assisted Toilets

• Compared to traditional gravity-flow toilets, pressure-assisted toilets are louder and produce more sound when flushed.
• They are expensive when compared to gravity-flow toilets.
• The limited uses of a pressure-assist toilet make their parts harder to find. Moreover, you’ll not find their parts stocked on shelves in many hardware stores or self-improvement centers so you may have to order their parts or even visit a plumbing supply house.

Don’t worry, the shortcomings of a pressure-assisted toilet don’t overshadow the benefits for sure.

The increased flushing power that I’ve been bragging about through this post comes with a cost attached to it.

In fact, if you’re on a tight budget then a pressure-assisted toilet may not be the best choice for you as it is relatively costlier when compared to a gravity-flow toilet.

A gravity-flow toilet costs in the range of $100 & $300 whereas a pressure-assisted toilet typically costs in the range of $500 & $700.

Most importantly, a pressure-assisted toilet produces a considerable amount of noise as compared to a gravity-flow counterpart.

Also, finding the parts of a pressure-assisted toilet can be a tedious and time-consuming task as it isn’t as readily available as a gravity-flow counterpart.

Pressure Assist Vs. Gravity

Let’s have a quick look at both toilets so that you can choose the one that not only suits your requirements but also falls well within your budget.

Gravity-Assisted

The gravity-assisted toilets are quite common and have been in existence for ages.

As the name suggests, gravity plays a major role in their functionality.

As soon as you push the handle, a valve opens within the tank and the water falls from the force of gravity.

A siphoning effect is created in the trapway at the base of the toilet as soon as the waterfalls are inside the bowl.

Moreover, the siphoning action moves water and waste through the pipe and into the septic tank or utility sewer pipes.

Following this gravity-induced waste and water removal, a small gushing pipe refills the tank until a float shuts off the flow of water.

In order to keep the water inside the tank and prevent overflow, there is a small overflow tube present in the unit.

The good news is, most homes can accommodate a gravity-assisted toilet.

On the downside, low-flow gravity-assisted toilets can interfere with the installation procedure due to your home’s plumbing structure.

Moreover, low-flush toilets may not flush the waste as efficiently as the other form of toilets.

You may be able to save on the amount of water needed per flush but at the same time, the number of flushes may increase if the first flush will not do its work properly.

Pressure-Assisted

It goes without saying that a pressure-assisted toilet relies on the same gravity but at the same time, assists the force of gravity with additional pressure.

Needless to say, a small tank within the main tank supplies added pressure.

The end result is easily achieved as water displaces air within a sealed cylindrical tank inside the larger ceramic tank.

Moreover, the cylinder is able to generate a larger force through the air inside the cylinder and is either made up of plastic or metal.

Since the air pressure is forced through the tank so you’ll hear a loud whooshing sound.

As compared to other forms of toilets, the pressure-assisted counterparts are known to hold more water and require a minimum water pressure of 25 PSI to operate most effectively, and as a result, are becoming more popular as efficient toilets that can use less water as well as flush more efficiently.

Features to Compare When Purchasing a New Toilet

Let’s have a quick look at some important features that you must compare when it comes to purchasing a new toilet.

Bowl Shape

There are mainly two bowl shapes that you need to consider if you’re planning to make an informed purchase decision.

• Round Bowl
• Elongated Bowl

In general, round bowl toilets are less expensive and also take up less space so it can be a viable option if you’re on a tight budget.

On the other hand, if your top priority is comfort then you can opt for an elongated bowl toilet as it has got more surface area to sit on.

Flushing Technology

In general, there are mainly three types of flushing systems to consider.

• Gravity-flush toilet
• Pressure-assisted toilet
• Vacuum-assist toilet

I’ve said earlier also, the gravity-flush toilet is the most common type of toilet.

As the name suggests, it uses gravity to flush waste.

In fact, as soon as you pull down on your toilet handle, a gravity flush toilet will open the flushing valve, allowing water into the bowl and flushing out the waste.

On the other hand, a pressure-assisted toilet uses air and water pressure to force water into the toilet bowl, flushing the waste.

On top of it, a pressure-assisted toilet is more powerful than a gravity flush toilet and can flush more waste with less water.

Since these toilets can flush waste more effectively so they also tend to leave less water residue in the toilet bowl than a gravity-flush toilet.

Lastly, a vacuum-assist toilet comes with a vacuum tank that is connected to the trapway.

As soon as you’ll flush your toilet, the vacuum tank will create suction and will help suck waste out of your toilet and through the trapway.

These toilets fall in a similar price range to pressure-assist toilets and are on the higher side when it comes to comparing their price with gravity-flush toilets.

The thing that I really adore about a vacuum-assist toilet is its ability to be as effective as a pressure-assist toilet in terms of powerful flushing and making relatively less noise.

Efficiency

In layman’s terms, the more efficient your toilet is the more expensive it will be.

However, the higher the efficiency the lower will be your water bill in the long run.

A toilet’s efficiency is measured by the amount of water it uses per flush.

As per federal regulations, the maximum amount of water that a toilet can use per flush is 1.6 gallons.

Nonetheless, highly efficient toilets like the one that we’ve reviewed in this post use not more than 1.28 gallons of water per flush.

In simple words, when looking at a toilet’s efficiency you should look at the type of flushing option that the toilet has.

Most toilets come with either of the two flushing options mentioned below.

• Single flush toilet
• Dual flush toilet

A single-flush toilet will have only one flushing setting and is known to use the same amount of water for every single flush, which is usually 1.6 gallons in case, your toilet isn’t highly efficient.

On the other hand, a dual-flush toilet comes with two flushing options.

One option is a light flush which uses a small amount of water, and the other option is a full flush.

In layman’s terms, over the years a dual-flush toilet will save you a decent amount of water which can reduce your water bills, interesting, isn’t it?

Well, if you want a high-efficiency toilet then look for a WaterSense label.

WaterSense toilets promise to reduce water usage for toilets by 20-60 percent which is approximately 13,000 gallons of water per year.

Style

In general, three styles of toilet exists listed below.

• Two-piece
• One piece
• Wall-mounted

Out of the three “styles” of toilets, the wall-mounted ones are the least expensive and are considered the most “basic” kind of toilet.

When you install a two-piece toilet, the tank, and the bowl are two separate pieces that are bolted together during the installation process.

One-piece toilets are one, solid piece of ceramic.

These toilets are more expensive than two-piece toilets but come with benefits like:

• One-piece toilets are preferred by house owners because of their sleek and modern look.
• Since it’s one solid piece of ceramic so cleaning it is easy, quick, and less time-consuming.
• A one-piece toilet prevents the leaking risk of running the toilet leaking between the tank and the bowl which isn’t the case with a two-piece toilet.

Wall-mounted toilets are exactly what they sound like, that is, toilets with no base that are mounted to the wall.

They fall into the category of an expensive style of toilets and are typically made out of one ceramic piece like a one-piece toilet.

Add ons

You should also look for some essential addons in the toilet that you’re planning to buy such as adding a bidet, adding lights, adding a drop seat, etc.

Is a pressure-assisted toilet energy efficient?

Quite a few clients of izzysmarthomeguide.com were skeptical about the performance and efficiency of a pressure-assisted toilet just because it utilizes two tanks.

Trust me, it’s not true at all.

The fact is that a pressure-assisted toilet utilizes less water than a traditional toilet as well as enhances the flush pressure so that cleaning can become easy.

In short, if you’re interested in increasing the overall energy efficiency of your home then the best thing that you can do is to replace your traditional toilets with pressure-assisted counterparts.

Will a pressure-assisted toilet save money?

The good news is, a pressure-assisted toilet will save you a good amount of money in the long run.

Unlike, traditional toilets that have many moving parts, pressure-assist toilets have minimal moving parts.

Moreover, maintenance and cleaning cost for a pressure-assisted toilet is also reasonable.

The technologically advanced pressure-assisted toilets force water more quickly than traditional toilets.

In short, installing a pressure-assisted toilet will save on your water bill or your electric bill depending upon whether you’re on city water or a well.

Is a power flush toilet the same as a pressure-assist toilet?

Yes, both are the same.

A pressure-assist toilet is sometimes referred to as a “power flush toilet”.

The working principle of a pressure-assist toilet is based on the fact that it works by combining pressurized water with a certain degree of gravity in order to completely empty the contents of the toilet bowl upon flushing.

In layman’s terms, if you’ve trouble flushing your current toilet then this type of toilet can be a great replacement option for you.

Is a pressure-assisted toilet larger than a traditional gravity flush toilet?

No, a pressure-assisted toilet isn’t greater than a traditional gravity flush toilet system.

A pressure-assisted toilet is relatively smaller and lighter than its traditional counterpart.

Hence, they make an excellent choice for small bathrooms as well as they don’t overwhelm the structure of your home with additional weight.

Does a pressure-assist toilet increase bathroom humidity?

No, a pressure-assist toilet doesn’t increase your bathroom humidity for sure.

In simple words, the double tanks within the pressure-assist toilet are uniquely designed, as a result, condensation doesn’t build up within the bathroom.

Also, it reduces the number of germs and bacteria circulating within the room.

Moreover, the reduction of moisture within the bathroom helps in keeping the room safer and cleaner.

And, the best part is, it is less likely to damage the flooring and other components of your room.

Furthermore, if you’ve got a current issue with excess moisture and humidity within your bathroom, you’ll be pleased to know that it can be quickly resolved, interesting, isn’t it?
