There are only two kinds of people in the world. The one who sits on the gravity toilet and the rest who sit on the pressure assisted toilet.

Being the common one, it should be no surprise that everyone knows how a gravity toilet works. It is always the mystery that sparks interest.

I’m sure your head is overwhelmed with questions like, “Which pressure assist toilet should I pick?” and, “Are pressure assist toilets better than gravity toilets?”

This article will be your answer.

Ask any plumber about what the most iconic power flush toilet is, and 9 out of 10 plumbers will give you the same answer: “Kohler Highline Classic.”

With the ceramic finish, this model has the so-called “universal look,” which blends into any interior design like a heated knife cutting through butter. The two-piece design makes the whole thing the icing on the cake.

The only thing that deprives this toilet from perfection, is that the it uses 1.6 gallons of water per flush. In my opinion, every pressure assisted toilet should earn itself a WaterSense label, which means that the toilet should only use 1.28 gallons of water or less. However, this toilet is still more powerful than the traditional toilets.

What We Like:

  • Strong flush
  • Able to link to other bathroom appliances

What We Don't Like:

  • Pricey

If Duravit is the synonym of conservation toilets, then Saniflo should represent the strong flush toilets. The most iconic feature of the Saniflo product is the pump installed behind the pedestal. Due to this little plastic box, Saniflo toilets can flush wasteful material with more pressure. In fact, Saniflo’s toilets are best suited for powder rooms, attics and basements.

And if the strong flushing power isn’t enough, the processor of the toilet can be linked to other bathroom appliances, such as the sink or showerhead, or even the washing machine. (Albeit, this model can only link to the sink.) The only thing you should consider before buying it is the size, because many of the customers forget to take the processor’s length into consideration. Lastly, there are round and elongated versions for this model.

What We Like:

  • Pressure Assist flushing system
  • Comfort Height
  • Strong flush

What We Don't Like:

  • Seat and supply line not included
  • Flush like a jet

Another strong product from American Standard. American Standard Cadet brings the best out of the brand. Using 1.6 gallons of pressurized water, AS Cadet forces out waste matter like bullets, killing anything that tries to step in the way on the way to the water pipe.

The specs of the toilet 28.2 x 15.8 x 30.8 inches, is pretty standard. Another advantage of this model is that the installation is easy. Anyone with basic knowledge of plumbing can install the commode like a piece of cake.

What We Like:

  • Higher water level in bowl leaves it cleaner
  • Pressure of flush is stronger and more efficient
  • Tank-inside-tank design eliminates tank sweat (condensation) during humid weather
  • No condensation

What We Don't Like:

  • Loud
  • Rarely sell in warehouse (bolt and gasket)
  • More expensive than gravity-flow models.
  • May seem rare and hard to purchase

Why Should You Choose Pressure Assisted Toilets?

Pressurized toilets are more common in commercial area like restaurants and sport stadiums. The most iconic feature of this type of toilet is the thrust, as powerful as a landslide. The thing is, there’s virtually no difference from the outside compared to a normal gravity-flush toilet. However, if you take a peek inside the cistern, you will find that a plastic drum replaces the normal tank design.

Besides the ability to evacuate the bowl like a storm, another plus side of a strong flush is that the toilet becomes less prone to clogging. This feature itself is worth more than a thousand trophies.

Not only is the pressurized toilet strong in flushing, the water consumption is low on each flush as well. A toilet that qualifies for WaterSense label uses as low as 1.28 gallons per flush. While flushing with high pressure, the flush-mate style of toilets easily breaks the bar with 1 gallon or lower water consumption.

I think it’s safe to say pressurized toilets hit all the criteria of a good toilet.

How it Works?

Gravity toilets have a relatively simple mechanism. You push the lever or the button to open the water valve. The storage water streams down with the force of gravity. Simple, yet effective.

On the other hand, pressure assisted toilets seem complicated at first sight. But once you witness the wizard behind the curtain, there’s nothing that can fool you. Inside the normal toilet tank, instead of a tank full of water, a plastic or metal pressurized drum is placed there.

The main function of the device is to pump the flushing water with air. When a flush cycle ends, the air comes into the tank first. After that, water refills and pressurizes the air. During the next flush, the pressurized air blasts the water out like a bullet.

Final Thoughts on Pressure assisted toilets

Clogging toilets is always the most common household problem. Installing a pressure assisted toilet avoids a lot of trouble beforehand. This type of toilet used to only appear in public places; but recently, there’s a growing population that  is bringing pressurized toilets into domestic use.

Personally, I’m happy for the ongoing trend. The only thing that I feel is the fly in the ointment is the flushing sound. Hopefully, the future technology will fix the defect and makes a better toilet.
