A Guide to Pressure Assisted Toilets

When pressure-assisted toilets came out they had to compete with the current king, gravity-feed toilets. It is still an interesting and ongoing competition between the two types, with companies often catering to both by creating models around their strengths. The goal of pressure-assisted toilets is a smaller, more modern take on toilets that is built for commercial use. They gained popularity in business settings for being reliable with multiple users. When residential users also showed interest, consumer based pressure-assisted toilets became a worthy buy.


A Guide to Pressure Assisted ToiletsBrands that manufacture this type of toilet are known for pushing their other types of toilets or appliances. American Standard, Kohler and Zurn are the popular brands for pressure-assisted models. Kohler is the name that you want to pay the most attention to since they are also important within the gravity-feed market. Even with the established pressure-assisted brands, there are still plenty of choices outside of these three companies. Ove Decors and AquaSourceare also notable brands that make good pressure-assisted models. Toto, one of the biggest gravity-feed producers is not on this list. That is by design, as they continue to improve the gravity-feed model to dominate the market.


A Guide to Pressure Assisted ToiletsIt’s no secret that pressure-assisted toilets come with a higher price tag than other types. The tighter mechanics of their design require more complex parts, leading to a build that is higher in overall costs. The premium you pay for a pressure-assisted toilet is worth it for homes with low water pressure, where the flush will still maintain its power. The consistent performance regardless of the home water system is why high priced pressure-assisted toilets pay for themselves quickly. Some of best models on the market are reasonably priced, so it just takes a little bit of research to find a good deal. With enough searching, you can get a high end pressure-assisted toilet for not much more than a gravity-feed model.

Pros And Cons Of Pressure-Assisted Toilets

Pressure-assisted toilets come with a lot of pros and cons, many that come as a surprise to some users. Buyers that need a quick chart to help them decide on the purchase can reference this pro/cons list. All of the essential information below will give you a general idea of why people favor pressure-assisted models, and also why some feel they need to go in a different direction. Although a few are obvious (like price) there is deeper information that explores the features of pressure-assisted models.


A Guide to Pressure Assisted ToiletsPowerful FlushThe pressure of the flush gets rid of waste in one go. It is powerful, fast and does the job without wasting water with a second flush. Even older pressure-assisted models excel in this area, and isn’t too far off from present day models. The power behind these flushes is the main selling point of pressure-assisted toilets, and even with improvements to the gravity-feed design, pressure-assisted still remains the most powerful type.

Better For Humid ClimatesTank condensation is at its worst when the toilet is used in humid climates. Australia, Louisiana, Texas and Arizona are good examples of places that pressure-assisted toilets can thrive. Tank condensation is also known as tank sweat, and in the bathroom where germs and bacteria grow, can be a bad mix. Eliminating tank sweat gets rid of a lot of opportunities for bacteria and germs to grow. Less of both means a longer lifespan for the toilet and surrounding materials in the bathroom.

Cleaner BowlsGetting waste down with the first flush doesn’t mean that the bowl will be clean. Sometimes second and third flushes have more to do with ‘cleansing’ the bowl. Pressure-assisted toilets use a combination of high powered flushing with higher water levels to ensure the bowl remains clean after a flush. Streaks and other materials are not left over after a flush, which is something that is vital in a multiple use toilet.

A Guide to Pressure Assisted ToiletsSmaller/LighterPressure-assisted toilets are smaller than other types, so as a result can be put in smaller bathrooms. This is beneficial for multiple reasons; consumers that need a high use toilet for multiple users sharing a small bathroom will find pressure-assisted ticks all of the checkmarks. There is also the benefit of cleaning duties being less hazardous with the toilet since it gets waste down and cleans the bowl thoroughly in a multiuse scenario.

Low Water ConsumptionLower water consumption saves you money and puts less stress on the pipes. Combine that with less flushes and you have a toilet that was made for homes that want to save money on their water bill. Pressure-assisted toilets are not bothered by low water pressure. Their flush won’t be less powerful since the mechanics of the toilet works hard with the water already in the bowl rather than depending on the quality of the water coming in. Apartments/homes/businesses with a weak water supply line should be fine when using a pressure-assisted toilet.


A Guide to Pressure Assisted ToiletsLess DesignsThe large head start of gravity-feed toilets makes it near impossible for pressure-assisted models to match them in design. Although plentiful, you’ll have less choices in a catalog, something that can be a real problem for buyers that want a specific look. And if you’re trying to match features+the design you want, the options are even smaller.

PriceThis is a well-known con of buying a pressure-assisted toilet. The price will always be higher than a gravity-feed model, even after doing a lot of deep research. You can still get good deals on them, and buyers that are lucky only had to spend a little more than they would have for a gravity-feed model. But trying to find that ‘perfect price’ is one of minor frustrations of going the pressure-assisted route.

NoisyThat extra power comes with noise that is louder than other models. It’s noticeable, so even if the walls aren’t thin in the bathroom you’ll hear it. Pressure-assisted toilets are still a lot less noisy than they used to be, but there is still a long way to go in that department. Right now it is at an acceptable level, with the technology improving on major models so that the next generation is even better.

Expensive PartsPressure-assisted toilets are not DIY friendly. They have complex mechanics that are hard to fix on your own, and getting parts for them is expensive. The latter part isn’t too surprising since the toilet itself has a high price tag, but having the parts follow the same example makes fixes extra expensive. The cost of the parts along with a professional will test your wallet if more than one pressure-assisted toilet is involved.

No Mod SupportOne of the great things about gravity-feed toilets is that they can be modified for better performance. With pressure-assisted the complexity level is higher, leaving a lot of beginner and intermediate users out of the picture. You need to be an expert with professional experience to even consider modifying a pressure-assisted toilet. And even with modifications, the gains are not worth the trouble. Think of a pressure-assisted toilet as a tricked out car that is already pushed to its limit.

Best Features

A Guide to Pressure Assisted ToiletsPlenty of users have positive stories about their new pressure-assisted toilet, with a lot of those users being longtime gravity-feed consumers. The change to these new models has a lot to do with some of the features listed below. While many of them are standard on leading brands, there are a few proprietary technologies that make the price of pressure-assisted well worth it.

  • Pressure-assisted flush is the most powerful flush you can get in the industry on the consumer level. Even on the business side, there is no flush that is this powerful without wasting water
  • EverClean Surface is known to be used by American Standard, but has other names under different brands. An EverClean Surface maintains the integrity of the bowl and protects it from mold, milder and bacteria. Stains or odors that are allowed to grow on other surfaces will not be a problem with EverClean tech.
  • Users can hook up their plumbing faster than ever with Speed Connect. This tank and bowl coupling system saves a massive amount of time during the installation or during repairs. The technology is also used with other appliances in the home that rely on water. Hookup is fast and simple, so once you’ve done it the first time every other appliance is muscle memory.
  • FloWiseis a feature that is included with water saving models. There is no better way to conserve water than with a bathroom toilet featuring this specific technology. The good news is that it is also available on showers, bathtubs and other appliances in the home that use water. A home with a pressure-assisted toilet and other FloWise appliances can save up to 33,000 gallons per year. This feature by itself proves that the high upfront cost of pressure-assisted toilets is just a minor investment.

Why Choose A Pressure-Assisted Toilet Over Gravity-Feed?

A Guide to Pressure Assisted ToiletsNo matter how much gravity-feed toilets improve, they won’t catch up to the power guarantees of a pressure-assisted toilet. And with the water saving technology added to the power, it really becomes a modern marvel in the bathroom. That is why pressure-assisted toilets started out so popular in business and industrial facilities. It is a high cost upfront but a longtime money saver in areas where water bills run high. With the right setup, you could lower the water usage to 1.1 gallons per flush. That is a massive improvement from gravity flush toilets, where the high end models boast about 1.6 gallons per flush. Easy installation options and less clogs round out the last few reasons why pressure-assisted is a wise choice for any home.

How Does A Pressure-Assisted Toilet Work?

A pressure-assisted toilet has a completely sealed tank when looking at it from the top. Once the tank begins to fill with water, the air gets compressed inside the tank. Think of the way an air gun stores air (energy) and then forces out its ammo. When you flush a pressure-assisted toilet, it is doing the same with the water rather than letting gravity pull waste down. That is why the sound is loud when you flush a pressure-assisted toilet. It is literally shooting the waste and water into the pipes while simultaneously spraying the bowl clean. A few models take it a step further and allow the use of a battery or electric pump to compensate for water pressure that is too low. For reference, models exist that can operate from as low as the 20-25 psi range.

Are Repairs Easy?

A Guide to Pressure Assisted ToiletsNo, and this is one of the reasons repairs was listed under cons. Repairs with pressure-assisted toilets are meant for experts or professionals. There are guides online that walk users through the steps of fixing smaller problems with the toilets, but anything that involves taking the tank apart (or replacing a part) is asking for trouble from inexperienced users. Without the proper know-how, it is recommended that consumers avoid trying to fix their pressure-assisted toilets if they run into trouble. If it is under warranty, messing with the tank in any way is an automatic void of that warranty, so be careful.

Cleaning A Pressure-Assisted Toilet

Other than the usual bathroom cleaning, nothing special needs to be done with a pressure-assisted toilet. Maintenance is light, and bowl cleanliness is on the upper tier since they use materials that naturally fight bacteria/mold/odors. Humid climates that use these toilets will do fine, as condensation isn’t a big issue with these models. Just like gravity-feed types, cleaning with popular brands (Scrubbing Bubbles/Lysol/ etc.) should be more than enough on a weekly basis, or as needed. Instead of using a drop in tablet users can buy an on the bowl cleaner since the tank is sealed. Gel stamps are a popular way to keep the bowl fresh and clean without using a drop in tablet.


Pressure-assisted toilets are an expensive but welcome option to any home or business setting. Their high performance and low water consumption turns these toilets an ideal buying choice.
