How does a pressure assisted toilet work?
Pressure assisted toilets don’t look much different than traditional gravity assisted ones at first sight. There’s a bowl that’s usually made of ceramic, a toilet seat that’s made of plastic or wood, and a water tank.
However, there’s also a compression tank that’s located inside of the water tank. It allows toilet to use a combination of water and pressurized air for more powerful flushing action instead of relying just on the force of the gravity.
How does it flush?
While the tank is filling up, the air is getting compressed in the cylinder which is usually made of metal and located inside of the water tank.
Once the flushing process starts, the bowl gets filled with water and the pressurized air sucks the waste through the trapway.
This combination generates more force than traditional flushing systems which allows it to use less water while flushing down more waste at once.
Advantages of pressure assisted toilets
- Efficiency. Because combination of water and pressurized air provides more force, more waste can be flushed through the trapway at the same time.
- Less water needed. Because pressure assisted toilets require less water for efficient flushing, they can reduce your water bills at the end of each month.
- Affordable price. Pressure assisted toilets used to be much more expensive than they are today and we have reached the point when they are just about 20% more expensive than toilets with gravity-fed flushing systems.
The final downside that is impossible to overlook is the price. Despite the fact that a toilet with pressure assisted flushing system can cost the same as a toilet with gravity-fed system, it can cost much more on the long run because wherever there’s a unnecessary technology involved, it creates more chances of something to start malfunctioning.
Spare parts of the pressurized air tank are often very expensive and they require more than just basic “do it yourself” skills to be replaced. This means that if something starts malfunctioning, you will spend money on professional plumbing service and you will probably have to wait on factory parts to get delivered.
1. Kohler K-3505-0 Wellworth Classic Pressure Lite
The Kohler is a well known name among consumers, plumbers and homeowners throughout the United States. It’s a company with over 140 years of experience and they have variety of different toilets on the market.
With that said, the K-3505-0 is an elegant two-piece toilet that comes with Kohler’s Pressure Lite flushing system which was designed for bulk flushing performance. Although it has been on the market for over 8 years, it’s still a toilet that offers a lot for the money.
The Wellworth K-3505-0 is a two piece toilet that has the tank and the bowl separated. The trapway is half exposed and could be a little more concealed, but the curvy tank completes its looks into an elegant looking toilet.
The K-3505-0 comes in several different designs to choose from. Most homeowners will probably opt for the standard white while some might prefer biscuit or almond color option.
The K-3505-0 Wellworth features the Kohler’s Pressure Lite flushing system. It has an internal vessel that’s built into the water tank which pressurizes the water and provides exceptionally powerful commercial-grade flush.
One of the main downsides of the pressure assisted flushing system is the noise. These types of flushing systems can get really loud. However, the Wellworth’s flushing performance is very reasonably quiet. The secret is in the advanced noise-mapping that suppresses most of the noise that would otherwise come out.
- Low water consumption – 1.6 GPF
- Pressure Lite flushing system
- Comfort height
- One-year limited warranty
- Exposed trapway
2. Zurn Z5572
The next in line of our favorite pressure-assisted toilets is none other than the Zurn Z5572, a two-piece toilet with dual flush system. It looks similar to the Kohler Wellworth and shares many of its features. The reason why we ranked Wellworth over the Zurn Z5572 is because Kohler toilets have been on the market longer.
The Z5572 looks similar as most toilets on the market. The bowl is elongated which means that it offers more comfort and the height of the bowl is compliant with the standard ADA act.
The trapway is fully glazed, the tank looks elegant, and the pneumatic lever is plated with Chrome finish.
The Z5572 features dual flushing system with EcoFlushTM technology . You can use partial flush which uses 1 gallon of water for flushing down liquid waste, and full flush which uses 1.6 gallons of water for solid waste.
With that said, the partial flush of the Z5572 is often powerful enough even for flushing down solid waste which makes this toilet ultra efficient.
- Dual flush – 1.0 / 1.6 GPF
- 10-year warranty
- EcoFlushTM technology
- Elongated bowl
- The toilet seat is not included
3. American Standard 2462.016.020 Cadet
The third in line is the American Standard 2462.016.020 Cadet. It offers commercial-grade flushing performance and it’s one of the most affordable toilets on our list of pressure assisted toilets.
The Cadet toilet comes in two-piece design which means that the tank and the bowl come as two separate units which need to be mounted together. The bowl is made of vitreous china with Everclean surface and is elongated which makes it more comfortable to sit on. The Everclean surface is less sticky than traditional materials which means that it helps keep itself clean longer.
Unfortunately the toilet seat is sold separately so you will need to buy it as an addition if you decide to buy the Cadet.
The flushing system of the American Standard Cadet uses 1.6 gallons of water per flush which is on the higher side of today’s high efficiency toilets. However if you are switching from an older toilet that uses 3.5 gallons of water per each flush, you will definitely spot the difference on your water bills.
- Water consumption – 1.6 GPF
- Everclean surface
- Elongated bowl
- Commercial-grade performance
- The toilet seat is sold separately
4. American Standard 2876.016.020 Yorkville
The American Standard Yorkville is another two piece toilet that offers pressure-assisted siphon jet flushing action with commercial-grade performance.
It isn’t much different
Just like the American Standard Cadet, the bowl of the Yorkville is finished with Everclean surface that inhibits the growth of bacteria that causes odor and stains. It has a fully glazed 2-1/8-inch trapway and it comes in two-piece design.
The downside of the Yorkville is that it is mounted with four bolts instead of standard two. This makes it more stable, but the two extra bolts need to be screwed into the wall which might turn a lot of people away from buying this kind of toilet.
The pressure-assisted flushing system of the Yorkville uses 1.6 gallons of water per flush.
- Water consumption – 1.6 GPF
- Elongated bowl
- EverClean surface
- Comes with a single year limited warranty
- Doesn’t include a toilet seat
