Functions of Pressure Assist Toilets
Pressure assist toilets are toilets that use a sealed pressure tank which helps contain air.
As the tank fills with water, the air within the vessel is trapped to create pressure via the water supply line.
The result? An ultra-strong push that removes waste in a matter of seconds.
Positives & Negatives
Pressure-assist toilets maximize waste removal and are faster than traditional gravity-flush toilets.
- Reduced chance of clogging
- Capable of using less water
- Require less maintenance
- Superior flushing power
- Tend to be more expensive than gravity flush toilets
- More difficult
to find replacement parts
Efficiency isn’t sacrificed but money is saved! Pressure-assist toilets are more likely to be in a residential bathroom than a commercial one.

Frequently Asked Questions
Which toilets have the most powerful flush?
TOTO, Kohler, and American Standard toilets tend to have the strongest flushes because of their state-of-the-art patented flushing systems. Each brand has a unique flushing mechanism that removes waste without leaving streaks or stains behind.
Pressure-assist toilets use a sealed pressure tank to push air and water through a toilet’s water system while dual-flush toilets simply allow the user to choose between two flushing options, depending on waste size.
What toilet is best for not clogging?
The Kohler Highline Classic Pressure Lite’s sheer power removes waste and water in seconds, without any clogging. Thanks to the toilet’s fantastic pressure-assist flush, the moment you flush your waste, it’ll be the last time you see it.
What is a Sloan Flushmate?
The Sloan Flushmate is a pressurized flushing system that significantly reduces the chance of clogging or backup. Air is trapped in a toilet’s tank and compressed when water from the supply line comes in. Instead of the traditional pull method as seen in gravity flush toilets, the Sloan Flushmate pushes water into the specially designed toilet bowl.
What is a piston cartridge?
Our Final Opinion
Pressure-assist toilets are fantastic, as they’re reliable, durable, and efficient. Though they might be a bit pricier, the investment is well worth it because you don’t have to worry about daily maintenance.
You deserve a worry-free, luxurious bathroom experience. A pressure-assist toilet may be just the addition to your home that you’re looking for.
