The Pros and Cons of Pressure-Assisted Toilets

In our experience, one of the biggest plumbing pet peeves that clients have is a toilet with a weak flush. This can lead to unpleasant plunging or multiple flushes just to get the job done. One way to drastically improve the flushing power in your home is by replacing your standard toilet with a newer pressure-assisted toilet.

Choosing Your Perfect Toilet

But before you make the switch, it’s important to understand the advantages and disadvantages of this type of plumbing fixture.

How does a pressure-assisted toilet work?

A standard toilet uses natural gravity to flush waster from the tank to the bowl and then through the drain.

A pressure-assisted toilet works in a similar way, only it adds compressed air that increases the flushing power. If you look inside the tank of a pressure-assisted toilet, you’ll find a special air chamber that is activated when the handle is pressed down to start a flush.


  • Faster, stronger flushes
  • Lower chance of clogs
  • Higher pressure can help keep the bowl cleaner
  • Less condensation coming from the tank when it’s hot or humid in the bathroom


  • More expensive than a standard toilet
  • Louder flushes
  • More difficult to repair and find replacement parts

Is a pressure-assisted toilet right for you?

Traditionally, pressure-assisted toilets have been used mostly in commercial bathrooms to reduce maintenance and clogs. However, more and more homeowners are choosing to have pressure-assisted (or their cousin, vacuum-assisted) toilets in their homes to enjoy greater flushing power. However, it’s important to understand that these toilets are much louder (which can bother some people) and more complex to repair.
