Pros and Cons of Gravity and Pressure Assist Toilets

Jan 04, 2019  |  By Brham Trim (Lethbridge)  |  Toilets


When the time comes to replace your toilet, you have a variety of options to choose from. One such choice is whether you want a gravity or pressure-assist toilet.

Gravity toilets – perhaps the most common in many homes – utilizes a tank situated behind the seat that releases water down into the bowl through a valve that subsequently pushes the waste into the pipes.

In comparison, pressure-assist toilets have a highly-pressurized tank of air and water behind the seat that, when flushed, ejects this compressed water into the bowl, pushing the waste away. This high pressure flushing helps to prevent clogging and generally requires a little less water, but also produces a high volume noise. The special tanks also must be replaced at least every 10 years, and are more expensive than gravity toilets.

At the end of the day, the choice to use a gravity toilet or a pressure-assisted model comes down to personal preference. We encourage customers to weigh water-usage, maintenance costs, and noise before making the decision.
