Pressure-Assisted Toilets: Weighing the Pros and Cons


Pressure-Assisted Toilets: Weighing the Pros and Cons

While many folks have run across pressure-assisted toilets from time to time, few actually know how they work. For years, these efficient toilets were only found in commercial settings, however, as a new emphasis on water conservation has increased, the ultra-efficient toilets are becoming more popular in residential applications. The following post will explain the basic operation of a pressure-assisted toilet as well outline its pros and cons.

How it Works

The main difference between a pressure-assisted toilet and its counterpart, the gravity flow toilet, is found in the tank. Gravity flow toilets rely on water and the earth’s gravitational pull to empty the toilet bowl. A pressure-assisted toilet uses a secondary tank, located in its main toilet tank to create additional air pressure to aid toilet flushing while maintaining more water in the toilet bowl.

Pros of Pressure-Assisted Toilets

  • The toilet is exceptionally stronger than traditional, gravity flow models and flushes more waste using less water.
  • Since the bulk of water is located in the bowl, these toilets stay cleaner, reducing the amount of cleaners and labor to keep the toilet clean. Not only can you save a few dollars andsome hard work, but you’ll also reduce the amount of chemicals entering the environment.
  • Since the two-tank system reduces condensation and sweat, it will not contribute to increased humidity in your bathroom.
  • Due to its powerful flushing action, a pressure-assisted toilet will clog less often than gravity flow models. This benefit can be especially helpful in older homes with dilapidated sewage lines that are subjected to frequent clogs, as the extra power of the flushing action can push waste past sticking points within the sewage line.

Cons of a Pressure-Assisted Toilet

  • Some homeowners frown on the fact that these toilets are louder and produce more sound when flushed versus traditional, gravity flow toilets.
  • Due to their limited use, parts for this type of toilet are harder to find. Many hardware stores and/or home improvement centers do not stock their parts on the shelf, requiring you to special-order them or visit a plumbing supply house.
  • Pressure-assisted toilets cost significantly more than traditional gravity flow toilets.

Before choosing a particular model, you would be wise to discuss the pros and cons of both gravity flow and pressure-assisted toilets with your plumbing contractor to ensure you purchase the right type of toilet for your situation.
