To understand the pressure-assisted toilet, you must first be aware of the fact that the toilets you mostly see on a daily basis are known as gravity-assisted toilets. Gravity-assisted toilets are your standard home toilets. They operate via a handle which triggers a valve inside the tank to open and suction the water down from the tank, through the toilet bowl, and into the pipes below. On the other hand, pressure-assisted toilets are a newer technology. They consist of a sealed cylindrical tank inside of a larger ceramic tank. When these toilets are flushed, water displaces the air inside the sealed tank, which generates a much more forceful flush that can be produced by gravity alone. Below are some reasons you may want to consider purchasing pressure-assisted toilets for your home:
Perhaps the most important advantage of all is that pressure-assisted toilets are more water-efficient than their gravity-assisted counterparts. Pressure-assisted toilets use 1.1 to 1.2 gallons of water per flush, as opposed to the 1.3 to 1.6 used by even the most environmentally friendly gravity-assisted model.
