Pressurized Tank Toilet

One variety of low flow toilet that has worked particularly well over the last decade is the pressurized tank toilet. The line pressure of water entering the toilet compresses trapped air within a sealed tank, until air pressure equals water pressure.

When the toilet is flushed, the pressure of the compressed air reinforces the normal gravity flow. Because of this increase in pressure, 1.5 gallons or less can clean the standard bowl, instead of 3.5 or 5.5 gallons.

National consumer magazines test low flow toilets at regular intervals to compare performance in clearing the bowl and conveying solids through normal pipes. In such tests well-designed ultra-low flow toilets of this kind and others are equal or superior to conventional or water-saving toilets in their ability to clean the bowl and move solids through sewers.

For a private comparison of prices and performance of ultra low flow toilets, see Terry Love’s website Consumer Toilet Reports, at http://www.terrylove.com/crtoilet.htm. USEPA endorses no specific product or manufacturer.
