Flushometer–Valve Toilets

Water–efficient toilets, such as low–flow toilets, are a great way to reduce household water use.

Flushometer-valve toilets, also known as flushometer-valve water closets in plumbing standards, are typically found in commercial, institutional, or industrial restrooms, in such places as airports, theaters, stadiums, schools, and office buildings. These types of toilets have two main components—the toilet bowl and the flushometer valve.

Smart Flushing

WaterSense estimates that there are nearly 27 million flushometer—valve toilets currently installed in the United States. Approximately 26 percent (7 million) of the old toilets have flush volumes as high as 3.0 to 7.0 gallons per flush (gpf)—far more water than the federal standard of 1.6 gpf. With many of these models reaching the end of their useful life, replacing them with even more efficient toilets that have earned the WaterSense label could result in significant water savings.

WaterSense labeled flushometer-valve toilets, whether single- or dual-flush, use no more than 1.28 gpf, which is a 20 percent savings over the federal standard of 1.6 gpf. WaterSense has also included a minimum flush volume of 1.0 gpf to ensure plumbing systems have adequate flow to function effectively. Facility managers should consult a plumbing engineer if they have questions about using WaterSense labeled flushometer-valve toilets in their buildings. Like all WaterSense labeled products, the toilets are also required to be independently certified for performance to ensure they can handle typical commercial waste loads.

WaterSense Savings

By replacing old, inefficient flushometer-valve toilets with WaterSense labeled models, a 10-story office building with 1,000 occupants could save nearly 1.2 million gallons of water and nearly $10,000 per year. Of those savings, nearly 870,000 gallons of water and $7,600 in water costs per year can be achieved by replacing the toilets in the women's restrooms alone.

If commercial facilities nationwide replaced all of their older, inefficient flushometer-valve toilets with WaterSense labeled models, it could save an estimated 39 billion gallons of water per year. That’s equivalent to nearly one full day’s flow of water over Niagara Falls!

Look for the WaterSense Label!

Water–efficient toilets, such as low–flow toilets, are a great way to reduce household water use.

Whether you are looking to reduce water use in a new facility or replace old, inefficient toilets in commercial restrooms that are wasting water and money, a WaterSense labeled flushometer-valve toilet is a high-performance, water-efficient option worth considering.
