Water-Efficient
                               Flushometer- Valve
                              Toi lets
   To help facilities become more water-efficient, the U.S.  Environmental
   Protection Agency (EPA) has developed a draft specification for flushometer-
   valve toilets to earn the WaterSense® label in the future. WaterSense labeled
   flushometer-valve toilets will be at least 20 percent more water-efficient than
   the current federal standard,  flushing no more than 1.28 gallons per flush (gpf),
   IMPROVING FLUSH EFFICIENCY
   Flushometer-valve toilets, known as flushometer-valve
   water closets in plumbing standards, are typically found
   in commercial, institutional, or industrial restrooms
   located in places such as airports, theaters, stadiums,
   schools, and office buildings. These types of toilets
   have two main components—the toilet bowl and the
   flushometer valve.
   EPA estimates that about 28 percent, or 7.6 million, of
   the 27 million flushometer-valve toilets currently
   installed in commercial and institutional facilities across
   the country flush at volumes higher than the federal
   standard of 1.6 gpf—some as much as 3 to 7 gpf.

   FLUSH WITH  SAVINGS
   Replacing an old, inefficient flushometer-valve toilet
   with a WaterSense labeled model could save a
   business more than 5,400 gallons of water and more
   than $1,000 over the lifetime of the toilet. If all old,
   inefficient commercial flushometer-valve toilets were
   replaced with WaterSense labeled models, we could
   save more than 41 billion gallons of water per year
   across the country. That's equivalent to the amount of
   water that flows over Niagara Falls every 24 hours!

   PERFORAAANCE AAATTERS
   Like all WaterSense labeled products, flushometer-
   valve toilets will be required to be independently
   certified  for performance. In addition to meeting existing
   commercial plumbing codes and standards,
   WaterSense labeled models  must pass additional tests,
WaterSense labeled flushometer-valve toilets will be
independently certified for both water efficiency and
performance.

such as the ability to flush a toilet seat cover.
Research conducted by the Plumbing Efficiency
Research Council in 2012 found that drainline carry
(i.e., the ability of water to remove waste through a
building's drainline) was not a significant concern at
flush volumes of 1.28 gpf.

and performance criteria for flushometer-valve toilets,

LOOK FOR THE LABEL LATER IN 2015
In the future, businesses, institutions, and other
commercial facilities will be able to look for the
WaterSense label on flushometer-valve toilets. For
