Dual-flush toilets have two levels of flushing - a full for solid waste and a reduced flush for liquid waste. Typically full flushes range from 1.3 to 1.6 gallons and reduced flushes range from 0.8 to 1.1 gallons of water per flush. Dual flush toilet’s combined full and reduced flush volume is approximately 1.28 gallons per flush (gpf). There are dual-flush options for both commercial flush valve applications and for tank-type toilets.

O+M Tips

• Use cleaning chemicals and solutions that are Green Seal certified
• A two-step process should generally be used if cleaning with antimicrobial products. Clean first and then apply the disinfectant. Wait the recommended time before rinsing (usually at least 10 minutes); perform other tasks while waiting for the antimicrobial to take effect. Most disinfectants are not cleaners, and are usually only effective on a clean surface.

End of Life Tips

• If in good condition, toilets can be donated to organizations like Habitat for Humanity that will reuse them.
• To recycle old toilets visit Earth911.com to determine the capacity of local facilities.

For alignment with LEED Standards

• Water Use Reduction: Employ strategies that in aggregate use at least 20% less water than the water use baseline. Toilets with a flush rate of less than 1.6 gpf can contribute to the water use reduction.
