    IAPMO R&T Grants First EPA WaterSense® Water Closet Flushometer Listing to TOTO

    Ontario, Calif. – IAPMO R&T, North America’s premier third-party certification body for plumbing, mechanical, and water treatment products, is pleased to announce that TOTO has become the first company to gain IAPMO certification of its high-efficiency flushometer valves and commercial water closets to the U.S. EPA’s new WaterSense® Specification for Flushometer-Valve Water Closets.

    TOTO has successfully obtained a listing on its EcoPower Flushometer Valves and Commercial Flushometer High Efficiency Toilets.

    “The EcoPower Flushometer Valves are engineered to generate their own power and avoid dependency on AC power or routine battery replacement, therefore saving energy and water while providing maximum performance in the most demanding commercial environments,” said Fernando Fernandez, Director of Codes and Standards for TOTO. “Certification to the WaterSense specification raises the bar of performance and is a value-added approach to water efficiency. This is why we have chosen to certify our commercial bowls and EcoPower flushometers to the program.”

    In December, IAPMO R&T earned approval to provide independent certification to prospective WaterSense-labeled models that meet the EPA’s water-efficiency and performance criteria, ensuring “both sustainable, efficient water use and a high level of user satisfaction with flushing performance.”

    IAPMO R&T has been a licensed provider of WaterSense certification since 2007, certifying the first high efficiency-toilet (HET) to the standard in April of that year. To date, IAPMO R&T has certified thousands of lavatory faucet, urinal, and showerhead models to the WaterSense specifications. Products bearing the WaterSense label must not only save water, but also perform as well as or better than conventional models on the market.

    “We are pleased that TOTO has chosen IAPMO R&T to serve its expanding WaterSense certification needs, and are committed to remaining the industry’s premier choice for this valuable program,” said Anish Desai, Vice President of Product Certification for IAPMO R&T.

    Manufacturers wishing to have their flushometer-valve water closets identified as meeting the WaterSense criteria by bearing the WaterSense label must have them certified as such by an approved third-party certification body such as IAPMO R&T, which is accredited by the American National Standards Institute (ANSI) and is an approved provider of certification services to WaterSense specifications.

    The IAPMO Group offers an extensive menu of services — product testing and certification, code and standard development, training and education — offering clients worldwide one-stop shopping for all of their plumbing, mechanical, and solar needs, all with fast turnaround and industry-renowned customer service.
