    U.S. EPA Releases Final Specification for Spray Sprinkler Bodies with Integral Pressure Regulation to Earn WaterSense® Label

    U.S. EPA Releases Final Specification for Spray Sprinkler Bodies with Integral Pressure Regulation to Earn WaterSense® Label

    The U.S. Environmental Protection Agency (EPA) has released its final specification for spray sprinkler bodies with integral pressure regulation to earn the WaterSense® label, and IAPMO R&T is licensed by the EPA to certify such products to the specification.

    The IAPMO R&T Lab stands ready to test spray sprinkler bodies to the newly released specification, and the results may be certified by IAPMO R&T, which has been a licensed provider of WaterSense certification since 2007. To date, IAPMO R&T has certified thousands of lavatory faucets, toilet, urinal, showerhead and weather-based irrigation controller models to 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.

    The EPA estimates that WaterSense-labeled spray sprinkler bodies with integral pressure regulation could save a home as much as 5,600 gallons of water annually and $60 per year in water and sewer costs by providing a consistent flow rate in systems operating under high pressure. By installing WaterSense-labeled sprinkler bodies along with a WaterSense-labeled irrigation controller that uses local weather data to ensure that systems water only when needed, an average-size residential landscape with an in-ground irrigation system operating at 60 psi or above can save more than 12,000 gallons of water annually.

    The WaterSense program offers consumers a simple way to make product-purchasing choices that conserve water with no sacrifice to quality or performance. IAPMO R&T has been working closely with the EPA to offer certification of these products to the efficiency standards necessary to earn the WaterSense mark.

    Manufacturers wishing to have their spray sprinkler bodies with integral pressure regulation identified as complying with the WaterSense specification must have them certified as such by a qualified third-party certification body such as IAPMO R&T.

    For more information on having products tested and certified, contact IAPMO R&T Global Sales Manager Brenda Madonna at (909) 472-4116 or by email at brenda.madonna@iapmort.org. For more information on the WaterSense Specification for Spray Sprinkler Bodies.

    Additionally, IAPMO R&T certification experts will be at the Irrigation Show 2017 in Orlando, Florida, from Nov. 6 to 10. Please stop by Booth 865 to learn more about IAPMO R&T’s services.

    IAPMO R&T certifies and lists plumbing, mechanical, electrical and solar products according to established US and Canadian codes and standards, ensuring continuous compliance to such documents. IAPMO R&T is part of The IAPMO Group’s family of companies.
