The United States Environmental Protection Agency (EPA) has published Version 1.1 of its WaterSense showerhead specification.
The specification has been revised to directly reference ASME A112.18.1/CSA B125.1 where these standards underwent minor revisions concerning testing procedures and marking requirements. The new showerhead specification further updates the spray force test protocol to accommodate rain showers, which were not previously included, and clarifies product packaging requirements for WaterSense-labeled showerheads, according to EPA.
“We are pleased EPA has issued this revision and look forward to assisting rain shower manufacturers in obtaining WaterSense certification for this popular, but not previously eligible line of showerheads,” said Jin Luo, Executive Vice President with IAPMO R&T.
Currently labeled showerheads are unaffected by this revision; it merely seeks to ensure that future showerheads certified as meeting the WaterSense requirements continue to meet EPA’s criteria for efficiency and performance.
