The new version of WaterSense specifications include rain shower products
The U.S. EPA published Version 1.1 of its WaterSense showerhead specification, reflecting recent revisions in applicable standards and enabling rain shower manufacturers to obtain the label for their suitably efficient products.
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.
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.
The new specification replaces Version 1.0, which EPA released in March 2010, and can be viewed in its entirety here.
