The EPA’s eagerly anticipated WaterSense label for showerheads was finalized March 4, and manufacturers are now submitting products for testing.
Like WaterSense certifications for lav faucets and toilets, qualified showerheads must meet performance specifications as well as flow rates. Units receiving the label will have a flow rate of 2.0 gpm or less—20% lower than the current federal standard of 2.5 gpm—while also meeting performance-attribute requirements for flow rate across a range of pressures, spray force, and spray coverage. The specifications apply to showerheads and handheld showers, but not to bodysprays. Showerheads and handhelds must be tested by an EPA-licensed certifying body to qualify for WaterSense.
A number of manufacturers are already offering showerheads that combine lower flows with improved performance, which means buyers won’t have to wait long to purchase certified fixtures. The EPA says it expects labeled products to hit shelves as early as mid-April.
