Purchasing Water-Efficient Faucets, Pre-Rinse Spray Valves, Showerheads, Toilets, and Urinals

Federal agencies are required to purchase U.S. Environmental Protection Agency (EPA) WaterSense-labeled products where applicable. Faucets, pre-rinse spray valves, showerheads, toilets, and urinals are covered under the WaterSense program. The Federal Energy Management Program (FEMP) discontinued its product designations and purchasing specifications for these products to avoid duplicating efforts and to simplify the federal procurement process. However, FEMP continues to offer technical assistance on water efficiency. Learn about water use reduction.

Faucets

Plumbing codes and standards require a flow rate of 0.5 gallons per minute (gpm) for public lavatory faucets and 0.25 gallons per cycle (gpc) for metered faucets. There are currently few products on the market with flow rates lower than these requirements. In addition, there is no documentation that lavatory faucets with flow rates lower than 0.5 gpm and 0.25 gpc perform in a satisfactory manner.

FEMP continues to monitor market and research activity for commercial faucets and, if warranted, will reissue performance requirements and a purchasing specification for this product type. For more information, see Best Management Practice (BMP) #7: Faucets and Showerheads the Energy Cost Calculator for Faucets and Showerheads, and EPA WaterSense.

Pre-Rinse Spray Valves

Version 1 of the WaterSense Specification for Commercial Pre-Rinse Spray Valves went into effect in September 2013. For more information, see BMP #11: Commercial Kitchen Equipment and EPA WaterSense.

Showerheads

Version 1 of the WaterSense Specification for Showerheads went into effect in March 2010. For more information, see BMP #7: Faucets and Showerheads, the Energy Cost Calculator for Faucets and Showerheads, and EPA WaterSense.
