The U.S. Environmental Protection Agency (EPA) WaterSense® program is issuing technical clarifications related to its homes specification and lavatory faucets specification. New clarifications, indicated by their identification number, address:
- HO-1221-1: Requirements for demonstrating that homes adhere to national, state, and local regulations.
- LF-1221-1: Clarifying faucet marking requirements to reference 16 CFR 305.24(a) Labeling and marking for plumbing products, which supersedes the previously referenced section within the Code of Federal Regulations. The updated reference also resulted in changes to clarifications LF-0113-1, LF-0113-2, and LF-1219-1 and the cancellation of clarification LF-1215-1.
In addition, EPA canceled multiple clarifications based on their incorporation into the WaterSense Specification for Weather-Based Irrigation Controllers, Version 1.1, which was published in September.
To help differentiate between “Active” and “Canceled” clarifications moving forward, EPA has established separate tabs within its Compendium of WaterSense Product Specification, Certification, and Labeling Clarifications. As a reminder, manufacturers and licensed certifying bodies must adhere to these clarifications when certifying products to meet relevant WaterSense product specifications.
If you have any questions, please contact the WaterSense Helpline at (866) WTR-SENS (987-7367) or watersense@epa.gov.
