Frequently Asked Questions
The following information addresses questions the U.S. Department of Energy (DOE) has
received regarding the Showerhead Enforcement Guidance
manufacturers or private labelers permitted to sell shower systems under a single model number, where each individual showerhead and body spray in the system complies with the 2.5 gpm standard, but the entire system exceeds 2.5
No. If a shower system is packaged and sold as a single model, the entire system must be tested as a single unit and must meet the regulatory standard of
2.5 gpm. This requirement is consistent with
the maximum flow rate test procedure in ASME/ANSI
A112.18.1M-1996, wherein products must be tested with all standard accessories, which includes all spraying components, and set at the maximum flow level.
May manufacturers or private labelers sell individual showerheads and body sprays that comply with the 2.5 gpm standard, but that can be installed by the user into a complete system that exceeds the 2.5 gpm standard?
Yes. The DOE regulations apply only to the manufacture and sale of showerheads, not to their installation by the user. A particular model sold as an individual showerhead must be tested and
rated individually and must be capable of operating as single component, even if it can be installed in a larger system by the user.
DOE does not regulate the manner in which products are used or installed
after the point of sale, or the design of shower systems comprised of individually purchased components.
