What does this do?
HR 4593 would replace the federal energy law definition of "showerhead" with the definition found in industry plumbing standard ASME A112.18.1-2024. Emergency safety showers, such as eyewash stations in labs or factories, would be excluded from the new definition. The Department of Energy would have 180 days to update its regulations to match the change.
Who does it affect?
The bill most directly affects shower product manufacturers, retailers, and homeowners or builders who install shower systems. People who use or prefer multi-head or high-flow shower setups could face different product availability depending on how the new definition is applied.
Why does it matter?
The current federal definition has been used to apply a single total water flow limit to multi-head shower systems. Adopting the industry standard definition could result in each showerhead in a multi-head system being treated separately, potentially allowing higher overall water use. This may have greater consequences in regions where water conservation is a concern.
