To define "showerhead" for the purpose of determining the acceptable water pressure for a showerhead, and for other purposes.

HR 5042 repeals a 2021 Department of Energy (DOE) rule defining showerheads and reinstates a 2020 DOE definition for determining acceptable water pressure standards. This bill directly affects showerhead manufacturers and consumers by clarifying which regulatory definition applies to water pressure requirements under energy conservation rules. The key mechanism is the formal replacement of the 2021 rule (86 Fed. Reg. 71797) with the 2020 rule (85 Fed. Reg. 81341), ensuring the older definition governs future compliance. It does not change the actual water pressure limits but resolves regulatory ambiguity in existing standards.
