What is the maximum flow rate permitted for a standard shower head?

Explanation:
Shower head flow is limited by federal efficiency standards to conserve water. The cap is 2.5 gallons per minute when tested at 80 psi, so that is the maximum allowed flow for a standard shower head. In practice, the actual flow can vary with supply pressure, but it must not exceed 2.5 gpm at the specified test pressure. Older fixtures could exceed this limit, but current regulations set the maximum at 2.5 gpm, making that the correct answer.
