What is the maximum flow rate for a shower head? (alternate wording)

Explanation:
Shower heads are limited by a regulatory cap to save water while still providing a reasonable spray. The standard maximum flow rate for a shower head is 2.5 gallons per minute, typically specified at a testing pressure around 80 psi. That means no shower head should exceed 2.5 gpm. Values higher than that would violate the limit, while a lower rate is simply a more restrictive option. Since the question asks for the maximum allowed, 2.5 gpm is the best answer. The lower 2.0 gpm option is a valid but not maximum flow, and the higher 2.75 gpm and 3.0 gpm options exceed the permitted limit.
