ESCO Green Awareness Practice Test

The 1992 Energy Policy Act set a standard for showerheads and faucets of 2.5 GPM at what pressure?

60 psi 80 psi 100 psi 120 psi

Correct Answer:

80 psi

Explanation:

The standard used for rating showerheads and faucets is set at a specific test pressure so that different fixtures can be compared fairly. The 1992 Energy Policy Act defines the maximum flow as 2.5 gallons per minute when the water supply is at 80 psi. This means a fixture should not exceed 2.5 GPM under an 80 psi supply. If actual house pressure differs, the real flow may be higher or lower, but the rating is based on the 80 psi test condition. The other pressures listed are common in plumbing, but they are not the benchmark used for this regulation, which is why 80 psi is the correct reference.
