Prior to the National Energy Policy Act of 1992 that limited the flow from faucet aerators to 2.5 gallons per minute, how many gallons per minute would aerators allow?
  1. 12
  2. 8
  3. 6
  4. 3.5
Explanation
Answer: B - Faucet aerators prior to the National Energy Policy Act of 1992 would allow up to 8 gallons per minute (GPM) to pass through the faucet. More recent aerators contain a water-restricting disk or variable-control component in addition to a screen to ensure they meet the 2.5 GPM requirement.
