Faucet Rate Problem

Research on the Internet the standards for water flow rates for bathroom faucets in the United States. You should find that the maximum rate should be about 0.5 gallon per minute.

  • Test some of the faucets in your school or home.
    1. Turn the fixture to its fully open position.
    2. Place a container under the fixture and collect the flowing water for 10 seconds.
    3. Measure the quantity of water in the container.
    4. Convert the measurement to gallons. Use the conversion factor 1 gallon = 16 cups.
    5. Multiply the measured quantity of water by 6 to calculate the flow rate in gallons per minute (for example, 0.25 gallon × 6 = 1.5 gallons per minute).
  • Do the faucets you tested have standard flow rates?
