Metering / Sensor-operated


Description

Metering faucets dispense water for a pre-determined period of time. Combined with a high-efficiency aerator, metering faucets deliver a pre-defined volume of water (0.25 to 0.125 gpc - gallons per cycle). Electronic faucets use a motion controlled sensor to activate water flow. They can either be programmed to turn off when motion ceases or based on a pre-determined period of time. Both metering and sensor-operated faucets can use high-efficiency aerators; however, the faucet may cost more than conventional faucets


Tips

O+M Tips

  • For sensor-operated faucets use rechargeable batteries.
  • For metering faucets replace metering cartridge according to manufacturer's recommendations.
  • Use cleaning chemicals and solutions that are Green Seal certified
  • Ensure the flow-restrictor is cleaned to prevent sediment buildup to allow for maximum water flow

End of Life Tips

  • If in good condition, faucets can be donated to organizations like Habitat for Humanity that will reuse them.

For alignment with LEED Standards

  • Water Use Reduction: Employ strategies that in aggregate use at least 20% less water than the water use baseline. Water saving faucets with a flow rate of less than 0.5 gallons per minute GPM or 0.25 GPM per metering cycle can contribute to the water use reduction.
