What are low flow faucet aerators? A typical sink faucet uses 2.2 to 7 gallons every minute the faucet is running. Faucet aerators screw onto faucets to control the flow of the water coming out. Low flow faucet aerators bring sink faucets' water use down to 1.5 gallons or less every minute. These values are the "flow rate" of the water the faucet provides and their units are in gallons per minute or GPM for short.
Why use low flow faucet aerators? Whenever we are using hot water, it is not just water going down the drain - energy is being used too. By switching to low flow faucet aerators, there is an opportunity save over 50% on water and energy costs.
Note: Faucet aerators are on bathroom and kitchen sinks. In a bathroom, flow rates of 0.5 and 1 GPM are acceptable. In a kitchen, the absolute lowest flow rate that is usually acceptable is 1.5 GPM. (Think about how long it might take to fill the sink for washing dishes or a big soup pot.) So, be sure you know the flow rates of the faucet aerators in your fundraiser so that you can clearly tell customers where they belong in the home.
Help your customers know if they need the efficient faucet aerators offered in your fundraiser
Look for flow rate inscribed on the outer side of faucet aerator located where the water comes out; it will have a number and then the units GPM standing for "gallons per minute" following the number. Sometimes, it is printed so small that a magnifying glass may be needed. If you can't find a flow rate on the faucet aerator, then perform this easy test: Find a one-gallon container (a gallon ice cream tub works just fine). If the one-gallon container can be filled in less than 1 minute, then the faucet aerator should be replaced.
