This could potentially cut your water usage in half. Older faucets can use between 3 and 7 gallons per minute. Low-flow faucet aerators use as little as 1.5 gallons of water per minute.
Aerators can easily be screwed into your existing faucets. Your faucets (most faucets) in kitchens and bathrooms, usually have standard size outlets with threads inside the outlet for screwing in an aerator. If an aerator is in place, it will have writing on the outside of it, telling you what its “rated flow” is. It’s measured in GPM (gallons per minute). If a faucet is to be considered “low-flow”, it’s rated at 2.5 GPM or lower. If it’s already got an aerator and its rate is higher than 2.5, replace it with a low-flow version.
How to install an aerator: It’s simple. Just wrap some pipe compound or pipe tape around the screw threads of the faucet and screw on the aerator. Run the water to make sure there are no leaks. If this causes your faucet to leak from the base, then tighten that area too. This may require a wrench and some elbow grease, but it’s not too bad.
US indoor residential water usage is estimated to average 80 gallons per person per day in homes without efficient fixtures. Installing aerators will save you money and save water.
