Solely at the sink and in the shower, the average person uses 50 gallons of hot water a day.
If you don't already have them, simply by installing a faucet aerator on your kitchen and bathroom sinks can save $50 a year for a typical family of three and a significant amount of water. If you can reduce the amount of water you use while washing dishes, brushing your teeth and shaving, these costs can grow even more.
A faucet aerator adds air to the water, providing the same amount of water pressure as you had before, and you won't notice that less actual water is running.
What You Should Know
- A typical sink faucet uses 3 to 4 gallons of water per minute, although federal guidelines require any faucets made after 1994 to have a maximum flow rate of 2.2 gallons per minute. A faucet aerator can reduce this to 0.5 gallons per minute! In other words, rinsing dishes for five minutes with a faucet aerator as opposed to an older faucet can save you up to 17.5 gallons of water!
- A laminar faucet, which sprays the water through many parallel streams instead of the whole faucet opening, greatly reduces water usage at your sink while rinsing just as forcefully.
- Letting hot water run without using it is one of the worst ways you can waste energy, but you shouldn't let cold water go to waste either. So turn off the water while brushing your teeth or washing dishes. If shaving, plug and fill up the sink with water instead of letting it run continuously.
Easy Things You Can Do
Install faucet aerators on all of your sinks. Not sure if you have them? Simply look at where water flows out of your faucet: an aerator screws into the faucet and should state that it uses anywhere from .5 to 2.0 GPM (gallons per minute) on the outer rim (look closely, it's often etched in fine lettering). If you don't have currently have them in your home, aerators cost anywhere from two to five dollars, and you can find them at your local hardware store. They're easy to install, just screw them on.- For the bathroom sink, get an aerator that flows at 0.5 to 1.0 gallons per minute.
- For the kitchen sink, you'll need a bit more pressure so get one that flows at 2 gallons per minute.
- If you wash dishes by hand, be sure to purchase an aerator with a shutoff valve.
Fix leaky faucets. A leak of just one drip every three seconds wastes 30 gallons of water a month! Finding your wrench and tightening the leak takes only five minutes.
