The bathroom is a great place to conserve water! Here's how:
No dripping: Fix leaky toilets and repair dripping faucets—a leaky toilet can waste up to 600 gallons of water a month.
Check for Leaks. To check your toilet for leaks, put dye tablets or food coloring into the tank. If color appears in the bowl without flushing, there's a leak that should be repaired. To check showers and faucets for leaks, read your water meter before and after a two-hour period during which no water is being used. If the meter does not read exactly the same, you probably have a leak. Fixing a leaky toilet saves up to 400 gallons of water per month, while fixing a leaky faucet can save up to 225 gallons per month.
Go Low-Flow: High-efficiency bathroom sink faucets and accessories such as faucet aerators can reduce your standard flow by more than 30 percent, without sacrificing performance. Other areas where you can reduce your water flow include the toilet and shower. Install an aerated showerhead and you could cut water use by up to 70 percent. An old-style, single-flush toilet can use more than three gallons of water per flush; modern reduced-flow or high-efficiency models average a little more than one gallon.
High Efficiency Toilets. If your toilet is from 1992 or earlier, you probably have an inefficient model that uses between 3.5 to 7 gallons per flush. New and improved high-efficiency models use less than 1.5 gallons per flush - that's 60 to 80 percent less than their less efficient counterparts. According to the EPA, over the course of 10 years, one high-efficiency toilet can save a family of four roughly $1,000 without compromising performance.
Displace Water. Here's an old-fashioned trick: Put a plastic bottle or bag weighted with pebbles and filled with water into your toilet tank. Displacing water in this manner allows you to use less water with each flush, saving between 5 and 10 gallons per day.
Turn off the water: Try to remember to turn off the water when brushing your teeth or shaving. You could save up to four gallons of water per minute!
