Don't let the faucet run while cleaning vegetables. Just rinse them in a stoppered sink or a panful of hot water. Check faucets and pipes for leaks. Leaks waste water 24 hours a day, seven days a week and often can be repaired with only an inexpensive washer. Even the smallest drip from a worn washer can waste 20 or more gallons a day.
Large leaks can waste hundreds of gallons.
Check toilets for leaks. Put a little food coloring in the toilet tank. If, without flushing, the color begins to appear in the bowl, a leak is present and should be repaired immediately. Do not use the toilet as an ashtray or wastebasket. Every time a cigarette butt, facial tissue or other small bit of trash is flushed, five to seven gallons of water are wasted.
