Perform an annual maintenance check on your evaporative (swamp) cooler. Check for and fix any leaks you find. Wash only full loads in your washing machine, or adjust the water level to reflect the size of the load. Pay attention to your water bill and become familiar with your water meter—use them to track your water use and detect leaks. Purchase appliances that offer water- and energy-efficient cycle options. Fix leaky plumbing fixtures, faucets and appliances in the house. Show children how to turn off the faucets completely after each use. Locate your master water shut-off valve so that water can be saved if a pipe bursts. Install aerators on every faucet. This could save you as much as 1 gallon every minute you use them. Be aware! Listen for drips and leaks around the house.
