Repairing dripping faucets by replacing washers can also save water. If a faucet is dripping at a rate of one drop per second, then 2,700 gallons of water are wasted per year. While repairing dripping faucets, residents can also retrofit all household faucets by installing aerators with flow restrictors. Residents can also check for toilet tank leaks by adding food coloring to the tank. If the toilet is leaking, color will appear in the toilet bowl within 30 minutes.
Most replacement parts are inexpensive, readily available, and easily installed.
If the toilet handle frequently sticks in the flush position letting water run constantly, it should be replaced or adjusted. In many areas, low-volume toilet units are already required by law. Dozens of businesses are already objecting to stepped-up restrictions, warning of widespread layoffs, closed shops, and monetary losses. Representatives from pool, car-wash, fountain, nursery, sod, landscaping, golf, farming, and building industries are advocating for less stringent restrictions. Dr. Tom Patterson, field director of Polk County-based Christian Disaster Response, said that, in addition to dry conditions, rapid development is also taxing the state's water supply.
