Installing low-flow faucets, toilets, shower heads will help you preserve water during a drought. These types of faucets use about half the water of older models. Low-flow toilets use as little as 1.6 gallons per flush, while a standard toilet may use between 3.5 to 7 gallons per flush.
Look for the WaterSense label which indicates the faucets are 20 percent more water efficient than the standard faucet. They use a maximum of 1.5 gallons per minute, compared to the standard flow of 2.2 gallons per minute.
