Soap up, then turn the water back on to rinse off. To check for a leaky toilet, put food coloring or a dye capsule into the tank. If the water in the bowl changes color without flushing the toilet, there's a leak. Toilet dams, which are flexible plastic or metal panels, fit inside the tank and reduce the amount of water used to flush the toilet. This saves about 1 to 2 gallons of water with each flush.
Water lawns only when required.
Soaking only when needed is better than daily sprinkling. When operating sprinklers, water in the early morning or late evening to reduce evaporation. Use a container to measure the amount of water to avoid waste that occurs when overwatering. Slow watering, such as that provided by a drip system, is one of the most efficient methods of irrigating plants. Instead of lawns, utilize low water use plants.
