If overwatering, or under watering, your lawn is a concern, install a water timer. It not only helps you create a regular watering schedule, it also helps conserve water. Water timers regulate the amount of water consumed and can comply with municipal watering restrictions. Chapin's 41002 programmable, solenoid drive water timer connects to any outdoor faucet with a ¾" GHT thread. Install it outside to control sprinklers or irrigation systems in your garden and yard. The easy-to-read LCD screen, with dust cover, displays start time, duration and battery life. The large dial allows you to quickly turn the unit on and off, set the clock, and start time, duration and frequency. A rain and moisture sensor allows you to skip watering on rainy days or when your soil is too wet. Always use clean freshwater with this unit between 34° and 140° F (1° C to 60° C).
