If you"d rather have time to sip lemonade than spend time watering your lawn or garden, start thinking about a Melnor Aqua timer. Here"s how simple it can be: attach the timer to your hose faucet, turn the water on, and set the timer to automatically shut off, after watering from 15 minutes up to two hours. When time"s up, the gentle shut-off valve prevents pipe-banging. That"s it! You"re free to enjoy a frosty beverage on your deck. This water timer is designed similarly to an egg timer, making it exceptionally easy to use. Two-year limited warranty.
