Keeping your lawn hydrated shouldn’t be a full-time job so let the battery operated underground sprinkler timer by Orbit do the work for you! This battery powered sprinkler timer runs on 3-AA batteries (Not Included) which means that you don’t have to worry about above-ground extension cords or burying electrical lines in your yard. Its durable, waterproof casing allows you to bury the battery operated irrigation controller in the ground and easily connect your underground irrigation hoses. You are in control with multiple setting options on the sprinkler timer: choose to water once every day up to once every 32 days, select to water only on even or odd days, and even designate which days of the week you’d like to water your lawn. A budget program setting gives you the option to use less water which can be beneficial during water shortages and droughts. The battery operated sprinkler timer also features a rain delay so that your yard doesn’t get watered in the rain. Change the length of time your sprinklers run from 1 minute up to 4 hours; determine which zones in your yard need more or less water and make those adjustments easily on the battery operated underground sprinkler timer.
