This deluxe automatic water shut-off features a unique dual shut-off function. It can either be set to continually water for up to three hours, or it can be set to a 'soaker' setting. The soaker setting lets the water flow for five minutes, then shuts off for ten minutes, and lasts for the amount of time you set it to (up to three hours). This is a manually-operated timer, so no batteries are required.   Click Here for Watering Tips Click here to find out how you can help conserve water!
