  • Automatic subterranean watering system with refill indicator and gripping mechanism
    Patent number: 9468166
    Abstract: An automatic watering system includes a water storage reservoir and a water feed reservoir positioned elevationally below the water storage reservoir. The water feed reservoir has a plurality of water feed apertures aligned substantially horizontally for allowing water to pass from the water feed reservoir to outside of the water feed reservoir. The water feed reservoir is in fluid communication with the water storage reservoir via a water tube with a biased seal and via an air return conduit which has a float valve. The water storage reservoir is in fluid communication with the refill indicator for indicating a water level present within the water storage reservoir. The refill indicator includes a float body that tracks the water level within the water storage reservoir. The automatic watering system may also include a gripping mechanism positioned near a top portion of the water storage reservoir.
