Abstract: An automatic watering system for decorative plants which has adjustable timing capabilities for providing periodic, unattended watering of plants. It further includes tubing with branching capability so that complex distribution systems that are unobstrusive and concealable may be constructed. It may have check valves and T-sections with built-in valves to prevent flooding. It has a unique monitoring system that indicates an alarm indication in case of flooding or failure to provide water. The system may be constructed as a low pressure system for small installations or a high pressure system drawing water directly from the water mains.
