Abstract
An irrigation system draining apparatus adapted for use with an irrigation system having a conduit with a fluid source connection, an air inlet, and at least one output port, the apparatus includes a suction device. The suction device has an input port that is adapted to access an interior of the conduit, and to drain fluid from the conduit by suction when the fluid source connection is closed and the air inlet is open. A method of draining an irrigation system includes closing a fluid source connection for the irrigation system, opening an air inlet of the irrigation system, and using a suction device to drain fluid from the irrigation system conduit through the one output port.
