A siphoning device used to attain the desired level of water in a swimming pool or other like pools of water that are either overfilled from rain water or from overfilling. A small simple plastic tubular device that is designed to connect to a regular garden hose and hang over the pool edge. A vertical soft plastic threaded tubular pick-up pipe exhibiting threads on one end connects into a vertically aimed threaded fitting of the device and extends into the water to be cut-off by user with a knife at the point that represents the users desired level of water for the pool. Upon filling of the garden hose with water and creating a natural gravity siphon action by locating the termination portion of the hose at a point in the yard that is horizontally a few inches or more lower than the desired pool level, water will be pulled or drained through the siphon device until pool water level reaches the level of the soft plastic pipe cut-off. At which time, the introduction of air into the hose will cease the siphon action and likewise the pool will not be drained any further.
