ABSTRACT:
A water heater overflow prevention system is provided including a water heater with a cylindrical configuration having a circular bottom face, a circular top face, and a tubular periphery formed therebetween defining an interior space. The water heater has an overflow pipe connected to the top face of the water heater and extended downwardly adjacent to the periphery of the water heater. Such overflow pipe terminates with an open end adjacent the bottom face of the water heater for allowing excess water from the water heater to flow therefrom. Further provided is an overflow pan including a circular base with a cylindrical periphery integrally coupled thereto and extending upwardly therefrom thereby defining an open top and an interior space in which the water heater and overflow pipe are situated. An aperture is formed in the periphery of overflow pan adjacent the base thereof. Also included is a drainage pipe having a first end coupled to the aperture of the overflow pan for draining the overflow pan of any excess water that may be present therein. Finally, it is imperative that a height of the pan be greater than 1/3 that of the water heater.
