Slag reduction pump

The present invention is directed generally toward a modular apparatus for the circulation, filtration, and chlorination of water in an in-ground swimming pool. In more particular, the invention disclosed herein relates to a modular and transportable pool-side unit in which the entire filtration and circulation systems, as well as the lighting and chlorination systems, for the pool are contained. Additionally, the instant invention utilizes a novel traveling main drain, wherein the functions of a conventional pool main drain and an automated pool sweeper are combined. The traveling main drain is moved about the bottom of the pool by the expulsion of water through a single horizontally mounted jet, said jet being free to rotate in a horizontal plane about the central axis of the device and thereby seek another movement direction when the device becomes blocked. The traveling main drain is connected to the modular pool apparatus through a novel hi-directional water conduit, which contains both a pressure and a vacuum water line.
