The Hydro-Skimmer by Waterco is designed to provide the most efficient skimming action in the industry. Plumbing connections accept both 1-1/2” and 2” pipe. Adjustable flanges allow for proper fitting in wood and fiberglass installations of varying thickness. An inlet fitting provides an easily accessible connection for a vacuum type cleaner. The patented Hydro-Control Plate is a feature of all Baker Hydro Deluxe, Commercial and Hydro-Pak skimmer systems and is designed to easily regulate the ratio of flow between the main drain and surface skimming to provide a convenient connection point for a vacuum cleaner hose.
