ABSTRACT:
A liquid tank has an outlet opening and a drain stub extends therefrom and has a circular-sector-shaped partial flange on its free end. At least one complementary flange adjoins and complements the partial flange to form a complete first circular flange. The complementary flange may be another partial flange with a throughhole connected to another tank, or a solid blind flange. The first circular flange is sealed and secured to a second circular flange connected to a single drain line. The two circular flanges may have the same diameter and the same aligned circle centerpoint. This provides a modular reconfigurable system allowing a selected plurality of liquid tanks to be connected to a single drain line through the flange arrangement.
