Abstract

A drain closure apparatus has a catch basin, a drain, a valve and a valve controller operably connected to the valve. The catch basin has a top, a bottom, an opening in the bottom, and first flange extending radially outward from the top. The drain is disposed within the opening of the catch basin, and has a top, a bottom, a second flange extending radially outward from the top of the drain that attaches to the bottom of the catch basin such that the opening of the catch basin is sealed, and a third flange extending radially outward from the bottom of the drain.
