An improved drain spout for attachment to a tank, the drain spout being a cast and comprising:
- a distal base connector having a distal face and a proximal face and having an aperture therethrough;
- and
- a flow pipe extending proximally from the proximal face of the distal base connector, the flow pipe having a proximal end, an external surface and a smooth internal surface having an internal diameter, the flow pipe further comprising an open sump having proximal and distal ends and defined by a reduced upper surface and a radiused transition disposed between the reduced upper surface and the external surface of the flow pipe proximate the distal end of the sump and a radiused cup formed at the proximal end of the sump.
