• For gravity drain installation, drain must have 1/4" fall per foot (2 cm per 1 m) on horizontal
runs to get good flow. A vented tee connection is also required for proper flow. Extend the
vent at least 12" (30 cm) above the drain outlet.
• For optional drain pump installation, refer to the instructions included with the pump.
