Mighty Pump gives contractors an easy way to remove blockages from A/C condensate drain lines, without the need for electricity, nitrogen tanks or expensive gas cartridges. Made of heavy-duty molded PVC, this lightweight, re-useable pump generates enough pressure to quickly clean slime, mold and dirt plugs from primary and secondary condensate drain lines. It's a reversible, hand-operated pump that can be used to vacuum or push-out a clogged drain line.
