The DiversiTech SG-1 SWOOSH® Big Shot™ is a high-pressure CO₂-powered tool engineered for clearing HVAC condensate and other drain lines without chemicals or water. Designed to deliver up to 800 PSI of oil-free air, this drain cleaning tool uses replaceable 20-gram CO₂ cartridges to quickly and safely dislodge debris and restore flow in 3/8″ to 3/4″ drain openings.
Key Features
