Underhill International DN-75 Drainblaster Drain Cleaning Nozzle

Product Description

The Underhill International DrainBlaster DN-75 is a high-pressure, self-guiding hose-end nozzle engineered to clear debris from landscape drains, catch basins, and pathways. Built for turf and hardscape service, it combines durable materials with a focused jet pattern to remove silt, roots, and compacted debris without dismantling pipework.

• Self-guiding two-stage flushing action: a front cutting jet breaks blockages while rear jets flush debris and propel the nozzle upline for deeper cleaning.
• Durable construction: heat-treated 303 stainless steel resists corrosion and holds up to repeated field use.
• Performance specs: minimum operating pressure 70 PSI (operates effectively up to ~100 PSI in typical conditions) for reliable jet force.

Product Highlights

Ideal for 4–6 inch drains, catch basins, boring under sidewalks, cart paths, greens, and bunkers. Easy to attach and simple to operate, the DrainBlaster saves time and reduces manual clearing.
