The Underhill International DrainBlaster 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, the DrainBlaster 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.
  • Hose inlet compatibility: available with 3/4" or 1" female hose thread (FHT) inlets — not pipe/NPT threads — for standard garden hose connections.
  • Drain size & applications: ideal for 4"–6" drains, catch basins, boring under sidewalks, cart paths, greens, and bunkers.
  • Locator ready: wire attachment connector lets you use a wire locator to map drain routing while cleaning.

Easy to attach and simple to operate, the DrainBlaster saves time and reduces manual clearing. Choose DN‑75 (3/4" FHT) or DN‑10 (1" FHT) depending on your hose inlet and site needs. Regularly flush the nozzle after use and inspect jets for buildup to maintain peak performance.
