For 3/4" (20 mm) to 2 1/2" (75 mm) Drain Lines

The Model K-40 Sink Machine is ideal for cleaning small secondary drain lines from 3⁄4" (20 mm) to 2 1⁄2" (75 mm).

  • 1/4" (6 mm) cables best for 3/4" (20 mm) to 1 1/2" (40 mm) lines
  • 5⁄16" (8 mm) cables best for 3/4" (20 mm) to 1 1/2" (40 mm) lines
  • 3⁄8" (10 mm) cables best for 1 1/4" (40 mm) to 2 1/2" (75 mm) lines

The K-40 sits flat on the floor or countertop and also tips onto its back for easy access to sink drains and bathtubs full of water. The K-40 practically eliminates job site cleanup thanks to the patented Guide Hose two-way AUTOFEED®. It completely contains the rotating cable and eliminates any waste water splashing or spraying.

Features

  • 175 W induction motor quietly delivers enough torque to clear even the toughest blockages
  • Premium-quality, compression-wound inner core cable combines strength and flexibility to resist kinking
  • Two-piece “twist lock” drum housing will not dent or corrode and allows easy access to the inner drum and cable
  • Special inner drum design virtually eliminates cable flip-over inside the drum and drum leakage
  • Two-way AUTOFEED advances and retrieves the drain cleaning cable with a simple push of a lever keeping you and the work area clean
  • Includes RIDGID® drain cleaning gloves and operator’s manual
