K-40 Sink Machine & Accessories

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

The Model K-40 Sink Machine is ideal for cleaning small secondary drain lines.


• 1/4" (6 mm) cables best for 3/4" to 1 1/2" (20 mm to 40 mm) lines.
• 5⁄16" (8 mm) cables best for 3/4" to 1 1/2" (20 mm to 40 mm) lines.
• 3⁄8" (10 mm) cables best for 1 1/4" to 2 1/2" (40 mm to 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. It practically eliminates job site cleanup thanks to the patented guide hose two-way AUTOFEED® control. It completely contains the rotating cable and eliminates any waste water splashing or spraying.
