K-40 Sink Machine

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.

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