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

Rated 5 out of 5 by 8 reviewers.
Rated 5 out of 5 by A superb sink drain cleaning tool This machine does everything right. Starting with it's very compact size, this machine is great to use in tight spaces. You can use it in a vertical or horizontal position with no problems. It's pneumatic foot switch frees up your hands and it's power cord is generously long. Although this machine is lightweight, it has a heft and weight that gives testimony to it's high quality construction. The K-40 sets up fast, quickly clears the blockage and its frame allows for cord and tubing storage. December 12, 2014
Rated 5 out of 5 by No Muss, No Fuss Top quality power drain cleaner. Mine has been in use approx. 5 years. I have had no problems in the performance of this model. It is easy to use and effective in clearing most all small diameter drain lines. RIDGID provides top quality professional tools for the industry. December 1, 2014
Rated 5 out of 5 by Glad we made the upgrade! Considering that we are dealing with antiquated drain lines in our 85 year old building, we used to get plenty of slow or stopped drain calls. After taking this through almost every hotel room and easily clearing the hard to access drum traps for the tubs and pedestal sink drains our call volume has dropped off and we can focus more time on other projects. We are very pleased to have added this machine to our already extensive Ridgid tool assortment. Great product! November 25, 2014
Rated 5 out of 5 by This product is portable, easy to operate My Grandfather sold wholesale plumbing supplies since the 50's, and he highly recommended his RIGID products. Recently, I had to snake a secondary sink located in a laundry room. Any plumber knows these types of cement sinks can have all kinds of problems. I pulled out his old K-40 and thought I would have a job ahead of me, but it came through without a hitch! If and when the RIGID tools he swore by ever give out, I'll gladly be back to buy from the newest generation of the same line that has served this plumber's family so well for so long! I'd buy any RIGID product with 'my eyes closed' ... that's the kind of confidence I have in their products! November 25, 2014
Rated 5 out of 5 by love because you never touch the cable hands always stay clean This drain snake is pretty light for the size and the features it has. The power is incredible for the size. The auto feed feature works great which results in a clean hands and work area less cleaning up after the job been completed. I also like the fact that the cord it comes with is pretty long no need for a extention cord must of the time. Another cool thing is for most drains you dont need to take the ptrap off you could snake a lavortory right threw the drain without removing the trap. November 24, 2014
Rated 5 out of 5 by My husband loves my husband loves his especially my long hair clogs the sink drains all the time lol works great and fast November 24, 2014
Rated 5 out of 5 by The Best! The best drain cleaning tool out there! Our bathtub was clogged and we tried EVERYTHING. This was the one thing that unclogged it and it's been unclogged ever since. It drains better than it did when we bought the house! November 24, 2014
Rated 5 out of 5 by Better than a Pistol Rod I really like the fact I do not have to hold the machine with one hand while guiding the cable in to the drain. This machine has plenty of power to clear tubs, sinks, and even urinal drains. May 12, 2014
