Rated 5 out of 5 by from Would definitely recommend this This is the most versatile drum machine I have used. Small enough to maneuver into tight spaces and it has enough power to break through everything I have put it up against. The autofeed is a game changer!!!!!

Rated 2 out of 5 by from Could be better Didn’t come with big enough heads and the auto feeder was a lot extra.

Rated 4 out of 5 by from Great machine, bad cable Bought machine on 6/25. Opened box at first job on 6/26. Found small piece of black plastic in bottom of box. Later figured out it was part if the coupling between the drum and frame. I snaked drain one time - paper clog in a 3 inch line. Switched heads and head connector had broken welds at cable (in my opinion heat stress cracks next to welds). Left job incomplete. Took snake in for service. Got it back nearly 3 weeks later - 7/15. Coupling replaced and connector welded back on to cable. 7/18 - Second job for this machine. Another paper clog. Attached head and gave a light test to the weld. Connector cracked next to new welds. I had to remove connector and bend the cable to effectively clear the clog. Now I don't know if I should take it back a second time, just buy a new cable, or fix it myself taking time to preheat and slowly cool the weld to remove heat stress from the cable. I've had a k380, k400, and a k3800 on my service vans for years. I have only broken one other cable. It was on an old k380 and was probably just worn out. I'm reluctant to give a bad review because I know that these are good, dependable machines and I know what they are capable of and not capable of. That's why I bought one as I am starting my own business. Somehow I just seem to have a bad cable and its costing me with downtime and repairs.

Rated 5 out of 5 by from Easy to operate and it gets the job done! I have used this product twice so far, once to get through a clogged drain between our home and the city’s sewage main drain system, which it was cleared. Then a second time to scrape most of the debris attached to the sewage pipes. Both times it was easy to complete the process without any problems or set backs. The motor works quietly and efficiently, so it was the drum in both forward and rearward motions.

Rated 1 out of 5 by from Bad It's heavy, hard to carry. The bow doesn't change. The belt is coming out of the drum. Is difficult to clean. 50x90 elbows do not turn the bow.

Rated 4 out of 5 by from Overall Good, but Welded Cable End broke after Several Attempt... My family owned a quite large size of Laundromat carrying 200 + of wash & dryer machines. While working on several of hard-cloaked commercial drains, the edge of cable end broke twice. (Another one borrowed from family friend's business. Fortunately, Ridgid sell the Repair Kit, so I bought them. By the way, the machine worked well over all, but Ridgid need to work more on the cable end. That is why I only rated Durability as "Average."

Rated 5 out of 5 by from Saddled Sewer Line: compact, lightweight & easy to use. :) We have a dip in our sewer line about 30 feet from the house that slowly plugs up so being fed up with the mess and hassel of getting a professional in I grabbed this unit from a local store. Watched a couple of YouTube videos and tried it out. Very easy to use and a whole lot better than stopping and adding extra cable (professional has an ancient machine). Weight is very manageable and the unit is nice and compact so it does not take up much room. Two uses will pay for this machine and it is available to me 24/7, which is nice because the sewer usually plugged up on the weekends and I hate waiting for help (no toilet, shower or laundry use available).

Rated 5 out of 5 by from 50% PAID FOR WITH FIRST USE!! As an add-on, our new kitchen is further away from the main drain system than the previous kitchen. The longer distance translated into less drain pipe slope than optimal. It's been, therefore, necessary to invite a plumber to our house about every six months to clear the drain. Although the plumber responded quickly and was effective, each visit cost about $250. Therefore, the economics of buying a RIDGID K-400 were obvious.

Rated 5 out of 5 by from This product has good reviews I purchased the unit because of the good review to have it in case I need to clean out the sewer lines. So I have it- and I hope when the time comes it willserve me well.

Rated 5 out of 5 by from Great results I used this to clear roots from my Leach lines. The three heads were perfect for the task. Within 2 hours, the roots were gone and the water was flowing like a river! Cannot say enough good about the results this product produced.

Rated 3 out of 5 by from Beef it up! Needs to come with the 1/2” line standard! It’s a nice little machine but it’s a little frustrating fooling with the 3/8” line.

Rated 5 out of 5 by from Wonderful Machine Well Built & Worked Like a Charm I bought this because I get an occasional blockage about 30 feet from my clean-out plug. I got the model without the auto feed feature. I put the wheels on and the next day took it out to the clean-out plug. I put on the spade tip and fed it until I hit a blockage. Within a minute it had penetrated the blockage. I then ran it all the way to the street. I backed it out and put on the cutter tip and repeated. This literally took 10 minutes. Amazing. Deploying and pulling it back in was no problem. It feed and retracted by hand just fine and it was very easy to feed. I was amazed at how quickly this thing took care of my problem. No more slow drains. The build seemed very good and solid. Kudos.

Drum keeps hitting frame

The back of the drum keeps hitting the back frame, unless the drum it tilted forward.
