The K-400 lives up to the RIDGID reputation for professional grade tools. Used it to clear a sewer drain from an outside cleanout and it worked just as described in the manual. Instruction DVD was a big help as this is a fairly complicated tool for a DIY homeowner. Wish it came standard with the autofeed option. Only problem is workmanship related: I noticed after using the tool that the cable end was not secured in the drum clamp. Looks like one of the cable clamp screws are cross threaded and the cable either wasn't installed in the clamp or was loose and came out. Other than this minor problem 5 our of 5 stars and after one or two more uses it will have paid for itself!
HD has been my "go to" store for emergency purchases and the last time I purchased a electric drain cleaner was when I purchased house. Recent trunk line clog required something more stout other than hand held electric snake hence a K400 purchase. Clog cleared however the heads provided in kit are of limited use. C-cutter eventually cleared tree root clog and I wish HD would stock a better selection of cutter heads along with 1/2 inch cables. FYI, the drain cleaner rentals at HD are "hit or miss" not to mention ocassional malfunctioning units which is why I purchased new. Cost analysis on purchase indicates a minimum of 2 useages before purchase is completely paid for...not a problem for me since I lend it out to family members. Home Depot Rocks especially with their tool department....I'm like a kid in a candy store each time I walk down the tool aisle!
Pros: good unit for homeowner use
Cons: stock more replacement cables and cutters hd!
I have both rented manual and power drain cleaning equipment to clear the main waste line. I own several Ridgid hand tools,and have had no problems with them. So in my search to purchase and power drain cleaner I went on line to research which brand was preferred. I'm sure the commercial machine that I have rented @ seventy dollars an hour have more power than the K-400,but for the money this machine is a welcome tool for my collection.
Don't get me wrong Rigid has been making high quality industrial tools for decades. I brought home the box and it took 5 min. to assemble it. I started feeding the line into the drain to about 60 feet. Pretty much an uneventful snaking of the pipe. As I was pulling the snake out I saw a shiny, new nut on the floor. The mounting bolt that holds the electric motor to the metal frame fell off. The remaining 3 bolts were only hand tight. Once I tighten the bolts everything looked ok, but I'm unsure if the motor may have moved out of position. Since I was done snaking the pipe I had no way to test it. Quality control needs to be vigilant or these type of events will tarnish Rigids good name, and my faith.
I've had this rigid auger for approximately five years. I have used it to cut through roots in my main sewer line time and time again. like others have said, with a little patience, it will do anything for you. I highly recommend this machine.
Ok for small lines 1 1/2" to 3", but Buy 2 extra foot pedal switches. the one it comes with will be deflated within one use and the replacement you have to buy (not sure why its not under warranty) wont last either and with you in the middle of snaking a line and the machine wont run it makes it difficult. Not home depots fault but rigid has poor customer service
I run the maintenance and construction department for a private college, and must spend my money wisely on both materials and tools. I researched the quality and versatility of many commercial grade drain cleaners and found that I was the most comfortable with the K-400. I came to realize that out in a rural setting, that saving the money of having a plumber come and clean a main drain just 2 times pays for the machine. It has already paid for itself in less than one month. No regrets. No Complaints.
Pros: Reliable, Good Instructions, light enough for one person to lift.
I don't want you to have to go thru what I went thru, hence this review. I spent - not kidding - 10 hours researching online. Amazon, home depot, plumbers forums. I needed to clear my main line of tree roots, feminine products, etc. Many plumbers said I would injure myself, possibly crack my skull. Also, that this product was too small to work on a 4" line and roots. Well, they couldn't be more wrong. I suppose there are always exceptions, but at no time did I fear injury from using this product. I did not follow the manufacturers instructions. I put it right in the 4" line and went to work on the 4" roots. It took 8 passes 75' out with the supplied 3/8" line, but this machine pulled approximately 5 pounds wet of tree roots. I don't like being lied to, and I believe the worst thing you can do many times is listen to free advice. Buy it. You'll be glad you did when it's 20 degrees out and you can't get a plumber to answer the phone, or they answer the phone and you wish they hadn't. Enjoy!
Pros: Reliable, Easy to Install, Good Instructions, No Leaks
We bought this snake to replace a very old one of a similar type which was on its last legs. We live out in the country and get clogs in the sewer line going to the septic tank about once a year. This new Ridgid snake works great and feeds into the drain pipe very smoothly. We used it to clear a clog in the main sewer line when the old snake failed to do it. Used the bulb auger and got the drain flowing well again when the snake was removed. Very valuable to have on hand and not have to wait for or pay the plumber...in a few more uses it will have paid for itself. On the old one we had, the belt was continuously coming off but not on this new one. Looks very well made and the built-in wheels and handle are handy for rolling it to the sewer cleanout outside.
After spending Saturday with a 50 foot spring snake trying to clean out a kitchen/laundry drain line, I took the plunge and got a Ridgid k400. Machine comes with 75' cable, three cleaning tips, gloves, and an instructional CD. I ran the 'pear' tip through the plugged drain in 15 minutes, and it came out full of hair. It was followed by a flat cleaning tip, and drain flows just fine. Note: instructions (inside the box) specifically say that the K400 is not intended to cut roots. Fortunately, roots weren't my problem, just a congealed mass of hair, soap solids, and grease.
First time use the belt came off. Belt keeps coming off in reverse. Most important is that it works for what I need it for but is a bit of a pain due to belt slipping off. All it needs is a bumper to keep the belt from falling off the drum. I will probably make one when the pain of it coming off really bothers me. So - belt issue gives it 3 stars if not for that then for the value it is worth 5 stars. Prige is good and of course Ridgid is my choice of power tools always.
I mainly use this machine for clearing clogs in 1 1/2" and 2" pipes and it does a great job. The machine has held up very well and I have had no issues. I wouldn't use this machine for 3" or 4" lines just because the cable size would be to small especially if there were roots in the line.
Easy to use, light enough to haul around, upstairs and 3rd floor apartments. Works great if you try to snake it from inside the house out. The provided 75ft x 3/8" cable tends to twist a bit when using on the main sewage line. The printed aid (online and from the box) is wrong. This machine can only handle 75ft - 1/2" cable or 100ft - 3/8" cable. It cannot support the 100ft 1/2" cable as advertized after verifying with manufacturer. I would not buy this machine if I knew this info before hand.
I had a stuck drain which had been nagging us for the past 3 months. We have tried everything-small snakes, handheld snakes, and drain chemicals to dissolve the blockage. We decided we needed a drum type snake. I then went to the rental store to rent a drum type snake. I got it home and plugged it in and found out that the motor was burned out. So I brought it back to the rental store and they credited back my credit card. I finally decided that I am going to buy the best and I went to Home Depot and bought the Ridgid K-400. I plugged it in and went to work on my drain. I couldn't figure it out. It wouldn't drain like it should. I tried all the different bits that are supplied and last of all I put the cutting bit. Suddenly all the water disappeared! I was so relieved. We started pulling up fragments of a rag. I don't know how it got down there, but now the drain is clear and it is draining. I also have rentals so that is another reason I decided to buy the machine. I am very happy. All I can say is after you have exhausted all other means, use this machine. It worked great and I would recommend it to anyone who has a serious job to do. Tom in Raleigh, NC.
After paying the pros 3 times over 6 years, I decided it was time to own one. You never know what a tenant is going to put down the drain. This time 10 o'clock at night it was toilet paper, lots of toilet paper. Checked the HD website, 8 AM Sunday morning picked it up, half hour later problem solved. Before this I fought with a 50 ' hand cranked cable without any results. Lots of time wasted, dirty, and frustrating. The time before it was hair and grease. We have a low slope to the septic tank and know we'll have problems for as long as we own the property. The next time I use it, it will have paid for itself. Unless you have clean out, be sure to buy some extra toilet rings. Thanks Rigid
Pros: Reliable, Easy to Install, Good Instructions
With a little time and patience, this thing cuts through roots, which was exactly what I needed! It's quiet and powerful. Build quality is good and sturdy. It says made in the US but not all parts of it are which is a little dissapointing but overall Rigid products has never let me down so far. Lifetime warranty! For the price, they could have included the autofeed. Other than that, I'm a happy customer!
Machine is sturdy and does the job. I chosen to buy instead of renting or calling for service because I have a clog once or twice a year, and when it happens...it is a hassle because MURPHY's always on your side and you are usually in trouble! Machine does a great job removing ROOTS (my main problem) with supplied hardware. You DO HAVE TO be careful when operating, it is very important to read the safety tips before attempting to use it, however there is NO WORRIES in using the machine if you follow instructions and work slowly, as the machine is very well made and has some good safety features.
Pros: Easy to Install, Reliable, Good Instructions, no heavy
I also "took the plunge" and bought this unit about two years ago. My only regret is that I did not buy it sooner. Yes, one or two uses and it is indeed paid for. Not that hard to use at all, especially if you have observed a rooter guy routing out your main line. Follow the instructions, see the video and it's a snap for the intermediate DIYer. And yes, the auto-feed attachment is nice to have, but not essential - I eventually bought one. Product is a Rigid, so rest assured you get a well-built, quality product. Find a place to store it with your important tools. You are going to have it for a long, long time.
I bought this product do to clogged drains to clear roots. I hired professional plumber before to clear my pipes but it was getting pricey. So i picked up one. It does work great on larger pipes and straight shots, Some 90 degrees were difficult to maneuver. You have to go slow but it does get through small roots, i will need to invest in a cutting head. Only complain is they need a 100ft cable, not 75ft
