RIDGID 74978 K9-12 FlexShaft 1/4" x 30' Wall-to-Wall Professional Drain Cleaning Machine, Compact Drain Cleaner for 1-1/4" to 2" Pipes

Chain is an excellent idea, that cleans the inside of the drain pipe!👍

I love how well this tool works! The fact that the shaft spins within its sheathing is amazing!! One word of advice though....take the set screws out of the knocker chain with the provided allen wrench, add blue thread locker and reinstall. I was so excited to clear my first line that I didn't double check that they were tight. All of a sudden, it felt a little funny as I pushed. When it surfaced, the set screws on the closest end of the knocker chain were gone and the chain had balled up. Ended in a trip to the hardware store. Had I not stopped and pulled it out when I did, the chain would have probably been lost down the drain as the remaining set screws were loose as well. Other than that, it's a super design for a DIY homeowner.

Made the clog worse by scraping more grease and dirt from the pipe pushing it towards the clog now a bigger clog . This is good for already clog free pipes that you want to clean . This came with chain knocker that made things worse scraping more crap from the pipe over the clog that’s already there .

Exactly what I ordered. It only comes with single chain setup, Comes in handy for those pesky kitchen sink drain clogs. Specially if you have grease.

After working for years with K43 It's more convenient and you don't have to look for a power source.Suitable for unclogging kitchen and shower drains

Buen producto. Trabaja con eficiencia.Recomiendo para trabajos de plomería.

This will not take the place of a rooter, but once you have the pipe opened up it will clean the pipe walls better than a rooter ever could. I cleaned out a laundry line that was about 25 feet long the first time I used it. I had to fight it to get it in as I was not using water. But once I got to the end of the pipe, I put on a small trickle of water and ran it back and forth every foot pulling it back. After one pass I put my cheap sewer cam all the way through the pipe and It was clean as it could be. It was a better result than I expected on a 60 year old cast iron pipe. It looked like a new pipe. Next time I will use some water on the way in as well as long as it is draining. The 30 foot length is from the tip to the connection inside the drum, so maybe 26' of usable line, which is enough for most residential pipes

I don’t recommend this. It gets stuck and doesn’t turn. Worst buy so far.
