Customer Questions & Answers

is this good for snaking out a toilet bowl to the sewer

Asked by: Anonymous
It is not recommended for this, probably because of possible damage to the bowl. I suppose if you remove the toilet, you could try it.

Is the snake attached to the drum?

I am little concern if keep pressing forward, the snake might come off the drum and get stuck in the pipe.
Asked by: gennzyannd
No it is not attached, according to the documentation.

K45 Auto-Feed Drain Gun is rated 4.9 out of 5 by 20.
Rated 5 out of 5 by from Great tool! Powerful tool. Don't have to touch the snake and get gunk on your hands. Works much faster than the manual snakes. This thing is awesome if you don't mind paying the high price. I'm not a professional but I have several houses that I take care of and I'm thinking this thing is going to be worth it in the long run....

Rated 4 out of 5 by from These work well, but there is a learning curve. The small diameter cables are very easy to flip ... These work well, but there is a learning curve. The small diameter cables are very easy to flip inside the drum, and if you aren't careful you can easily get your hand wrapped around the cable. These smaller cables are easy to kink as well. You want to be cautious when using one. Keep the drill as close to the drain opening as possible so that there is only as much loose and exposed cable as you absolutely have to have. Exposed cable can twist up on itself, damaging the cable; catch on objects like your hand, hair or beard which I know all too well from experience; or wind up hitting fixtures and causing damage. If you hit an object in the line and are not careful the cable will flip in the drum and knot itself up. If this happens you will need to pull the drum out and re-feed the cable in to it. Also, never run a cable machine in reverse. The reverse function is used only to unwind the cable if it gets wrapped up, or attempt and dislodge it if it gets stuck. Running a cable in reverse under strain will damage it, and Ridgid will not warranty a cable damaged in this way. For my money, I usually use a small drum machine inside a home, but I do have these on my trucks. They can work, but can be very problematic to the uninitiated. It takes some time to use these without any issues, and if you ruin a cable you won't be saving yourself any money.

Rated 5 out of 5 by from Little steep but WELL WORTH IT Its expensive for just a little household work but if you feel you need it, its worth it. Especially the auto feed/retrieve, works like a champ and is easy to operate and stops the mess. Its not for the clogged toilet, use the Rigid 6ft toilet auger for that, another great tool, but if its a main line remove the toilet and use the drain gun. I own a couple of rentals and have had all types clogged lines and wish I could have bought this years ago. This is one product that really works like it promoted and does it well....

Rated 5 out of 5 by from Property owner essential Wish I had one long ago. I think about the money I could have saved paying plumbers to do small plugged line jobs. Hope it last a long time.

Rated 5 out of 5 by from Great product! This tool works great. I was able to unclog my tub in minutes. It is powerful. I have used other tools before and none have done the job as well as this one. Worth every cent.
