Sewer Machine

My best bang for the $$ has been a sectional drain cable machine, I've since just hooked into my drill adaptor and run it like that. but its got stuff unstopped that my little ridgid flex shaft couldn't touch. The flex shaft/chain knockers are great for what they do but dont carry ANY torque to really push their way through the clog.

Get yourself a 5 spool serger by Juki 

I agree with Jason on this.  The flex chain snakes are awesome for portability, light-weight (comparatively), and mostly cost effective (though we all know plumbing tools like this are rarely inexpensive!) I have the M18 chain snake and while it hasn't seen a lit of action yet, the times I HAVE used it, it's gotten the job done.  As you progress and hopefully your business grows, you can't go wrong Spartan or Rigid. Both solid choices, but tend to have a higher price point and a lot heavier depending on the model you purchase.  Best wishes!  Thought about a sewer camera to go along with your drain machine?

Hey, Novaksplumb518,

If you're looking for cost effective and something that can handle main drains, you can find units on sites like Vevor. Other than brands like Vevor you could go for something in the Ridgid lineup. Other options would be a better setup but it all depends what you're interested in doing like main drains or smaller fixture drains. Hope this helps!

Least expensive and most portability are the Chain Knocker Flex Shafts, look at Plumber-Tools website, coming from across the Atlantic in Finland, these tools cannot be beat to unclog your ordinary Grease or Wet-wipe blockages, spend a few extra hundred for the M18 drill foot pedal, to utilize 2 hands to push and pull the Auger, this setup in itself being cordless and lightweight, means rooftop vent access is a breeze and not having to run an extension cord is such a relief. Otherwise, I also have my eyes set on a future Hydro Jetter by General Tools for when the time arrives, small residential jetter thats contained in a sealed Diamond plate box. I think gone are those days of those heavy Ridgid sectional or drum machines, or just for those larger commercial runs.
