I agree, it can be painful at times in dealing with these jobs. The worst is having to pull a toilet to remove the clog. Whether it is in the basement or on the second floor.
I have a cut in my right finger from Friday morning, Friday evening I was rodding a drain for $205 for 40 minutes which included a 2lb jar of RootX. That finger has been scaring me ever since because it got infected even with rubber gloves on under my metal mitts. I guess transfer is to blame from something. I do turn down some calls but some are so easy that I can't say anything other than you plumbers know what it feels like to hit a clog without much effort. Feels good and hope the next one doesn't beat you down just to earn a buck.
I guess I have a question for plumber1 and MPM in regards to the Ridgid K50. Before I bought my equipment years ago I used to rent numerous machines. I started with the Ridgid K50 and literally hated the fact that I had to touch the cable so much to operate it along with watching where it goes behind me. I agree it packs a punch but you are constantly adding/taking cables off unless your in a garage/basement where you can pull the entire length out. And the mess was horrific if you hit a sludge line where it's all black. You know the clogs I'm talking about.

You spend more time back at the shop cleaning the rolls of cable more than the time at the job.
I used an electric eel about two times, couldn't stand it. No forward force with the machine rolling on the ground; the cable reels out of drain if it hits anything hard.
The only other ones I've used is general drum machines. I hated them because they are reverse rolled cables and no powerfeed. (rentals only)
I have a lift hitch, gets my machine up and down out of the back of my truck
That gets me to the front door but I only run 75 feet of cable with a 2ft leader on the 300. Very rarely do I have to add another 25ft.
I guess my statement is just this; I've ran my 300 many times where all I have to do is pull that lever into forward or reverse and
one hand the cable most times when it turns a direction in the drain or approaches the clog. I sit on a stool the whole time I'm operating it and I never go back to the truck until the drain is clear and I'm bringing the machine back. I'm trying to figure out how handling the cable so much with the Ridgid is better?
How do you use that machine in a $300,000 home on the second floor with back to back toilets using a drop head, dragging up the steps with white carpet and a narrow bathroom? Most times they used a 3" double cross tee which SUCKS.

I reeled in a tv, curtains, and pulled a ruff of carpet up with the Ridgid once all because I wasn't paying attention to what the cable was doing behind me. I'm not speaking from lack of experience; back in the day the
Ridgid K50 was the only thing I could rent. I had to buy a couple cables too due to losing a cable down the drain. I blame that on being green 20 years ago.
