I tried a manual one, can it gets stuck, I think on a lip or something, when I have the plumbers out with their rodding machine, that goes through no problem, it seems that one, swings the cable around to it gets over the lip.
I also tried on you attach to a drill and that was worthless.
Is it worth it do spend $400 for one of the rodding machines?
Is there any technique to using one? I am just worried about forking over the $400 and the have the cable get stuck on the lip again.
The best drain cleaning machine is probably a "jetter". Basically, a jetter is a high pressure washer with a long hose you push into your drain pipe. You connect the jetter to a water supply and the electric pump pumps that water down the jetter's hose. The water comes out the nozzle at the end of the hose at anywhere from 800 to 2100 psi, and cleans the ID of your drain pipe clean as a whistle.
Because of the way the jetter works, you can use the same jetter to clear anything from a 1 1/4 inch drain to a 6 inch drain pipe. The jetter hose is much thinner and more flexible than a metal snake, so it's easier to get into and out of drains. The jetter hose doesn't rust like a steel snake, so there's virtually no chance of having it break or get stuck in the drain pipe.
But, even an inexpensive jetter is gonna cost more than $400, I think.
