Ridgid K 30 Auto Clean Drain Machine

This is the light-duty drain-opening machine I have needed for some time, far superior to the one operated by my electric drill. So far I have used it to open only one sink drain, and it has performed perfectly. It helps that I have had some practice in feeding a rotating cable into a drain, so I am unlikely to force it, twist it or break it. The foot-operated on/off switch allows for excellent two-handed control. The one flaw, as many have noted, is that the cable has no markings to show how much has been fed into the drain. (That is why I rate Ease of Use only as "good.") Therefore, before using the machine, I painted every 24 inches of the cable a different color, up to 18 feet. What a great help!
