Ridgid K-750 AUTOFEED Drum Machine
#8 in Main linesFull review
For plumbers and building crews who clear main lines and roots every week. It is overkill for a homeowner with one stubborn clog.

3.1/5
For contractors and rental fleets clearing roots out of sewer mains. A homeowner with one root problem is better off renting this class of machine.
