The original dual cable sectional drain cleaner from Electric Eel (Model C) cleans 3” to 10” diameter lines with up to 200’ of 1 1/4” self-feeding dual cable in 8’ or 10’ sections. This machine spins cable at twice the RPM for maximum cleaning power in 3” to 10” diameter lines. The Model C unit is ideal for tougher blockages such as tree roots and for longer runs in main sewer lines.
