In this video from the 2025 Water & Wastewater Equipment, Treatment & Transport (WWETT) Show, Dave Dunbar of General Pipe Cleaners explains why the company’s guide tube is one of the most important safety features on a drain cleaning machine.
“This separates you from the cable,” he says. “If I put this down in the cleanout I’m working on, and I do it effectively, the cable can’t get out of there. No matter what happens . . . We say that you can actually push the functional limits of the machine to its capacity using the guide tube.”
