There’s a YouTube channel called Drain Addict where you can find oddly satisfying videos of a plumber cleaning drains. The guy who runs it is from Australia and he never thought his channel would become so popular.
“This channel shows drain cleaning blocked sewer drains using a high-pressure water jet machine,” he says. “The high-pressure water hose that cleans the drain has specific nozzles on the end for cutting out tree roots, grease blockages, and clearing rubble out of drains. It is a disgustingly dirty and smelly job, but someone has to do it, so it may as well be me.”
