Plumber on the Roof: Your Neighborhood Plumber Clears a Clog From Above

The view starts from the roof, looking down at a SwiftPro van parked on a paver driveway. On the asphalt shingles, two techs set up a drain cleaning machine, one in a black long-sleeve shirt and gloves running it, the other, an older tech in glasses, keeping an eye on the line.

They feed the cable down the plumbing vent stack. That pipe lets air into your drain system so water flows freely, and from the roof it gives a straight shot down into the main drain when there's no handier cleanout inside.
