Massive clog at a local apartment complex.
Hydro Jet in action (see video at right)

A pipe is a pipe, and pipes get clogged, no matter how big. King Mechanical has seen it all. From the kitchen sink to the hundred unit apartment complex, no clog is too big. These pictures are from a clogged sewer that started as a call for a clogged toilet. As you can see, the hydro jet makes easy work of the grease and tree roots. 

Grease and tree roots removed from sewer.
Several inches of grease build up.
