For the most precise leak detection, plumbers use video pipe inspection equipment. These are small cameras mounted on long flexible fiber optic cables. Plumbers can insert these in faucets and other plumbing outlets to detect leaks.

The term “rooter service” comes from the problem this service is meant to address: tree root invasions blocking sewer or plumbing lines. While the original design for the rooter machine is no longer used, its conception has led to several effective drain cleaning tools and techniques still in use today.
