A hydro jet also called a “hydro jetter” or just a “jetter” is a specialized high-pressure drain cleaning tool that moves through your pipes to break away buildup and flush away residue.

Hydro jetting is a method professional plumbing contractors use to clean clogged or slow sewage lines. It utilizes high-pressure water to remove blockages and build-up. Hydro jetting systems normally run at around 2,000 to 4,000 PSI (pounds per square inch), which is strong enough to cut through tree roots up to a quarter-inch in diameter.
Hydro jetting requires professional experience and the correct equipment, such as a camera system to see inside a problem drain pipe.
