Hydro jetting is a method to remove dirt, build up and blockages on pipes using pressurized water through a jet nozzle.
Hydro jetting systems use pressures starting as low as 4,000 pounds per square inch to as high as 60,000 psi, depending on the severity of the blockage.
The most common nozzles used are flat jet nozzles, point jet nozzles and rotating nozzles.
