Hydro-jetting

High-pressure water jetting, also known as hydro-jetting, is a technique of cleaning and unblocking drains. As the name implies, this technique involves the use of high–pressure water in order to clean clogged drains properly and remove the toughest of blockages that might exist in your drains and pipes. High-pressure water jetting is the use of high-speed streams of high-pressure water to cut through almost all solid materials and to clean various surfaces.

In high-pressure water jetting, high-pressure water is forced to pass through the small hole or orifice of the jet nozzle, where the restriction of the small orifice results in a high-pressure water stream.

High-pressure water jetting can be just pure water or water with abrasives, cleaning chemicals or other additives at an operating pressure of between 10,000 to 25,000 psi (70 to 170 MPa) from a system that includes an engine, pump, water storage tank hose, specialized nozzle and other accessories
