High Pressure Jetting

For sewer jetting, a jetting nozzle is attached to the end of a length of high pressure hose with the other end connected to a high pressure water pump. Jetting nozzles have small precision machined orifices or jets to restrict water flow from the jetting pump thus causing high pressure to build within hose.

As the pressurized water is expelled from the nozzle jets it reverts from pressure to velocity (speed) creating thrust that allows the nozzle to pull the jetting hose. With the system pressurized, high pressure jetting hose coiled on a hydraulic powered hose reel (up to 500') is released by the operator who controls the travel speed and distance of the nozzle up the pipe.

Pressurized water expelled from the nozzle jets cleans debris, removes pipe blockages or roots from the inside of the pipe while traveling through the pipe. Optimum cleaning is achieved when the hose is being rewound onto the hydraulic reel.

During this action, water from the nozzle jets effectively forms a curtain or wall of high pressure water that forces (or rakes) the debris downstream. Sewer jetting technology can be applied to clean all size pipe diameters with the appropriate size of high pressure jetting unit.
