High Pressure Water Jetting
High pressure water jetting is the utilization of high pressure water combined with sufficient water flow to remove
debris in drain/sewer pipes. High pressure water alone cannot do the job. You need proper flow to wash the debris
downsstream where it can be collected and removed. High pressure water jetting can also be used to remove debris
on surfaces.
A high pressure water jet consists of a pump, a motor or engine, a hose reel, a given length of hose and a
various assortment of nozzles.
A pipe is cleaned with a high pressure water jet by directing water pressure and flow through a nozzle.
Controlled water pressure and flow propels a water jet through the sewer pipe allowing it to remove and wash
away the obstruction. (See Fig. 3.)
Ideally, a sewer pipe is cleaned from the lower end of the pipe and the hose propels itself to the higher end of
the pipe. By slowly withdrawing the jet hose, the water pressure and flow cleans the line most effectively.
When it is impossible to clean from the lower end of the pipe, the pipe must be water jetted several times to
remove all the debris. A skilled operator can effectively clean a drain/sewer regardless of the obstacles in his
way.
How A Jet Works
