The Jetting Process
Water Jetting—also know as sewer jetting or hydro-jetting—uses a combination of water pressure (psi)
and water flow (gpm) through a hose and nozzle to flush debris out of drain and/or sewer lines.
Water jetting is used to penetrate and wash out clogs or ice, potential blockages or to simply clean the
walls of drains and sewer lines to prevent future blockages.
u
Sewer jetting differs from normal pressure washing:
• Sewer jet nozzles direct the flow of water back toward the operator at a 20 to 45 degree angle. This backward
stream propels the sewer nozzle and accompanying hose forward into the sewer line and also cleans the walls
of the pipe.
• Jetting pumps deliver more flow and controlled pressure to clear tough blockages.
• Water pumps on sewer jetting equipment are modified to allow pulsation of water through the hose to the
nozzle. This pulsation creates a vibration or “wiggle” in the jetting hose that allows the hose to move through
a drain or sewer line with little resistance. Pulsating also reduces pressure and/or flow of the water, so most
pumps are equipped to turn pulsation on and off at will.
u
Components of water jet machines: Water pump; hose reel; various sub-components that protect the pump
and the operator; various nozzles for various cleaning applications and situations. Larger jetters use a water
storage tank for additional water supply.
