The Jetting Process
Sewer jetting (or hydro-jetting) uses a combination of water
pressure (psi) and flow (gpm) through a hose and nozzle to
flush debris out of drains 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.
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 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.
Components of hydro jetters: Water pump, motor, 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 water
supply buffer.

Instructions and Precautions
Pumps
• Remove “shipping” plug on top side of pumps and
replace with vented plug. This is very important for
the proper operation of the pumps.
• Do not store or run the pumps on its side or at a
sharp angle, since oil can run out of the vent plug.
Environment
• Use caution in confined, wet areas. Drain cleaning
professionals often work directly through non-trapped
openings into sewers — make sure that there is adequate
ventilation into the work area.
• Neutralize or remove corrosive drain cleaners from drain
before starting.
• Do not operate machine in areas where combustible gases,
liquids or dust are present. Fire or explosion may occur.
Keep bystanders or unauthorized persons away
Insist they keep a safe distance before operating
high pressure equipment.
• Never hold on to nozzle or point it at anyone with machine
turned on. High pressure water streams can cause serious
bodily harm.
Always insert hose at least 3-4 feet into pipe opening and
hold onto hose before turning the machine on.
Shut the machine down:
• When changing nozzles, hose or reels.
• Before disconnecting water supply. Running a water pump
“dry” will seriously damage the water pump.
• If it will be unattended.
• If machine fails to run properly.
Common Sense
• Don’t operate equipment while smoking, under the
influence of drugs, alcohol or if taking medication that alters
alertness.
• Wear goggles or a face shield to product your eyes, protec-
tive gloves, rubber sole boots, and other
protective clothing as required.
• Keep all labels, decals, warnings, cautions, and instructions
with machine. For new decals or labels contact Mytana.
• NEVER run flammable liquids or toxic chemicals (such as
insecticide or weed killer), acids or hard caustics (such as lye)
through the pump. Only water!
