Operating Tips
• Tight bends and certain blockages are often more easily
negotiated by rotating or twisting the jetter hose at drain
opening. Once you are through that area, pull back and pass
through several times to ensure cleaning.
• Once you have opened any blockage(s), pull hose back very
slowly to provide maximum cleaning to wall of pipe.
• Use pulsation only if needed to advance nozzle and hose.
• When operating from the high end to low end (most
common) shut off the water flow ball valve on the reel
occasionally. This will allow debris to get ahead of the nozzle
and flush it down the pipe.
• Warm water is effective in cleaning grease and ice blockages.
A cold-hot mix from the tap is adequate, but do not exceed
140° Fahrenheit. Hotter water can damage seals in your
pump. If you need hot water, use our HotBox water heater.
Anti Freeze Procedure
If you know there will be a period of 2-3 days when the
jetter will be idle OR if the jetter is stored in potentially freezing
weather, make sure to run antifreeze into pump and hose as
part of your shut down procedure.
Insert a short length of garden hose into a gallon of antifreeze.
Turn on the pump and run until you see antifreeze coming out
of the nozzle end of the hose.
At next use of jetter, you can recover most of that antifreeze
when you hook up to your water source. Antifreeze can be
used multiple times. However if it gets too diluted (more than
50% water) or if there is any discoloration, discard and replace
with new. We recommend using RV antifreeze.
Care and Maintenance
Regular inspection and maintenance are key to preventing
breakdowns and prolonging the life of the equipment.
Keep machine clean and dry to maximize performance and
longevity. Keep antifreeze in hose and pump in freezing temps
or if idle for more than 2-3 days, see procedure at left.
Never let pump run dry! Pump cavitation can occur in only
a few seconds of low water supply. Ensure adequate source
supply before operating.
Avoid running anything abrasive through pump
which will damage pump components, resulting in total
malfunction or, minimally, loss of pressure capability.
Do not use pulse valve more than necessary.
Never run pump if there is ice in pump or outlet hose.
Keep jetter hose away from sharp edges and muffler
• The hot muffler can damage the coating on the hose making
it prone to bursting.
• Sharp edges can scrape, slice and generally damage hose
quickly. While hose is easily replaced, it pays to take care by
buffering sharp edges with rags, tape, cardboard, etc. Or use
a TigerTail™ guide, available at MyTana.com.
