Mi-T-M
Pit Cleaner Operator's Manual
5
The Mi-T-M Pit Cleaning System uses your existing Pressure Washer to operate a high volume Sludge Pump. This
Sludge Pump will move liquids, sludge, and solid debris from the bottom of a pit, through 1 ½” PVC pipe and hose, into
the Sludge Cart where it is deposited into a Filtration Bag. The Filtration Bag may then be disposed of in any manner
compliant with EPA standards.
The Pit Cleaner connects to your Mi-T-M pressure washer in place of its standard gun/lance assembly, and uses the
force of the high pressure water to create a vacuum to remove debris and sludge from the pit. The Pit Cleaner comes
with a #4 nozzle which will work with a variety of pressure washers ranging from 1000-4000 PSI and 2–4 GPM. The Pit
Cleaner has a 1:11 flow ratio; a 3 GPM pressure washer will produce a flow of 33 GPM. The more powerful the pressure
washer, the higher volume of debris is removed from the pit.
NOTE: The actual output volumes will vary with the weight and particle size of the material being removed and the
height and distance that the material is moved. For best results with heavier or larger particles use a pressure
and flow nearer to the high end of the suggested pressure and flow.
The following is a chart showing the relationship of pressure and flow for various nozzles in GPM.
