microDrain™ Inspection System
adjustments as the drain is being inspected. For in-
stance, white PVC pipe requires less light than black
PVC. Slight adjustments in lighting brightness can be
used to highlight issues discovered during an in-
spection. Always use the least amount of lighting to
maximize picture quality and reduce heat build up.
4. If recording the inspection, follow the instructions in the
specific CCU Operator’s manual.
5. If possible, run water through the system during the in-
spection. This helps to keep the system clean and
makes pushing the pushrod easier. It also helps to ori-
ent the image to the bottom of the pipe. This can be
done by placing a hose down the line or turning on a
fixture/flushing a toilet. The flow can be shut off as
needed for viewing.
6. Grip the pushrod and carefully start to feed it into
the drain to be inspected. It is recommended that
rubber gripper type gloves be used to manipulate
the pushrod. They improve grip and help to keep
hands clean.
Use of the microDrain camera in porcelain
appliances will cause scratching to the surface fin-
ish of the appliances. To avoid scratching a toilet, for
example, use a curved non marking pipe segment to
lead the camera past the porcelain bowl and into the
drain.

When pushing the pushrod in to the line, keep the pushrod
clear of any sharp edges on the inlet that could cut, grab
or damage the pushrod Grasp and push short sections of
pushrod at a time and keep your hands near the inlet to
better control the pushrod and prevent it from folding
over, snapping, cutting the pushrod jacket or other dam-
age. Cutting the pushrod jacket could increase the risk of
electrical shock.
As the pushrod is fed into the line, watch the monitor to
know what is coming. When the lights are set at less
than maximum setting, it may help to occasionally turn the
brightness up to see what is coming further down the
line. Be aware of obstructions (such as crushed pipe) or
excessive hard build up in the line that could prevent re-
trieval of the camera. Do not try to use the camera head
to clear obstructions. The microDrain System is a diag-
nostic tool, not a drain cleaner. Using the camera head to
clear obstructions could damage the camera head or
cause it to be caught in the obstruction, preventing re-
moval

Camera Head To Clear Obstructions
Most of the time a slow steady push through the system
works the best. At changes in direction such as P-traps,
Tee’s, Y’s, elbows, etc., it may be necessary to use a
quick push to “pop” the camera head around the bend.
This is done by pulling the camera head back from the
bend approximately 8" (20 cm) and giving it a quick thrust
through the bend. Be as gentle as possible, and use no
more force than required to do this. Excessive force can
damage the camera head. Do not hammer or snap the
