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.

Lowering the LED brightness setting to minimum

activates the built-in Sonde. In models which do not

have a Sonde, the power usually directed to the

Sonde will be output to the LEDs instead, and make

them switch to high brightness from their lowest set-

ting. This behavior is normal.

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
