How do I use the VIPER flush camera to inspect sewers?
Steerable VIPER Jetting Cameras – "Made in Germany"
For efficient pipe and sewer cleaning, we now offer three different models of the steerable VIPER jetting camera system: a light version, a compact version, and a long-range model with an extended cable. To make sure your VIPER fits your jobsite perfectly, we offer different setups – from a compact portable version to a high-power model with extra long range (see our blog post: New, steerable VIPER Video Nozzle | MOWOTAS).
The key differences between the models are the hose lengths and how the units are transported – either on a compact cart, with or without an automatic hose reel, or as a portable carry unit.
All camera systems use the same camera head and flushing system. An optional high-performance steering nozzle with interchangeable rotating jets is also available.
Got a VIPER jetting camera from us and ready to get to work? Let’s go!
Operation
- Before you begin, push the camera at least 1 meter into the pipe and move out of the danger zone – high-pressure water and debris can be hazardous.
- To protect the hybrid hose, use a manhole roller or a protective sleeve.
- Before starting the jetter, make sure the bypass valve works correctly to avoid damage.
- Hold the hybrid hose firmly and open the ball valve on the hose reel.
- Start the high-pressure unit. You’ll see the pressure build on the control unit and feel the pulling force increase.
Cleaning & Inspection
- Start feeding the hose into the pipe. Rotate the hose so that the camera rides at the top (the pipe crown) – this helps keep the lens clean.
- Use the angle display on the monitor to keep the camera upright.
- Stop if you see sharp debris like glass that might damage the camera or block its path.
- If the hose doesn’t pull back smoothly – stop immediately. Keep checking this during use.
- For even better cleaning, especially with the 3-part nozzle set (optional), use the rotating jets to remove more buildup.
Navigating Obstacles
- If you come across intruding connections or obstacles, think ahead: can the camera come back easily once it’s past? If you’re unsure – stop.
- Turn the hybrid hose slowly and feed it gently to steer around the problem area.
Steering Through Bends
- To get through tight bends, rotate the hybrid hose to bring the bend's opening to the 12 o’clock position.
- Then feed the hose – the steering nozzle will help guide the camera head around the corner.
Branch Lines
- When you reach a branch, rotate the hose until the new pipe appears at 12 o’clock on the screen.
- Feed the hose, and the camera will enter the new line. This also works when entering property connections from the mainline.
- To measure branch lengths, reset counter #2 to zero.
Pulling Back & Cleaning
- Reel the hose back in using the manual crank or electric drum (optional).
- Check the pipe condition. If needed, re-clean by pulling back more slowly.
- For a spotless result, use the optional flex segment with rotating nozzles.
Pulling Back Through Tight Bends
- If you get stuck while pulling back, try rotating the hose as you pull.
- If it still won’t come back, push forward about a meter, turn off the water, and try quick pulls to free the camera.
- Never yank too hard – this causes wear and may damage the hose, steering nozzle, or camera.
More Pulling Power & Long-Distance Use
- Increase water pressure for more pulling force.
- Use the shortest possible connection hose between the jetter and the VIPER system.
- For max power, make sure all nozzles are clean and properly installed.
Spotless Cleaning with Rotating Nozzles
- For best results, use the optional rotating nozzle head (shown below).
- Like the standard nozzle, the ceramic inserts can be replaced. It lifts during operation and works at the pipe crown or any position.
- Due to its length, 90° bends can only be passed in pipes larger than DN 125.

Using Recycled Water
The VIPER system can run on recycled water too. Be aware: abrasive particles in the water cause more wear on all parts that come into contact with water. If using recycled water, disable the front jet nozzle.

We hope these instructions help you get the most out of your VIPER HD jetting camera.
