3. Components
Familiarize yourself with the main components of your Truper DECA-25 drain cleaner:
- Polypropylene Drum Housing: The main body that stores the 25 ft nylon core cable.
- Handle/Knob: Used to rotate the cable and feed it into the drain.
- Quick-Release Lock: Mechanism to secure or release the cable for extension or retraction.
- Spiral Tip: The working end of the cable designed to break up and retrieve clogs.

4. Setup
- Prepare the Work Area: Clear any items around the drain. Place old towels or a bucket under the drain opening to catch any water or debris that may come out.
- Wear Protective Gear: Always wear heavy-duty gloves and eye protection before beginning.
- Access the Drain: For sinks, you may need to remove the stopper or P-trap to get direct access to the drain pipe. For toilets, insert the auger directly into the bowl.
5. Operating Instructions
Follow these steps to effectively clear a clogged drain:
- Unroll the Cable: Loosen the quick-release lock and pull out a few feet of the drain cleaner cable from the drum housing.
- Insert into Drain: Carefully insert the spiral tip of the cable into the drain opening. Push it down until it meets resistance, indicating the clog.
- Engage the Lock: Once the tip reaches the clog, tighten the quick-release lock to secure the cable in place, allowing you to apply torque.
- Rotate and Push: Turn the handle clockwise while simultaneously pushing the cable further into the drain. This action helps the spiral tip to bore through or hook onto the clog.
- Advance the Cable: If the cable stops advancing, loosen the quick-release lock, pull out more cable, re-tighten the lock, and repeat the rotation and pushing motion. Continue this process until the clog is broken up or retrieved.
- Clear the Clog: Once you feel the resistance lessen, indicating the clog is broken, slowly pull the auger out of the drain. If you've hooked onto the clog, carefully retrieve it.
- Test the Drain: Run hot water down the drain for several minutes to flush away any remaining debris. If the drain is still slow, repeat the process.
- Clean the Auger: After use, clean the cable thoroughly with water and a disinfectant. Wipe it dry to prevent rust before retracting it back into the drum housing.

6. Maintenance
- Cleaning: After each use, thoroughly clean the entire length of the cable and the spiral tip. Use a stiff brush and warm, soapy water to remove all debris and residue.
- Drying: Ensure the cable is completely dry before retracting it into the drum housing. This prevents rust and corrosion, extending the life of the tool.
- Lubrication: Periodically apply a light coat of rust-inhibiting oil to the cable to maintain its flexibility and prevent corrosion.
- Storage: Store the drain cleaner in a dry place, away from extreme temperatures and direct sunlight.
- Inspection: Regularly inspect the cable for kinks, fraying, or damage. Replace the unit if the cable is severely damaged, as it could break during use.
7. Troubleshooting
- Cable will not advance:
- Ensure the quick-release lock is properly tightened when pushing and rotating.
- The clog may be very dense. Apply more pressure while rotating, or try pulling back slightly and re-advancing.
- The cable might be hitting a bend in the pipe. Gently rotate and push to navigate the bend.
- Clog not clearing:
- Ensure the cable has reached the clog. You may need to extend more cable.
- Increase rotation and pushing force.
- The clog might be too large or too far for this tool. Consider professional assistance for severe blockages.
- Cable gets stuck:
- Do not force the cable. Gently rotate it counter-clockwise while pulling back to free it.
- If it's severely stuck, try to rotate it clockwise again to break up whatever it's caught on, then pull back.
