Using a Drum Machine

Congratulations! You're reading this because you're ready to take on the wonderful world of drain cleaning. Let's get into the basics of running a VALOR Drum Machine. The VALOR Machine is ideal for 1-1/4” to 4” drain lines up to 75'.

  • Prep the Area
    • Ensure the area around the drain is clear from any obstructions. Lay down a mat or towel to place your machine on, and make sure that the surface is flat and stable. When you've done that, plug the machine into an outlet.
  • Send the cable down the drain
    • Pull the cable out of the drum by hand and slowly begin its descent into the drain.
  • Turn on the machine
    • MAKE SURE THE MACHINE IS IN FORWARD
      • Never place the machine in reverse
    • Turn on the power switch and place your foot on the foot pedal to begin the action. Let the machine do its job and do not force the cable, as this could lead to damage to the cable.
  • Clearing blockage
    • When you feel resistance, you have found the blockage. Stop feeding the cable and let the cable spin in place to break it down.
    • You may need to pull back the cable slightly and re-feed it to make sure the blockage has been properly cleared.
  • Pulling back the cable
    • When you are satisfied with clearing the blockage, retract the cable manually back into the drum. We recommend holding a towel around the cable as you retract it to clear your cable of debris.
  • Clean up
    • Wipe down the area with a disinfectant and clear any gunk and debris from the area. Be sure to wash your drum as well.

And that's it! Using a drum machine is a simple task but will take time to master. Using the VALOR Series line of sewer machines will make your drain cleaning business a breeze.

The Different Types of Drain Cables and Their Uses

Drain cables come in various types, each suited for specific pipe sizes, clog types, and job requirements. Understanding the differences can help you choose the right tool for the task.

  • Inner Core Cables:These cables have a tightly wound inner wire for the perfect balance of strength and flexibility. They're ideal for tough jobs and long distances, commonly used in residential and commercial plumbing.
  • Hollow Core Cables: More flexible and lightweight, these cables are suitable for lighter clogs. They are easier to maneuver through smaller pipes and tight bends.
  • Sectional Cables: These cables come in short sections that are connected as needed, giving flexibility in length. They're used for working with exactly what is needed in terms of cable length and weight.
  • Cable Heads and Attachments: There are also variations in cable ends, such as spearheads, spade cutters, and coil heads—each designed to tackle different clog types like grease, roots, or solid debris.

Knowing which cable to use is key to avoiding damage and getting the job done efficiently.

How to Choose the Right Drain Cable for Different Pipe Sizes

Choosing the right drain cable for your pipe diameter is essential for both safety and effectiveness. Here's a general guide:

  • 1-1/2” to 2” Pipes (e.g., sinks, bathtubs): Use a 1/4” or 5/16” cable. These smaller cables are flexible enough to navigate tight bends.
  • 2” to 3” Pipes (e.g., showers, laundry drains): A 3/8” or 13/32” cable works well, providing more durability while maintaining flexibility.
  • 3” to 4” Pipes (e.g., toilets, floor drains): Opt for a 1/2”, 5/8”, or 3/4" cable. These thicker cables can tackle tougher blockages and travel longer distances.
  • 4” to 6” Main Sewer Lines: Use a 3/4” or sectional cable. These are designed for the most demanding jobs, often paired with power machines.

Remember, using a cable that's too large can damage the pipe or fixture, while one that’s too small might not clear the clog effectively. Always match the cable size to both the pipe and the clog type.

How to Maintain and Store Your Drain Cables

Proper maintenance of your drain cables extends their life and ensures they work effectively when you need them most. Follow these tips:

  • Clean After Use: Rinse off debris and grime immediately after use.
  • Lubricate Regularly: Apply a light coat of Drain Cable Defense by DCD or lubricant to prevent corrosion, especially before long-term storage.
  • Inspect for Damage: Check for kinks, frayed wires, or bent tips before and after each use. Replace damaged cables to avoid further problems.
  • Store Properly: Hang coiled cables or store them in a drum or case. Keep them in a dry area away from moisture and chemicals.

Routine care will save you money on replacements and prevent frustrating failures during jobs.

The Most Common Mistakes When Using a Drain Cable

Even the most seasoned plumbers will run into unavoidable errors. You're always going into the drain line blind and hoping for the best. Here are a few reminders before you start a job:

  • Using the Wrong Cable Size: A cable that's too large may damage small pipes, while a cable that's too small may render itself useless.
  • Skipping Safety Gear: Always wear gloves and eye protection. We recommend wearing Ugly Gloves to wear as you guide your cables to prevent your hand or fingers from getting caught on a cable. Cables can snap or spray debris during use - and you don't want to get any mystery drain juice on your face!
  • Forcing the Cable: If the cable meets resistance, don't force it. Back it out slightly, rotate, and try again to avoid damaging the pipe or the tool. As much as we would love to sell you another cable if your cable breaks, we would rather see you get as much mileage as possible from each cable!
  • Not Securing the Machine: Ensure the unit is on a stable surface, lay down a mat or towel to protect the floor. A moving machine can cause injuries or misfeed the cable.
  • Neglecting Maintenance: Using a rusty or kinked cable reduces effectiveness and increases the risk of breakage. Grease zerks are there for a reason - show them some love with a grease gun every so often.

By avoiding these pitfalls, you can use your drain cable more safely and efficiently, whether you're an apprentice or a seasoned pro!
