Drain Cleaning Vs Drain Clearing - Which Do You Need?

Clogged drains are a widespread problem in both residential and commercial settings. Grease, hair, soap residue, food leftovers, and even tree roots can build up over time and restrict water flow. When the water slows down or stops completely, you have two options: drain clearing or drain cleaning.

Although the names are often used interchangeably, they do not mean the same thing. Drain clearing focuses on removing the immediate clog, whereas drain cleaning addresses the accumulation inside the pipes, thereby preventing future blockages.

In this article, we'll discuss the difference between clogged drain clearing and drain cleaning, when each method is required, and how taking the appropriate approach can help protect your plumbing system in the long run.

What Is Drain Cleaning?

Drain cleaning is a more complete process than simply removing a clog. Instead, it focuses on cleaning the pipe walls and sewer lines to restore full flow capacity and decrease the chances of future blockages.

Professional drain cleaning techniques include the following

  • DrainJet Flushers – with significant flow especially with hot water can flush debris, soap, grease and residue.
  • Hydro Jetting – It is the process of breaking down oil, soap, roots, and mineral deposits within a pipe using high-pressure water streams.
  • High-Pressure Flushing - Clears buildup and debris without the need for harsh chemical drain cleaners.

Drain cleaning is frequently required when blockages occur repeatedly, many drains stop working at the same time, or foul odors and gurgling noises indicate a deeper problem in the sewer line.

What Is Drain Clearing?

Drain clearing is the process of removing a blockage and allowing water to flow freely again. It is considered a quick fix since it focuses on the blockage directly rather than the buildup around the pipe walls.

Common drain cleaning techniques include:

  • Plungers - Useful for clearing minor clogs in sinks and toilets.
  • Drain Snakes - Flexible steel wires that reach deep into pipes to break up or remove clogs.
  • DrainJet Flushers- Use water flow and pressure to clear blockages
  • Augers - Heavier-duty snakes, generally motorized, that are meant for larger drains and tougher blockages.

Drain cleaning is usually sufficient for a one-time clog caused by food leftovers, hair, or other material. However, because it does not remove residue or accumulation on the pipe walls, the problem may reoccur if the root cause is not addressed.

Both methods improve drainage, although they serve different functions. The table below outlines the primary differences between drain cleaning and drain clearing, allowing you to decide which is best for your case.

How to Know Which You Need?

Determining whether you need clogged drain clearing or full sewer drain cleaning depends on the signs your plumbing system is showing. Use the checklist below to help you decide on the best method.

You probably need drain clearing if:

  • It's a one-time blockage in a sink, shower, or toilet.
  • The problem is limited to one drain.
  • Water responds to plunging and snaking.
  • There are no lingering odors or unusual sounds.
  • Tip: Use inflatable or mechanical pipe plugs to isolate the drain and check for blockages before attempting further clearing.

You likely need drain cleaning if:

  • Despite repeated attempts to clear them, clogs keep coming back.
  • Multiple drains are slow or clogged at the same time.
  • Your drains smell foul.
  • Signs of a sewer backup include standing water, gurgling toilets, and wet spots around your septic system.
  • Tip: Consider Petersen’s DrainJet® drain flushers for preventive sewer drain cleaning to remove buildup and help prevent future clogs.

If you're unsure, it's better to call a professional for sewer drain cleaning, especially if repeated signs hint to a larger problem in your plumbing system.

Preventing Future Drain Problems

To keep your drains moving smoothly, follow these basic preventive measures:

  • Avoid pouring grease or oil down the drain. These chemical substances solidify, contributing to buildup over time. Or regularly use hot water with the DrainJet® clear grease and soap. 
  • Use strainers or drain guards to trap hair, food particles, and other waste before they enter your pipes.
  • Schedule professional sewer drain cleaning every 18–24 months, especially for heavy-use households, to maintain optimal flow and prevent recurring clogs.
  • Regular drain cleaning and maintenance not only prevent blockages but also help extend the life of your plumbing system.

Final Thoughts

To summarize, drain clearing is a quick, temporary repair for single clogs, but drain cleaning is a comprehensive, long-term solution that removes buildup and maintains your pipes healthy.
If you're not sure which option is ideal for your situation, especially if many drains are damaged or sewer line concerns are suspected, consult a professional.
