How Do You Use a Snake for Plumbing? (Step-by-Step Guide)

Got a slow-draining sink or a completely blocked toilet? You’re not alone—clogged drains are among the top 5 most common household plumbing issues in the U.S., according to the American Society of Home Inspectors. If plunging didn’t work, it’s time to reach for a plumbing snake. But how do you use a snake for plumbing without making things worse? Don’t worry—we’ll walk you through it safely, effectively, and without calling a pro (unless absolutely necessary).

What Is a Plumbing Snake?

A plumbing snake (also called a drain auger) is a long, flexible metal coil designed to break up or retrieve clogs deep inside pipes. It works by physically pushing through or hooking debris like hair, grease, or food waste that your plunger can’t reach.

There are two main types:

• Hand-crank augers (ideal for sinks, showers, and tubs)
• Toilet augers (specially designed with a protective sleeve to avoid scratching porcelain)

For serious blockages in main sewer lines, professionals use electric drain snakes, but for 90% of household clogs, a manual snake does the job just fine.

💡 Did You Know? The average U.S. household spends $250–$500 on emergency plumbing calls—many of which could’ve been avoided with a $20 plumbing snake.

When Should You Use a Plumbing Snake?

Use a snake when:
✅ Water drains slower than usual
✅ Plunging fails after 3–5 attempts
✅ You hear gurgling sounds from drains
✅ Multiple fixtures are clogged (may indicate a main line issue—proceed with caution)

Do NOT use a snake if:
❌ You recently used chemical drain cleaners (risk of toxic fumes or pipe damage)
❌ You suspect tree roots or collapsed pipes (requires professional inspection)

Step-by-Step: How to Use a Snake for Plumbing

Follow these steps carefully to avoid damaging pipes or worsening the clog:

1. Choose the Right Snake

• For sinks/tubs: Use a 15–25 ft hand auger with a ¼” to ½” diameter cable.
• For toilets: Use a closet auger (toilet snake) with a curved tip and protective rubber sleeve.

2. Prepare the Area

• Place towels around the drain to catch spills.
• Wear rubber gloves—clogs can harbor bacteria.
• Remove the drain cover or pop-up stopper if present.

3. Insert the Snake

• Feed the cable tip into the drain by hand until you feel resistance (usually 12–24 inches in).
• Never force it—let the auger’s natural flexibility navigate bends.

4. Crank and Advance

• Slowly turn the handle clockwise while gently pushing forward.
• When you hit the clog, you’ll feel increased resistance.
• Continue cranking for 10–15 seconds to either:
  • Break up the clog
  • Hook and retrieve it (common with hair clogs)

5. Retract and Clean

• Pull the snake out slowly. Wipe the cable with an old rag after every few inches.
• Rinse the snake thoroughly with warm water and mild soap.

6. Test the Drain

• Run 2–3 gallons of hot water (not boiling—especially on PVC pipes!) to flush residue.
• If water drains freely within 10–15 seconds, you’re done!

🔧 Pro Tip: After clearing the clog, pour ½ cup baking soda + 1 cup vinegar, wait 15 minutes, then flush with hot water. This helps prevent future buildup.

Hand Snake vs. Electric Snake: Which Should You Use?

For most homeowners, a hand snake is sufficient. Save the electric version for recurring main-line issues.

Common Mistakes to Avoid

• Using excessive force: Can scratch pipes or push clogs deeper.
• Ignoring pipe material: Older homes may have cast iron or galvanized steel—be gentler.
• Skipping safety gear: Always wear gloves and eye protection.
• Using a toilet auger on a sink: The design differs—using the wrong type reduces effectiveness.

FAQ Section

Q: Can I use a plumbing snake on a garbage disposal?

A: No. Never insert a snake into a garbage disposal—it can damage the blades or motor. Instead, use a disposal wrench (usually included) to manually rotate the blades, or call a professional.

Q: How far can a hand snake reach?

A: Most handheld augers reach 15–25 feet, enough for branch lines. Main sewer lines (30+ ft) usually require a professional-grade electric snake.

Q: Why did my drain clog return after snaking?

A: The clog may have been only partially cleared, or there’s a deeper issue like pipe corrosion, grease buildup, or tree roots. If it recurs within a week, consider a camera inspection.

Q: Can a snake damage PVC pipes?

A: Yes—if used aggressively. Always advance the snake slowly and crank gently. PVC is durable but can crack under sudden pressure.

Q: Should I snake before or after using a plunger?

A: Always try plunging first. It’s non-invasive and works for many surface-level clogs. If plunging fails after 5 solid attempts, then snake.

Q: How often should I snake my drains preventively?

A: Not recommended. Snaking is a corrective tool, not preventive. Instead, use monthly maintenance with baking soda and vinegar, and install drain strainers.

Conclusion

Now you know exactly how to use a snake for plumbing—safely, effectively, and without panic. Whether it’s a hair-clogged shower or a stubborn kitchen sink, a $20 auger can save you hundreds in plumber fees and hours of frustration.
