Snaking a Drain: When to Use It and How to Do It

Dealing with a slow or clogged drain? Snaking a drain is one of the most effective DIY solutions for clearing blockages before they turn into problems. Whether you have hair in the shower or a stubborn clog in your toilet, knowing how to use a drain snake can save you time and money. 

What Is Snaking a Drain?

Snaking a drain is the process of using a flexible, coiled tool (called a drain snake or plumber’s snake) to dislodge or break apart clogs inside your pipes. 

How does snaking a drain work? The tool twists through bends and blockages to pull out or push debris to restore water flow. It relies on mechanical force and flexibility to reach clogs that plungers can’t.

When Should You Use a Drain Snake?

When you’ve tried some of the other lesser-known ways to unclog a drain, and nothing is working, a drain snake should be your next step. In particular, you can use a drain snake when:

• Water is draining slowly or not at all
• You suspect a clog within the first few feet of the drain
• You want to avoid harsh chemical cleaners
• The clog is due to hair, soap scum, or debris and not a broken pipe

If multiple drains are backed up or you hear gurgling in fixtures, the issue might be in the main line. Snaking the main drain pipe may be necessary.

How to Use a Drain Snake: Step-by-Step Guide

Step 1: Gather Your Tools

You’ll need:

• A hand-crank or motorized drain snake (or a toilet auger if you’re snaking a toilet drain)
• Rubber gloves
• A bucket or towels
• Safety goggles (optional but helpful)

Step 2: Insert the Snake Into the Drain

Slowly feed the snake cable into the drain opening. You want the coil to glide in naturally. For sink and tub drains, remove the stopper or drain cover first.

Step 3: Turn the Handle to Break Through the Clog

As you feel resistance, crank the handle clockwise. The snake tip may grab the clog or break it apart. If you feel the snake bind or loop, pull back slightly and adjust your angle.

Step 4: Retrieve the Snake and Debris

Pull the snake out slowly. Have a bucket nearby to catch any debris. Wipe the coil as you go, and dispose of any gunk safely.

Step 5: Test the Drain

Run hot water to make sure the blockage is cleared. If the water still drains slowly, try snaking again or check for deeper clogs.

Snaking Specific Drains: What to Know

Here are a few more specific tips based on the area you’re trying to unclog.

Snaking a Sink Drain Pipe

• Place a bucket under the P-trap in case of leaks
• Feed the snake directly into the drain or remove the P-trap for better access
• Expect grease or soap buildup to cause resistance

Snaking a Bathtub Drain

• Remove the overflow plate to get direct access to the drainpipe
• Feed the snake downward into the main drain, not the overflow

Snaking a Shower Drain

• Remove the strainer cover and clean out visible debris
• Insert the snake carefully to avoid scratching the shower base
• Expect to find a clog within the first few feet

Snaking a Toilet Drain

• Use a toilet auger, not a regular snake,  to navigate porcelain curves
• Insert the auger into the bowl and turn the handle to push through the trap
• Flush the toilet to test if the clog has cleared

Toilet Auger vs. Snake

A toilet auger is a shorter, rigid tool with a protective plastic sleeve. It’s specifically designed specifically for use in toilets.

Drain snakes, on the other hand, are longer and more flexible. This makes them better for sinks, tubs, and shower drains.

Snaking the Main Drain Pipe

• Access the cleanout (usually in the basement or outside)
• Use a heavy-duty or motorized snake
• Be prepared for larger amounts of waste and pressure buildup

When to DIY vs. Call a Plumber

If you have plumbing experience and the problem isn’t big, you can likely handle it on your own. In particular, DIY is fine if:

• The clog is localized to one fixture
• You’re comfortable using a hand snake
• You can access the drain without removing walls or fixtures

However, you should definitely call a plumber if:

• You’ve tried snaking, and the clog returns
• You suspect the clog is in the sewer line
• Multiple drains are backing up
• You notice signs of pipe damage or foul odors

FAQs

Can snaking a drain damage pipes?

It’s rare but possible. Using too much force or the wrong type of snake (especially in old or fragile pipes) can cause damage. Always go slowly and use the right tool for each job.

Can a drain snake make a clog worse?

Yes, if used incorrectly. Pushing the snake too far or at the wrong angle can compact the clog or cause it to shift deeper into the system, making removal harder.

How do you use a drain snake correctly?

Insert the snake slowly, crank gently when resistance is felt, and never force it. Pull out debris carefully and run water to ensure the pipe is fully clear.

How do you get a snake past the P-trap?

For minor clogs, feed the snake through the drain and guide it around the curve. If resistance is too high, remove the P-trap and insert the snake directly into the wall drain.
