To snake a drain, feed a flexible cable (plumbing auger) into the drain opening, rotate it when you feel resistance to break up or grab the blockage, then retract it slowly. This works well for minor, localized clogs in sinks and showers. For recurring backups, multiple slow drains, sewage smells, or deep clogs, call a licensed plumber.
A clogged drain always seems to happen at the worst possible time—right before guests arrive, first thing in the morning, or in the middle of a busy workday. We get calls like this every day at MD Sewer & Plumbing. And the first question homeowners usually ask is: “Can I snake this myself, or do I need a plumber?”
The honest answer is: it depends. A drain snake can absolutely solve certain problems. But used on the wrong clog, in the wrong situation, or with the wrong technique, it can also push a blockage deeper, scratch older pipes, or leave you with the same problem a week later.

We have been helping Maryland homeowners clear drains and diagnose sewer issues for more than 35 years. This guide explains how snaking a drain works, when a manual snake is a reasonable first step, and—just as importantly—when the problem calls for professional equipment and a trained eye.
What Does It Mean to Snake a Drain?
Snaking a drain means using a flexible metal cable—called a drain snake, plumbing auger, or plumber’s snake—to physically reach and dislodge a blockage inside a pipe. The cable is designed to navigate the bends and curves of your plumbing without getting stuck.
When the cable reaches resistance, you rotate a handle or crank to engage the clog. Depending on the obstruction, the auger head may bore into it, break it into smaller pieces, or hook the debris so it can be pulled back out through the drain opening. Once the blockage is cleared or retrieved, the cable is slowly retracted and the drain is tested.
We use drain snakes and professional augers because they give us a mechanical way to address blockages without relying solely on liquid drain cleaners can corrode older pipes and often only burn a small hole through a clog rather than fully clearing it.
A plunger is generally worth trying first for a minor, localized clog. A snake becomes the right next step when plunging hasn’t worked.
For a broader introduction to how plumbing augers work, the team at Family Handyman has a helpful overview.

When Should You Use a Drain Snake?
A snake may be appropriate for localized, minor clogs—particularly after a plunger has failed. Here are the most common situations we see:
A Sink That Is Draining Slowly
Hair, soap buildup, grease, and food debris are frequent culprits in sink drains. A small manual drain snake with a cable around 1/4 inch in diameter (sizes vary by model) is generally suited to this type of clog. Feed it in carefully and avoid forcing the cable—if it won’t move freely, stop.
A Slow or Clogged Shower Drain
Hair and soap scum are the usual causes here. A drain snake can reach past the drain cover and into the pipe to grab the obstruction. Remove the drain cover before inserting the cable, and wear rubber gloves—the snake will likely pull up wet, unpleasant debris.
A Bathtub Drain That Won’t Clear
Bathtub drains collect hair and soap buildup over time. A snake may help when plunging hasn’t resolved the issue. Keep in mind that bathtub access can be complicated by the overflow plate, so avoid forcing a tool into an unfamiliar configuration.
When a Plunger Has Failed
If a plunger hasn’t worked and the problem appears to be a localized clog, a plumbing snake is a reasonable next step.
The Bob Vila website has a practical breakdown of when to use a plunger versus a snake.
Types of Drain Snakes: Which Is the Right Snake?
Choosing the correct tool matters. Using the wrong type of snake can make a problem worse or potentially damage your plumbing.
Manual Plumbers Snakes
Hand-operated and best suited to small, localized clogs—particularly in sinks and some shower drains. You feed the cable in while rotating a handle or crank. A good option for minor hair, soap, or similar blockages near the drain opening.
Drum Augers / Drain Augers
A drum auger houses the cable inside a drum, providing more cable length and control than a simple handheld snake. Often used for toilets and larger fixtures, drum augers can reach deeper clogs that a small manual snake can’t access.
Toilet Augers
A toilet auger is specifically designed to unclog toilets. Its design protects the porcelain from scratching and navigates the trap correctly—something a general-purpose cable is not built to do.
Electric Drain Snakes
Powered by a motor that rotates the cable, electric snakes are intended for tougher or deeper clogs. Professional-grade motorized equipment can have cables extending up to 100 feet, depending on the machine and application. This is where professional experience becomes especially important—an electric snake in inexperienced hands can damage pipes or get the cable stuck deep in the line.
This Old House explains the differences between drain snakes and other methods to unclog a drain.
How to Snake a Drain Safely
Here is a practical walkthrough of the process—designed to help you handle a minor clog safely, not to replace professional service for anything more complex.
1. Prepare the Workspace
Clear the area around the fixture. Place a bucket and towels nearby to catch water and debris. Have rubber gloves and eye protection ready. Remove the drain cover, stopper, or overflow plate only when appropriate for the fixture you’re working on.
2. Choose the Correct Drain Snake
Match the snake to the fixture and the size of the clog. A small manual snake is different from a toilet auger, drum auger, or motorized snake. Starting with the wrong tool wastes time and can push the blockage further down the line.
3. Feed the Cable Carefully
Insert the cable into the drain opening slowly. The flexible coil is designed to navigate pipe curves, but it needs guidance—not force. Older Maryland homes often have complicated or aging plumbing, which makes caution particularly important here.
4. Rotate When You Feel Resistance
Resistance likely means the cable has reached the blockage. Rotate the handle or crank to engage the clog. The auger head may bore into, grab, or break apart the obstruction. Continue carefully rather than applying pressure.
5. Pull the Cable Back Out
Retract the cable slowly. The snake may bring the clog or debris back with it, or the blockage may have broken into smaller pieces. Keep your bucket and towels close—this part of the job is typically the messiest.
6. Test the Drain
Run water to check whether drainage has improved. Flush with hot water, when appropriate for the plumbing and fixture, to move any loose residue. If water is still slow, backing up, or standing, do not assume the job is done.
Safety Mistakes to Avoid When You Snake a Drain
Never Snake a Drain Containing Active Chemical Drain Cleaner
Do not use a plumbing snake in a drain containing chemical drain cleaner unless those chemicals have been completely and safely flushed away first. The snake can disturb or splash caustic liquid, causing serious burns. Protective gear is non-negotiable if there is any possibility of chemical residue.
Always Wear Protective Gear
Rubber gloves, eye protection, and appropriate clothing are important for every snaking job. Splashback from water, debris, or chemical residue is a real risk.
Do Not Force the Cable
Excessive force can kink the cable, and a cable forced into a pipe can cause damage to older plumbing. If the snake repeatedly gets stuck or won’t advance, stop. This is a signal that the situation may need professional equipment.
Know When DIY Has Gone Far Enough
A drain snake is a useful first step—not a solution for every type of blockage. When the problem persists, repeating the same DIY attempt doesn’t resolve the underlying cause.
The CDC’s healthy water guidelines are a helpful reminder of why sewer backups should always be treated seriously from a health standpoint.

How Long Does It Take to Snake a Drain?
A simple, localized clog may take only about five minutes to address. More complicated clogs can take several hours, depending on location, severity, access, and equipment. The time involved doesn’t necessarily indicate how serious the problem is—sometimes a fast job means a clean, straightforward blockage near the drain opening, while a stubborn situation might indicate something deeper is happening in the line.
When a Drain Snake Is Not Enough
This is the most important part of this guide. A drain snake can open a passage through a clog—but it can’t always solve the underlying problem.
Multiple Drains Are Backing Up
If the sink, shower, bathtub, and toilet drains are all affected at once, the issue is likely farther downstream in the main drain line. Multiple simultaneous backups are a strong sign to call a professional plumber rather than attempting further DIY work.
The Clog Keeps Coming Back
Recurring clogs suggest the root cause hasn’t been addressed. Possible culprits include heavy buildup, damaged pipes, or tree roots working their way into the sewer line. Repeatedly snaking the same drain may only provide temporary relief.
The Drain Is Still Slow After Snaking
Persistent slow drainage after snaking can indicate a deeper issue or a partially cleared blockage. High-pressure jetting—which we use regularly at MD Sewer & Plumbing—can address grease, sludge, and buildup that a basic snake cannot fully remove.
You Smell Sewage or Hear Gurgling
Strange sewage smells, gurgling drains, and water backing up into fixtures are warning signs of a sewer line problem rather than an isolated fixture clog. These symptoms deserve professional evaluation quickly.
There Is Standing Water
Standing water, particularly if sewage or wastewater is involved, is not the time for additional DIY attempts. Call a professional.
You Cannot Access the Clog or Don’t Know the Cause
If the clog is too deep, there’s no practical access point, or the cause is unclear, a licensed plumber with camera inspection equipment can identify exactly what’s happening inside the pipe—without unnecessary guesswork or digging.
The Environmental Protection Agency (EPA) provides useful guidance on protecting your home’s sewer and septic systems.

How to Prevent Future Clogged Drains
Prevention is always less expensive than a repair. Here are the habits that keep drains running freely:
- Use drain strainers in sinks and showers to catch hair and debris before it enters the pipe
- Never pour cooking grease or oil down the drain—let it cool and dispose of it in the trash
- Avoid flushing inappropriate items down the toilet: wet wipes, cotton swabs, and similar products do not break down in sewer lines
- Address slow drainage early, before it becomes a complete blockage
- Consider professional maintenance for older plumbing systems, which are more vulnerable to buildup and root intrusion
- Pay attention to recurring patterns—a drain that keeps slowing down after you’ve cleared it isn’t an isolated event; it’s a warning
HomeAdvisor’s plumbing guide is a good general reference for homeowners looking to stay ahead of problems.
Don’t Let a Clogged Drain Become a Bigger Plumbing Problem
A drain snake is a useful tool. For a minor, localized clog near the surface of a sink or shower drain, it can save you time and money. But snaking a drain clears a symptom, not always the cause. Recurring backups, multiple slow drains, sewage smells, gurgling pipes, standing water, or a clog you simply cannot locate—these aren’t problems a cable solves.

Frequently Asked Questions About How to Snake a Drain
What is the best way to snake a drain?
The best method depends on the fixture and the blockage. A manual drain snake is generally appropriate for a minor sink or shower clog. A toilet auger is the right tool for toilets, as it’s designed to protect porcelain and navigate the trap correctly. A drum auger or motorized electric snake is better suited to deeper or tougher blockages. Matching the tool to the situation is more important than technique alone.
How much does it cost to snake a drain professionally?
Cost depends on the location and severity of the blockage, the equipment required, and whether additional drain or sewer work is needed. We provide free estimates so you know exactly what to expect before any work begins.
What exactly is snaking a drain?
Snaking a drain means feeding a flexible cable (plumbing auger) into the drain opening until it reaches a blockage. You then rotate the cable to dislodge, break apart, or retrieve the obstruction. Once the clog is cleared, the cable is retracted, and the drain is tested with running water.
Is Drano or a drain snake better for a clogged drain?
A drain snake provides a mechanical approach that physically addresses the blockage. Chemical drain cleaners like Drano generate heat to dissolve organic matter, but they can damage PVC and older metal pipes with repeated use, and they often only burn a small passage through a clog without fully clearing it.
We advise Maryland homeowners to avoid relying on chemical drain cleaners for anything beyond minor maintenance. Never use a plumbing snake in a drain where chemical cleaner is still present. For persistent or recurring clogs, professional drain cleaning is far preferable to repeated chemical treatments.
When should I call a plumber instead of snaking the drain myself?
Call a professional plumber when multiple drains are backing up simultaneously, when the clog keeps returning after clearing, when there is standing water or a sewage smell, when you hear gurgling from drains, or when the cause is unclear. These symptoms point to a deeper issue in the main drain line or sewer system—something that requires professional equipment to diagnose and resolve properly.
