Clogged drain slowing your day to a crawl? This complete guide explains how to use a drain snake to clear most sink, tub, and shower blockages at home. We will show you the right tools, step-by-step technique, and common mistakes to avoid so you do not damage pipes. If a clog will not budge or keeps coming back, we also explain when to stop and call a pro for camera inspection or hydro jetting, plus how to save with current specials.
What a Drain Snake Is and When It Works Best
A drain snake, also called a cable or auger, is a flexible steel coil that breaks up and retrieves clogs inside drain pipes. Handheld models work for short runs, like bathroom sinks, while motorized rooters handle longer or tougher lines. Snakes are ideal for hair, soap scum, paper buildup, and small food debris. They are less effective for heavy grease, collapsed pipes, or major root intrusion.
Know your drain type before you begin. Most bathroom sinks and tubs are 1.25 to 1.5 inches in diameter. Kitchen sinks and laundry lines are often 1.5 to 2 inches. Toilets need a closet auger, not a standard snake. If you have repeated backups in multiple fixtures, the main sewer line could be the issue and a cleanout access is the best starting point.
Atlanta homeowners often deal with root growth from oak and sweetgum trees, plus scale in older cast iron found in neighborhoods like Virginia-Highland and Grant Park. A snake can open flow, but persistent root growth usually needs a camera inspection and root-specific treatment.

Tools, Safety, and Setup
Gather the right tools before you start:
- Protective gear
- Nitrile gloves and eye protection
- Old towels and a small bucket
- Tools
- Handheld drum snake or 3 to 8 foot closet auger for toilets
- Adjustable wrench, slip-joint pliers, and a flashlight
- Prep items
- Drop cloths, disinfecting wipes, and a plastic bag for debris
Safety matters. Turn off a disposal at the switch and the breaker. Never put a snake in a running disposal. Remove standing water with a wet vac or cup to see the drain opening. Protect chrome finishes with tape before using pliers. If your sink has a P-trap you can remove, place a bucket below it first.
Two hard facts that help planning: Bardi’s $93 main sewer drain cleaning requires an accessible outside cleanout up to 75 feet per posted terms, and typical drain cleaning jobs take 30 minutes to 3 hours depending on severity.

Step-by-Step: Snaking a Bathroom Sink
Bathroom sinks clog from hair and toothpaste. Here is a reliable method:
- Clear the path
- Remove the sink stopper. Some pull straight up, others require loosening the pivot rod nut under the sink.
- Choose your access point
- Try from the drain opening first. If the trap is packed, remove the P-trap and snake the wall arm toward the larger branch line.
- Feed the cable
- Insert 6 to 12 inches at a time while tightening the drum lock. Rotate the handle clockwise to help the tip bite into the clog.
- Work the clog
- When you feel resistance, gently push and rotate. Do not force it. Alternate push, pull, and twist to break debris.
- Retrieve and flush
- Pull back to remove hair and sludge, then run hot water for several minutes. Reassemble the trap and test for leaks.
Pro tip for Atlanta’s older bath drains: scaly cast iron can snag the cable. Keep rotations steady and avoid sudden torques that could damage thin-walled piping.
"Chaz did an excellent job clearing my drain would definitely use his services again friendly and explained in detail the service."
Step-by-Step: Snaking a Tub or Shower
Tubs and showers collect hair and soap film. Many blockages sit just past the drain shoe or in the trap.
- Remove covers
- Take off the strainer or lift the drain cover. For tubs, remove the overflow plate to access the trip lever linkage if needed.
- Start small
- Try a short, narrow cable or a hair hook tool first. If that fails, move to a handheld snake.
- Feed and rotate
- Guide the snake slowly while turning the drum. Expect the first bend at the trap. If the cable bunches, pull back, straighten, and re-feed.
- Break and pull
- Once resistance eases, pull the cable back and remove debris. Repeat until you feel clear passage.
- Flush and clean
- Run hot water 3 to 5 minutes. Disinfect the work area and reinstall covers.
If you smell sewer gas or see gray sludge returning, the clog may be deeper in a branch line. A camera inspection can identify cracked pipes or root intrusion before damage spreads to ceilings below.
"I would definitely recommend this company for any plumbing services. My technician Mr. Courtesy Thornton was very determined and patient when he provided service to unclog my stubborn sink. He explained everything he was doing and I appreciated his attention to my issue. The same day service was awesome. Thank you!"
Step-by-Step: Snaking a Kitchen Sink
Kitchen clogs are often grease based. Snaking helps, but it may only punch a hole unless you finish with a solid flush.
- Secure the area
- Kill power to the disposal. Bail standing water into a bucket.
- Access the line
- Remove the P-trap and clean it. Snake into the horizontal wall arm toward the main drain, not back toward the sink.
- Work methodically
- Feed 1 to 2 feet, rotate, then pull back to clear the tip. Grease can re-stick. Patience wins.
- Reassemble and flush
- Rebuild the trap, restore power, and run very hot water with a small amount of dish soap for several minutes.
Grease-heavy lines in restaurants need hydro jetting. At home, repeated kitchen backups suggest the line needs professional descaling or jetting to clean pipe walls, not just open a path.
"Very glad that I found Bardi. Sewer line was clogged and they fixed it quickly and completely on the first call out. They had a special that included a camera diagnostic on my line."
Toilets: Use a Closet Auger, Not a Standard Snake
Toilets require a 3 to 6 foot closet auger with a rubber guard to protect porcelain.
- Insert the auger tip
- Guide the guard into the bowl outlet. Extend the cable while turning the handle.
- Break or retrieve the blockage
- Many toilet clogs are paper or small objects. If you hook an object, retract slowly to avoid scratches.
- Test the flush
- After clearing, flush twice. If water rises, stop and try again.
Never use chemical drain cleaners in a toilet. They can damage seals and create a hazard for anyone servicing the line.
"Technician Javier Reyes unclogged my 90 year old Aunt’s clogged kitchen drain and did an awesome job. He was very professional, polite and respectful."
Common Mistakes That Cause Damage
Avoid these errors to protect your plumbing and your hands:
- Forcing the cable
- Excess pressure can kink the cable or crack brittle PVC or old cast iron.
- Skipping trap removal
- Pushing through a packed trap only compacts debris. Remove and clean it.
- Using the wrong tool
- A standard snake in a toilet risks scratches. Use a closet auger.
- Ignoring cleanouts
- Main line issues are best attacked from an accessible outside cleanout for a straighter path.
- Stopping after you “pop” the clog
- Always flush with several minutes of water. Consider an enzyme drain treatment for maintenance.
In Atlanta clay soils, settled ground can bellies older sewer lines. A snake may clear today, but standing water in a belly will collect solids again.
"Shelby and Bradley were courteous, thoroughly professional, knowledgeable and diligent while clearing my sewer drain line!"
When to Stop and Call a Pro
Call a licensed plumber if you notice any of the following:
- Multiple fixtures backing up at once
- Standing water returns within 24 hours
- You cannot locate or access a cleanout
- Old cast iron with heavy scale or rust flakes
- Suspected tree roots or a broken pipe
A professional can run a high-definition camera to pinpoint the problem and recommend the right fix. Bardi performs camera inspections to identify blockages, cracked pipes, and root intrusions, then provides options like hydro jetting, minimally invasive root treatment, or trenchless repair if needed.
Two more hard facts to set expectations: Bardi lists $0 service fee for main drain cleaning on some specials, and many repairs include a 2-year warranty with a Lifetime Workmanship Guarantee. Terms apply and will be reviewed before work begins.
Snake vs Hydro Jetting vs Excavation
Snaking is the first line for simple clogs. Hydro jetting uses a high-powered water stream to slice through heavy grease, scale, and roots while cleaning pipe walls. It is ideal for repeat kitchen clogs or long runs with buildup. If a pipe is collapsed or severely offset, excavation or trenchless replacement may be required. Bardi uses trenchless technology whenever possible to reduce yard damage and downtime.
In tree-lined areas of Sandy Springs, Roswell, and Marietta, roots often invade older clay or cast iron joints. A camera inspection followed by targeted jetting and root treatment usually restores flow without digging. If a section is beyond repair, spot-lining or trenchless replacement can solve the problem with minimal surface disruption.
Preventative Maintenance That Actually Works
Prevention saves time and money. Use these habits:
- Weekly
- Run hot water through kitchen drains after greasy meals.
- Monthly
- Use a safe enzyme treatment to reduce biofilm in bathroom drains.
- Quarterly
- Clean sink stoppers and shower strainers to catch hair and debris.
- Annually
- Schedule a camera inspection for homes with past root issues or older piping. Consider a maintenance plan for reminders and discounts.

Frequently Asked Questions
How do I know if I should snake the drain or call a pro first?
Try a snake if one fixture is slow and there is no sewage backup. If multiple fixtures back up or the clog returns quickly, schedule a camera inspection.
Can a drain snake damage my pipes?
Yes, if forced. Use gentle rotation and steady feeding. Avoid excessive torque on old cast iron and always use a closet auger for toilets.
How far should I snake a sink line?
Feed until resistance eases and you feel open passage, often 6 to 15 feet for sinks. Do not force beyond tight bends. Flush with hot water after.
Will hydro jetting work better than snaking?
Snaking opens flow. Hydro jetting cleans pipe walls and removes heavy grease, scale, and roots. It is better for repeat clogs and long, dirty runs.
What if I do not have an outside cleanout?
A plumber can attempt from a fixture, but pricing and results vary. Installing a proper cleanout improves access, cost, and long-term success.
In Summary
Using a drain snake the right way clears most sink, tub, and shower clogs without damage. When backups spread to other fixtures or return fast, stop and call a pro for camera inspection or hydro jetting.
