How-To: Unclog a Drain

Clogged drain sink requiring unclogging repair

Quick Summary: Most drain clogs can be cleared in 10-20 minutes using a drain snake or simple plunger. Start with the gentlest method and work up to more aggressive tools only if needed.

Why Unclog Your Drain?

A slow or completely blocked drain isn’t just annoying, it’s a breeding ground for bacteria and can cause water damage if it overflows. Most clogs are caused by hair, soap scum, food particles, or grease buildup that accumulates over time.

The good news? You don’t need to pay a plumber $150 for a 10-minute job. Most drain clogs can be cleared with simple tools and a little patience.


What You’ll Need

Drain Snake Tool
FlexiSnake Drain Weasel, Perfect for hair clogs and easy to use. Made in USA with 5 disposable wands.
Complete Kit
25-Foot Drain Auger Kit, Heavy-duty option for stubborn clogs. Includes gloves and plastic hair snake.

Also needed: Rubber gloves, bucket or large bowl, old towels

Tip: Start with the gentlest method first. You can always escalate to more aggressive tools if the simple fixes don’t work.


Step 1: Remove Standing Water

Clear any standing water from the sink or tub using a bucket or large bowl. You need to see the drain opening to work effectively.

Wipe around the drain with a towel to give yourself a clean workspace.


Step 2: Remove the Drain Cover

If your drain has a removable cover or stopper, take it out. Most bathroom sink stoppers lift straight up or unscrew counterclockwise.

For shower drains with screws, use a screwdriver to remove the cover. Keep the screws in a safe place.


Step 3: Try the Manual Method First

Put on rubber gloves and use your fingers to pull out any visible hair, soap buildup, or debris near the surface. You’d be surprised how often this simple step solves the problem.

If you can see the clog but can’t reach it, try using needle-nose pliers or tweezers.


Step 4: Use a Drain Snake

Insert the drain snake into the drain opening. For the FlexiSnake, simply push it down and rotate the handle clockwise 3-4 times.

Slowly pull the snake back out. The rotating action should grab hair and debris. You may need to repeat this process 2-3 times to get everything.


Step 5: Flush with Hot Water

Run hot water for 30-60 seconds to flush away any loosened debris. If water drains quickly, you’ve solved the problem.

If water still backs up, repeat the snaking process or move to the more powerful auger for deeper clogs.


Step 6: Test the Drain

Fill the sink or tub with a few inches of water, then release it all at once. The water should drain quickly with no backing up.

Replace the drain cover or stopper and test normal water flow one more time.


When to Call a Pro

If the clog persists after trying these methods:

  • The clog is in the main sewer line (multiple drains backing up)
  • You hear gurgling sounds from other drains when you run water
  • Water is backing up into other fixtures
  • You’re uncomfortable using drain cleaning tools
  • The problem keeps returning every few weeks

FAQ

How often should I clean my drains? Use a drain snake monthly in high-use drains like bathroom sinks and showers to prevent major clogs from forming.

Are chemical drain cleaners better than snaking? No. Chemical cleaners can damage pipes and are harsh on your plumbing. Physical removal with a snake is safer and more effective for most clogs.

Can I prevent drain clogs? Yes. Use a drain strainer to catch hair and debris, avoid putting grease down kitchen drains, and run hot water after each use to clear soap residue.

What if the snake gets stuck? Don’t force it. Gently rotate back and forth while slowly pulling up. If it won’t budge, call a plumber rather than risk damaging your pipes.
