Here's the correct way to use a plumbing snake

When you have a clogged toilet or need to unclog a sink drain, you can use a closet auger or drain auger — also known as a plumbing snake — to do the job.
A plumbing snake is a long, flexible metal cable that can be up to 50 feet long to reach even the most difficult clogs. Once the snake has reached the clog, it can push it through to break it apart or pull out whatever was clogging the drain.
How do you use a plumbing snake? This guide explains how to use it to clean out clogged drains.
Step 1: Create a clear pathway
If you’re going to snake a drain, first remove the pop-up stopper or strainer cover. If that’s not possible, remove the P-trap from the sink cabinet to insert the snake.
If you’re using a closet auger in a toilet bowl, you can insert the snake directly into the bowl.
Step 2: Insert the snake
Insert the snake into the pipe or drain. Twist the tool so it can make its way through the drain and reach the clog.
Step 3: Hook the material
When you feel resistance, you may be at the clog. Push the tip deeply into the clog so you can hook the material.
Step 4: Turn the cable
Once you’ve hit the clog, turn the cable handle to pull up what’s clogging the drain or break apart the clog. Be gentle to avoid breaking the auger.
Step 5: Repeat as necessary
Repeat the steps above as often as needed if you believe there are additional clogs.
Step 6: Test the water flow
When you think you’ve removed all blockages, reassemble the drain. Run hot water through the drain or flush the toilet to see if the snake was successful. Clean the snake cable after the process is complete.
Mistakes to avoid when using a plumbing snake
There are some things you’ll want to avoid to ensure the snake works. Keep these common mistakes in mind so you can set yourself up for success:
- Not wearing safety equipment. Eye protection and cleaning gloves help keep chemical drain cleaners and wastewater from splashing into your eyes or coming into contact with your skin.
- Moving too fast. Slow and steady is best when you’re using a plumbing snake. If you rush through the process, you could break the snake and miss the clog. When you’re pulling clogged material out, be careful not to pull or twist too strongly so you don’t break the snake.
- Not using the right auger. Standard or plastic augers could damage the porcelain finish on a toilet. If you’re snaking a toilet, look specifically for a closet auger or toilet auger.
If you’re purchasing an auger for the first time, talk with a home improvement professional about what they recommend for the appliance you’re working on. Some stores will rent augers so you don’t have to purchase one.
Can snaking make a clog worse?
In some cases, especially when using the wrong snake, a snake could make the clog worse. This may happen if the snake ends up jamming the clog tighter into the pipe. Again, consult with a home improvement store professional about which tool they recommend using.
When to hire a plumber to unclog your drains
Sometimes, snaking a drain yourself won’t be enough to unclog it. You may need a longer snake or one that’s used by professionals for the specific type of clog you have.

FAQs
Can a drain snake break a pipe?
When used improperly, drain snakes could scratch, punch holes through, crack, or damage a pipe. Some augers are powerful enough to completely break a pipe, especially one that’s older and already damaged.
Why won’t my snake go down the drain?
Drains twist and turn, so a snake will need to follow the drain path to reach the clog. If your snake isn't moving down the drain, it may not be long enough or you may have hit a bend. Continue applying pressure and turning the handle to move the cable through the drain.
