Here's the correct way to use a plumbing snake.

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 that it can make its way through the drain to reach the clog.

Step 3: Hook the material.

When you feel resistance, you may be at the point of 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 handle for the cable to either pull up what’s clogging the drain or break apart the clog. Be gentle to avoid breaking the auger.

Step 5: Repeat as necessary.

You can repeat the above steps as frequently 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 ensure chemical drain cleaners (and wastewater) don't splash into your eyes or come 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.
