How to Use a Drain Snake Properly

A drain snake (also called a plumber's snake or auger) is an essential tool for clearing stubborn clogs. Here's how to use one safely and effectively.

Types of Drain Snakes

Before You Start

Gather Supplies:

• Appropriate snake for drain type
• Rubber gloves
• Safety glasses
• Bucket
• Rags or old towels
• Flashlight

Preparation Steps:

• Remove drain cover or stopper
• Clear visible debris from drain opening
• Place bucket and towels to catch water
• Run hot water to warm pipes slightly

Using a Hand Crank Snake

Step-by-Step Process:

• Insert the snake
• Push the cable into the drain opening
• Keep 6-12 inches of cable exposed outside

• Start cranking
• Turn the handle clockwise while pushing forward
• Maintain steady pressure
• If resistance occurs, continue cranking

• Navigate bends
• P-traps and bends create resistance
• Reduce pressure, keep cranking
• The cable will work through

• Reaching the clog
• Significant resistance indicates the clog
• Rotate the cable to break up or grab debris
• Push through if possible

• Retrieve the cable
• Continue cranking while pulling back
• Bring debris out with the cable
• Clean cable as it emerges

• Test and repeat
• Run water to test drainage
• Repeat if needed
• Multiple passes may be required

Using a Toilet Auger

Different Technique Required:

• Pull auger cable back into housing
• Insert curved end into toilet bowl
• Position tip into drain opening
• Crank handle while pushing down
• When resistance is felt, continue cranking
• Retrieve by reversing direction
• Flush to test

Important: Never use a regular drain snake in a toilet - it will scratch porcelain!

Common Mistakes to Avoid

Force Problems:

• Don't force the cable - can damage pipes
• If stuck, reverse direction and retry
• PVC pipes can crack under pressure

Wrong Tool:

• Using sink snake in toilet damages bowl
• Using short snake for deep clogs wastes time
• Power augers can damage small pipes

Safety Issues:

• Not wearing gloves (cables are dirty)
• No eye protection (debris can spray)
• Ignoring repeated resistance (may be pipe, not clog)

When to Stop and Call a Plumber

• Snake won't advance after multiple attempts
• You hit something hard (could be pipe)
• Water backs up in other drains
• Clog immediately returns after clearing
• You've gone full length without finding clog

Maintenance Tips

After Each Use:

• Clean cable thoroughly with soapy water
• Rinse and dry completely
• Apply light oil to prevent rust
• Coil loosely in dry storage

Cable Care:

• Replace frayed or kinked cables
• Sharpen or replace cutting heads
• Store in dry location
