How to Use a Drain Snake to Clear Clogged Sinks and Showers

A clogged sink or shower drain can be frustrating, especially when plunging does not solve the problem. A drain snake, also called a plumber’s auger, is a simple tool that can help remove hair, soap scum, and debris from pipes without relying on harsh chemical drain cleaners.

What Is a Drain Snake?

A drain snake is a long flexible cable that feeds into a drain. As it moves through the pipe, it can break up clogs or hook onto debris so you can pull it out. Handheld drain snakes are commonly used for bathroom sinks, tubs, and showers.

Start With the Right Tool

For small household drains, a basic hand snake or drum auger is usually enough. Avoid using a toilet auger in sinks or showers, as it is shaped for toilets. Wear gloves and keep old towels nearby because drain cleaning can be messy.

Remove the Stopper or Drain Cover

Before using the snake, remove the sink stopper, tub stopper, or shower drain cover if possible. Hair often collects right under the cover, so you may be able to remove some debris before snaking.

Feed the Snake Slowly

Insert the cable into the drain and push it forward gently. When you feel resistance, you may have reached the clog or a bend in the pipe. Rotate the handle while applying light pressure. Do not force the cable, because aggressive pushing can damage pipes or get the snake stuck.

Break Up or Pull Out the Clog

Once the snake reaches the blockage, turn the handle to hook or loosen it. Slowly pull the cable back out. You may find hair, soap buildup, or other debris attached to the end. Clean the cable as you remove it.

Flush the Drain

After removing debris, run hot water if the fixture and pipes allow. This helps flush remaining buildup. For bathroom drains, regular cleaning of hair and soap residue can prevent future clogs.

When to Call a Plumber

If multiple drains are clogged, water backs up, sewage odors appear, or the snake does not clear the blockage, the problem may be deeper in the plumbing system. A plumber can use professional equipment to inspect and clear the line.

Final Thoughts

A drain snake is a useful tool for clearing clogged sinks and showers. Use it slowly, avoid forcing it, and clean the drain afterward. For recurring or severe clogs, professional help is the safest option.
