How to Unclog a Drain Fast

Most single-fixture clogs can be cleared in about half an hour with a plunger and a hand snake. The trick is knowing which kind of clog you have, because the same tool does not work on hair, grease, and a root-filled sewer line.

Start With the Fixture

Kitchen sink

Grease and food scraps are the usual cause. Remove the stopper or strainer, plunge with a cup plunger, and if the sink has a double basin, plug the second drain with a wet rag first or the pressure escapes. If a garbage disposal is attached, make sure it is off and run the plunger over the disposal side. Do not put hands in the disposal.

If plunging does not help, put a bucket under the P-trap (the U-shaped pipe), unscrew the two slip nuts, and clean it out. A lot of clogs sit right there.

Bathroom sink and tub

Hair and soap. Pull the stopper out (many lift or twist), clear what is wrapped around it, and use a plastic barbed zip tool to pull hair from the drain. Rinse with hot tap water afterwards.

Toilet

Use a flange plunger, not a cup plunger, and make sure the water level covers the cup. If it keeps rising, close the supply valve behind the toilet. A closet auger works better than a hand snake because it will not scratch the porcelain.

Home Methods That Work and Ones That Do Not

Hot tap water (not boiling, especially with PVC or a cracked porcelain bowl) can move a light grease film.
Baking soda and vinegar loosens light buildup. It will not move a hard clog.
A hand-crank snake reaches clogs within about 25 feet of the opening.
Avoid caustic drain cleaners. They can damage fittings and they are dangerous for whoever opens the trap afterwards.

When It Is Not the Fixture

Look at the lowest drain in the house and any other drain, not just the slow one. Signs the main line is the problem:

More than one fixture is slow or backing up at once.
A toilet flush bubbles in the tub or a floor drain.
The washing machine drains and water appears in a shower or tub.
Gurgling from drains far from the clog.
A sewage smell in the yard or damp patches in the grass over the line.

In a typical Lawrenceville yard there is a capped cleanout pipe near the house. If you unscrew the cap and it is full, the blockage is out in the line, probably roots or a collapsed section, and a sink snake will not fix it.

We connect you with a local plumber who handles drain cleaning and hydro jetting, which uses high-pressure water to scour the pipe.

Ask the plumber what method they plan to use and for the price before work starts. A camera inspection afterwards is worth asking for if the clog has come back.

Keep Drains Clear

Strainers in every sink and tub.
Pour grease into a can and put it in the trash, not down the sink.
Run hot water for a bit after washing dishes.
Flush toilet paper only. Wipes labeled flushable still clog lines.
Keep fibrous scraps like celery, potato peels and coffee grounds out of the disposal.

FAQ: Common Questions About Unclogging Drains

What is the fastest way to unclog a drain?

A plunger, used correctly. Fill the sink or tub with enough water to cover the cup, block the overflow with a wet rag, and push and pull firmly for 15 to 20 seconds. If that fails, a hand snake or a plastic hair-catching tool is the next step.

Does baking soda and vinegar really unclog drains?

It loosens light buildup and freshens a slow drain, but it will not clear a real blockage. Pour half a cup of baking soda, then half a cup of vinegar, wait 15 to 30 minutes, and flush with hot tap water.

Are chemical drain cleaners safe?

Not a good idea. They can damage older pipes and fittings, burn skin if they splash back, and leave caustic water standing in the line for the next person who has to work on it. If one has already been poured, tell the plumber.

When should I call a plumber for a clogged drain?

When more than one fixture is backing up, when sewage or gurgling shows up at the lowest drain in the house, when the clog comes back within weeks, or when a snake will not get through. Those usually point to the main line.
