Kitchen sink backed up with food and standing water

Sink full of standing water?

Clogged Kitchen Sink

Kitchen clogs are almost always grease. Fat and oil go down warm, cool in the pipe, and coat the walls until food scraps catch and the line closes. A cable punches through. Jetting cleans the grease off so it doesn't come back next month.

What the plumber does

How the Plumber Handles It

  1. Check the trap and disposal

    The plumber rules out the trap, disposal and dishwasher hose first.

  2. Cable the kitchen line

    A cable reaches through the wall to the clog in the branch line.

  3. Jet heavy grease

    For repeat grease clogs, jetting scours the pipe wall clean.

What's going on

Clogged Kitchen Sink, Explained

Why grease is the problem

Cooking fat, butter, oil and sauces stay liquid while hot, then stick to the pipe as they cool. Each layer catches more. Pouring hot water down the drain only moves the grease a few feet further before it sets again.

Garbage disposals and clogs

A disposal grinds food into small pieces, but starchy and fibrous foods like rice, pasta, potato peels and celery still pack together in the line.

When the clog is further down

If the sink and a nearby laundry or basement drain back up together, the clog is in the shared line or the main, not under the sink.

Do This First

Skip the chemical drain cleaner. It can splash back and it can't clear a main line.

  • Stop running the dishwasher and disposal.
  • Plunge one side while holding the other side closed with a wet rag.
  • Don't pour chemical cleaner into standing water.
  • Wipe greasy pans with paper towel before washing.
FAQ

Clogged Kitchen Sink Questions

Ask the plumber anything else when you call.

Why do both sides of my sink back up?

Both sides share one trap arm. A clog past that point backs up both sides.

Can I pour boiling water to clear grease?

It may help briefly, but the grease usually sets again further down the line.

Does the disposal cause clogs?

It can, when starchy or fibrous food packs together in the pipe.

How do I stop grease clogs?

Let grease cool, scrape it into the trash, and wipe pans before washing.
