Kitchen Sink Clog Repair

A clogged kitchen sink is usually caused by grease, food scraps and soap that harden inside the drain line, often beyond the trap where a plunger can't reach. A plumber clears it with a drain auger sized for kitchen lines, and may recommend jetting if grease buildup is heavy.

Kitchen sinks clog differently from bathroom drains. Grease goes down warm and hardens as it cools, catching food particles along the way. The clog often forms in the horizontal line inside the wall.

If the garbage disposal is involved, the plumber also checks that it is clear and draining properly, since a disposal jam can look like a clogged drain.

Signs of a Kitchen Drain Clog

Kitchen clogs tend to build slowly. Grease coats the pipe, food catches on it, and the sink drains a little slower each week until it stops. A dishwasher backing water into the sink is often the first obvious sign.

  • Standing water in one or both sink basins
  • Water backing up into the other basin or the dishwasher
  • Gurgling when the dishwasher drains
  • Bad odors from the drain

What Not to Put Down a Kitchen Drain

Most kitchen clogs are built from the same few things. Keeping them out of the drain prevents most repeat calls.

  • Grease, oil and fat, even when hot and liquid. Wipe pans with a paper towel first.
  • Coffee grounds and eggshells, which settle and pack into the line.
  • Rice, pasta and other starches, which swell with water.
  • Fibrous scraps like celery, corn husks and onion skins, which wrap around disposal blades and catch other debris.

How a Plumber Clears a Kitchen Sink

The plumber checks the disposal and dishwasher connection first, then clears the trap. If the clog is further in, they run an auger through the line inside the wall, where most kitchen clogs actually sit.

  1. Check the disposal and the dishwasher connection.
  2. Remove the trap and clean it.
  3. Run an auger through the line inside the wall to clear the clog.
  4. Flush with hot water and test both basins and the dishwasher.

What Affects the Cost of Clearing a Kitchen Sink

The price mostly depends on how far into the wall the clog is and whether grease buildup calls for more than a standard auger.

  • Whether the clog is in the trap or further down the line inside the wall.
  • Garbage disposal or dishwasher involvement.
  • Heavy grease buildup that calls for jetting.
  • Access under the sink and to the wall cleanout.

When a Kitchen Clog Needs Same-Day Help

  • Water is backing up into the other basin and the dishwasher.
  • Sink water is coming up in another fixture.

Hard Water and Kitchen Drains

In very hard water cities like Las Vegas and San Antonio, mineral scale builds up inside drain pipes along with grease, narrowing the line faster. A kitchen line that clogs every year or two in these cities often needs jetting, which scours scale and grease off the pipe wall, rather than just snaking.

Before the Plumber Arrives

Kitchen Sink Clog Questions

Can I use a chemical drain cleaner on a kitchen sink?

It's best not to. Chemicals rarely clear grease clogs, can damage pipes and the disposal, and make the repair hazardous if they're still in the line.

Why does my dishwasher drain into the sink?

The dishwasher drains through the sink's plumbing, so a clog downstream makes its water back up into the sink.
