Quick answer

Most kitchen sink clogs are caused by grease, oil and food particles that cool and stick inside the drain line, often past the trap inside the wall. A plunger rarely clears them for long. Cleaning the line with a drain cable, or with hydro jetting for heavy buildup, removes the blockage and more of the coating that causes the clog to return.

The kitchen sink sees more grease and food waste than any other drain in a home. Even with a garbage disposal, small particles combine with cooking fat and soap to form a sticky layer that narrows the pipe over time. Double sinks and dishwashers that share the same drain make the problem more noticeable: water may rise in one basin when the other drains or when the dishwasher pumps out.

Kitchen clogs often sit beyond the P-trap, in the drain arm or the branch line inside the wall, which is why removing and cleaning the trap does not always fix them.

Common kitchen sink drain problems

  • Water stands in one or both basins after the faucet is turned off
  • Water backs up into the other side of a double sink
  • The dishwasher leaves water in the bottom or backs water into the sink
  • A sour or rotten smell comes from the drain or disposal
  • The disposal runs but water still drains slowly
  • Gurgling sounds after draining a full sink

What causes kitchen drain clogs

Fats, oils and grease (FOG)

Grease goes down as a liquid and hardens as it cools in the pipe. It traps food particles and builds up in layers.

Food scraps and starches

Rice, pasta, potato peels and similar foods swell with water and form a paste.

Coffee grounds and eggshells

These do not break down and settle in low spots, especially when combined with grease.

Disposal overload

Feeding a lot of waste at once, or running the disposal without enough water, pushes clumps into the line.

Soap and mineral buildup

Soap residue binds with minerals in hard water and adds to the coating inside the pipe.

Shared lines in apartments

In multi-unit buildings, a kitchen stack can carry waste from several units, so buildup further down affects more than one sink.

How kitchen sink drains are cleaned

Trap and drain arm cleaning

Removing and cleaning the P-trap and checking the drain arm for buildup close to the sink.

Cable cleaning

A drain machine cable runs through the branch line to break through the grease clog.

Hydro jetting for heavy grease

For lines coated with grease, jetting can clean the pipe walls more thoroughly. See hydro jetting.

Camera check for repeat clogs

When the kitchen line clogs often, a camera inspection can show whether a sag or damaged section is holding grease.

When to call a professional

  • Water will not go down at all in either basin
  • The sink backs up every time the dishwasher runs
  • You have cleaned the trap and the clog is still there
  • Other drains, such as a nearby laundry or floor drain, also drain slowly

Tips to help prevent future problems

  • Pour cooled cooking grease into a container and put it in the trash
  • Scrape plates into the trash or green waste before rinsing
  • Run plenty of cold water while using the disposal and for a few seconds after
  • Keep coffee grounds, eggshells and fibrous peels out of the disposal
  • Use a sink strainer in basins without a disposal

Frequently asked questions

Can I pour boiling water down a clogged kitchen sink?

Hot water can soften light grease, but it rarely clears a real clog, and very hot water can damage some plastic fittings and sink seals. It will not remove grease that has built up further down the line.

Why does my kitchen sink back up when the dishwasher runs?

The dishwasher usually drains into the sink drain or disposal. If the kitchen line is partly blocked, the dishwasher's water has nowhere to go and rises in the sink.

Is a garbage disposal clog the same as a drain clog?

Not always. A jammed disposal will hum but not spin. A drain clog lets the disposal run but water still will not drain. The two can happen together.

Do restaurants in Whittier need grease control?

Food service businesses are generally expected to control grease through grease traps or interceptors and regular maintenance. Check with your local sewer agency for the rules that apply to your property, and see our commercial drain cleaning page.

How often should a kitchen drain be cleaned?

There is no single schedule. Homes that cook with a lot of oil, or that have had repeat kitchen clogs, may benefit from periodic cleaning. Ask the technician what they saw in your line.
