Kitchen lines clog differently from bathroom lines. Bathroom clogs are usually hair close to the drain opening. Kitchen clogs build slowly further down the pipe, where warm greasy water cools and leaves a layer behind each time the sink is used.
Double sinks, dishwashers and garbage disposals all share the same kitchen branch. When the dishwasher drains into the other sink bowl, or water rises in one bowl while the disposal runs, the blockage is past the point where they join.

Double sinks, dishwashers and disposals
When one side of a double sink backs up into the other, the clog is usually below the point where the two drains join. If the dishwasher drains into the sink, the clog is in the shared line. A disposal that's run without enough water can also leave a slug of ground waste in the trap arm.
Plunging a double sink works only if you seal the other drain with a wet rag or a second plunger. Never plunge after using a chemical drain cleaner; it can splash back.
Grease: the main kitchen drain problem
- Let pans cool and wipe grease into the trash before washing
- Don't pour bacon fat, oil or gravy down the drain, even with hot water
- Use the disposal sparingly for starchy and fibrous waste
- If the kitchen line clogs more than once a year, ask about jetting the line
How a plumber handles it
- 1Check the trap and disposalA jammed disposal or full trap is ruled out first.
- 2Cable the branch lineA small drum machine clears the clog from the trap arm or a cleanout.
- 3Jet if grease-coatedWhen a line has been cabled before and keeps closing, jetting scours the walls.
- 4Test with full flowBoth bowls and the dishwasher are run together to confirm.

Kitchen Drain Cleaning FAQs
Why does my kitchen sink keep clogging?
Grease and starch coat the pipe wall and narrow it. Cabling opens a hole through the buildup, which closes again. Jetting removes the coating.
Why is my dishwasher water coming up in the sink?
Both drain into the same kitchen branch. A clog past the point where they join sends dishwasher water back up through the sink.
Can I pour boiling water down a clogged kitchen drain?
It can soften a small grease plug, but it won't clear a hardened clog and can damage PVC joints or a porcelain sink. Use it sparingly.
Is a garbage disposal causing my clogs?
Often. Disposals grind food small, but the particles still settle in the pipe if not flushed with plenty of cold water.
