Why Is My Kitchen Sink Gurgling?

It’s frustrating enough doing all the dishes that the family seems to leave in and all around the kitchen sink, but when you finish the dishes and drain the sink and it gurgles back at you, that’s maddening! Why is the kitchen drain gurgling like that?

Common Reasons Why Your Kitchen Sink Is Gurgling, Include:
  • Clogged drain pipe
  • Blocked vent pipe
  • Improper drain pipe installation

Now, let’s figure out what you can do to get your kitchen sink to stop gurgling.

Clogged Drain Pipe

Even without a garbage disposal, there’s a lot of food that ends up being rinsed off of plates and going down the drain. Certainly, food debris (and hardened grease for those who think rinsing frying pans in the sink is a good idea) can clog the drain over time.

  • If the drain pipe becomes┬ápartially obstructed, the water will still drain but air will get trapped at the obstruction and make that gurgling sound.
  • If bubbles come up when the dishwater is draining, this is the likely cause.

Don’t run out and buy a liquid drain cleaner. These products are harsh chemicals that can be dangerous. And in many cases, they do more damage than good, especially to older drain pipes. Unless you want to invest in a proper plumbing snake and other equipment, it’s best to call a plumbing professional to clear the drain pipe for you. Even if it’s just a little gurgling and not slowing the drain down much, it’s best to get it dealt with before it becomes a bigger obstruction.

Blocked Vent Pipe

This is the classic cause of the gurgling sound you hear after the sink has drained, maybe even a few seconds after the water has drained.

  • A vent pipe is attached to the drain pipe under your sink to allow sewer gas to escape.
  • These vent pipes run to the roof of your house and vent outside, but they can become blocked by leaves, dirt or nesting material from birds.

The vent pipe can sometimes be roughed in behind the cabinetry or in the wall so it can be hard to find. The best solution to this gurgling problem is to call a plumber who can quickly verify the problem and then clear that vent pipe properly.

Incorrect Drain Pipe Installation

If a new sink drain is gurgling, it’s probably because the drain pipe has not been properly installed. Non-professionals sometimes do not understand the importance of the P-trap, routing of pipes and the proper hook-up of a vent pipe. It would be best to get a professional plumber to correct the plumbing in this case.

Get A Professional Diagnosis From A Plumber

If your kitchen sink is gurgling, it’s telling you there’s a problem with airflow in the drain pipe. There could be a clog or blockage or even improper installation.
