The dishes are done, and waste water is going down the drain. Then you notice a glug-glug-glug coming from the drain. Why does your sink gurgle? Is your gurgling sink dangerous? Your gurgling sink most likely does not pose a serious hazard, but the gurgle is a tell-tale sound indicating something is wrong. In this article, we’ll find out why and how to address the gurgling sink.
The Source of the Sound
The answer to why is my sink gurgling is trapped air. Because of a blockage in the pipe or an issue with the vent pipe, air bubbles or air pockets gather in the pipes. As water is forced into the air space and the air moves, it creates the ‘glugging’ sound of a gurgling drain.
Why Is My Kitchen Sink Gurgling?
Drain
Pieces of food, hair, grease, and other elements can build and restrict water flow over time. This can trap air and result in gurgling.
P-trap
Designed to keep gasses from coming up from the sewer, the P-trap, or P shaped pipe under the sink, can develop a blockage and trap air.
Air vent pipe
Designed to balance air pressure in the pipes, the vent can become blocked. That creates a suction with trapped air and gurgling appears.
Sewer lines
A more drastic problem is if there is a blockage in the main sewer line. This can cause a gurgling problem for all of the drains in your home.
