What Are Sink Vents? As water passes through the drain and down into the trap, it needs to pull air from somewhere behind it. Sink vents help supply the drain with the air it needs and if there isn’t enough air from the vents, or there are no vents at all, air will be pulled from the sink. If the sink vents are clogged, or are not working properly, the gurgling

Your bathroom sink makes a gurgling sound due to the presence of air in in your drain. This air escaping from the drain is not supposed to be there to begin with. When the inside the pipes can’t escape and ends up putting pressure on the draining water, it makes a gurgling sound.

Common Causes of Sink Gurgling Noise The P-Trap is Broken In this instance, gurgling is caused by air escaping the drain when it shouldn't. If the p-trap is blocked, it forms a vacuum that pulls on the water in the p-trap and makes air movement in the pipes audible.

In most cases the reason will be a partial blockage in the drain. In some cases, your sink drain will even make a gurgling sound when you use your shower or toilet – if the drains are somehow connected to each other. Water stalls at the point of congestion and this will make the water only drain slowly.

If turning on the sink in the kitchen causes a gurgling sound in your bathroom, then the clog may be in your main sewer line. In this case, the gurgling sound is the result of air or gas bubbles getting trapped in your drain lines because they can’t reach your plumbing vent.

Gurgling drains are usually caused by obstructions in the venting system. The gurgling sound is caused by air being forced through water in your drain trap. It’s like pouring milk too quickly (glug, glug glug). While the gurgling sound often comes from the shower/tub, it can also come from your vanity sink or toilet.

This encourages the water to run very quickly and sometimes this causes a vacuum behind the flow. This vacuum sucks at the water which remains in the trap. Most often this "sucking" causes the water in the trap to bubble and gurgle – hence the gurgling noise.
