A malfunctioning or blocked venting system can trap air in the pipes. When water is run, the trapped air is forced up through the drain, resulting in bubbles. Vents can be obstructed by nests, debris, or can simply malfunction over time.
Gurgling Sink
This causes a partial clog, trapping the air inside. Once the water rushes in, the air gets released and bubbles through the water, creating the gurgling sound. A blocked vent pipe is another causation for a gurgling sink.
Fill the sink or toilet with water, place the plunger over the drain, and push down and pull up several times. This will create suction and dislodge the air lock. Use a Drain Snake : If the plunger doesn't work, try using a drain snake, a long and flexible tool that can be inserted into the drain to remove blockages.
it's likely a clog underneath the level of this sink. There's nothing attached to his sink that can cause this. It's air trapped in the effluent coming from above that hits a bottleneck below and the air forcing its way back up that causes this.
What does a gurgling drain mean? A gurgling drain usually indicates a blockage in the drain, causing water or air to struggle to flow through. This can happen in sinks, toilets, showers, or even floor drains.

Clogged aerator
When this happens, the faucet will sputter when you turn it on. Debris passing through your pipes increases due to material that's dislodged from the plumbing joints and water main breaks. If the aerator is the cause of sputtering, cleaning it out each month can help prevent this issue.
Evaporated hot water cannot leave the pipes correctly, causing air to get trapped in the piping system. If you have a water heater, air can enter your water pipes due to the water heater's anode rod getting corroded.
Once you find the main water supply, turn it completely off. Turn all faucets to the 'on' position. Once the water supply is off (you might want to double-check this), turn all the faucets in your home to the 'on' position. This will allow for any trapped air to flow through the water lines.
Will an Airlock Eventually Clear Itself? Sometimes, small airlocks may clear themselves as water circulation continues with one or more radiators. However, larger airlocks often require manual intervention, like bleeding the radiators or using a hose to release the trapped air.
Pipe cleaner or sink-cleaning brush: Put the pipe cleaner or sink-cleaning brush into the sink overflow hole, swirl it around, and push the brush in and out to dislodge the gunk.
Call a Professional to Remove Air Bubbles from Water Pipes
Trapped air in water pipes has the potential to inflict lasting damage on your plumbing system.
This is usually caused by a blocked vent pipe. This causes the air to get trapped in the pipe, causing an air lock that can restrict water flow and cause other plumbing problems.
The vented air helps to equalize the pressure on both sides of that trap so that the water in the trap does not get siphoned out. It aids in how well the drain part of the fixture is working. The fixture cannot drain effectively if there are no vent pipes connected to them.
After you turn off your mains water system and drain excess water from your residence, turning the water back on and running your faucets and house appliances that use water can remove air bubbles from the pipes.
Thermostat: A broken water heater thermostat can encourage hot water pockets to form and trap air inside your pipes. In this situation, your water will be too hot, and you'll hear gurgling sounds when using faucets—especially those close to the thermostat.
If your city's working on neighborhood water lines, air can get introduced into the system for the same reasons. Sometimes, air can also enter through leaks in your pipes or as a byproduct of well issues. In these situations, it's best to consult a plumber.
If you hear hissing sounds coming from your plumbing, you may have trouble with high pressure inside the pipes. This might mean overheating in the hot water tank.
During extremely cold weather, ice chunks within water pipes sometimes cause metal pipes to become distorted, producing tears or ruptures in the water line. The "popping" sound of a bursting pipe may not occur in conjunction with a leak because the water has already frozen in the line.
Strong sewage smells are a telltale sign that your toilet vent pipe may be clogged. One of the main jobs of vent pipes is to get rid of those nasty odors and gasses, so if you smell something off, it's time to check it out. If there is a clog in the plumbing vent, those sewer gasses can't escape properly.
If you decide to hire a licensed plumber near you to handle the fix, you can expect to pay between $150 and $200 for this service, although it could be more depending on the severity of the problem.
