Obstructed Vent Pipes:
A blockage in your vent pipes can cause your kitchen sink to gurgle. You can safely expel sewer gas through these vents that connect to your drain pipes.
In most cases, vent pipes run up to the roof, often clogged by dirt, debris, or even animals. The sooner you call a plumber, the better if you have a clogged vent pipe because sewer gases can run straight through your drain pipes.
Food Clogs:
If you use a garbage disposal to dispose of grease, oil, or any other rigid material down your kitchen sink, you must keep those substances away from the removal.
In your kitchen sink, clogs can form if you don’t watch what you’re piling in, trapping air and causing those annoying gurgling sounds.
Although most clogs don’t cause damage immediately, you should still consult a plumber the minute you suspect a clog has developed, as even a small blockage could escalate into something more severe over time.

How To Fix A Gurgling Kitchen Sink
1. Check for Problems in the Installation of the Sink Vent:
The gurgling sound only occurs when you draw water from a kitchen sink, which indicates that it is coming from a vent. The vent was likely either blocked or did not install the p-trap correctly.
If you are using a 1.5-inch drainage pipe, You should install the vent 3.5 feet above the lower portion of your drainage pipe. As such, vents inside the house are freed from the vacuum, which can cause a gurgling sound. Hence, the first step is to check the problem with my kitchen sink.
2. Check the Air Admittance Valve:
An air admittance valve, usually found below sinks, might be installed in a vent in some drains. This valve is virtually pressure-activated, and plumbing systems use them very frequently.
When replacing conventional roof venting and pipe penetration, this is generally utilized. Make sure the air admittance valve is in proper working order.
It is possible that it could be trapped or immobile, causing it to gurgle. A clogged valve could be another cause of your problem, particularly in some rare cases.
The air intake valve may also be the problem. The typical life expectancy for such a valve is at least 20 to 30 years. In the case of a few years of successful operation, there may be problems with the plumbing system.
3. Check for Clogs or Obstructions Inside the Drainage Pipe:
If the drainage pipe doesn’t receive enough air, water flows slowly. Obstruction occurs when residue builds up inside the tube. To avoid blockages, the p-trap should be cleaned as frequently as possible.
First, disassemble a p-trap. Directly under the bucket, place another bucket. Once you have removed the coupling nuts, you can remove the trap from the sink’s tailpiece and the adjacent wall fitting.
After removing the p-trap, buy a new one if the nuts won’t budge or fall apart when you try to move them.
You can get rid of the debris inside the p-trap using a nylon bottle brush or a straightened coat hanger. Ensure it is spotless inside as well as outside before reassembling.
4. Check for External Waste in the Sink Vents:
In addition to collecting external waste, vents that extend to the house’s exterior usually allow bird and plant waste to accumulate.
The debris ends up stacked at the joining points of the vent as it cascades. The Gurgling can be resolved by clearing these vents. Flush the vent with water to solve this problem.
To remove trash stacked inside such vents, water pressure is needed. The problem can also be solved using a plumbing auger.
If you feel a blockage, push the drill as deep into the drain. With the plumbing drill, you can remove debris, creating space in the vents. It’s a fundamental way to avoid gurgling sink.
5. Flush the Sink:
Sometimes all you need to do to fix a gurgling kitchen sink is flush it properly. It will ensure that any remaining residue in the plumbing is discharged into the main sewer pipe.
To altogether remove the blockage, run the water for a couple of minutes. In large sewage pipes, excess water pressure drives waste out of the drainage pipes.
6. Troubleshoot the Main Vent:
It may be necessary to open the central vent to stop gurgling sounds in the sink when draining a bathtub or flushing a toilet. Once this occurs, you will need to clean the vent until the vacuum is strong enough to drain the trap.
You don’t want sewer odours to fill your house. As it is located in most cases above the main bathroom, you need to clean the central vent from the roof. If the opening is blocked, you can spray water into it or utilize a sewer auger.
