Causes of Random Gurgles Kitchen Sink
Clogged Drain Pipes
In most cases, the pipe usually gets clotted with food scraps washed off from plates, oil, soap scum, and hair. These things and other waste can get stuck within the walls of the pipe.
The partly blocked drain will still allow water to run out but the air trapped by the blockage will induce the gurgling noise. It is important to know how to dispose of your garbage since they are primary agents forming clogs inside the pipes. For example, these agents may include grease, egg shells, bones, and hot oil.
Blockage of the Vent Pipe
The drain has a vent pipe that allows sewer gas to escape outside and prevent the formation of a vacuum which may otherwise restrict the flow of water through the drain. Usually, the vent pipe sticks out of the roof and this makes it liable to getting easily blocked by leaves, bird’s nest materials, and other debris.
A Blocked Sewer Line
The sewer line is the pipe responsible for carrying all your wastewater to the municipal sewer system. Just like any other pipe, the pipe in your sewer line can also get clogged. The blockage of the sewer line will affect your entire house, so if you notice many sinks gurgling coincidentally then it’s a sign of sewer line blockage and not just a clog.
Improper Installation of Drain Pipes
If you realize your newly installed kitchen sink makes a gurgling noise then it’s likely the drain pipe was wrongly installed. Sometimes inexperienced professionals underestimate the importance of routing the pipe, the p-trap, and hook-up of the vent pipe. Not paying attention to these things can induce noise if they are not properly installed.

Figure Out the Cause of the Problem
There can be several reasons why your sink may make a gurgling noise. You may have heard the saying that knowing the problem is half the solution. We are going to apply the same principle here. To Fix the gurgling noise from your sink, the wisest thing to do is first to find the root cause of the noise.
Troubleshoot Your Sink Vent
If you hear gurgling noise anytime water is drawn off your kitchen sink then it indicates the problem is from the vents. There is the possibility that there is a blockage or that the vents weren’t fixed correctly from the p-trap.
In case you are using a 1.5-inch drainage pipe, ensure your vent is fitted at 3.5 feet in the lower part of the trap. Doing this will help do away with the vacuum inside the vents, hence stopping the gurgling noise.
On the other hand, if your drain uses a valve instead of a vent to admit air, you need to check out if it got stuck. The valve is usually below or at the back of the sink.
Remove Blockages Inside the Drainage Pipes
Obstructions inside the pipe can induce gurgling noise, as a result of the drainage pipes not receiving enough air. The best way to mitigate this problem is to clean up the p-trap. To do this first you need to disassemble the p-trap. Place a bucket under it.
Then use a plier to remove the nuts connecting the p-trap to the tailpiece of the sink and the adjacent wall fittings.
Finally, take away the p-trap but if the nuts move rapidly apart when you try to move then you need to replace the trap. Use a straightened wire coat hanger to clean inside the p-trap and remove the debris. Make sure both the inside and outside of the p-trappers are spotless, then reassemble it
Check Out for External Waste in Your Sink Vent
Vents that extend to the outside of your house tend to help in the accumulation of external waste matter from bird nest materials and leaves. With time the waste will finally cascade down the vents and wind up being stacked up in the jointing points. Clearing out the vents will help remedy the gurgling noise. You can do this by simply flushing water through the vents opening.
Draining the vents may demand a considerable amount of water pressure to get rid of the garbage stacked within the vent. You can get a plumbing auger to help handle the problem easily. Use the auger to push inside the drains as deep as you until you can feel the obstruction. The plumbing auger will help you pull out the debris and create space in the vents and thus stopping the gurgling noise.
Flush Your Sink
Sometimes the solution can be very obvious. To fix the gurgling noise from your sink all you need to do is simply give your sink a real flush. This will ensure most of the debris in the plumbing system goes into the main sewer pipe. Allow the water to run overly for some minutes to get rid of the blockage entirely. The enormous pressure from the water will push out the waste from the drainage pipes into the sewer pipe.
Trouble-Shoot the Main Vent
Anytime, the central vent is blocked, draining your bathtub or flushing your toilet can induce gurgling noise in the kitchen sink. When this occurs you need to clean the vent until the vacuum is capable of draining the trap.
Another way to clear out the vent is you need to begin from the roof as it is usually fitted above the bathroom. You can either spray water in the vent opening to clear out the blockage or use an auger long enough to push the obstruction into the sewer.
Use a Plunge
You can also plunge to have a blockage issue in your sink. Use a longer plunger to suck out the pipe and relax the plunger to allow the same back in. The plunger will help unclog the obstruction and get rid of the gurgling noise.
Remove the U-bend and Clean the Pipe
One way to remove blockages from your pipe is to take out the u-bend and get rid of e debris. This is what you will need to get going:
- A wire coat hanger
- A plumbers tape
- A bucket
First, put a bucket under the u-bend while you unscrew the pipe.
Unloosen the ends of the u-bend while you collect the water from the impending water in the bucket. Next, use the wire to clean inside the pipe. Then use warm water to push down the debris. Once you’re done with clean- up exercise ensure to reinstall the U-bend and make it watertight using the plumber’s tape.
