The P-trap is the U-shaped pipe under your sink that generally contains water to block odors and gases from your sewage. It also serves as a catch tray for items that may fall into your sink that should not have. Your kitchen sink will start to gurgle when your pipes are clogged, causing the P-trap to trap air.
This is due to a partial clog in the drain pipe, in which a plumbers snake should be used to help remove the clog. Water runs in the path of least resistance, so a clog in the main drain pipe that is just below the lower sink, will force the water back to the sink rather than down the drain pipe.
Many homeowners deal with clogged sinks that result from food particles, grease, and other debris stuck in the pipes. Over time, these materials can accumulate and lead to blockages, restricting water flow and causing backups.

Slow drains may not always be due to clogs.
Plumbing vents, soap buildup, and garbage disposal malfunctions are among the most common culprits.
Air bubbles in your plumbing system can cause kitchen sink gurgling sounds. These bubbles often happen when there is air trapped in the pipes. If you have damaged or incorrectly installed plumbing, you might hear your sink make “burping” sounds.
A sputtering sink can be a bothersome problem, but with proper troubleshooting, it can be resolved. Air trapped in water pipes, clogged aerators, and plumbing leaks are common culprits behind the sputtering issue.
Air in the Water Line
A frequent culprit behind a sputtering faucet is the emergence of air bubbles within the water pipes. This issue commonly arises during winter, when freezing temperatures prevail, or during times of heightened water usage, such as scorching summer heatwaves.
Pour one cup of fresh baking soda down the drain, followed by one cup of white vinegar. Place a rubber stopper or other sink hole cover over the drain opening. Wait 15 minutes to allow the vinegar and baking soda to unclog your drain, Then take out the drain cover and run hot tap water down the drain to clear the clog.
There are two main ways that you can deal with a backflow problem: air gaps and backflow prevention devices. You can install air gaps on sinks, tubs, and toilets. They are easy to install and require no additional equipment other than the pipe.
In most houses, the drain line for each sink extends horizontally back into a wall, where it fits into a sanitary tee. One outlet on the tee extends downward into a vertical drain line, and the other extends upward into a vent system that is open to the outside air.
So, when you notice water backing up through the plug hole instead of smoothly draining away, it's a cause for concern. This unexpected issue is a clear sign of a problem in your drainage system, most likely a stubborn blockage.
The Short Answer Is: Drano and similar chemical drain cleaners can be harmful to home drain pipes as they contain corrosive chemicals that may deteriorate pipes over time, especially if used frequently.
Signs of a clogged vent include slow-draining fixtures, gurgling sounds in the plumbing, or sewer gas odours around sinks and drains. A clogged vent is often located on the roof, but it can sometimes be obstructed lower down the line as well.
What Causes a Faucet to Spit Water? Most times, a surprise spitting faucet is the result of a pressure change, which most commonly means there's air trapped somewhere in your plumbing. Aside from spitting, you may also hear tapping or banging inside the walls when your water is in use. Don't worry, that's no ghost!
Your plumbing system relies on vent pipes to allow air into the drain lines. When these pipes get blocked by debris, leaves, or even bird nests, it can create negative air pressure, causing your sink to gurgle.
Add baking soda and vinegar: First, remove any standing water from your sink. Then, pour a cup of baking soda down your drain, followed by a cup of vinegar. Wait about 10 minutes. Finally, flush the drain with hot water.
Pour some baking soda down your drain and then pour boiling water down after. Sometimes this will clear the clog. Use a plunger on your sink drain to try to force the clog out of the trap.
If you have a two-story home, go upstairs to locate the pipe. You can verify whether a pipe is a vent pipe by listening as someone flushes the toilet. If the pipe amplifies the flushing sound, it's likely the vent pipe. To find the plumbing vent on the roof, look for a pipe extending about six inches from the roof.
