Why is My kitchen sink Gurgling and How can I Fix it

Gurgling is an indicator that your kitchen sink is experiencing some serious problems on drainpipes.

This irritating noise is caused by air bubbles that are flowing in your sink drain as a result of the blockage. If the sink drain pipe is blocked, air bubbles arise and they eventually move out through the sink opening.

Apart from the drain pipes, the farmhouse sink is also fitted with a ventilation pipe that extends out of the roof. These pipes are installed to exit gases outside the house. These vents can also be blocked.

The gurgling sound that comes from your kitchen might call for a drain cleaning or some serious repair. Of all the drains you might have in your home or farmhouse, your kitchen sink is the busiest system.

Suppose you own a garbage disposal, your sink drain handles even much task. In whatever way, your sink is expected to work extra hard.

Remember there is no day you will spend without food. After every meal, you must clean your dishes. This means your kitchen drain receives much work to handles on a daily basis.

Hearing a gurgling sound every time you wash your plates can be an irritating experience in the house. This may soon result in a bigger plumbing assignment.

Probable Cause of Gurgling Your kitchen Sink

To understand what causes gurgling sound in your sink, you must be well conversant with the drainage system.

When you drain water after washing your dishes, the water passes through the pipe and air replaces it immediately. If this procedure fails at any point, water would just remain stagnant in the pipe.

In most cases, a suitably designed pipe has a vent system which allows air to replace the drained water from the sink. This means that air circulates conveniently inside and out of the pipe, and no vacuum is formed.

Though, if air cannot travel comfortably inside the pipe, or is blocked to get out of the pipe, a vacuum will be formed. This is what results in a gurgling sound. You may experience this problem inside any other drains in your house.

When you wash many plates with food remains, there is a possibility of some debris jamming your sink pipes. Things like small bone particles, egg shells, hot oil, or grease can easily pass through the vents, but they are likely to clog inside the pipe.

The pillage of such particles causes a blockage at the drainage pipe. This obstruction further prevents air from passing through the pipe, thus produces a gurgling sound when water is flushed from your kitchen sink.

A sink that releases bubbles when water is drained is a good indicator of this problem. If you don’t solve this problem at the right time, it may lead to a full blockage that may not allow you to drain your kitchen's sink.

Blocked vents that are not spacious enough causes gurgle sound when water is drained from the sink. You should understand that there is a vent pipe linked to the drainpipe below your sink that permits sewer gas to run off.

This pipe extends to the roof and can be clogged by particles that can drop from the top of the building. This can force sewer gas back into the drain pipe, which triggers the gurgling sound infuriating your ears.

As a result, it is advisable to contact plumbing experts to unclog your pipe right from the top of the roof.

The leakage in the sink strainer can cause gurgling when you drain your kitchen sink. Sink strainer can easily rot as a result of oil and salt you pour through the sink.

You need to identify the source of the outflow and make sure that the leaking spaces are caulk. If the leaking part is a joint to your sink drainage pipe, you should plan to replace the sink strainer. This must be done under the support of a plumber.

How to Fix a Gurgling Sink

If you hear a gurgling sound only when you draw off water from your kitchen sinks, understand that there is a problem with your vent.

The vent may not have been fitted appropriately from the P-trap, or it is obstructed. For 1.5-inch drainage pipe, the vent should be fitted at a distance of 3.5 feet from the bottom of the trap.

If this is not done, a vacuum that may result in gurgling is likely to be created. Alternatively, your drain may be built with an air admittance valve rather than a vent; which is normally located under the sink. Confirm the condition of this valve, as it may be trapped or immovable.

Since water runs at a low speed when there isn't sufficient air in the drainage pipe, remains can pile up, and cause obstructions inside the pipe. As a result, you may be required to clean the P-trap as frequent as possible to avoid blockages.

Solving all the venting problems may save you from the gurgling of your kitchen sink. The circulation of air inside and outside the pipes reinstates the expected flow of water, and thus cleanses wastes into the sewage.

Vents extended to the roof are exposed to external wastes from birds and plant leaves - clearing these vents may solve your gurgling issues. Unpredictably, waste cascade into the vent pipes and become stacked in at the joining points.

You can always clear them by flushing water through the vent opening. Significantly, draining such vents require a great pressure that will remove hidden garbage stacked inside. You may use a plumbing auger to solve this problem.

In this case, you will push the auger down the drain and force it deeper to the blockage. The auger will help you to push or pull the debris and create a space in the vents.

People normally experience blocked kitchen sink as a result of foreign particles entering the drain. Use a sink strainer to avert garbage and debris from blocking the drainpipe.

Every member of your family should apply some common sense when it comes disposal of food leftovers. You should dilute any soap you use for cleaning your kitchen sink to avoid blockage in the sink pipes.

It is advisable to use kitchen soap dispenser for cleaning purposes since it cannot clog in the drains and it removes all dirt. You will be required to flush your sink properly to force remains into the main sewage pipe.

You should allow water to run excessively for some minutes to make sure that all the remains are drained. This will thrust waste from the drainpipe into the main pipe that runs to the sewage.

What's Next?

In conclusion, you may experience gurgling sound as a result of family negligence or improper plumbing in your kitchen. Your family should not deposit food remains or oily substance in the sink as this may cause pillage inside the drain pipe.

On the other hand, you should choose expert plumbers to help you install drain pipes that will not cause gurgling during drainage. Gurgling sound can interrupt the peace you have with your family, and may cause ear problem. Finding a solution to this sound is solely on your hand.
