Why Is My Sink Gurgling?

25 August

You would not want the drainage system to break down, and while a gurgling sound does not immediately raise concerns, it is best not to ignore it.

It can be quite concerning if a strange gurgling sound comes from kitchen and bathroom drains whenever you use the shower or wash your hands in the sink. This can be accompanied by slower water movement, which is already indicative of a problem inside the pipelines.

Also, you might find that the water is not moving well, or there is a leakage underneath the sink. While the sound may not irritate you much, there could be more significant issues if this problem is not taken care of immediately.

And that is where we step in! We have curated this guide with all the possible reasons behind a gurgling sink. Read on carefully to find out which of the following matches your situation and then take care of it accordingly.

4 Reasons Behind A Gurgling Sink

There can be multiple reasons why the sink can be gurgling, and in this section, we will discuss them all in detail.

How To Install A Kitchen Sink Drain

1. Blocked Pipes

Vent pipes are always connected to plumbing systems and they let sewer gases leave the house. These usually go around the roof and then escape from there. But in case there is a blockage in any of these pipes, then the gas might return from the drain and back into your kitchen or bathroom.

This situation will not only create a gurgling sound but is extremely dangerous as well. Sewer gases are highly inflammable and can cause explosions if not taken care of immediately. We will recommend calling a plumber on an emergency basis if you get a foul sewer smell along with a gurgling sound from the sink.

2. Incorrect Installation Of Vent Pipes

If you hear gurgling sounds only from one drain, then that could be linked to the inappropriate installation of the sinks, which could have created a vacuum. So, make sure that the drain vents are installed properly by plumbers in the first place. Remember that if you have a standard 1.5-inch pipe, then the required vent needs to be fixed 3.5 feet above the base of your drain.

If that is not done correctly, then a vacuum gets created, leading to weird sounds. This needs to be fixed by professional plumbers, but you can do it in your own time.

3. Clogged Drains

One of the most common reasons for weird sounds from the drain is a clogged drain. A drain can get clogged due to multiple reasons like fat and grease build-up, stuck food items, or oil accumulation. These will not let the water or gas pass through easily, and the obstructed movement will create a gurgling sound.

If the problem is not treated, your sink will not clear out completely, or water will move very slowly down the drain. Sometimes, the wastewater can also return from the pipes leading to a malfunctioning sink.

To help solve this issue, cleaning solutions are available in local stores that would dissolve the dirt inside and dislodge anything stuck in the passages. However, if you plan to use it, remember to be very careful and read all the instructions for the proper administration of the chemical.

This is essential because if the cleaner is not used the right way, it will invariably damage and corrode the pipes. That would lead to bigger problems and more expenses, and you would not want to go down that road. So, if you haven’t used such cleaners before, we would suggest calling an experienced plumber to tackle the issue.

4. Broken P-Trap

The P-trap is the pipe that runs underneath the sink and is generally placed inside cabinets below. It is an essential part of the drainage system, as it keeps wastes and debris from affecting the flow of water. If the P-trap gets damaged or wears out over time, then it can cause large scale clogging.

Grease, food particles and oil stuck in the passage of water can create that annoying gurgling sound. But there is a way to take care of this issue at home without hiring professional help.

How To Replace The Drain Trap On A Sink

Clean the P-trap once in a while so that it remains unobstructed. For this, you will have to open up the P-trap and then use a thin wire to clean out the debris. You can also use a coat hanger wire, a thin stick or a nylon brush cleaner to take out the dirt and then a brush to thoroughly clean the insides.

Once you are satisfied with the result and the brush comes out clean, you can assemble everything and connect them back before closing the cabinet. But keep in mind that if the screws of the P-trap appeared stuck, then they might need to be replaced. In this case, call a professional plumber who will do the job for you.

Tips To Take Care Of Your Sink

If you have recently cleaned your sinks or drains, we will recommend pouring hot water once in a while to keep the passage clear. You can also mix some vinegar and lemon in the water to ensure that the food particles inside are broken down properly. This will ensure better durability of the pipelines and prevent sinks from gurgling.

Also, do not pour grease or oil directly into the sink as they can damage the interiors or promote clogging. Clean your utensils and crockery well with a sponge or cloth before washing them in the sink to keep the grease from entering the pipeline.

Fixing Your Noisy Sink

Now that you know about the causes of a gurgling sink, remember that the earlier you treat it, the less money it will require. And while there are cleaning solutions available easily in local stores, always check them well before purchasing so that the chemical does not do more damage to your pipelines.

They may offer a cheap solution but may cause you to spend hundreds of dollars on repairs or replacements. So, if you’re unsure about using them, immediately call up a local plumbing service and book an appointment at the earliest.
