A gurgling drain may seem like a minor nuisance, but it can actually be a sign of a larger issue lurking in your plumbing system. When you hear that unsettling sound coming from your sink, shower, or toilet, it typically indicates an air or drainage issue. Left unchecked, a simple gurgling drain could lead to slow drains, clogs, or even more serious plumbing problems down the road.

In this blog, we’ll walk you through some simple DIY solutions you can try to fix a gurgling drain. But we’ll also explain when it’s best to call in a professional plumber to handle more complex issues. Plus, we’ll give you some tips for maintaining your plumbing to avoid the problem in the future.

What Causes a Gurgling Drain?

Before diving into solutions, it’s important to understand what’s causing the gurgling in the first place. In most cases, it’s one of the following issues:

Clogs or Blockages

A partial clog can slow the water flow down, preventing it from draining properly. This causes the water to move more slowly, which can create a gurgling sound as it forces air to escape from the pipe. Common blockages include hair, soap scum, grease, food particles, or mineral buildup.

Air Trapped in the Pipes

A gurgling sound often happens when air gets trapped in the pipes, causing bubbles to form as water flows through. This is most common in drains that are partially clogged, where air pockets are unable to escape efficiently.

Ventilation Issues

Every plumbing system needs proper venting to prevent air pressure imbalances in the pipes. If the vent stack is blocked or clogged, it can cause air to become trapped in the system, leading to the familiar gurgling noise.

Plumbing Design Flaws

In some cases, the problem may lie with the design of your plumbing system. Poor pipe slope or improper venting can result in slow drainage, leading to gurgling and potential flooding. If you have an older system, this may be more likely.

By identifying the root cause of the gurgling, you’ll know whether it’s something you can fix yourself or whether you’ll need professional help.

Simple DIY Solutions to Try

If your drain is gurgling but not completely clogged, you can often solve the problem with a few simple DIY fixes. Here’s a step-by-step guide to help you get started:

1. Plunge the Drain

Start with a plunger, which can often help solve the issue. When using a plunger, make sure it creates a proper seal around the drain and that there’s enough water to submerge the rubber part of the plunger. Then, plunge vigorously for about 30 seconds. The suction created by the plunger helps break through minor blockages, allowing water to flow freely and air to escape the pipes. This method is effective for most gurgling drains, but if it doesn’t work, try repeating the process.

2. Clean the Trap

If plunging doesn’t resolve the issue, it may be time to clean the trap. The P-trap, or U-bend, located under the sink, often catches debris that can lead to gurgling. Turn off the water supply and place a bucket underneath the trap to catch any water. Using a wrench, loosen the slip nuts on both sides of the trap and remove it. Check for any blockages and clean out the debris. After cleaning, reassemble the trap, tightening the slip nuts, and test the drain by turning the water back on.

3. Use a Drain Snake

Another tool to consider is a drain snake. A drain snake, or auger, can reach deeper blockages that a plunger can’t handle. To use the snake, insert it into the drain opening and begin turning the handle to work the snake deeper into the pipe. When you encounter resistance, continue turning to break through the clog. Once the blockage is cleared, slowly pull the snake out while continuing to rotate it. Afterward, flush the drain with hot water to ensure that any remaining debris is washed away.

4. Baking Soda and Vinegar

For lighter blockages or buildup, try using baking soda and vinegar as a natural solution. This eco-friendly alternative is gentle on your pipes and effective at removing minor clogs. Pour 1/2 cup of baking soda into the drain, followed by 1/2 cup of vinegar. Cover the drain to keep the reaction contained and let the mixture sit for 30 minutes. The fizzing action helps break down the clog. After waiting, flush the drain with hot water. For persistent blockages, you can repeat this method or follow it up with a drain snake.

When to Call a Professional Plumber

While DIY methods are often effective for minor issues, there are times when you need to call in a professional plumber. Here are a few situations when it’s best to leave the work to the experts:

If your drain continues to gurgle after trying DIY fixes or if it becomes completely blocked, it’s a sign that there may be a serious clog further down the line. Professional plumbers have the tools and expertise to clear more stubborn blockages. They may use methods like hydro jetting to clear pipes and prevent recurring issues.

Another situation where a plumber is necessary is if your vent stack is blocked. Ventilation is essential for keeping air pressure in balance within your plumbing system. If the vent becomes clogged, it can lead to gurgling drains and other issues. A plumber will be able to inspect the system and clear any blockages to restore proper ventilation.
Sometimes, the problem may be related to your pipes themselves. If your plumbing system is old, poorly installed, or has been damaged, the issue could require pipe replacement or re-piping. Professional plumbers can assess the situation and recommend solutions such as pipe repair, replacement, or re-routing to fix the problem and prevent future gurgling.

Why You Should Avoid Chemical Drain Cleaners

Chemical drain cleaners may seem like a quick and easy fix, but they can cause more harm than good. Here’s why you should avoid them:

The harsh chemicals in drain cleaners can corrode pipes over time, especially older ones. This weakens your plumbing and can lead to leaks or pipe bursts, causing significant damage to your home and potentially costing thousands in repairs.

Additionally, chemical drain cleaners are harmful to the environment. When these chemicals are flushed down the drain, they can pollute water sources, endangering local ecosystems and wildlife. There are eco-friendly and safer alternatives, such as the methods discussed above, that can effectively clear blockages without causing harm.
Chemical cleaners typically provide only a temporary solution. They may clear a clog for a short period, but they don’t address the underlying cause of the issue. Professional plumbing solutions ensure that the root problem is addressed, preventing recurring blockages and other plumbing problems down the line.

Pro Tips for Maintaining Healthy Drains

Prevention is key when it comes to avoiding gurgling drains. Here are some tips to keep your plumbing in top condition:

Installing drain strainers in your sinks and showers is one of the easiest ways to prevent debris, hair, and food particles from entering the pipes. Strainers catch these items before they go down the drain, reducing the likelihood of clogs and keeping your drains running smoothly.

Avoid pouring grease, oil, and fat down the drain. These substances can solidify in your pipes, leading to blockages. Instead, dispose of grease by pouring it into a container and throwing it in the trash.

Regularly schedule plumbing inspections with a professional. A plumber can catch potential problems early, such as worn-out pipes, leaks, or minor clogs, before they develop into more significant issues. A yearly inspection can save you money and hassle in the long run.
