Common signs of a clogged drain

Slow draining water

One of the most common signs of a clogged drain is water that drains slowly. When you notice that the water in your sink, bathtub, or shower is taking longer than usual to drain, it could indicate a buildup of debris or an obstruction in the pipes. This can be frustrating and inconvenient, but fortunately, there are ways to troubleshoot and address the issue.

Water backups

Another sign of a clogged drain is water backups. If you notice that water is backing up in your sink, shower, or toilet and doesn’t drain properly, it is a clear indication that there is a blockage in the pipes. This backup can cause water to overflow onto the floor, potentially leading to water damage and other problems if not addressed promptly.

Unpleasant odor

A clogged drain can often emit a foul odor that is hard to ignore. The blockage in the pipes can trap food particles, hair, grease, and other debris, creating a breeding ground for bacteria and unpleasant smells. If you detect a lingering odor coming from your drains, it is a sign that there may be a clog that needs attention.

Tools and materials you will need

When troubleshooting a clogged drain, it is helpful to have a few basic tools and materials on hand. Here are some essential items you may need:

A plunger is a versatile tool that can be used to clear many types of clogs. It consists of a rubber cup attached to a handle and creates suction to dislodge and remove obstructions in the pipes. Having a plunger in your home is beneficial for dealing with minor clogs in sinks, toilets, and showers.

Plumbing snake or auger

A plumbing snake or auger is a long, flexible tool that is used to break up and remove stubborn clogs. It features a coiled wire or cable and a rotating handle that allows you to maneuver the snake deep into the drain and hook onto the blockage. This tool is particularly useful for dealing with more severe clogs or those located further down the pipe.

Baking soda and vinegar

Baking soda and vinegar are natural cleaning agents that can help dissolve minor clogs and eliminate odors. When combined, these household items create a chemical reaction that can break down debris and clear the drain. Having baking soda and vinegar on hand can be a cost-effective and eco-friendly solution for maintaining a healthy drain system.

How Do You Troubleshoot A Clogged Drain?

Methods to troubleshoot a clogged drain

When faced with a clogged drain, there are several methods you can try to resolve the issue. The appropriate method will depend on the severity of the clog and the location of the obstruction. Here are three common methods to troubleshoot a clogged drain:

Using a plunger

A plunger is a simple yet effective tool that can help you remove many types of clogs. To use a plunger, follow these steps:

Choose the right plunger

There are different types of plungers available, and choosing the right one can help you achieve better results. For sinks and showers, opt for a flat-bottomed plunger, while for toilets, use a flanged plunger with an extension that fits inside the drain hole.

Create a seal over the drain

Ensure that you have a good seal over the drain by covering it completely with the rubber cup of the plunger. This will help create the necessary suction to dislodge the clog.

Apply pressure with repetitive plunging

With the plunger firmly sealed over the drain, push down and then pull up on the handle in a repetitive motion. This vacuum-like action will help loosen the clog and allow it to be flushed away. Continue plunging until the water starts to drain freely.

Clearing the P-trap

The P-trap is a curved section of pipe located beneath sinks and other fixtures. It is designed to prevent unpleasant odors from entering your home while still allowing the waste to flow through. To clear a clog in the P-trap, follow these steps:

Locate the P-trap

Underneath your sink, you will find a curved pipe known as the P-trap. This pipe is usually shaped like the letter “P” or “U” and connects to the main drain pipe. Place a bucket or container under the P-trap to catch any water that may spill out.

Place a bucket under the P-trap

Before removing the P-trap, it is essential to have a bucket or container ready to catch any wastewater or debris that may come out. This step will help prevent any mess or further damage.

Remove and clean the P-trap

Gently remove the P-trap by unscrewing the slip nuts or compression fittings on each end. Carefully clean out any debris or clogs that may be present inside the trap using a brush or running water. Once clean, reattach the P-trap by tightening the slip nuts or compression fittings.

Using a plumbing snake or auger

If the clog is particularly stubborn or located further down the drain pipe, a plumbing snake or auger can be an effective solution. To use a plumbing snake or auger, follow these steps:

Insert the snake into the drain

Insert the head or tip of the plumbing snake into the drain opening and start feeding it into the pipe. Slowly rotate the handle clockwise to help guide the snake through the bends and curves of the pipe.

Turn the handle and push the snake further

As you feel resistance, turn the handle of the plumbing snake to break up the clog and push it further down the drain. Continue feeding the snake until you have reached the obstruction.

Remove the snake and check for debris

Once the snake has reached the clog, carefully pull it back out of the drain. Check the tip for any debris or obstructions that may have been dislodged. Dispose of any debris and run water down the drain to ensure it is clear.

Preventive measures to avoid clogged drains

Preventing clogged drains is easier than dealing with them. By taking a few preventive measures, you can minimize the risk of experiencing a drain blockage. Here are some tips to help you avoid clogged drains:

Install drain covers

Investing in drain covers for your sinks, showers, and tubs is an excellent way to prevent debris from entering the drain. These covers catch hair, soap residue, and large particles, preventing them from causing clogs in the pipes.

Avoid pouring grease or oil down the drain

Grease and oil may seem harmless when in liquid form, but they can quickly solidify and cause clogs in your drains. Instead of pouring grease or oil down the drain, dispose of them in a sealable container and throw them in the trash.

Regularly clean the drain

Regularly cleaning your drains can help prevent the buildup of debris and reduce the risk of clogs. Use a mixture of baking soda and vinegar or warm soapy water to flush your drains and remove any residue. Additionally, flushing drains with boiling water can help dissolve small clogs and keep the pipes clear.

When to call a professional plumber

While many clogs can be resolved with DIY methods, there are instances when it is best to call a professional plumber. Here are three situations where you should seek professional help:

Persistent clogs that won’t clear

If you have tried various methods and tools but the clog persists, it may be a sign of a more serious problem deeper within the plumbing system. A professional plumber will have the expertise and specialized equipment to diagnose and resolve the issue effectively.

Multiple clogged drains in the house

If you are experiencing multiple clogged drains throughout your home simultaneously, it could indicate a more significant issue with your plumbing system. This could be due to a clog in the main drain line or a problem with the sewer line. Consulting a professional plumber is crucial in such cases to prevent further damage.

Old plumbing system

If you have an older home with an aging plumbing system, clogs may be a common occurrence. Older pipes are more prone to corrosion, buildup, and collapse. To ensure the long-term health of your plumbing system, it is advisable to have a professional plumber inspect and address any issues with your pipes.

Additional tips and tricks

Here are some additional tips and tricks to help you troubleshoot clogged drains:

Use baking soda and vinegar to unclog drains

As mentioned earlier, a mixture of baking soda and vinegar can be an effective DIY solution for minor clogs. Pour a cup of baking soda down the drain, followed by a cup of vinegar. Allow the mixture to fizz and work its way through the pipes for about 30 minutes before flushing with hot water.

Flush drains with boiling water

Regularly flushing your drains with boiling water can help dissolve small clogs and keep the pipes clear. Boil a kettle of water and carefully pour it down the drain. Repeat this process once a week to maintain a healthy drain system.

Regular maintenance

Performing regular maintenance on your drains can help prevent clogs and identify any issues before they become major problems. Use a drain strainer to catch debris, avoid flushing inappropriate items down the toilet, and periodically check for signs of slow drainage or odors.


Dealing with a clogged drain can be a frustrating experience, but with the right tools and methods, you can effectively troubleshoot and resolve the issue. Whether you choose to use a plunger, clear the P-trap, or utilize a plumbing snake, following the proper steps will help you restore the free flow of water in your drains. Remember to take preventive measures to avoid future clogs, such as installing drain covers and avoiding pouring grease or oil down the drain. If persistent clogs occur, multiple drains are affected, or you have an older plumbing system, it is advisable to seek the help of a professional plumber. By following these tips and tricks, you can keep your drains clear and maintain a healthy plumbing system in your home.
