Possible Reasons For Smelly Drains In Bathroom

There are several possible reasons for smelly drains in the bathroom:

Clogged

Clogs in a bathroom drain can create a smelly drain for several reasons. When water is unable to flow freely through the drain, it can create standing water that becomes stagnant. This standing water can create a breeding ground for bacteria, which can produce a foul odor. 

Additionally, if the clog is caused by organic material like hair or soap scum, it can begin to decompose and create an unpleasant odor. Finally, if the clog is located near the vent pipe on the roof, it can prevent proper ventilation, which can cause odors to build up and become more noticeable.

Infested

There are several types of infestations that can cause smelly drains in a bathroom. One common culprit is a buildup of bacteria and other microorganisms. These can grow and multiply in standing water, creating an unpleasant odor. 

Another possible infestation is a buildup of organic material like hair or soap scum, which can begin to decompose and create an odor. In some cases, pests like cockroaches or rodents can also be the source of a smelly drain. These pests can crawl into the drain and get stuck, causing an odor as they decompose.

Dry

A dry P-trap can make a bathroom drain smelly because it allows sewer gases to escape into the room. The P-trap is a plumbing fixture that is designed to prevent sewer gases from entering a building. It is called a P-trap because it is shaped like a “P” and is filled with water at all times. 

This water forms a barrier that prevents sewer gases from escaping through the drains. However, if the P-trap becomes dry, either because the water has evaporated or because the drain has not been used in a while, the barrier is no longer present and sewer gases can escape into the room, creating a foul odor.

Pressure

High pressure in a bathroom drain can cause it to become smelly in several ways. One possible reason is that the increased pressure can cause water to flow more quickly through the drain, which can create a vacuum effect. This can cause air to be drawn into the drain through any cracks or gaps, bringing sewer gases with it. 

Another possible reason is that the increased pressure can cause the water in the P-trap to be pushed out, allowing sewer gases to escape. In some cases, high pressure can also cause pipes to vibrate or make noise, which can be unpleasant and cause the drain to seem smelly.

🟦 Clean the drain

To remove drain clogs in a bathroom, you can try using a plunger to push the clog through the drain. If that doesn’t work, you can make a cleaning solution by mixing equal parts baking soda and vinegar. Pour the mixture down the drain and let it sit for a few hours before flushing the drain with hot water. You can also use a store-bought drain cleaner according to the instructions on the packaging. 

If the clog is still not cleared, you may need to use a plumbing snake, which is a long, flexible tool that can reach into the pipes and break up the clog. It’s important to never pour grease or oil down the drain, as this can cause clogs. Additionally, regularly cleaning your drain can help prevent clogs from forming in the first place.

🟦 Unclog the P-trap

To unclog a P-trap, you can try using a plunger to push the clog through the drain. If that doesn’t work, you can try using a plumbing snake, which is a long, flexible tool that can reach into the pipes and break up the clog. You can also try using a store-bought drain cleaner according to the instructions on the packaging. 

If none of these methods work, you may need to disassemble the P-trap and clean it out manually. To do this, turn off the water supply and place a bucket underneath the P-trap to catch any water that may be in the pipes. Loosen the slip nuts on the P-trap and carefully remove it from the pipes. Clean out any debris that may be clogging the P-trap and reassemble it before turning the water back on. It’s important to never pour grease or oil down the drain, as this can cause clogs.

🟦 Clear the vent pipe

To clear a bathroom drain vent pipe, you will need to first locate the vent pipe. This is typically located on the roof of the building. Once you have located the vent pipe, you can try using a plumber’s snake or a wire hanger to clear any blockages.

🟦 Use a deodorizer

You can use a drain deodorizer to neutralize any bad smells and prevent them from returning. There are several deodorizers that can help remove a smelly drain in a bathroom. 

One option is to use a natural deodorizer like baking soda and vinegar. Simply mix equal parts baking soda and vinegar, and pour the mixture down the drain. Let it sit for a few hours before flushing the drain with hot water. 

Another option is to use a commercial drain cleaner, which can help break up any clogs and eliminate odors. These products are typically available at your local hardware store.

How To Prevent Bathroom Drains From Being Smelly?

📍 Regularly clean the drain

Use a mixture of baking soda and vinegar to flush out the drain and remove any buildup of grime or hair. This will help to eliminate any odors coming from the drain.

📍 Use a stopper or drain cover

This will prevent any debris or foreign objects from entering the drain and causing a blockage.

📍 Run hot water down the drain

This will help to break up any grease or soap scum that may be clogging the drain and causing a bad smell.

📍 Use a commercial drain cleaner

These products are specifically designed to remove clogs and eliminate odors from drains. However, be sure to follow the instructions carefully, as some drain cleaners can be harsh and damage the pipes if used improperly.

📍 Check for leaks

If the drain is leaking, it may be allowing water to seep out and create a breeding ground for bacteria, which can cause a bad smell. Fix any leaks as soon as possible to prevent this from happening.
