There are a variety of different methods that you can use before you call a plumber. However, if your drain is blocked, it can be challenging to know the best way to clear it. There are many different options for clearing bathroom sink drains that all have their pros and cons.

The most important thing when attempting to deal with a clogged bathroom basin is to avoid damaging the pipes. This will cause further issues when trying to clear the blockage. This section discusses the different methods to clear a bathroom sink. The first step to removing a bathroom sink blockage is to ensure that the water isn’t coming from a pipe under the sink.

There are two separate ways you can accomplish this: try turning off both your hot and cold water at the main valve, or turn on your hot water and then go into another room and turn off the cold water. If there is still a leak, you will need to call a plumber as soon as possible, as it is essential to seek professional help if the problem persists.

What causes a bathroom sink to clog?

The main thing that causes a bathroom sink to become blocked is that you have a clog in your drain. The main things that cause a blockage are often:

  1. Soap scum
  2. Soap residue
  3. Blocked bathtub or shower drain
  4. Pests
  5. Hair
  6. Grease and oils

How to clear a bathroom sink blockage

There are three primary approaches that you can use to remove a bathroom sink clog. They are:

  • Cleaning the plumbing by pouring boiling water down the drain with a cup of baking soda
  • Pulling a drain line out
  • Using a hanger to clean the plumbing

Note: It is necessary to make sure that there isn’t a blockage inside the pipe itself.

The 7 different methods of clearing bathroom sinks

A bathroom sink clog can be a very frustrating and annoying situation. It often happens that we try everything possible to unclog the drain and it remains blocked. This will describe the most common methods for clearing a bathroom sink which you can try at home.

1. Pour hot water down the sink

The use of hot water systems like a hot water heater can be very effective in dislodging materials that have accumulated in your pipes. It will heat the pipe and dissolve any build-up, allowing them to run out through the drains. Similarly, you can boil water and pour it down the drain.

This will soften up food debris and hair that may clog your system or any material blocking the drain, which can then be flushed away with hot water. Hot water helps to loosen and dissolve soap residues, greases, and oils that accumulate in pipes, which usually clog them up.

So, you can pour some hot water down the sink and wait for a few minutes before trying again to unblock it. Keep in mind that this can also work for a blocked kitchen sink. However, if this does not work, you should try boiling some hot water first before pouring it down the sink because this might have more effect on loosening up any grease or fats inside the pipes before they harden again.

2. Chemicals

This involves pouring some kind of chemical down the drain then waiting for it to start working. The first of these is caustic soda or sulphuric acid, depending on the type of drain you have. This has to be poured down the pipe and left for a while. Explicitly speaking, before being flushed out using a pot of boiling water.

It’s also essential to wear protective clothing and gloves when using this method because the chemicals can cause chemical burns if they splash onto your skin or eyes. Household chemicals such as baking soda and vinegar can also help to dissolve grease from inside your pipe, which causes blockages.

Chemicals can be great for removing grease and grease stains from your sink pipes. However, if you have a blocked drain, they can damage your pipes and make the drain even more difficult to unclog. These chemicals can also affect your home’s plumbing and cause problems with your sewer system.

Try using a plunger instead of chemicals. This is what most professional plumbers use to clear a blocked drain. If the drain is blocked at the intake, use the plunger to unclog the sink. However, do not use a plunger to unclog the drain after the plunger has broken through the surface. The water in the drain may be contaminated with chemicals and could cause a health hazard.

3. Plunger

This method is the easiest method that you can try. All you need is a plunger and a plastic cup or bucket that has been made into a funnel. You will have to throw the funnel on the floor and then sit on the floor with the plunger behind you. You will have to push down as hard as you can with the plunger.

This will cause the water to swirl around inside the funnel. As a result, the water and chemicals will move the substances towards the hole at the back of the sink.

This is generally considered a very gentle method. It can be done faster than you can say, “Darn it, the sink is blocked!” Once the drain is clear, you can pour hot water into the pipe to re-inflate the seal and allow the water to go down the drain. If you don’t have a plunger, try using a plumber’s snake or a wire hanger.

Sometimes, a plumber will clean out a bathroom sink for you, but this is not a standard service and should only be done if you can’t get it done yourself. To clean your sink with a wire hanger, first, wrap the end of the wire hanger in Teflon tape. This will make it easier for you to remove any residue that it picks up.

4. Drain cleaning using a bucket

This is one of the simplest and commonly used methods to get blocked sinks and drains running again. To empty the sink, you will need to use a bucket. You will need to fill it with water and some sort of strong detergent. You can use regular household drain cleaners to clean the sink, such as dishwashing soap or dishwasher detergent.

This method does not harm the pipes, and you can save the water you used for cleaning the sink in case you need to use it again. While this method can be pretty effective and simple if done correctly, it is only suitable for emergencies. Do not use the drain cleaning method unless you have the experience and the right tools. Moreover, the drain must be clogged.

5. Using a snake

Snake bait can be used to clear a blocked drain. This is typically made of heavy-duty plastic and is attached to a snakehead. The main benefit of using a snake is that it is very flexible. This is important when trying to remove the blockage without damaging the pipes. These snake bait pliers are very strong and will make clearing a sink much more manageable.

If your sink is clogged, then putting your drain snake into the drain hole can help with many issues. This method will often make a lot of progress, but it does not work in all situations. The drain snake must always be kept at the correct pressure; otherwise, it could damage the pipes. Moreover, a drain snake can be used to drain the drain when all else fails.

6. Feeding a wire down the drain

This method is probably one of the most commonly used to clear a blocked drain. You simply feed the drain with a different type of wire down the pipe and then begin gently removing the dirt. This usually does not cause much damage as you are using less force to do so. However, it will slow down the drain. To be safe, put a bucket underneath the sink or on the ground.

You will have to leave it for a few hours before attempting to reenter your bathroom. This can be the best way to clear a sink. This method of clearing a sink has been described to be the fastest. It is used by a lot of people, especially in a dorm room. However, you run the risk of damaging your pipes. It is a quick fix for a problem, but not the best.

7. Sewer stripping

Sewer stripping is perhaps the most well-known of the various ways to clean a bathroom sink drain. Moreover, it’s also one of the most popular methods. Here is how it works. You will need to go to a home improvement store and purchase some dry drain stripping.

Final thoughts

In a nutshell, the key to clearing a bathroom sink is to create a slow-running sink. A slow-running sink will allow a slow, steady flow of water into the drain. If a slow sink is not present, the blockage will not allow the water to move fast enough.

As a result, you will simply clear the sink of any waste blocking the pipe and let it run. Additionally, there are different ways, such as the ones mentioned above, to remove debris and prevent blockages in your pipes. However, these methods are dependent on several other factors that will need to be taken into consideration.

Christopher Chow

I called Hero Plumbing to unblock a shower drain and was unable to get a quote over the phone, but Sam the owner was here same day. After his first try, he made quick work of the blockage. I opted to also get the acid cleaner stuff poured down. Sam had run out, but made a trip to go pick some up to finish the job. If you opt for this treatment make sure you can easily air the bathroom as it’s extremely strong and produces a lot of fumes. Great Service and Honest Pricing.

I knew Sam when he was working alone. And from the first time I was pleasantly surprised by his work. A little later I found out that he has his own business. I am very happy about that. And I am very glad for myself that I have such a company that I can always rely on.

Thank you for your work. People need you very much.
