How to Fix a Bathroom Sink that Won't Drain

What Is a Sink Drain?

A sink drain is a hole in the sink that allows water to drain out. The Drain cover is placed over this hole to keep things from falling in and to prevent evaporation. Most sinks will also have a pop-up drain stopper to plug the sink when needed.

The P-trap is a pipe that is located under the sink and is connected to the drain pipe. This pipe holds water to prevent sewer gases from entering the home through the drain. The tailpiece is the vertical pipe that connects the P-trap to the drainpipe.

A sink has many parts that work together to help it function properly. The drain flange is the part of the drain that is visible at the top of the sink and helps to ensure that the sink works properly for years to come.

What Are the Possible Causes of A Bathroom Sink Not Draining?

A clogged bathroom sink is a common household problem. Several possible causes of a sink not draining include a build-up of soap scum, hair, or grease.

Another possibility is that an object, such as a toy or small piece of jewelry, has fallen into the drain and is blocking the flow of water. Sometimes, the problem may be caused by a faulty P-trap or drainpipe.

6 Ways to Follow How to Fix a Bathroom Sink that Won’t Drain

If your bathroom sink is draining slowly or not, the problem may be a clog in the drainpipe. Here are a few ways to clear the clog and get your sink draining properly again:

1. Use a Plunger

The first step is to use a plunger. You can purchase one at a hardware store if you don’t have one. Put the plunger over the drain and pump it up and down. This will create suction that will help to dislodge the clog.

2. Use Boiling Water

If the above method doesn’t work, you can try using boiling water. Boil a pot of water and carefully pour it down the drain. Be sure to do this slowly, so the boiling water doesn’t splash back up at you. Doing this should help to break up any clogs in your drain. You can also pour a pot of boiling water down your drain once a week as a preventative measure to keep clogs from forming.

3. Use a Wire Hanger

If your drain is clogged and you don’t have a plunger, you can try using a wire hanger. Unbend the wire hanger so you have a long, thin piece of metal. Carefully insert this into the drain and wiggle it around to try and dislodge the clog.

4. Use a Drain Snake

If there’s still water draining slowly through your bathroom sink, it’s probably due to a clog further down the drainpipe. You can try to break up the clog using a drain snake, also called a plumber’s auger. First, remove the stopper from the sink and insert the drain snake into the drain.

Turn the handle on the drain snake to rotate the auger and break up the clog. Be careful not to scratch your sink with the auger. You may need to call a plumber if you can’t clear the clog with a drain snake.

5. Use Chemical Drain Cleaners

If standing water is in your bathroom sink, you can use a chemical drain cleaner to remove the clog. Chemical drain cleaners are available in most hardware stores and can be used according to the instructions on the package. Be sure to wear gloves and eye protection when using these products.

6. Call a Plumber

If you’ve tried all of the above methods and your bathroom sink is still draining slowly or not at all, then you may need to call a plumber. A plumber can use a power auger to clear out serious clogs located further down the drainpipe. If you have a warranty on your sink, you may be able to get the plumber’s visit covered.

That’s it! You’ve now learned how to fix a bathroom sink that won’t drain. By following these simple steps, you can clear most clogs and get your sink draining properly again. If the problem persists, be sure to call a professional plumber for assistance.

How Can I Prevent My Bathroom Sink from Becoming Clogged?

Clogged bathroom sinks are a common household problem. While many commercial drain cleaners are available, they can be expensive and contain harsh chemicals. Luckily, you can do a few simple things to keep your sink flowing freely.

First, be sure to dispose of all waste properly. Avoid putting coffee grounds, eggshells, or grease down the drain. These items can build up over time and create clogs. Second, use a strainer in your sink to catch debris before it has a chance to go down the drain.

Finally, run hot water through your drain regularly to help keep it clear. By following these simple tips, you can prevent your bathroom sink from becoming clogged.

Why Did My Bathroom Sink Start Leaking After I Unclogged It?

If your bathroom sink starts leaking after you unclog it, there could be a few different reasons why. It could be that the clog was only partially removed, and when you turned the water back on, the remaining debris caused the leak. It’s also possible that there is damage to the pipes or fixtures that weren’t apparent until you removed the clog.

Unclogging a sink can sometimes increase the pressure in the pipes, leading to leaks. If you’re not sure what the cause of your leak is, it’s best to call a plumber so they can take a look and make any necessary repairs.

What to Do if Your Bathroom Sink Smells Bad?

If your bathroom sink smells bad, there are a few things you can do to freshen it up. First, make sure to clean the drain regularly with a plunger or a plumber’s snake. This will remove any build-up of soap scum, hair, and other debris that can cause odors.

If the smell persists, you can try pouring baking soda down the drain and flushing it with hot water. You can also try using vinegar or bleach to kill any bacteria causing the odor. If all else fails, you may need to call a plumber to inspect the drain for any blockages or leaks. Keep reading for more information about how to fix a bathroom sink that won’t drain.
