7 Common Reasons You Have a Slow Draining Sink


Common Reasons You Have a Slow Draining Sink

You’re doing the dishes, or you’re in the bathroom, washing your face. After about 5 minutes, the sink gets halfway filled up, and when you turn off the faucet, you watch the water slowly swirl and drain.

This is surely an annoyance. But not only that, it’s also a sign that there’s something wrong with your pipes.

Here are 7 common reasons why you have a slow draining sink and what some of the fixes are.

1. Chunks of Food Are Stuck

If the clog is happening in your kitchen sink, then you may have chunks of food stuck. This can be especially true if you don’t have a garbage disposal and people stack plates in your sink without clearing them off first.

Even if you’re super careful, you still may get a buildup of food over time. Yes, they’re biodegradable, but it may take a long time to deteriorate, which is what’s causing your clog.

Other things you need to watch out for are coffee grounds and eggshells. Those can build up in your P-trap, which can then cause your sink to drain slowly.

2. Silverware or Other Objects Are Stuck

It’s really easy to get silverware and other objects lost in the abyss of your kitchen sink. If water is quickly filling up your sink while you’re doing the dishes, then you might want to check that nothing’s obstructing the water flow.

As for your garbage disposal if you have one, quickly turn it on to see if it’s stuck on something. If it makes a loud whining noise, then you’ve definitely got a foreign object stuck there.

Make sure the garbage disposal is completely off and then reach in to try and find the thing that’s stuck. This should clear your clog quickly.

3. There’s a Buildup of Grease, Fat, and Oil

If you’ve been pouring the grease, fat, and oil from cooking down your drain, then you need to stop now.

Not only will these substances cause a backup in your kitchen sink, but once they get through, they’ll also clog sewer lines as well. If you and others are all washing grease, fat, and oil down your sinks, then it can turn into things called “fatbergs” in the sewers and cause dangerous backups.

It’s great that you now know you should stop doing this, but what should you do with the existing problem of a slow draining sink caused by these things?

Try combining boiling water with vinegar and baking soda, then flush your sink with it. You may need to do this several times to completely unclog your sink.

You can also use the above mixture whenever you accidentally get grease, fat, or oil down your sink. This can keep buildup from happening.

4. There’s Hair Stuck

In your bathroom, you probably shave your beard every so often and then wash your trimmings down the sink. Most hair should be short enough to get through your sink with no problem.

However, if you only shave periodically, this can cause an issue. This is because your hair’s longer and thicker, which can quickly clog your sink.

If possible, you should lay a paper towel across the sink, covering the hole. That way, it catches all your trimmings. Afterward, you can just pick it up and throw it into the trash, all without any of your trimmings going into the sink.

If you live with someone who has long hair and they do their hair in front of the bathroom sink mirror, the long strands may occasionally fall into the sink and get washed into the drains. To prevent this from happening, try picking up the strands and throwing them out whenever you see them.

5. There’s a Buildup of Products

Over time, your shaving cream, toothpaste, phlegm, soap, and any other products you use and wash down the bathroom sink drain will eventually build up. You may notice this when your sink not only drains slowly, but has some black slime.

If you see this black slime, then you need to clean your drains. Use the same mixture from point #3 on this list to flush your drains. Another thing you can try is using a small plunger on the sink and then flushing it with hot water.

Sometimes, you may need a heavy-duty solution. Try an enzyme-based buildup remover to see if that helps.

6. Old Pipes Are Deteriorating

If none of the above seem to be the problem with your slow draining sink, and the solutions don’t work either, then you may have old pipes that are deteriorating.

Or you may have an issue with your main drain line. For example, there may be roots growing into it.

In either case, you’ll need to have a professional plumber come identify the issue then make the appropriate repairs. If needed, they can also perform new sewer line replacements and installations as well.

Get Your Slow Draining Sink Fixed Now

As you can see, a slow draining sink can be caused by a number of things. While you can try some quick DIY fixes, if it doesn’t seem to get better, then you need to call a professional plumber.

The longer you leave the clog, the higher the chances of it damaging your pipes. As a result, you’ll need to call a plumber anyway, but the repairs will take longer and will be more expensive.

So do yourself a favor if you’ve ran through the list and tried everything you could. Call an expert plumber and get the issue taken care of immediately!
