Reason to Unclog Coffee Grounds From Sink:

Coffee grounds are great. They make the perfect cup of coffee, they’re super easy to dispose of, and they can even be composted! But one thing that people don’t talk about is what happens when there are too many coffee grounds in one place. It’s not pretty. When coffee grounds are in excess, they usually end up finding their way somewhere where you don’t want them to. If the water in your sink is draining slowly, it’s probably because there are too many coffee grounds in your pipes.

Steps on How To Unclog Coffee Grounds From Sink

So now that we know why this happens let’s get to business. In the following, I’ll outline how you can unclog coffee grounds from the sink.

Step 1: Throw Some Boiling Water Down The Drain

This is probably the easiest way to clear out your sink. Just pour about a cup of boiling water down the drain and let it sit for a few minutes before running the hot water. Repeat this process a few times until it’s running clear. For more serious clogs, you may have to do the boiling water trick a few times.

Step 2: Pour A Pot of Boiling Water Down Your Shower Drain

Every home has, on average, about two showers and one bathtub, meaning that there are three drains in your home. That’s a lot of surfaces for excess coffee grounds to accumulate on! If the water down your sink is running slow, then it might be worth checking out the drains in your shower and bathtub as well. You can pour a pot of boiling water down your shower drain just like you did with your kitchen sink.

Step 3: Pour Some Baking Soda Down The Drain

Pour about 1/2 a cup of baking soda down the drain and follow it with some vinegar. Let the mixture sit for about 30 minutes before running hot water. The chemical reaction between the baking soda and vinegar should do all the work in unclogging your drain! If there are still coffee grounds in the trap, then run some more boiling water.

Step 4: Clear Out the P-Trap Under Your Sink

If you’ve done all of these steps and your sink is still clogged, there’s a good chance it’s because you missed one thing. Coffee grounds can often get stuck in a p-trap under any stubborn residue still in the drain. Try re-applying for some baking soda and vinegar.

Step 5: Try A Dish Soap and A Plunger

Grab a dish soap and pour it down the drain, followed by a cup of boiling water. After that, grab your plunger and plunge about 10 – 15 times until all the water has drained. This hot water and dish soap combination should break up the clog, allowing you to flush it all down with boiling water.

Step 6: Steps Instructions: Call Your Plumber!

If all these tips still don’t work, call your plumber because something is seriously wrong with your drain. I use Stephen West Plumbing because they know how to unclog coffee grounds from sink, and they do it fast.

The best way to get rid of coffee grounds in the sink is by using a plunger. This will create suction that can pull all ground particles into it, leaving your pipes clean and clog-free! If you don’t have one on hand or need an extra pair of hands for this tricky task, enlist someone else to help out while you hold onto the handle at the top of the plunger. Make sure they position themselves, so their arms are wrapped around yours with their palms facing up over your hands, holding down on either side.

Once they’re ready, tighten your grip and start pumping vigorously until all coffee grounds disappear. Afterward, rinse thoroughly with hot water before rinsing again with cold water.
