Clogged Sink from Coffee Grounds? Here’s How to Fix It

Have you ever wondered, “Can coffee grinds go down the sink?” The short answer is no. Coffee grounds can clog drains and create stubborn blockages. At John Padilla Plumbing, San Diego’s trusted drain professionals, we’ve seen it all—from minor clogs to major plumbing disasters caused by coffee grounds in sinks and garbage disposals.

Why Coffee Grounds Clog Drains

Many homeowners mistakenly believe that coffee grounds will break down in water. However, do coffee grounds clog drains? Absolutely. Here’s why:

• Coffee grounds do not dissolve in water, unlike instant coffee.

• They clump together, forming dense, sticky blockages.

• Over time, they bind with grease and debris, worsening the clog.

• A build-up of coffee grounds in the sink can lead to costly repairs.

How to Dissolve Coffee Grounds in Drain Pipes

If you’ve accidentally washed coffee grounds down the sink, act fast! Here are effective ways to clear the clog:

1. Hot Water Flush

Pour boiling water down the drain to loosen small buildups. This can help if you only have a minor issue, but it won’t always work for severe clogs.

2. Baking Soda & Vinegar Solution

• Pour ½ cup of baking soda down the drain.

• Follow with ½ cup of vinegar and let it fizz for 30–60 minutes.

• Rinse with hot water to help break down the blockage.

3. Plunger Technique

If water is backing up, try using a plunger to dislodge the clog. If the problem persists, professional intervention may be needed.

4. Drain Snake or Auger

For tougher blockages, a drain snake can physically remove the coffee grounds from your plumbing system.
