How to Unclog a Garbage Disposal

Garbage disposals provide us with a fast and convenient way to minimize the amount of food waste we throw away in garbage bins. However, these appliances can get clogged as a result of improper use, dull blades, grease buildup, and more. A clogged garbage disposal can create an unpleasant and unsanitary situation. If you’re dealing with a clogged garbage disposal and wondering how you can safely unclog the appliance, this article is for you. In this guide, our qualified plumbers at Mr. Rooter Plumbing explain the different techniques you can employ to clean out your garbage disposal.

Step 1: Shut Off the Power Switch and Unplug the Disposal

Always tu off the power to the disposal before attempting any physical work. You can do this by flipping the switch under the sink or tuing it off at the breaker box. Unplug the disposal from the outlet for added safety.

Step 2: Perform a Manual Checkup

Once the breaker is off, try to find out what’s causing the clog. Shine a flashlight down the disposal opening to see if you can spot any visible objects causing the clog. If you can spot any objects, use a pair of tongs to carefully remove them. Never reach your hand into the disposal.

Our Customers Reviews

Chahib Chakrome

Summit, NJ

The service provided was great, nothing to say about the work of the plumber. 5 stars to him. But the company charges felt way too much for the work. We would have liked to have the same plumber take care of other things in the house, but every time he check how much extra the company will charge for the job, the price just got too much. The plumber did an amazing job he selected a beautiful faucet to replace our old one. He did his best. But the company prices have no room for negotiation.

New Brunswick, NJ

We got very quick service, I think the plumber actually arrived in less than an hour! After reviewing what was happening, he gave us our options and performed the option we selected. This happened in the late afternoon or early evening. It was already dark and there was a lot of snow on the ground.

Steve Smith

Mountainside, NJ

I needed immediate, same day service in the early evening at my home. I went to the internet and looked up plumbing services that offered "24-hour, 7-day a week" availability. The first 3 places I called said that they could not get to me until the following day. Then I called Mr. Rooter. They were courteous and promptly got a technician to my house within an hour and a half. The technician, Lucas Kaufmann, was exceptional. The job was not easy, but he figured the problem out and got me all fixed up within an hour's time. Moving forward, I…

Despite what was quite obviously a busy day (day after Thanksgiving at 10pm) TJ came out and did not leave until the job was done! There were several setbacks, which at the late hour might have prompted him to leave- but he chose to stay and continue until the job was complete! I only have one bathroom so I was really hoping he could make it work, and he really did a wonderful job! So thankful for all of his help! I highly recommend TJ!

Union, NJ

This is my second time using Mr. Rooter and I have to say they are an excellent company of experienced professionals! The service techs were courteous, experienced and actually spent time trying to figure out the issue before proposing the solution. They were also patient and answered all my questions without rushing the work. I will be using them again.

Christie Murphy

Montgomery, NJ

TJ was amazing! 10/10 recommend this company. We were in an emergency state of panic with a burst pipe in the middle of a bad snowstorm. TJ came with knowledge, professionalism, kindness, and found the root of the problem within five minutes of being here. We will be using him again in the spring to fix an outdoor issue he found!

Alan Abraham

Clark, NJ

The technicians were friendly, professional and knowledgeable. The price was too high I believe, but the technicians had no control over that. The technicians took their time and did a great job. I would use them again and also recommend them.

Amy Swart

Berkeley Heights, NJ

Excellent service! Charles and Nicholas of Mr. Rooter arrived to my scheduled service a few minutes early, wore sanitary shoe coverings, and were extremely professional. They found the source of my leak quickly and fixed the issue. While they here, I requested an additional hydraulic heating inspection which they accommodated. They were very knowledgeable and provided helpful tips. I highly recommend this team and I will definitely call them for all future plumbing needs!!

JACKY Coppola

Wall Township, NJ

TJ came to my aid as the water pipe froze in my house. Although nothing could be done he gave me hints of what could be done my me which was very helpful. I found TJ very professional and caring about my situation. The best part of the very long night was the dogs adored him one wanted to accompany him to his next job. Thank you for employing such an amazing man. Plus today there is water running in the house. Thank you TJ and thank you Mr. Rooney plumbing for employing a man with helpful hints!!!!!

Step 3: Use a Hex Wrench or Wooden Handle Manually Tu the Disposal’s Blades

Most garbage disposals have a slot on the underside for inserting a hex wrench—this tool is usually provided with the unit. Insert the wrench and carefully tu it back and forth to try and break up the clog. Do not force it if you encounter resistance. If you don't have a hex wrench, carefully insert a sturdy wooden spoon handle into the disposal chamber and gently tu it back and forth to dislodge the clog.

Step 4: Plunge the Drain

This is a simple drain cleaning technique that you can employ to unclog a garbage disposal. Here’s how it works:

  • Fill the sink with enough water to cover the disposal opening.
  • Use a sink plunger specifically designed for garbage disposals.
  • Plunge forcefully several times to dislodge the clog.
  • Flush the drain with hot water.

Step 5: Remove And Clean The P-Trap

Sometimes the clog may be lodged in the P-trap, located under the sink. The P-trap is designed to trap debris and prevent sewer gases from entering your home. Place a bucket under the P-trap to catch any water that spills out, then carefully loosen the nuts holding the P-trap in place and empty its contents into the bucket. Clean the P-trap with hot soapy water and reinstall it.

Step 6: If All Else Fails, Call A Professional Plumbing Repair Service

If you've tried all these steps and the clog persists, it's time to call a professional plumbing service that specializes in drain cleaning or garbage disposal repair. Skilled plumbers have the expertise and tools to diagnose the problem and safely clear even stubbo clogs.
