Why Is My Badger Garbage Disposal Leaking?

Garbage Disposal 8

Garbage disposals are a handy appliance in any kitchen, helping to eliminate food waste and keep your sink clean. However, like any appliance, they can develop problems over time. One of the most common issues is a leak, which can be frustrating and potentially damaging to your kitchen.

In this article, we will delve into the reasons why your Badger garbage disposal may be leaking and provide you with practical solutions to address this issue.


Your Badger garbage disposal might be leaking due to damaged or worn-out seals, cracks in the interior, or loose connections. You can troubleshoot by first identifying the source of the leak, then checking the sink flange, inspecting the drain lines, examining the bottom of the unit, and checking adjacent plumbing. If the issue persists, it may be time to replace your garbage disposal.

Recognizing a Leak

The first step in addressing a leak in your garbage disposal is to recognize that there’s a problem. Signs of a leak include a damp, soggy cabinet under your sink, a dripping sound when you run the disposal, or a rotten or spoiled food smell. If you notice any of these signs, it’s time to investigate further.

Common Causes of Leaks

Leaks in your Badger garbage disposal can occur due to several reasons:

1. Damaged or Worn-Out Seals

A busted seal inside the disposal can lead to leaks. This could be due to a faulty or disintegrating seal inside the top of the device, commonly known as the sink flange.

2. Cracks in the Interior

Leaks from the bottom of your disposal, particularly near the reset button, are usually attributed to cracks on the inside of the device. This can be due to basic wear and tear or corrosion over time.

3. Loose Connections

If your disposal is leaking from the side, it could be because of loose drain lines. There are two drain lines connected to your system, and if they are not properly tightened, they can cause leaks.

Troubleshooting a Leak

Once you’ve identified that your garbage disposal is leaking, the next step is to troubleshoot the issue. Here is a step-by-step guide:

1. Safety First

Always unplug the garbage disposal unit from the power source to avoid any accidents while working on it.

2. Identify the Leak Source

Place a bucket or a small garbage can underneath the sink to collect any leaking water. Turn on the water and fill up the sink a little less than half full. Observe where the water is leaking from.

3. Check the Sink Flange

If the leak is coming from the top of the disposal, it may be due to a loose sink flange. Tighten the mounting bolts and ensure the plumber’s putty is not compromised. If necessary, reseal it with fresh putty.

4. Inspect the Drain Lines

If the leak is coming from the side, it could be due to loose drain lines. Tighten the connections and check for any cracks or damage in the pipes.

5. Examine the Bottom of the Unit

If the leak is coming from the bottom of the garbage disposal, it could be due to a damaged or worn-out seal. In this case, you may need to replace the seal or the entire unit.

6. Check Adjacent Plumbing

If the leak is coming from adjacent plumbing, tighten the joints as needed. If you need help, consider contacting a certified plumber.

7. Test the Unit

After addressing the potential issues, plug the garbage disposal back in and run water through it to check if the leak has been resolved.

Tools You’ll Need

To fix a leaking Badger garbage disposal, you’ll need some basic tools, including a wrench, screwdriver, plumber’s putty, and possibly a hacksaw and pliers.

Preventing Future Leaks

Prevention is always better than cure. By maintaining your garbage disposal properly, you can prevent future leaks. Run the disposal regularly, inspect seals and gaskets for wear and tear, clean the disposal regularly, and avoid putting inappropriate items in the disposal.

When to Replace Your Garbage Disposal

Sometimes, it might be more cost-effective to replace your garbage disposal rather than repair it. If your garbage disposal is making unusual noises, constantly clogging, requiring frequent resets, draining slowly, emitting persistent odors, leaking water, or not functioning at all, it’s time to consider replacing it.

In conclusion, while a leaking garbage disposal can be frustrating, it’s often a problem that can be easily addressed. By understanding the potential causes of a leak and following these troubleshooting steps, you can quickly resolve the issue and get your kitchen back to normal. However, if you’re ever in doubt, don’t hesitate to call a professional plumber for help.
