Why Is My Garbage Disposal Leaking From the Bottom?

For many homeowners, running the garbage disposal is a crucial step in the post-dinner cleanup process. This powerful device efficiently pulverizes food remnants to help maintain a clean and sanitary kitchen environment. However, even the most reliable garbage disposals may spring a leak from time to time.

If your garbage disposal is leaking from the bottom, it’s important to consult a professional to get to the root of the issue. There are a number of reasons why this might occur, and only a trusted plumber will swiftly identify the source of the problem. To ensure you’re prepared for the visit, it’s a good idea to familiarize yourself with the most common answers to the question, Why is my garbage disposal leaking?”

Worn or Damaged Seals

One of the most common causes of a leaking garbage disposal is worn or damaged seals. The goal of these seals is to keep leakage at bay. Over time, your disposal’s internal seals may begin to wear out, which can cause liquids to leak out from the bottom. In most cases, the seals cannot be replaced. This means you’ll likely need to install a new garbage disposal.

Cracked Housing

All garbage disposals have an interior shell that serves to house all the parts of the device. Because of this, the shell is commonly known as housing. As the disposal ages, the interior shell becomes susceptible to cracking. A cracked shell permits water to seep out from the seams, which can cause your garbage disposal to leak from the bottom. If you’re wondering how to fix a leaking garbage disposal, you’ll want to contact a plumber as soon as possible to have them take a closer look at the cracked housing.

Loose or Improperly Installed Connections

In some cases, you might be able to trace back the damage to the initial installation. When installing a new garbage disposal, it’s imperative to ensure all the cords and wires are connected properly. If an error took place at any point during the installation process, it might have contributed to the leak you’re seeing now. Be sure to contact a reputable pro to rectify the issue in a timely manner. The expert might need to rewire the device to resolve the leak and to keep additional damage at bay.


With regular use, your garbage disposal will inevitably begin to show signs of wear and tear. One of the most common signs of an aging disposal is corrosion and rust. Corrosion gradually wears down the device, making it susceptible to leaks. If your garbage disposal is already exhibiting signs of significant rust and corrosion, it might be best to replace it completely. Be sure to consult a trained plumber to determine the ideal course of action.

Impeller or Blade Damage

Your garbage disposal’s impellers are the key components that enable it to do its job. These sharp blades are mounted on a spinning plate that is activated whenever you turn on the disposal. With centrifugal force, the spinning plate attracts food waste particles while the blades pulverize the particles. If these components become damaged in any way, you’ll need to contact a professional to have them repaired as soon as possible. This will allow you to continue using your garbage disposal again in a timely manner.

There are many reasons why your garbage disposal might leak from the bottom. Instead of worrying about getting to the root of the issue on your own, trust a skilled plumber to identify the cause of the problem for you.
