What Can't Go Down the Garbage Disposal with a Septic Tank: A Comprehensive Guide

When you have a garbage disposal connected to a septic tank, it is crucial to be cautious about what you put down the disposal to ensure the health and longevity of your septic system. In this comprehensive guide, we will discuss what you should avoid and how to maintain a healthy and efficient septic tank system.

Common Mistakes and What to Avoid

1. Grease and Oils

Grease and oils are a common culprit in clogging septic tanks. When fats solidify in the tank, they can cause blockages that disrupt the system's operation. To avoid this issue, it is best to throw these items in the trash instead of disposing of them through the disposal.

2. Fibrous Foods

Items like celery, corn husks, and artichokes should be avoided as they can tangle and cause blockages in the pipes. These materials can form a mat that can clog the septic system and cause problems over time.

3. Starchy Foods

Items such as potatoes, rice, and pasta can expand in the septic tank and create sludge. These foods can disrupt the natural balance of the tank and cause the buildup of hazardous substances that can lead to malfunctions.

4. Coffee Grounds

Coffee grounds can accumulate over time and form a clog in the septic tank. It is best to dispose of these grounds in the trash to prevent them from causing persistent blockages.

5. Eggshells

Eggshells are sometimes believed to help in grinding the disposal, but they can also contribute to sludge buildup. It is best to avoid them and dispose of them in the trash.

6. Meat and Bones

Meat and bones can be particularly harsh on the disposal unit and may not break down properly in the septic system. These items should be disposed of in the trash to prevent major issues.

7. Non-Food Items

Plastic, glass, metal, and any other non-biodegradable materials should never be put in the garbage disposal. These items can cause severe blockages and damage to the septic tank.

Chemical Substances: A No-Go Area

Using harsh chemicals in the garbage disposal can disrupt the beneficial bacteria in the septic tank. Bleach, detergents, and other chemicals can destroy the delicate balance of bacteria needed for proper function. This is also why waste from washing machines needs a separate drainage system; chlorine-based products can severely harm the tank's health.

Maintaining a Healthy Septic System

To maintain a healthy septic tank system, it is essential to limit the use of the garbage disposal and dispose of solid waste in the trash whenever possible. Regular maintenance of your septic system is also crucial. This includes checking the system for leaks, pumping it when necessary, and having it inspected by a professional on a regular basis.

By following these guidelines and being mindful of what goes down the disposal, you can ensure that your septic tank remains functional and efficient, contributing to the overall health of your home and environment.
