What NOT to Put in Your Garbage Disposal with a Septic Tank: A Comprehensive Guide
Having a garbage disposal can be incredibly convenient, but when you also have a septic system, things get a little trickier. Improper disposal can lead to costly clogs, backups, and expensive septic tank repairs. This guide will cover exactly what shouldn't go down the drain if you're relying on a septic system, along with explanations to help you understand why.
Understanding the Septic System and Garbage Disposal Interaction:
Your garbage disposal grinds food waste into smaller particles, but these particles still end up in your septic tank. A septic system relies on bacteria to break down organic waste. Certain materials can overwhelm or kill these beneficial bacteria, leading to system failure. This is why careful consideration of what you put down your garbage disposal is crucial for maintaining a healthy septic system.
Foods to Avoid Putting Down the Garbage Disposal with a Septic Tank:
1. Fats, Oils, and Grease (FOG): This is the number one culprit for septic system problems. FOG solidifies as it cools, coating the pipes and creating clogs. It also interferes with the bacteria's ability to decompose waste, leading to sludge buildup and potential failure. Always pour cooled fats, oils, and grease into a container and dispose of them in the trash.
2. Fibrous Foods: Foods like celery, onion skins, artichoke hearts, and corn husks are notorious for clogging garbage disposals and septic systems. Even though they're ground up, they can still clump together and create blockages in your pipes. These should be composted or disposed of in the trash.
3. Starchy Foods: Large quantities of starchy foods like potatoes, pasta, and rice can create a thick sludge in your septic tank, overwhelming the bacteria and reducing its effectiveness. Use moderation when disposing of small quantities of these foods.
4. Coffee Grounds: While often touted as being okay, coffee grounds can bind together with other waste in your septic tank, contributing to clogs and reduced efficiency. It’s best to compost them instead.
5. Eggshells: Although they might seem harmless, eggshells can be abrasive and contribute to wear and tear on your disposal and pipes. Furthermore, large quantities can contribute to clogging.
6. Bones: Even small bones are too hard for most garbage disposals to effectively grind, leading to blockages.
7. Fruit Pits and Seeds: While small pits might pass through, larger pits and seeds can clog your pipes.
Other Items to Keep Out of the Garbage Disposal (Septic or Not):
1. Non-food Items: This includes plastics, rubber, glass, metal, and anything that isn't organic. These items can damage your garbage disposal and septic system.
2. Excessive Amounts of Food: Even if the food is appropriate for disposal, overloading your system with large quantities can still cause problems.
3. Chemicals: Cleaning products, paints, and other chemicals can harm the beneficial bacteria in your septic system.
4. Medication: Never flush or dispose of medications down the drain. Dispose of them properly according to local guidelines.
Frequently Asked Questions:
Q: Can I put vegetable scraps down my garbage disposal with a septic system?
A: Small quantities of soft vegetable scraps are generally okay, but avoid fibrous vegetables. Use your judgment and don't overload the system.
Q: What if I accidentally put something inappropriate down the garbage disposal?
A: If you suspect a clog, immediately turn off your garbage disposal and contact a plumber specializing in septic systems. Don't try to force anything through.
Q: How often should I pump my septic tank?
A: The frequency of septic tank pumping depends on factors like household size and water usage. Consult a septic system professional for recommendations.
Q: Are there any alternatives to garbage disposals for septic systems?
A: Yes, composting is a great alternative. You can also carefully scrape food scraps into your outdoor compost bin.
By following these guidelines and understanding the limitations of your septic system, you can maintain a healthy and efficient system for many years to come. Remember, preventative measures are always better than costly repairs. Consult a professional if you have any questions or concerns.
