Frequently Asked Questions about Garbage Disposals for Septic Systems
Choosing the right garbage disposal for a septic system comes with its own set of considerations. Here are some common questions answered to help you make an informed decision.
Q1: Can I really use a garbage disposal if I have a septic system?
A1: Yes, you absolutely can! However, it’s crucial to choose a model specifically designed or recommended for septic systems. These disposals often grind food waste into much finer particles and some even include enzyme-based treatments to help break down solids, reducing the load on your septic tank.
Q2: What makes a garbage disposal “septic-safe”?
A2: A septic-safe garbage disposal typically has two main features:
1. Superior Grinding Power: It grinds food scraps into much smaller, more uniform particles than standard disposals. This prevents large chunks of food from entering the septic tank, which can lead to clogs and imbalance.
2. Enzyme or Bio-Charge System: Many top models (like the InSinkErator Evolution Septic Guard) come with an integrated system that injects beneficial enzymes or microorganisms into the grind chamber. These help accelerate the decomposition of food waste, making it easier for your septic system’s natural bacteria to process.
Q3: Do I need to add enzymes or treatments to my septic tank if I use a garbage disposal?
A3: If you choose a “septic-safe” disposal with a built-in enzyme system (like the Septic Guard models), you might not need to add additional treatments as frequently, as the disposal does some of the work. However, always consult with your septic system professional. Regular maintenance and occasional enzyme treatments for your entire septic system are generally good practice, especially with garbage disposal use.
Q4: What types of food waste should I avoid putting down a garbage disposal with a septic system?
A4: While septic-safe disposals are powerful, it’s best to avoid:
* Fibrous foods: Celery, corn husks, artichokes, onion skins (can wrap around blades).
* Grease and oils: These solidify and can clog pipes and the septic system.
* Large bones: Even powerful disposals can struggle, and dense materials don’t break down well in a septic tank.
* Coffee grounds, pasta, rice: These expand with water and can create sludge.
* Fruit pits, nutshells: Too hard for most disposals.
Sticking to softer, smaller food scraps will help prolong the life of both your disposal and septic system.
Q5: How does horsepower (HP) relate to septic systems?
A5: Higher horsepower (e.g., 3/4 HP or 1 HP) generally means a more powerful motor that can grind food waste into finer particles more efficiently. A finer grind is always better for septic systems, as it reduces the solid load and prevents clogs. While 1/2 HP can work, higher HP models are generally preferred for optimal septic health.
Q6: How often should I run water when using my garbage disposal?
A6: Always run a strong stream of cold water before, during, and for at least 15-20 seconds after using your garbage disposal. This helps flush food particles completely through your drain pipes and into the septic tank, preventing accumulation and potential clogs in your plumbing.
Q7: How can I maintain my septic-safe garbage disposal and septic system?
A7:
* Regular Cleaning: Grind citrus peels (like lemon or orange rinds) to clean and freshen the disposal. You can also use disposal cleaner products.
* Avoid Overloading: Don’t stuff large amounts of food in at once.
* Consistent Water Flow: Always use plenty of cold water.
* Regular Septic Pumping: Adhere to your septic professional’s recommendations for regular septic tank pumping (typically every 3-5 years, but this can vary with garbage disposal use).
* Be Mindful of What Goes Down: Even with a septic-safe disposal, avoid putting non-food items or problematic food types down the drain.
