Why Choose a Septic-Friendly Disposal?
When you have a septic tank, your wastewater isn’t treated by a municipal system. Instead, it relies on a delicate balance of bacteria to break down solids. Regular garbage disposals can overwhelm this system by sending large, undigested food particles into the tank, leading to:
- Increased Sludge Buildup: Food waste adds to the solid layer in your tank, requiring more frequent (and costly) pump-outs.
- Clogs: Larger particles can clog inlet or outlet pipes, or even the drain field, leading to system failure.
- Disruption of Bacterial Balance: Some food types or even excessive amounts can disrupt the beneficial bacteria in your tank.
Septic-friendly disposals, particularly models like the InSinkErator Evolution Septic Guard, address these concerns through finer grinding, and in some cases, the introduction of beneficial enzymes that help break down food waste. This proactive approach significantly reduces the strain on your septic system.
Factors to Consider When Buying a Garbage Disposal for Your Septic Tank
Choosing the right disposal goes beyond just price. Here’s what to keep in mind, especially for septic systems:
- Horsepower (HP): Generally, higher HP (3/4 HP or 1 HP) means a finer grind. Finer particles are easier for your septic tank to process. 1/2 HP can work, but you’ll need to be more cautious about what you put down it.
- Grind Stages: Look for disposals with multiple grind stages (e.g., MultiGrind Technology). These units pulverize food into much smaller particles than single-stage disposals, which is ideal for septic systems.
- Septic-Specific Features: Some models, like the Septic Guard, include a biological enzyme injection system designed to promote healthy waste digestion within your septic tank. This is a huge bonus!
- Noise Level: Higher-end disposals often come with sound insulation technology (like SoundSeal) for quieter operation. Nobody wants a noisy kitchen appliance.
- Durability and Materials: Stainless steel grind components last longer and resist corrosion. Galvanized steel is also durable but stainless steel is often preferred for longevity.
- Ease of Installation: Many modern disposals offer “EZ Connect” or “Lift and Latch” features for simpler DIY installation, which can save on professional costs.
- Warranty: A longer warranty indicates the manufacturer’s confidence in their product. For a crucial appliance like a disposal, a good warranty offers peace of mind.
Conclusion
Finding the best garbage disposal for septic tank 2019 was all about balancing grinding power, durability, quiet operation, and crucially, septic system compatibility. While all the InSinkErator models reviewed here offer solid performance, the InSinkErator Evolution Septic Guard truly stood out for its dedicated septic-friendly features, offering an extra layer of protection for your delicate system.
If you’re on a septic system, investing in a disposal that processes food waste into the smallest possible particles, or even better, actively aids in waste breakdown, is a smart move. It can prevent costly issues down the line and keep your septic system running smoothly for years to come.
FAQ Section
Q1: Can I use any garbage disposal with a septic tank?
A: While technically you can use almost any disposal, it’s highly recommended to use models specifically designed or well-suited for septic systems. Standard disposals can send larger food particles and too much organic matter into your tank, overwhelming its capacity and disrupting the bacterial balance.
Q2: What’s the main difference between a septic-friendly disposal and a regular one?
A: Septic-friendly disposals often feature multi-stage grinding to pulverize food into much finer particles. Some premium models, like the InSinkErator Septic Guard, also include an automatic system that injects beneficial enzymes or microorganisms to aid in breaking down waste in the septic tank, further supporting its health.
Q3: What kind of food waste should I avoid putting down a septic-safe disposal?
A: Even with a good disposal, it’s best to avoid:
* Fibrous foods: Celery, corn husks, artichokes, onion skins.
* Grease and fats: These solidify and clog pipes and tanks.
* Coffee grounds: They can accumulate and create sludge.
* Pasta and rice: These expand in water.
* Large bones: Even powerful disposals struggle with these.
Q4: How often should I use septic tank additives with my disposal?
A: If your disposal (like the InSinkErator Septic Guard) has an integrated additive system, it will dispense automatically. If not, and you choose to use additives, follow the specific instructions on the product. Most liquid or powder enzyme additives are used monthly or quarterly. Consult with a septic professional for personalized advice.
Q5: What horsepower is best for a septic system?
A: For septic systems, a 3/4 HP or 1 HP garbage disposal is generally recommended. Higher horsepower often correlates with finer grinding capabilities (especially with multi-stage technology), which is crucial for minimizing solids that enter your septic tank.
Q6: How do I maintain my septic-safe garbage disposal?
A:
* Run cold water: Always run cold water before, during, and after using the disposal to flush food particles completely.
* Clean regularly: Grind small amounts of ice and citrus peels (like lemon or orange) to clean the grind chamber and freshen the drain.
* Avoid overloading: Don’t stuff large amounts of food in at once.
* Use septic-specific cleaners: If your model doesn’t have an integrated system, you can use septic-safe enzyme cleaners.
Q7: Is an InSinkErator septic guard essential?
A: While not strictly “essential” if you’re very careful with what you put down your drain, the InSinkErator Septic Guard offers an excellent proactive solution. Its integrated enzyme system actively helps break down food waste, providing an added layer of protection and convenience for septic system owners. Many find the peace of mind worth the investment.
