Having a garbage disposal can be incredibly convenient, but when you also have a septic system, there are some significant limitations. Improper disposal practices can lead to costly repairs and system failure. This guide details what absolutely should not go down your garbage disposal if you're on a septic system.
Why is Garbage Disposal Use Different with a Septic Tank?
Septic systems rely on a delicate balance of bacteria to break down waste. Unlike municipal sewer systems, which handle a much larger volume and variety of materials, septic systems have a limited capacity and are more easily overwhelmed. The wrong materials can disrupt the bacterial ecosystem, leading to clogs, pump failures, and expensive repairs or replacements.
Foods to Avoid Putting Down the Garbage Disposal with a Septic Tank
Many common kitchen scraps are absolute no-nos for septic systems:
-
Grease and Oils: These solidify as they cool, coating pipes and contributing to clogs. This is a major problem for septic tanks, as it can drastically reduce the efficiency of the system. Always wipe grease from pans into the trash.
-
Starchy Foods: Large amounts of starchy foods like pasta, rice, and potatoes can create a thick sludge that is difficult for bacteria to break down. This sludge can build up and cause clogs both in your pipes and your septic tank.
-
Fibrous Foods: Foods high in fiber, such as celery, onion skins, and corn husks, can get tangled and cause clogs in the disposal and pipes. They are also difficult to break down in a septic system.
-
Egg Shells: Although some sources suggest they're okay, the sharp edges of eggshells can damage your garbage disposal's blades and contribute to clogs. It's best to err on the side of caution and dispose of them in the trash.
-
Coffee Grounds: While often touted as beneficial for gardens, coffee grounds can clump together and contribute to blockages in your pipes and septic tank.
-
Bones: These are extremely difficult to break down and can easily damage your garbage disposal's blades.
Other Items to Keep Out of Your Garbage Disposal (Septic or Not!)
Beyond food waste, here are additional items to avoid, regardless of whether you have a septic tank or not:
-
Hard objects: Metal, glass, or plastic items can damage the blades of your garbage disposal.
-
Chemicals: Harsh chemicals can kill the beneficial bacteria in your septic system, hindering its function.
-
Excessive amounts of food waste: Even appropriate scraps should be added sparingly to prevent overloading the system.
What about fruit pits and peels?
Fruit pits and peels are generally okay in smaller amounts, but it's best to avoid putting too many in at once. They can also contribute to clogs if you use excessive quantities.
What if I accidentally put something down the disposal that shouldn't be there?
If you accidentally put something down the garbage disposal that shouldn't be there, try running cold water down the drain for several minutes. If you suspect a clog, it's best to contact a plumber specializing in septic systems.
How Can I Maintain My Septic System?
Regular septic tank pumping is crucial, generally every 3-5 years, depending on usage. This prevents buildup and ensures efficient functioning. Also, avoid overloading your system with unnecessary waste and follow the guidelines mentioned above.
Remember, a properly functioning septic system is essential to your home's health and value. By understanding what not to put down your garbage disposal, you can extend the life of your system and avoid costly repairs.
