Protect Your Plumbing: 5 Foods Plumbers Warn Against Disposing Of

21

Garbage disposals are a modern kitchen convenience, but treating them like a trash can can lead to expensive plumbing problems. Plumbers consistently advise homeowners to use disposals sparingly – only for small, soft food scraps. Overloading or misusing these appliances is a quick way to clog drains and require professional repairs.

The Golden Rule of Garbage Disposal Use

The core principle, according to plumbing experts, is simple: if you wouldn’t easily compost it, don’t put it in the disposal. Brian Stigner, a senior regional director at Service Experts, emphasizes that disposals aren’t designed for bulk waste. They work best as a last resort for minimal leftovers, not as a replacement for proper waste disposal.

Foods to Avoid at All Costs

Certain foods are particularly problematic for garbage disposals. Here’s what plumbers warn against:

  • Fats, Oils, and Grease: These congeal in pipes, causing odors and stubborn clogs over time.
  • Pasta and Rice: These starches expand with water, creating a sticky mass that jams the disposal.
  • Eggshells: Despite the myth, eggshells don’t sharpen blades; they contribute to sludge buildup.
  • Bones: Too hard for most disposals to handle, bones can damage the grinding mechanism.
  • Potato Peels and Coffee Grounds: Fibrous materials like these wrap around blades, causing blockages.

Proper Maintenance for a Long-Lasting Disposal

To keep your disposal running smoothly, always run cold water while it’s operating. This helps break down food and flush it through the drain. Zack Kutchma of Whirlpool notes that without water, food will accumulate and cause issues. Additionally, regular cleaning is essential. Consider using a disposal cleaner like affresh, or periodically grinding ice and lemon peels to remove residue and odors.

Know When to Call for Help

Plumbers advise keeping an eye out for warning signs. Slow draining, full sink clogs, unusual grinding noises, foul odors, or frequent reset button use indicate a problem. Never put your hands inside a disposal while it’s plugged in. If you suspect a serious issue, contact a professional immediately to avoid further damage.

Garbage disposals are designed to assist with food waste management, not replace it entirely. Using them responsibly and maintaining them properly will save you money and headaches in the long run.
