Garbage Disposal Myth-Busting: What It Really Can Handle (And When It’s Time to Call NorthStar) By NorthStar Plumbing & Drain Cleaning. Serving Fargo, West Fargo, Moorhead & surrounding areas. Your kitchen sink’s garbage disposal is a handy appliance when used properly. But there are a lot of myths floating around about what you can (and can’t) toss down, what weird sounds mean, and when you should consider replacing the unit altogether. In this post we’ll clear things up so you can get the most life out of your disposal and know when it’s time to call in the experts at NorthStar. What Your Garbage Disposal Can Handle: Myth to bust: “If I scrape everything into the sink, my disposal will take it.” Reality: You can put many food scraps in there, but you still must be selective. Overloading, tossing in hard/indigestible items, or ignoring proper use will shorten the lifespan and increase the risk of clogs. It’s easy to assume that your disposal can eat just about anything left on your plate. The truth: modern units are quite capable but they’re not invincible. Here are some guidelines: • Soft or liquid food wastes are generally fine. According to home-appliance experts, if you can chew it, your disposal likely can handle it (assuming you use cold water and run the unit properly). • Occasional use of ice or citrus rinds helps clean and refresh the disposal. • Chop up larger pieces of food waste before feeding into the disposal. This reduces strain on the motor and blades. • Consistent use + good maintenance = longer life for the unit. What Your Garbage Disposal Cannot / Should Not Handle: Here’s where many problems start. When you feed your disposal things it wasn’t designed to handle or neglect proper usage, you set yourself up for troubles like jams, clogs, or motor burnout. Here are usual culprits: • Grease, fats, oils: These may go down when hot, but cool and solidify in the pipe or disposal, building up over time. • Fibrous vegetables (e.g., celery strings, onion skins, artichokes) the fibers wrap around the blades or impellers and impair function. • Egg shells, large pits/fruit seeds, large bones: Hard items may damage the blades or simply not grind down properly, leading to blockages. • Pasta/rice in large quantities: They may expand, swell or create sludge after being partly ground. • Non-food items (metal, plastic, glass), too much at once, or items that should go in the trash or compost. • Overloading the unit or expecting it to handle major cleanup of the day in one go. Tip from NorthStar: Before running your disposal, turn on cold water, feed food gradually, run the disposal for a short time, then flush with cold water for ~20-30 seconds afterward. This helps wash away remaining particles and keeps the drain flowing. Odd Sounds & Other Warning Signs: When Something’s Wrong Your disposal should operate with a certain background of hum when running, but when the sounds change, that’s a red flag. Here are signs to listen for: • Humming or whirring without grinding: The motor is powered, but the blades or impellers may be jammed or stuck. • Rattling or loud grinding/clanking: A foreign object (cutlery, bone fragment) may be loose inside, or internal components are loosening/damaged. • Squealing or high-pitched noise: Possibly a failing motor or misaligned flywheel. • Slow drainage: The disposal may grind, but the sink is slow to clear could indicate wear or partial blockage. • Persistent odors: If your disposal smells even after cleaning, food may be trapped inside, or the unit is deteriorating. If you hear or observe any of these signs, it’s wise to stop using the disposal and give NorthStar a call before the issue escalates into a full blockage or leak. When Should You Replace Your Garbage Disposal? While a well-cared for disposal can last many years, it won’t last forever. Here’s when replacement becomes a better option over repeated repairs: • The unit is 10+ years old (typical lifespan is around 8-15 years) and starting to show multiple issues. • You’re resetting the unit often, or it simply won’t turn on. • Leaks under the sink from the disposal unit itself (not just from a pipe connection) sealing/gasket damage means risk of water damage. • Multiple warning signs from above (odd noises + slow drain + smells) happening together. • The cost of repeated repairs is approaching the cost of a new unit. Bottom line: If you’ve been careful and still facing recurring problems, replacing the disposal may save $$$ in the long run and avoid kitchen catastrophes. NorthStar’s Tips & Best Practices for Life-Long Disposal Health Here are some practical pointers from NorthStar Plumbing to keep your disposal and sink running smoothly: • Run cold water before, during, and after using the disposal. Cold water keeps fats from liquefying and then solidifying further down the drain. • Feed waste gradually, don’t dump a whole plateful of heavy scraps in at once. • Avoid the "everything gets dumped in the sink" mindset. Scrape off large bones, shells, fibrous veggie parts into the trash or compost first. • Use the disposal regularly, even if just for small scraps, to keep the mechanisms moving. • Clean your disposal monthly: a few ice cubes + a bit of citrus rind can help clean the unit and refresh the smell. • If you hear noise changes, or the sink is draining slow, don’t “wait it out”, catch issues early. • And of course: If you’re unsure, or something doesn’t feel right, call NorthStar for an inspection or service.
