It’s the sound every San Diego homeowner dreads: you flip the switch, and instead of a powerful whir, you hear a sickening thud or a low, ominous hum.
At Perry Plumbing San Diego, we repair hundreds of disposals every year in neighborhoods from Chula Vista to Escondido. While these machines are tough, they aren’t industrial shredders. In fact, San Diego’s “very hard” water can make disposal clogs even tougher to clear because minerals like calcium create a sandpaper-like surface inside your pipes that food loves to cling to.
To keep your kitchen running smoothly, keep these four “culprits” out of your sink.
1. F.O.G. (Fats, Oils, and Grease)
This is the #1 cause of kitchen plumbing emergencies in San Diego.
- The Problem: Grease might be liquid when it’s hot in the pan, but as soon as it hits your cool pipes, it solidifies into a waxy “plug.”
- The Hard Water Twist: In San Diego, the high mineral content in our water can react with fats to create “fatbergs”—rock-hard blockages that are nearly impossible to clear with a standard plunger.
- The Fix: Pour grease into an old coffee can or glass jar and toss it in the trash once it cools.
2. Stringy and Fibrous Vegetables
Think celery, corn husks, onion skins, and asparagus.
- The Problem: These vegetables have long, tough fibers that don’t actually get ground up. Instead, they act like a “nest,” wrapping around the disposal’s impellers and eventually burning out the motor.
- The Fix: These items belong in your green organics bin or compost pile, not your drain.
3. “Expanding” Starches (Pasta, Rice, and Bread)
Have you ever left a pot of spaghetti in water overnight? It grows.
- The Problem: Pasta and rice continue to absorb water long after they leave your sink. Even if the disposal grinds them up, they can swell inside your P-trap, creating a thick, glue-like paste that completely seals off the pipe.
- The Fix: Scrape those leftovers into the trash before rinsing your plate.
4. Eggshells (The “Sharpening” Myth)
You may have heard that eggshells help “sharpen” the blades. This is a myth.
- The Problem: Disposals don’t actually have blades; they have blunt impellers. The thin membrane inside an eggshell can wrap around the moving parts, while the “sand-like” shell fragments settle in the pipes, catching other debris until a clog forms.
- The Fix: Eggshells are great for your garden soil, but terrible for your plumbing!
Quick Troubleshooting: The “Reset” Trick
Before you call us, try this:
- Turn off the disposal.
- Look at the very bottom of the unit under the sink.
- Find the small red reset button.
- If it has “popped” out, push it back in. This is a built-in circuit breaker that triggers when the motor gets too hot.
Still Stuck? Call the Pros.
