How a Garbage Disposal Works

A disposal isn’t a blender: there are no blades. A motor spins a plate with two swiveling impellers that fling food against a stationary grind ring, breaking it into particles small enough to flush through the drain with running water. That’s why fibrous and starchy foods, bones and grease cause trouble, and why cold water should run before, during and after use.

Repair or Replace?

Most service calls are jams, tripped reset buttons or leaks at a connection, and those are quick fixes. Water leaking from the body of the unit, a motor that hums even after the jam is cleared, or a unit that’s loud and old usually means replacement. We’ll tell you which before we start, and a replacement is usually completed in the same visit.

Getting the Most from Your Disposal

  • Run cold water before, during and for several seconds after grinding.
  • Feed food in gradually, not all at once.
  • Keep grease, oil and fibrous peels in the trash.
  • Clean it by grinding ice and a little dish soap; skip harsh chemicals.
  • Use the disposal regularly so parts don’t rust or seize.

Garbage Disposals in San Jose

Using a disposal well in South Bay kitchens.

  • Keep grease out

    Grease from the disposal hardens in the kitchen line; it's the most common kitchen clog we clear.

  • Older kitchen drains

    Many older homes have galvanized drain arms that narrow over time and clog more easily with disposal waste.

  • Septic and sewer

    Most San Jose homes are on City sewer, where a disposal is fine with sensible use.

  • I just used CPI. I had a drain that my contractor spent 3 days on and couldn’t unplug. I was expecting the worst – I hate wallet pain. My appointment was from 9-11. I expected to wait all day. At 10 am, I get a knock at the door. I open the door. A young man, Daniel, well dressed and groomed appears. He is polite and professional. I let him in, but before he comes in, he respects my house and puts on shoe covers. He sees the clogged sink. I blink, and poof its working. (Ok, maybe not like magic, but he assessed the problem and fixes it.) then he turns on the water to show if it backs up. Now here is the important part. He leaves the water ON. He does not attempt to turn OFF. He wait for me to be satisfied. Watch out Plumbers, there’s a new company in Town.

  • CPI did a great job on some minor plumbing work that I needed done. Their price was fair and scheduling was easy.

  • Consolidated Plumbing has great plumbers, good pricing, and are always there when you need a plumber. All of their plumbers are professional and friendly. I would definitely recommend CPI for any of your plumbing needs.

Garbage Disposal Services FAQs

How do I fix a jammed garbage disposal?

Turn off the power at the switch. Insert a disposal wrench (or a 1/4-inch hex key) in the socket on the bottom of the unit and work it back and forth to free the jam. Remove any object with tongs, never your hand, then press the red reset button and test with cold water running.

Why does my disposal hum but not work?

Something is jamming the plate, or the motor is failing. Turn off the power and free the jam as above; if it still hums, call us.

How long do garbage disposals last?

Often 8 to 15 years, depending on the model and how it's used.

What shouldn't go down a garbage disposal?

Grease, oil, bones, fruit pits, coffee grounds in quantity, eggshells, fibrous peels like celery and corn husks, pasta and rice in large amounts.

Should I repair or replace my disposal?

Jams, reset trips and loose connections are repairable. A leaking housing, a burned-out motor or an old, noisy unit means replacement.
