Kitchen Sink with Garbage Disposal

 

Have you ever seen what went down the drain come back up-or possibly worse, get stuck? It’s not the most appetizing picture-or smell.

A friend shared with me a heartwarming story of a recent family gathering. They showed up at the host’s home baring bottles of wine, artichoke dip, and the obligatory assorted veggie tray. With bright grins they rang the doorbell ready to make merry with their loved ones. The door opened, and they were met with a mom and dad with heavy bags under their eyes-exhausted, but happy to see them.

“What happened?” my friend asked. His mother looked at his father and said two words “garbage disposal.”

The night before the parents had been happily preparing the feast for the next day when a geyser of potato peels exploded from their kitchen sink. While peeling away, my friend’s dad decided to shove all the peels down the garbage disposal. Amidst the starchy sludge that now graced the kitchen, he tried using a 25 foot drain snake to unblock it, but to no avail.

Calling several local plumbing companies at 9:30PM on the eve of a holiday (to which I reminded them, I work for a fantastic plumbing company and am, myself, a master plumber) and eventually got a service tech to come out between the window of 12:30AM – 3:00AM. An industrial auger, no sleep, and $400 later, the blockage was gone and they got back to worrying about basting and who would get the wishbone.

These types of emergencies are easily avoided by knowing that just because something can fit down the drain, doesn’t mean it should go there. Below is a list of “Don’ts” for your garbage disposal.

Coffee Grounds

Not Safe for the Garbage Disposal:

  • Nuts
  • Bones
  • Seafood Shells
