The 36-year-old bachelor ate his usual lunch at home. He had an apple, a ham sandwich with a sliced dill pickle, a bowl of chicken noodle soup with a couple of soda crackers, and a small candy bar, all washed down with an eight-ounce glass of milk.

      After he finished breakfast, Ed put everything in the sink, poured a little dishwashing soap onto a Teflon pad, and scrubbed the soup bowl, the sandwich plate, and the milk glass. Then he switched on the garbage disposal to grind up the few bits of food that he had scraped off his plate. He left the kitchen to go brush his teeth. But he felt something wet on his bare foot. Sure enough, he looked down and saw some water on the kitchen carpet. “What is this?” he said aloud.

      Opening the cabinet door under the sink, he saw no dripping water. He went to the closet and got a flashlight. When he shined the light into the cabinet under the sink, he saw drops of water on the sides of the dark blue steel cylinder. It looked like he had a leaky garbage disposal. To test his theory, he turned on the switch, and a stream of water flowed out of a seam onto the cabinet floor and then onto the kitchen carpet. Ed had a problem, but he didn’t have time to fix it now. He had to run some errands. He put some tape over the switch so he couldn’t accidentally turn the disposal on again.
