Where did you come up with that?
According to ISE (emphasis added):
DO’S AND DON’TS
• First turn on a moderate to strong flow of cold water and then turn on the disposer. Continue running cold water for a few seconds after grinding is completed
to flush the drain line.
• Grind hard materials such as small bones, fruit pits, and ice. A scouring action is created by the particles inside the grind chamber.
• Grind peelings from citrus fruits to freshen up drain smells. Important – The model LC-50 is designed specifically for light commercial use. Examples of these applications include: grocery/convenience store delis, fast food restaurants, office/church kitchens, and bed and breakfast inns. Use of this disposer in applications other than those named above may void your warranty.
• Use a disposer cleaner, degreaser, or deodorizer as necessary to relieve objectionable odors caused by grease build-up.
I’m not suggesting that inspectors “repair” these devices, but it’s appropriate to be able to tell the client why the plate and/or rams may seize on a unit that hasn’t been run for a while and how it can be addressed without necessarily having to replace the unit.
