Several weeks ago, while hurrying to get ready to go out to dinner with my wife, I discovered to my horror that I had sprung a leak! That's right, a small crack had developed in a fold of my appliance. My first reaction was: "Oh no, not now" (Actually, those weren't my exact words). My second reaction was: "What can I do? I don't have time to change this thing. Can I patch it?"
Drawing on experience from moving several times, I thought of the tape we had used to seal boxes. You know, that brown plastic tape that is so sticky you can never find the end. Well, I dried off my appliance in the area of the leak and placed a good-sized piece of this tape over the hole. It held! It held through dinner, one night's sleep, a shower, and one day's work! Boy, did it hold! I changed the next evening, right on schedule. Recently, I went to San Francisco on business. Guess what I carried along with my other supplies.
Ed. Note (from Coquitlam): I have resorted to this solution on occasion. The tape also comes in a clear plastic which lets you see when your jury rig is about to fail.
