Just how do they keep their hands so clean?  This course won't help figure that out but it is a good look at all the different ways we see electricity in our plumbing systems.  Thermostats, freeze protection, switches, valves, pumps, faucets, etc.  There is more than you might think.  What made the dishwasher explode in the house?  How can you keep a sewage ejector from freezing?  Don't ask sparky, take this course!
