We saw above our ceiling and behind our walls last week. We had some drywall replaced in our bathroom and aside from the good work that was done, the best part was the peek "behind the scenes". We live in an OLD building, and seeing the skill that went into construction was a treat - it is quite beautiful and comforting to see that it is NOT all that complicated. We're thinking this book, How Your House Works, might convey a similar type of comfort... We grew up not really learning much about home systems or how appliances work, and feel out of our depth when the possibility of repairs come up - this book might alleviate some stress...as they say, knowledge is power. It is described as being filled with "clear diagrams and concise explanations" for just about every major appliance and building element in your home: Electrical, Heat and AC, Plumbing, Appliances, Foundation, Framing, Doors and Windows. The diagrams are the exploded type, showing "exactly how these things should be put together and how they function – what to check if they don’t work, and what you can do that might save you having to call in a professional". The book is new, published last month, and is available from Amazon for $14.93.
