I bought this book and it was very disappointing. It has nice pictures but leaves out key basic information like the measurements for doing rough-in work for bathroom fixtures. I ended up going to the library to get useful information. This book is perhaps useful for someone who knows absolutely nothing about plumbing but is not good for any one with more knowledge. I consider it a waste of my money
