I found Water Distribution Modeling very helpful. It went into more detail and explained the aspects of modeling and water distribution in general much better than the user's manual. I highly recommend any serious modeler to make this purchase. I found it very helpful for explaining the process of developing a system head curve for modeling pumps in parallel. The book really simplified the process to something that I could understand.
