[.ca] Watering Systems for Lawn and Garden: A Do-It-Yourself Guide (ISBN 0882669060)

Misleading title:
This book is titled for DIY but nearly every chapter seems to start with advising us to consult with and/or hire a professional. I got more information on planning and layout from websites of system manufacturers than from this book. There is a reasonably good summary of different types and it might be OK as a guide if you're planning on hiring a professional anyway but this is not a DIY nuts and bolts kind of guide.
