dd,

It is indeed very simple but takes some research and planning. Without a description of your system and number of irrigation heads, it would be difficult to guide you. Please research information on Google (there is plenty of very good information. Also garden stores and big box stores have a wealth of info and help. For us to help you further in the detail and as you have more questions, we would need the flow rate and pressure of your water source. I can help you on how to figure your pressure and flow rate if you need it. Aloha
