I am hoping to start my irrigation system up myself this year, and save a little money. I just had it installed by a a company last fall and ran it only a few times before they came and winterized it. My questions are the steps i need to take to turn it on. I noticed that they pulled the drain/blow-out plug, so i'll need to reinstall that. I also noticed the backflow valves are shut, and so are the valves in the two control boxes i have. Is this the order that i go about turning the system back on? 1.) Install the drain plug 2.) turn on the backflow valves 3.) turn on the valves in the control box 4.) turn on the water supply 5.) turn on each zone and adjust the spray if needed (i'm familiar with this) I have a submersed well and it's clean and all, so i am ready to go there. Any additional things, or are my steps wrong? Any of your expert advice is appreciated. Thank you!
