Understanding what this means in context of how sprinkler valves operate will help you determine when your sprinkler valves should be open and when they should be closed. Well, yes and no – it all comes down to the difference between manually opening or closing your sprinkler valves and allowing your control box or timer to do it for you. Does this mean the valves are closed and preventing water flow through to your sprinklers? When taking a look inside your valve box, it can be confusing to see your solenoids in the ‘off’ position when you want those valves to be open.

Without these valves, we’d have a much more difficult time telling our sprinkler system what to do, and automated valve control has made backyard irrigation more convenient than ever before. Sprinkler valves are a vital part of any irrigation system, translating the instructions from the main control box into changes in water flow.
