Using the Test All Valves feature on a sprinkler timer

Step by step instructions for using the Test All Valves feature on a lawn sprinkler controller. Test All Valves is a feature on newer timers that allows you to test all of the stations on a sprinkler system in sequence regardless of what program they are on in one step. Note: Only valves/stations with non-zero watering times will run with this feature. Test default run time in minutes for the valves can changed to any number desired before running the test. In this video I demonstrate the Test All Valves feature using a Rain Bird ESP Series 4MI indoor modular controller.
