I have a property with a Hardie Rain Jet HR6100 6 station automatic watering system installed. It currently has 5 of the 6 stations in use. Upon using it this past week, I have discovered that all 5 active stations begin watering at the one time as soon as the water supply is turned on. Is this likely to be a faulty controller, a problem with some of the wiring or a solenoid issue?
