So I dont much about this system it was installed before we bought the house i can tell you that it is an orbit system model #57881 and both zones turn on differently...Zone one has to be manually turned on by a little black screw and water leaks out of it when you turn it Zone 2 is turned on by a valve next to the solenoid and zone 2 you can hear massive water rushing
We have a 6 zone system zone 1 and 2 are not working we have replaced the solenoids and the zones do not work by the controller they have to be manually turned on...please help
