Value problem
System worked 100% a little over a week ago. Cut water source off to isolate system while trying to find something that could cause water bill to skyrocket. Concluded it was not sprinkler system, so open water to system and wanted to run throught the five zones in manual mode. Problem....after one week, zones 3 & 4 work just fine....1, 2, and 5 act as if there is no water. Any thoughts please?
Thanks,
