Hi, All:
My name is Sam. I am new to this nice forum.
I have purchased a house with a sprinkler system. Initially, the zone 1 and 3 were not working. The previous owner called service and fix them. Now it does not work at all, i.e., none of the zone is working by program or mannual operation.
I have an Irritrol RD-900 Indoor controller with 9 zones. I have checked the voltage from the power supply. It reads 24V. While set manually to zone 1, 2 for example, the MV and zone 1 and 2 also reads 24V. When I turn out the Solenoid from one of the valves, it got very little water comes out of it. First, I thought there was a master water valve turned off. I could not find it, and I have talked with the previous owner. He did not realize there was one. He could not figure out what is wrong with the system either. [

Please help me out. Thank you very much!
