Question
My Rainbird 7RCBi sprinkler timer controller comes on and starts in zone 1, but doesn't continue to zone 2.  Is there a part I can still buy and how do I replace it?  Thanks.

Answer
Hi Tim,
This is a pretty old controller, it is discontinued already, I think you can not find parts today. You can replace it with a Rain Bird Esp, the basic unit with 4 stations costs about $ 90 and each additional 3 stations module is $ 27, you can go to rainbird.com or sprinklerwarehouse.com

Regards,
Guillermo
