Orbit valves not opening
Got them fixed - never had this ever happen but FYI - on the orbit valves when you take the cover off to check the diaphragm check and make sure the small chrome rod is still attached to the underside of the cover - without it the valves will not operate. The only thing I can figure they came loose and are down in the manifold but after about 10 minutes trying to fish them out (blindly) with my extendable magnet I gave up and took the tops off another set of valves and put them on.
