showing water flow but zone not active after water turned off at street for tankless plumbing rep.

i checked backflow preventer and was able to confirm water/flow was getting from city connection to irrigation lines. i discovered that by opening the main solenoid valve by hand i was able to manually open each additional solenoid valve to get all zones operational (again, manually). i am now only able to remotely activate two zones through my rachio app, and only when the main solenoid valve is manually set to “open”. other three zones do not activate through app. does this mean i have some bad solenoids? they are hunter. i live in austin and was very happy to see that my system seemed to have survived our recent freeze when i activated and checked all the zones (which worked) 3 days ago. now, when i go to manually start a quick run my app shows any given zone as watering, but no water…from any of my 6 zones. there is also no flow when i manually turn the solenoid valves at any location. add to this the fact that 5 minutes after i was outside trying to manually operate the zones, i turned around and saw that one zone had been successfully started at it’s normal programmed start time…but only ran for 3 of it’s programmed 20 minutes. i’ve unplugged/replugged my outside controller. checked the wiring at the main unit. and rebooted my phone and main router. all leading to the app displaying my zones are active, but no water flow at the heads. any tips? should i start investigating the main backflow preventer or any other water supply source?

Interesting investigation. You're sounding like a professional to me. Unfortunately, if I would have a problem like this one, I couldn't resolve it myself. I guess I'm still scared of facing issues like this one :) My mother always has told me that it is better to hire someone who has learned very much and understands how to proceed in this kind of situation. My only advice for you is to contact a good plumbing company that is from your region, of course. I'm using their services https://www.wilcoplumbing.com.au/plumber-killara/ and have not been disappointed once. No matter what kind of issue, do you have they offer 24/7 emergency plumbing and fast arrivals. You can check their site and see for yourself.
