Fixing a Rainbird 100-HV-NPT Valve Won't Shutoff 

That was actually helpful watching that rain bird video. I started up for the season and one of the valves was stuck on. After seeing how it worked I manually opened the valve to purge it and then it was able to turn off

Did it work long term? Was the rock the only issue?

The voltage is actually around 21 volts alternating current so it could probably tickle your tongue 🤪
