Why is one sprinkler zone not working?

Thumbtack Editors
Answered

One sprinkler zone could be malfunctioning for several reasons, although the most obvious one — a closed valve — is often the culprit. Check to see if the main system valve is closed. It’s easy to forget to turn this back on after repairs. Other causes for failed sprinkler zones are electrical issues within the valve, timer, wiring or solenoid. A common reason is a bad connection that needs to be re-soldered.
