Lawn Maintenance
Why isn't one zone of my sprinkler system turning on?
What’s likely going on
A stuck or broken valve for that specific zone, a wiring issue between the controller and that valve, or a controller programming issue are the usual suspects — and they're easy to mix up without testing each part individually.
Is this a DIY job or worth calling someone?
Checking the controller's programming for that zone is a safe first step anyone can do. A valve or wiring issue means digging near buried lines, which is worth having someone experienced handle rather than risking damage to a line you can't see.
Not sure, or ready to have someone take care of it?
