A master valve that will not open looks like a dead system. A master valve that will not close looks like a leak on every zone. Texas HOA manifolds hide them. Diagnose the master before you condemn every station.
No water on any zone
If every station is dead, check rain sensor, then master valve, then water supply. Replacing four solenoids is the wrong first move.
Water with the clock off
A master that will not seat pressurizes the whole manifold. Meter test, then that valve, then laterals.

How we actually run this job
On the truck this is still isolation before dirt, a written option before extra parts, and a legal watering window after the hardware works. Texas clay, caliche, and city mains punish skipped steps. If a national checklist contradicts your utility, the utility wins.
If you are comparing cities, use the local page rather than this article alone — soil and freeze risk change at the county line. The service menu is here and the area list is here.

Texas context we will not skip
Gulf clay, Blackland prairie, and Edwards rock do not share a repair script. A wet spot in Houston is not a freeze crack in Dallas, and a SAWS stage day is not a MUD watering window in Katy. We write those constraints because they change the parts on the truck and the program we leave on the clock.
If this article is about a part, still run isolation before you buy a case of that part. If it is about a city, still open the valve box before you trench the first damp patch. If it is about a clock, still measure the solenoid. That order is the whole business.
