Breakdown
Full review
A 4 inch body with pressure-regulated service notes
The Rain Bird 1804HEVNPR is a 4 inch pop-up sprinkler in the Rain Bird 1800 series. It includes an HE-VAN adjustable nozzle, pressure regulation, and SAM check-valve support for compatible sprinkler zones.
This is the kind of head that benefits from a clear station note. The body style, pressure-regulated role, nozzle radius, arc setting, and head location should stay together in one record.
Keep nozzle and body details together
The included HE-VAN nozzle still needs the same careful handling as a separate nozzle refill. Keep the screen clean, set the arc with the watered edge in sight, and write the radius and head location while the zone is running.
If the station includes a mix of body styles, label the pressure-regulated head clearly in the service note.
Finish with a measured check
Run the zone after installation and watch the head rise, spray, and retract. A catch cup can give the finished setup a simple output reading, and a flag can mark the checked spray edge.
Store removed pieces in a labeled bag until the station has run cleanly.
