Rain Jet Sprinkler System: Identify Controller vs. Manual Valves

First Step: Determine System Type

The user has "Rain Jet" on sprinkler heads but no controller visible. Need to clarify:

• Is there a controller (timer) with "Rain Jet" on it? → Automatic system.
• Or only manual valves in boxes? → Manual system.

If Automatic

Locate the controller (garage, basement, outside). Program it to run zones. The "3 small black plastic covers" may be valve boxes.

If Manual

Turn on the main supply valve, then manually open each zone valve (usually a tee-handle with a key).

Service Area Note

The responder only services Phoenix, AZ and Denver, CO. For other areas, contact a local irrigation contractor.

Replacing Heads

Rain Jet heads are obsolete. Match throw distance and GPM to modern heads (Rain Bird, Hunter, Toro).
