Winterizing Rain Jet RJC-6 System: Blow-Out Method

New homeowner with Rain Jet RJC-6 system, no manual. Needs winterizing instructions.

Standard Blow-Out Procedure

1. Shut off main water supply to irrigation
2. Connect air compressor at main irrigation supply (after shutoff)
3. Build compressor pressure (40-80 PSI max for poly pipe)
4. Manually activate ONE zone at a time (controller or valve bleed)
5. Run until only air exits heads (no water mist)
6. Close zone, rebuild pressure, repeat for all zones
7. Leave all valve bleed screws slightly open for winter

Critical Safety

• Never exceed 80 PSI - damages poly pipe and fittings
• Wear eye protection - debris can eject from heads
• Don't stand over heads during blow-out

Professional Service

Most irrigation companies offer winterizing for $50-100 depending on zone count. Recommended if you lack compressor or experience.

Rain Jet Specifics

Rain Jet is obsolete. Valves are standard 24VAC - any irrigation tech can service them.
