Homeowner and Technician Guide to Installing a Rain Bird Spray Body on a Swing Assembly

Learn how to excavate, connect, flush, level, position, test, and backfill a residential spray head.

Updated August 5, 2026 Hunter HydroTech LLC Michigan Irrigation Knowledge Center

A residential spray head should be connected with a flexible swing assembly, positioned at the correct height, and adjusted as part of the complete zone.

Typical connection

CRE or CRT → 050 swing elbow → swing pipe → 050 swing elbow → spray body

Installation steps

  1. Run the zone and verify the actual problem.
  2. Dig approximately 6 to 8 inches around the head.
  3. Inspect the nipple, swing assembly, CRE, or CRT.
  4. Replace damaged fittings as needed.
  5. Install two compatible 050 elbows with swing pipe between them.
  6. Leave the head off and flush the line outside the hole for 15 to 60 seconds until the water is clear.
  7. Inspect the open fitting for dirt or stones.
  8. Install the spray body and set it level with the soil.
  9. Keep the body about 2 to 3 inches away from sidewalks and driveways where practical.
  10. Install the correct nozzle and adjust the pattern.
  11. Run the zone and confirm pressure, coverage, retraction, and leaks.
  12. Backfill evenly while keeping the body straight.

When professional service is recommended

Professional service is recommended when the repair involves a damaged CRE or CRT, active fitting leak, valve replacement, wiring, poor pressure, or repeated failure.
