Rain Bird sprinkler maintenance

Three common failure modes

failing to rotate

particularly older R-50 rotors

leakage - riser seal failure

sand - maintain a small moat around heads to reduce wear
can replace riser without fully digging up outer shells
1804 riser seals leak more with lower water pressure

mower damage

bury deeper

nozzle failure

they are replaceable

5004 with check valve

3/4" pipe thread, nozzle inserts in head
head is integrated with riser

1804-SAM   R-VAN instructions

1/2" pipe thread, R-VAN head with nozzle screws into riser

5000 PC (part circle) left and right stop

Left stop (CCW)

unscrew riser from body, grab toothed riser bottom
- rotate gently whichever way clicks
- click direction reverses at limits
- rotate top to CCR (left) click limit
- with nozzle pointing in desired left limit direction,
  lower riser into body, engaging toothed bottom on body ridges
  screwing riser CR into body will rotate riser toward right stop,
  but should not go beyond right limit

5000 Nozzle selection

Low Angle (LA) 1.0. 1.5, 2.0 or 3.0 GPM

for windy areas (not Sun City)

Rain Curtain 1.5, 2.0, 2.5, 3.0, 4.0, 5.0, 6.0 or 8.0 GPM

No appreciable curtain effect, in my experience, occurs until
a grub screw above the nozzle reaches into its water stream.

History

9 May 2022
----------
ordered Rain Bird
 5004-FC (x2),
 5004-PC-SAM (x3),
 1804SPRS-RVAN14 (x4)

20 May 2022
-----------------
Zone 4 replaced full circle head, reduced nozzle from 5.0 to 4.0,
with much less screw protrusion, deflecting less water near the head.
Leaking Zone sprinklers at curb west of driveway
had been replaced June 2019.. but NOT SAM; replaced now by 1804SPRS-RVAN14s
RVAN adjust: left is fixed (see line) push down and rotate rotor for right side.
Collar below adjusts pressure/distance.
