Sprinkler Spacing Guidelines
Precipitation Rate Formulas
• Square Spacing
No wind - 55% of diameter
4 mph wind - 50% of diameter
8 mph wind - 45% of diameter
• Triangular Spacing
No wind - 60% of diameter
4 mph wind - 55% of diameter
8 mph wind - 50% of diameter
• Single-Row Spacing
No wind - 50% of diameter
4 mph wind - 50% of diameter
8 mph wind - 45% of diameter
Note: Designing for zero (0) mph
wind conditions is not recommended.
Design for worst wind conditions.

Toro Swing Joints
Use Toro swing joints to connect the sprinklers to the lateral/main line pipe.
Toro swing joints provide swivel joints that allow the sprinkler body to be easily positioned
to finished grade and prevents pipe breakage by providing the flexibility to allow downward
movement if the sprinkler is run over by heavy equipment.
For installation using pipe thread connections (NPT or BSP), use PTFE tape only to seal
all threaded connections.
CAUTION: Use PTFE tape only for sealing pipe thread connections. Use of pipe dope or
other paste sealants can cause deterioration of the sprinkler body threads.
Tape should be applied to the male threaded fitting in compliance with the tape manufacturer
recommendations. Thread the fitting into the mating female threaded fitting in the sprinkler
body and service tee and tighten securely.
For installation using ACME thread connections, do not apply additional sealant.
CAUTION: ACME fittings incorporate an o-ring seal that requires no additional sealant.
Sprinkler fitting installation - Thread the ACME fitting into the sprinkler body and hand tighten until it stops. No
additional tightening or loosening is required.
CAUTION: Loosening beyond 270° will result in a thread leak.
Lateral/Mainline pipe installation - Thread the ACME fitting into the lateral/main line service tee and hand tighten until
it stops, then loosen up to one full turn to ensure flexible movement of the swing joint.
Figure 1
Wire Splices
CAUTION: Communication cable or station wire connections will deteriorate when exposed to moisture and earth
ground causing shorts or open circuits resulting in improper system operation.
All direct burial wire connections must be done with approved waterproof connections installed in compliance with the
manufacturer specifications. Contact your Toro Golf Distributor for approved waterproof connectors.
Always provide a wire service loop for each splice to ensure sufficient wire is available should future servicing be
required.
Connecting Hydraulic Control Tubing
Step 1 – Route control tubing from the controller to the sprinkler location(s).
Note: Leave an 18" (45.7 cm) service loop of tubing at each sprinkler to facilitate movement of sprinkler and
service operations. Refer to Hydraulic Control Systems Table for tubing run length and sprinkler elevation
information.
Step 2 – Flush tubing thoroughly to remove all air and debris.
Step 3 – Remove the tube retainer and poly cap from the tubing adapter at the base of the sprinkler.
Step 4 – Slide the tube retainer over the end of the control tubing and attach tubing to adapter.
Step 5 – Slide tube retainer over the adapter area to secure tubing.
Hydraulic Control Systems Table
Maximum Distance
Type of System* From Controller Elevation Restrictions
Normally Open (01) Valve elevation should not exceed
with 3/16" Control Tubing 500' 25' above controller elevation or
70' below controller elevation.
Normally Open (01) Valve elevation should not exceed
with 1/4" Control Tubing 1000' 25' above controller elevation or
70' below controller elevation
* - All hydraulic connections on Toro valves are 1/4" insert type.
- Control line pressure must be equal to or greater than mainline pressure.
- Control line pressure range is 40 to 150 PSI.
System Start Up
WARNING! Never stand or lean over the sprinkler while the irrigation system is being filled, during manual or
automatic operation or when performing sprinkler service procedures. Direct contact with irrigation spray, a failed
or improperly installed sprinkler connection or sprinkler components forcibly ejected upward under pressure can cause
serious injury.
The following is a recommended procedure that will protect system components during system start-up. The procedure
is based on a velocity fill rate of less than 2' (.61 m) per second. See Table 3 below.
Step 1 – Use a jockey pump only to fill the system at a velocity fill rate of less than 2' (0.61 m) per second.
CAUTION: Failure to comply with recommended fill rate will increase line pressure resulting in a water
hammer effect that could damage sprinklers and piping components. See Warning above.
Step 2 – Use quick coupler keys at all tees and greens with quick coupler valves to bleed air from the system
lines during the filling process. For best results, do not compress air and then relieve it – bleed the air
continuously while filling the system.
Step 3 – After water has filled all lines and all air is removed, remove the quick coupler keys.
