Introduction
The Toro 340 Stream Rotor sprinkler series is designed to deliver maximum watering efficiency and adjust-
ment simplicity. The gentle carrousel spray applies water slowly for minimal run off making it ideal for newly
seeded lawns and planted slopes as well as established landscape areas.
Each 340 sprinkler is supplied with a plastic arc disk
tree providing nine matched-precipitation rate arc
disks. The arc disks, as shown in Figure 1, range
from 90° to 360°, enabling the 340 sprinkler to adapt
perfectly to virtually any landscape design. You may
use any of the Stream Rotor nozzles.
Each of the 340 sprinkler models has their own
unique qualities as well. The Lawn sprinkler pops up
a full 4" (10cm) to clear tall-cut grass and features a
built-in check valve, effective for up to 8' (2.4m) of
elevation difference, preventing seepage from lower elevation sprinklers. The shrub sprinkler has a versatile,
stepped-thread inlet base enabling either 1/2" or 3/4" NTP riser pipe to be used for installation. The High-Pop
model extends nearly 12" (31cm) to easily clear shrubs and tall ground cover. Provided with side and bottom
3/4" NTP inlets, the High Pop installs easily without deep trenching.
Planning Your Installation
Proper application and placement of the 340 sprin-
klers is essential for optimum water distribution.
The illustration in Figure 2 shows a basic sprinkler
layout which provides the required head-to-head
coverage. Quarter circle (90°) spray patterns are
used in each corner, half circle (180°) arcs are
equally spaced on the perimeter and full circles
(360°) are located in the middle. As you can see,
the sprinklers are placed to enable the spray of
each sprinkler to reach all neighboring sprinklers.
Sprinkler Installation Methods
When installing the 340 sprinkler, Toro Funny Pipe
and fittings are recommended for ease of installa-
tion, accurate sprinkler positioning and lateral line
protection. The flexible Funny Pipe link helps pro-
tect the lateral pipe and fittings from damage due to
a forced downward or lateral movement. Figure 3
illustrates how easily Funny Pipe can connect the
various 340 sprinkler models. This is extremely
helpful when replacing sprinklers of different height
or inlet position. Installing the sprinklers on a tradi-
tional swing joint is also an acceptable installation
method. Rigid pipe risers are not recommended due
to the potential for lateral line damage.
