Installation Guide

STEP 3: Connect Sprinklers and Piping
INSTALL LATERAL PIPE
Start from the valve and move outward, laying the connecting
pipe along the bottom of the trench (more than one pipe may
be laid in a trench). At each flag, install a tee or elbow fitting,
and if needed, a riser for sprinkler attachment. We recommend
that you use Toro Funny Pipe
®
for all your sprinkler head
installations.
INSTALL SPRINKLERS ZONE-BY-ZONE
Using your irrigation design as a
reference, install the sprinklers
one zone at a time, using Toro
Funny Pipe
®
to connect to the
lateral lines.
1. Place a sprinkler in the trench
as a guide and measure from
the connecting pipe fitting to
the bottom of the sprinkler. Cut a length of Funny Pipe
®
to
fit. (Place sprinklers at least 3" from sidewalks and curbs and
6" from fences and buildings.)
2. Install the appropriate Funny Pipe
®
elbow into the sprinkler
and PVC or poly pipe fitting. No glue or clamps are needed.
3. Connect the Funny Pipe
®
to the sprinkler and pipe fitting.
(Do not use more than 4' of Funny Pipe
®
with each sprinkler.)
4. Position the sprinkler in the trench so that the top of the
sprinkler is flush with the ground. Stabilize the sprinkler with
the soil but do not fill the entire trench.
5. Verify the sprinkler is vertical for optimum performance.
6. Repeat this process for each sprinkler.
FLUSH THE SYSTEM TO CLEAR DEBRIS
After the pipe has been connected and the glue has dried (PVC
only), turn on the water, open the valves one zone at a time and
flush the water until it runs clear. If your sprinklers have nozzles
pre-installed, remove the nozzles for flushing.
INSTALL SHRUB HEADS
AND BUBBLERS
Shrub heads and bubblers
should be mounted on
risers that lift them several
inches above the soil
surface. This allows the
spray patterns to reach
maximum radius.
ADJUST THE SPRAY COVERAGE
Turn on each valve, one at a time, to make sure that you are
getting the proper coverage. If not, the sprinklers may need to
be adjusted. Also, most valves include a flow control feature that
reduces wasteful misting and fogging. Follow the instructions
included with the valve to adjust the flow control feature. If the
flow controls are at their maximum and the sprinklers are not
throwing water as far as they should, you may have too many
sprinklers on that valve or line. Double check to be sure that the
installation matches the recommended design.
STEP 4: Install the Timer
1. Install the timer in your garage or other convenient location.
For outdoor installation be sure to use an outdoor cabinet to
protect the timer against the effects of weather. Make sure an
adequate power supply is available.
All outdoor electrical connections must be waterproofed. Use
grease caps for water proof wire connections. See instructions
included with the timer for details.
2. If you haven’t already done so, lay the valve wires in the
bottom of the trenches, beneath the pipes.
3. Connect the valves to the timer using the valve wires.
a. Take one wire from each valve and connect them to a
common wire. (For ease of identification, use the white
wire as the common.)
b.At the timer, connect the common wire to the common
terminal on the timer.
c. Take the other wire from each valve and connect them to
the timer terminals in sequence.
4. Plug in the timer and program per manufacturer’s
instructions.

OPTIONAL: Connecting a Pump Start Relay
If your system will get water from a well, water tank or pond, a
pump start relay lets you automatically activate the pump if your
water supply requires one. For proper function, the timer must
be installed at least 12' from the pump and 5' from the pump
start to prevent malfunctions.

Funny Pipe®
Installing more wire strands than your system currently
requires can be a real time saver. Adding them now is
simple; adding them later after all the dirt is back in
place and the grass is growing is not.
