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.

NSTALL 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

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.

or 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.

unny 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.

MAIN AND LATERAL LINE TRENCHING

Remember to have all utilities marked before you begin

trenching to prevent serious injury. Call your local

utilities or dial 811.

To soften the soil when trenching with a

hovel, water the ground approximately two days before you

dig. Dig trenches 8" to 12" deep. Put sod on one side of the

trench and soil on the other.

Trenching machines are an easier, faster alternative to digging

with a shovel. Typically, Toro trenching machines can be rented

from a lawn supply store or rental equipment dealer. The store

or dealer can show you how to operate the machine properly.

INSTALL THE SYSTEM MAIN LINE

Attach the main line to the service line. Run it along the bottom

of the trench from the house to the first set of valves, and if

necessary, to the second set of valves. Place the valve wires

under the pipe in the bottom of the trench whenever possible.

A. Working with PVC Pipe:

1. Cut pipe with a PVC pipe cutter.

2. Brush on a primer to clean the pipe surface and the inside

of the fitting.

3. Brush glue on the outside end of the pipe lightly inside

the fitting.

4. Slip the pipe into the fitting and give it a quarter turn.

5. Hold in place for about 15 seconds so the glue can set.

6. Wipe off excess glue with a rag.

7. Wait at least one hour before running water through

the pipe (check manufacturer’s recommendations).

B. Working with Poly Pipe:

Do not use poly pipe as a connecting pipe between the service

line and the control valves. Surge pressure may rupture the pipe.

Check your local codes for the correct type of pipe to use.

1. To relax poly pipe, expose it to sunlight. (Never expose to

open flame.)

2. Cut pipe with a PVC or poly pipe cutter.

3. Slip a stainless-steel clamp over the end of the pipe.

4. Insert the barbed fitting into the end of the poly pipe,

past the barbs.

5. Slide the clamp over the barbs of the fitting.

6. Tighten the clamp.

STEP 2: Install Valves

BUILD VALVE MANIFOLDS

A group of valves is called a valve manifold. Use flags to mark

the location of the valves as indicated on your irrigation design.

. Anti-Siphon Valve Installation

Anti-siphon valves are a combination of a valve and

atmospheric backflow preventer and are always installed above

ground. Some sort of backflow prevention is required on every

irrigation system so check building codes in your area to find

out if an anti-siphon valve will work for you. Dig out an area

large enough to accommodate your inlet and outlet pipes.

B. In-Line Valve Installation

In-line valves are installed below ground and require a

separate backflow device. Protect valves below ground by

sheltering them in a valve box. Dig out the area where the

valves are to be installed. Install the valve box at or below

grade level. When purchasing a valve box, be sure to find out

how many valves fit in each box so that you can be sure to

purchase the correct number of boxes. In some cases, you

will need more than one valve box per manifold.

In cold or freezing climates, where poly pipe is used

instead of PVC, a vibratory plow is used for pulling pipe.

Deeper trenching may also be necessary.

SHUT-OFF VALVES

We recommend installing a shut-off valve between the

zone valves and the service line. This will allow you to

easily turn off the water to your irrigation system if you

need to make repairs or replace parts. Check local codes

for the type of shut-off valve recommended.
