T
his booklet is intended to be used when designing and
installing small single amily residential sprinkler systems.
It is set up in an easy-to-ollow ormat with illustrations
and helpul charts.
I this is the rst system you have installed, or i you have
installed several systems but have never used this guide
beore, we recommend you look through the next ew pages
and become amiliar with this presentation o the design and
installation process.
You will notice we have included a sheet o graph paper or
your convenience. There are detailed illustrations depicting
suggested installation methods or sprinkler heads, pipe and
valve maniolds, and how to connect the sprinkler main line into
the house water system. Installation tips have also been placed
throughout the guide to assist you in planning a system. AGlossary o Terms is included.
While developing the Gallons Per Minute (GPM), Working
Pressure, and Pipe Sizing charts, we considered reasonable
riction loss and acceptable water velocity or a residential
irrigation system. I you have any questions on the design or
installation process, your best resource is your local Hunter
distributor.
Hunter recommends contracting the services o a proessional
irrigation designer when planning large residential or
commercial projects. Contractors and irrigation designers
can receive additional inormation by contacting their local
Hunter distributor.

A. Plot Plan And Desgn
1. The rst step in designing a residential system is to
measure the property and indicate the location o the
house. On a separate piece o paper sketch out your
property and place your measurements on the sketch.
Be sure to include all concrete or brick walks and patios,driveways and ences. While you are measuring,
locate any trees, shrubs, and lawns and draw them on
the sketch.
2. Next, draw the plot plan to scale on the graph paper
provided. The scale can be 1" = 10', 1" = 20', or
whatever you decide. Write your scale on the plan. Make
sure to note lawn, shrub, ground cover, and large trees.
3. On the plot plan, divide the property into areas. The
areas should be rectangles or squares and as large as
possible. Consider the inormation in Step 2 above while
dividing up the plot plan: ront yard, back yard, side yard,lawn or shrub areas, and shady areas. Label your areas A,
B, C, D, etc. (See the example plot plan above.)

To check water pressure,attach a pressure gaugeto the outside aucetnearest the water meter.A pressure gauge can beobtained rom your localHunter dealer.
B. Determne Sstem Desgn Capact
When planning an ecient automatic irrigation system, you must
rst determine the correct Sprinkler System Design Capacity
how much water is available or residential irrigation. I the systemwill be installed using city water, ollow the steps below. I the
water will be drawn rom a lake or well, your Hunter dealer
or the pump installer will have the specications or pressure
and volume.
1. Water pressre (PSi)
To check the water pressure, attach a pressure gauge to the
outside aucet closest to the water meter. Make sure that no
other water is fowing at the residence. Turn on the aucet and
record the number in the area provided to the right. This is the
static water pressure in pounds per square inch or PSI.
2. Water volme (GPM)
To determine the volume o water available or the system, you
need two pieces o inormation:
A. What size is the water meter?
Water meters will generally have the size stamped on the
meter body. The most common sizes or residential meters
are 5/8", 3/4", and 1". In some areas the water supply hooks
directly into the city main without the use o the water meter.
In these cases, simply enter the size o the service line in the
space provided.
B. What size is the service line?
Measure the outside circumerence o the pipe that runs rom
the city main to the house. An easy way to do that is to wrap
a piece o string around the pipe, measure the string, and
use the table to the right to convert the string length to
pipe size.
3. Sstem Desgn Capact
Using the System Design Capacity Chart on this page, locate
the three numbers you just recorded to determine the Sprinkler
System Design Capacity in gallons per minute (GPM). Record
this number in the GPM box. Next, locate your systems staticpressure and move down that column and nd the systems
working pressure; record it in the PSI box. Working pressure
will be used when choosing sprinkler heads and designing
the system.
You have now established the maximum GPM and the
approximate working pressure available or the sprinkler system.
Exceeding these maximums may result in inecient watering or a
condition reerred to as water hammer, which could cause serious
damage to the system. These two numbers will be used in the
design process.

C. Select Sprnler Heads
There are three basic types o sprinklers or residential use:
large area rotors, rotating stream spray sprinklers and small
area an spray sprinklers. Large area rotors and rotating streamspray sprinklers should never be installed on the same zone as
small area an spray sprinklers. High eciency spray nozzles
such as Pro-Spray
MP Rotators should be
considered in place o
traditional spray nozzles.
1. Large area rotors will cover areas that measure 25' by 25'
and larger.2. Small area sprinklers are typically used in areas smaller
than 25' by 25'.
Within both o these groups are pop-up sprinklers which are
installed even with the grade, and riser-mounted shrub heads,
which are installed above grade.
This 25' by 25' measurement is not a hard rule, rather it is a
guideline. The only consideration restricting the size o the area
in which spray heads (small area sprinklers) can be used is
economics. I a large area rotor can be used, it usually means less
pipe, ewer valves, and a smaller controller will be required to
complete the job.

D. Draw Sprnler Head Locatons
Decide where you will be installing large area sprinklers and
where you will be installing small area sprinklers. Large areasprinklers should be 25' to 40' apart. Small area sprinklers should
be 8' to 17' apart. This spacing will allow sprinklers to overlap
their throw to assure even water distribution. Do not mix sprinkler
types within one area.
Do not place sprinkler heads too ar apart; stay within
specications listed on the Sprinkler Perormance Charts
which may be ound in the Hunter Product Catalog. Spacing
is determined by the size o the area the sprinkler is serving.
Additionally, a sprinkler should be spaced so that it will spray
both the head next to it and the head across rom it. Working
with one area at a time, start placing sprinkler heads:
Step 1. The critical points on a plan are the corners.
Draw a quarter pattern sprinkler in each corner. Using
a compass, draw an arc showing the sprinklers
watering pattern.
Step 2. I the quarter heads will not spray each other
(head-to-head spacing), place heads along the
perimeters. Draw these sprinklers watering patterns.
Step 3. Now look to see i the perimeter heads will be
spraying across the area to the heads on the other side.
I they do not, add ull circle heads in the middle.
An easy way to locate these heads is to draw
perpendicular grid lines rom one perimeter head toanother. Again, using the compass, draw an arc showing
this sprinklers watering pattern to make sure there is
complete coverage.
Step 1 Step 2Corners are critical points. Startby placing sprinklers in eachcorner.
Add sprinklers along the sidesi necessary.
Step 3Larger areas may require sprinklers in the middle, in addition to thesides, in order to provide head-to-head or overlapping coverage.
Convert curved areas to a series o straight lines; place sprinklersthe same as you would in square or rectangular areas. Adjustablearc nozzles on spray heads work very well in curved areas.

E. Dvde Sprnlers into Zones
Unless you have a very small yard, you probably do not have
enough water capacity to irrigate the entire yard at once. Manyareas will require more water than the residence has available
(system design capacity).
You will need to section the yard into zones. Dividing the area
into zones is an easy process. Beginning with area A:
1. Reer back to the working pressure entered on page
2. This is the pressure you will need to use when
determining sprinkler spacing and GPM requirements
listed in the Sprinkler Perormance Charts.
2. Write the individual sprinklers GPM next to each
sprinkler head in the area. Use the Sprinkler Perormance
Charts in the Hunter Product Catalog.
3. Add up all o those numbers and divide the sum by the
total GPM (system design capacity) available.
4. I the total number o zones is not a whole number, roundthe number up to establish how many zones there will be
(1.2 zones becomes 2 zones). This is the total number o
valves needed or the sprinklers in that area.
5. Now that you know how many zones the area will have,
divide up the sprinklers so that each zone in the area will
have approximately the same GPM. Do not place too
many heads on the same zone; stay within the systems
design capacity.
6. Draw and label the zone valves or this area, i.e. Zone 1,
Zone 2, etc.
7. Repeat steps D and E or all areas.

Valves and Pipe
la vas ad Si Pips
F. Locate Valves Layout and Size Pipes
Every zone on the plot plan must have its own valve. The valve
controls the on-o fow o water to a sprinkler zone. Indicate onecontrol valve or each zone and then group the valves together in
an assembly called a valve maniold.
Determine where you want the valve maniold or each area. You
may want a maniold in the ront yard and one in the back yard,
or you may want more locations. Maniold placement is entirely
up to you. We recommend placing the maniold in an accessible
spot or easy maintenance. Place the maniold close to the area
the valves will serve, but where you will not be sprayed when
activating the system manually.
Lateral Lne
The two most common types o pipe used in sprinkler systems
are polyvinyl chloride (PVC) and polyethylene (Poly) Check with
your local Hunter dealer to nd out which type o pipe is used in
your area.
1. Draw a line connecting all o the sprinkler heads in each
separate zone. Follow the example in the illustration on
this page and draw the most direct route with the ewest
turns or changes o direction as possible.
2. Draw a line rom the sprinkler line to the zone valve. This
should be the most direct line possible.
3. Begin sizing the pipe. Start at the head arthest rom the
zone valve. The pipe connecting the last head to the
second to last head should be 3/4."
(See Pipe Sizing Chart.)

4. Add the GPM requirements o those two heads together
to size the next pipe.
5. Add the GPM requirements o the next head to the
previous total.
6. Continue to do this until you get to the zone valve.
Be sure not to size a pipe smaller than the chart indicates.
7. Repeat Steps 1 through 6 or each zone.
Man Lne
1. Determine the location or the system point o connection
(P.O.C.). It should be near the water meter.
2. Draw a line connecting all the maniolds together, and
then draw a line connecting this line to the P.O.C.
3. The main line should be one pipe size larger than the
largest lateral line.
G. Pont O Connecton
Non-Freezng Clmates
Use a brass compression tee to hook your sprinkler system to the
household water supply line. You may hook up to copper, PVC,
or galvanized iron service lines without having to solder or thread
any pipe.
Most areas require some type o backfow preventer to protect
drinking water. Copper pipe may be required between the P.O.C.
and the backfow preventer. Always check the local buildingcode or with the local permitting agency or the requirements in
your area.
Freezng Clmates
I the installation is in a reezing climate and the P.O.C. is in
the basement, install a boiler drain immediately ater the gate
valve to drain the water in the pipe between the P.O.C. and the
backfow preventer in the winter.
Install a slip x slip x 1 inch threaded tee with a riser and a
threaded cap ater the backfow preventer. This will be used when
blowing out the system beore the rst deep reeze o winter.
Revew Desgn
The design process is now complete. Check to make sure you
have placed sprinklers in all areas. Also, review the pipe layout to
be sure you have sized the pipe correctly. You are now ready to
begin installing the system.
P.O.C. Non-Freezing: Use a brass compression tee to
connect your sprinkler system to the household watersupply.
P.O.C. Freezing Climate: I the P.O.C. is in the basement,install a boiler drain immediately ater the gate valve todrain the system beore the rst big reeze.
TiP
Most proessional installers
recommend PVC pipe or the
constant pressure line rom the
backfow preventer to the zone
control valves. Some communities
require copper, however. Check
local ordinances beore laying out
your system.

Mang the Pont o Connecton
1. Reer to the Point O Connection (P.O.C.) detail on the
Sprinkler System Overview (pages 8 - 9).
2. Turn o the water supply to the residence.
3. Dig a hole to expose the supply line.
4. Cut a 1" piece out o the supply line, slip the
compression tee onto the pipe, and tighten the
compression nuts.
5. Install the brass nipple and gate valve.
6. Install the valve box or easy access to the gate valve.
7. Turn the water back on to the residence.
installng the Man Lne
1. Using marking spray paint, indicate the pipe lines rom
the P.O.C. to the valve maniold locations.
2. On existing lawns, lay down a plastic tarp alongside the
marked trench about 2' away rom where the pipe will
be placed.
3. Remove the sod by cutting a strip about 12" wide and
1" to 2" deep using a fat shovel. Roll up the sod and
place the sod and dirt on the plastic tarp.
4. Trenching: Check local codes. I there are no established
local codes or sprinkler main line depth in your area,
trench 10" to 12" deep. Trenching can be done by
hand or with a trencher. Trenchers are available at most
equipment rental yards.
5. Installing Pipe Under a Walkway or Driveway: Hammering
Method: Cap o both ends o a galvanized pipe and
hammer through (See illustration).
Jetting Method: Using a pipe-to-hose threaded adapter,
connect one end o the pipe to a garden hose and
attach a small stream hose nozzle to the other end. Turn
the water on and jet under the concrete.
6. Install the backfow preventer according to local codes.
7. Installing Pipe: Lay out pipe and ttings near the trenches
according to how they will be installed. Be careul not to
get dirt or debris in the pipe.
8. Beginning with the P.O.C. (or backfow preventer i
applicable), measure, cut and install the pipe, working
your way to the last maniold or stub-out. (See Sprinkler
System Overview on pages 8 - 9.)
9. Backlling the main line is discussed on page 12.
Beore trenching, use small fags and marking spray
paint to lay out the irrigation system.
First lay down tarps and remove sod, then dig trenches 10 to12 deep or the main line. Trench 6 to 8 or lateral lines.
Connect pipe under a walk or driveway by capping othe ends o galvanized pipe and hammering through.

installng the Valve Manolds
1. Reer to the valve maniold detail on the Sprinkler
System Overview.2. Maintain at least a 6" clearance between valves or
uture maintenance.
3. Provide a 3" long or longer capped stub-out or
uture additions.
4. Install the valve maniolds onto the main line.
5. Installing the valve boxes is discussed on page 12.
installng the Lateral Lnes
I you can only devote a day or two at a time to installing
this system, and the installation is in an area that is currently
landscaped, lay out all zones and install one zone at a time using
the ollowing steps:
1. Lay Out System: Using the plot plan and small sprinkler
fags, mark the location o the sprinklers and their zone
valve. Make adjustments as necessary or complete
head-to-head coverage. I it appears that you will
need to revise the plan (add a head), recheck the GPM
numbers to make sure you are within the systems design
capacity. (See page 5.) Recheck the Pipe Sizing Chart
to make sure the change will not aect the pipe sizes
designated. (See page 6.)
2. Using marking spray paint, mark the locations or the
lateral lines.3. Trenching: Check local codes. I there are no established
codes or sprinkler lateral line depth in your area, dig
the trenches 6" to 8" deep. I you are installing poly
pipe, you may want to use a pipe puller, which may be
available at your local rental yard.
4. Installing Pipe: Lay out pipe and ttings at the side o
the trenches according to how they will be installed. Be
careul not to get dirt and debris inside the pipe.
5. Backlling the lateral line is discussed on page 12.
Assembling PVC: 1. Placesolvent on inside o ttingand outside o pipe.
Assembling Poly Pipe:1. Place clamp over pipe,then insert barb tting.
PVC: 2. Slip pipe into ttingand wipe o excess solvent.
Poly Pipe: 2. Tighten clamparound pipe and tting.
Automatic Drain Valve Installation or Freezing Climates:Locate the drain valves at the low points in each zone.
Lay out the pipes and sprinklers near the trenches where theywill be installed.
TiP
Use pipe cutters to cut your PVC
sprinkler pipe. Any plastic burrs let
behind when using a hacksaw can
clog up your sprinkler heads. When
using pipe cutters, turn the PVC
pipe 1/8 to 1/4 turn while applying
pressure with the cutters. This
reduces the risk o breaking the PVC.

installng the Controller
1. Decide where you would like to locate the controller.
Most residential controllers should be installed indoors,
i.e. the garage. Follow the installation instructions that
come with the controller. You will need a 115V electrical
outlet to plug in the low voltage transormer.
2. Use color-coded irrigation wire to connect the valves to
the controller. The total number o wires you need is one
or each o the valves, plus one common wire. I you are
wiring a 5-zone system, purchase a combination o wires
with at least 6 total wires long enough to reach rom
your controller to the arthest valve.
3. Installing Wire: Lay the wire in the trench rom the
controller to the valve maniolds. It is best to protect the
wire rom uture digging by installing it directly beneath
the pipe where possible. Leave an expansion loop o
wire at each change o direction. The loop will ensure
that the wires will not be installed too tightly and will
reduce the possibility o stretching.
4. Connect the wires to the valves with waterproo
connectors. You will need one wire or each valve, plus
one common wire which will be connected to one o the
wires on all o the valves.
installng Heads
1. Install all the heads but the last head on a run. Leave thelast one(s) o or proper fushing.
2. Flushing System: Turn on the zone manually at the valve.
Allow the water to fush out any dirt which may have
entered the system. Flush the system even i you are sure
nothing got in during installation. When you are certain
that the water is clean, turn the zone valve o and install
the remaining heads.
3. Checking or Proper Coverage: Turn the zone on at the
controller. By activating the controller, you are making
sure that the wire and wire connectors are operating
properly. Adjust the sprinklers and check or coverage.
Bacfllng
1. Do not directly bury the valves. Install a valve box or
easy access to valves. Wait until you are backlling the
trench to set the valve box.
2. Make sure there are no rocks directly next to the pipe.
Backll one-third to one-hal o the depth o the trench
at a time, compacting the dirt as you go. Make sure
to allow or the extra dirt on the sod when setting the
sprinkler heads and valve boxes.

Ram Remte Ctr KitThe Hunter Roam RemoteControl Kit saves time duringinstallation and routine systemmaintenance. The receiver(let) plugs into the ControllerConnection Kit and thetransmitter (above) activatesthe sprinklers within a 1000range. The user can manuallyrun any zone without resettingthe controller.
TiP
When deciding how many sprinkler
wires you need, add at least two
extra wires or each valve maniold
or uture expansion. It is much
easier to install them now than
later ater the landscape has grown
back in.
Use color-coded irrigation wire to connect the valves to the

Using the plot plan and the check lists below, do a take-o to
determine your Materials List. I you are unsure what a part is
called, check the Sprinkler System Overview. Use colored pencils
and as you count or measure each component, mark the plan andwrite the item down here on this Materials List. Make sure to list
everything on your plan.
1. Point o Connection: Detail and list the materials needed
by size. Check the backfow prevention requirements or
your area and record the materials needed.
2. Pipe: Measure and list pipe by size. Be sure to add a little
additional pipe or waste. Count and list the number o
main line and lateral line ttings by size and type.

3. Control Valves: Count the number o valves by size.
Using the valve detail, list the materials needed.
4. Controller: The number o valves will determine the size
o the controller required. You will need one controller
station or each valve. Measure the wire run rom the
controller to the arthest valve. Note: Use color-coded,
multi-conductor low voltage wire. You will need one
wire for each valve, plus one common wire which will be
connected to all of the valves.
Example: On your plot plan, i you need 8" o wire and
your scale is 1" = 10', then you will need 80' o wire (8
x 10' = 80'). Do not orget to add a little extra wire at
the valve so that it makes it easier to work on the wire
connectors, and enough wire to go up the wall to hook
up to the controller.

Never drop PVC pipe. I it is
dropped and hits a rock or concrete
the pipe could shatter and send
tiny sharp pieces fying. Even i the
pipe does not break, it could get a
hairline crack and later burst under
normal water pressure. This can also
happen i the pipe is allowed to slap
together while being carried.

WATERING GUIDELINES
Clay soils, fine particles,absorbs water slowly
Cool, non-arid climates Apply 1" of water per week.Hot, arid climates Apply 2" of water per week.
Program the controller withshorter run times; increase the
number of start time cycles per
day; decrease the number of
water days per week.
Program the controller with
longer run times and fewer start
time cycles per week.
Loam soils, medium-sized
particles, average absorption rate
Sandy soils, larger particles,absorbs water quite rapidly
Program the controller withshorter run times; increase the
number of start time cycles per
day; increase the number of water
days per week.

Applcaton Rates
Watering application rates will vary with dierent types o
plants, soils and climates. New lawn must be kept moist, and
newly-transplanted shrubs must be watered every day or two.Established plants will need deeper, less requent watering. The
ollowing guidelines will get you started.
Waterng Gdelnes
1. Do not operate more than one valve at a time.
2. Water early in the morning when it is least windy and
pressure is the greatest. Early morning watering will
also reduce water evaporation. Watering in the early
evening is not recommended. A lawn is more likely to
get diseases when wet or a long duration, especially
overnight during the summer. Watering on a hot summer
day may also burn the plants.
3. In most areas, lawns require 1" to 2" o water per week
in the hottest months. Hot and arid areas may require
more.
4. Manually activate your system every week or so to make
sure everything is operating correctly. Check and clean
sprinklers to ensure proper unctioning.
Freezng Areas
In reezing climates, turn o the controller, close the main
sprinkler shut-o valve, drain all the water rom the system,
and blow any remaining water out o the system beore therst reeze. I you are unamiliar with the correct procedure or
blowing out a sprinkler system, contact your local Hunter dealer
or assistance or a reerral.
Choosng Sprnler Nozzles
When designing an irrigation system, it is important to ensure
that the precipitation (rate at which water is applied) is even over
each zone o coverage. Matched precipitation is accomplished
by selecting the appropriate nozzles, or zoning together
sprinklers with the same precipitation rate. The two criteria to
consider are a sprinklers fow rate and arc o coverage. The
illustration (below) depicts three dierent sprinkler heads withmatched precipitation rates. In each case, one gallon per minute
(GPM) is applied to each quarter circle and precipitation is
thereore matched.
