    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.

    Curved Areas

    TiP

    Check with local agencies:

    To nd out if a permit is required

    beore installing a sprinkler system.

    To determine where gas, telephone and

    other utility lines are buried.

    To nd out which type of backow

    preventer is required in your area.

    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."

    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.

    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.

    Ss Isaai

    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

    controller. You will need one wire or each valve, plus onecommon wire.

    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.

    Wai gidis

    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
