Conserve Water & Money – Reduce over-watering and water when evaporationlevels are low. Save Time – Enjoy a beautiful yard and spend more time doing the things you like. Increase Property Value – Greener, thicker lawns, shrubs and trees, make your propertymore attractive. Eliminate Yard Clutter – Eliminate the ugly tangle and yellow marks left by unsightlygarden hose.CHECK LOCAL CODES2Water DistrictCall your local water district for requirements concerning permits, plumbers, backflow preventionand pipe requirements.2Sprinkler System Layout & Installation Guide

Water flow is measured in gallons per minuteor GPM.Measure Your Water Pressure Attach an Orbit pressure gauge (part #53020, 91130) to an unregulated outsidefaucet*. Unregulated means a line withouta pressure regulator.180160140200020Orbit120psi100 80 Open the faucet and record the readingon the gauge. No water should be runningduring the sure the Main Water Service Line Wrap a piece of string around your mainwater service line then measure the lengthof the string. Use the table to convert the string lengthto pipe size (diameter).Note: The main water service line is the pipe that runs fromthe water meter to the house. If you're connecting to a lineother than the main line, measure the line that you will beconnecting to.DETERMINE SIZE OF SERVICE LINELength of string2"2-3/4"Copper pipe size1/2"3/4"PVC or galvanized pipe size1/2"3-1/4"3-1/2"4-1/4"1"3/4"Pipe Size1"System CapacityWATER PRESSURE (PSI)MAINLINESIZE35 LB. 40 LB. 45 LB. 50 LB. 55 LB. 60 LB. 65 LB. 70 LB. 75 5 15.07.07.58.09.013.0 14.015.016.0 17.516.018.520.017.59.5Use the mainline pipe sizeand pressure(PSI) taken todetermine thegallons perminute (GPM)capacity of yoursystem.21.0GPM Capacity* If an unregulated faucet is unavailable, call the local water district for an estimated PSI.Important: If your water pressure exceeds 80 PSI, use a pressure reducer.

07WTM003045 53251-01 rE.qxd3/2/072:30 PMPage 7Planning & Design6PLAN HEAD PLACEMENTHead to Head CoverageProper sprinkler placement allows even watering andreduces dry patches.Proper placement requires: Head to head coverage: Each sprinkler should sprayto the head beside and across it. Equal spacing between heads: Permits uniform waterdistribution.Placement Example: Good Good Overlap Head to head coveragePlacement Example: BadThere is not enough overlap. The center is notgetting water. Not enough overlap No coverage in centerSidewalkNarrow StripsOn narrow strips of grass use strip patternspray heads and space them evenly apart.These heads may be used for narrowstrips up to 4 feet wide.Evenly space strip heads on narrow sections.Place Heads in Corners Begin by placing a sprinkler ineach corner on your drawing. Use a compass to draw thespray pattern.Note: Use chart 2 on page 20 to obtain spraydistance.Sprinkler System Layout & Installation Guide7
07WTM003045 53251-01 rE.qxd3/2/072:30 PMPage 8Planning & DesignAdd Heads andAdjust Spacing Add sprinklers alongthe sides or center toincrease coverage.7CREATING WATERING ZONES OR STATIONSA watering zone or station consists of a group of sprinklers attached to one valve.The number of heads per zone will be determined in this section.Purpose of ZonesZones are designed to: Maintain adequate water flow for optimal spray coverage (Avoid dry patches) Separate areas based on watering requirements- Shade vs. Full Sun Areas- Lawn vs. ShrubsImportant: Do not mix sprinkler types in the same zone (e.g. Gear Drive, Impacts, Pop-Ups and Bubblers) Do not exceed the maximum sprinkler heads recommended per zone Use the recommended pipe size in this guide. Smaller diameter pipe will decrease the water flow.Group Heads of Same Type in the Same AreaStarting with large area heads, use the followingexample as a guide. Identify all large area heads onyour drawing.Divide Large Area Heads into ZonesSTEP 1: Maximum Heads Per ZoneLargeUse the following information (collected earlier) todetermine zone capacity: Main Line Size Water Pressure (PSI) Large area head selectedUse Orbit’s Quick Reference (Chart 1, Page 20)to determine the maximum heads per zone for yoursprinkler system.Large area heads circled8Sprinkler System Layout & Installation Guide

Based onthis information, and using the QuickReference, we see that we cannot usemore than three Voyager II sprinklers inthe same zone.STEP 2: Identifying Sprinklers in a ZoneBegin grouping large area heads, ensure you do not exceed your “Maximum Heads per zone number.”Example – Since we determined (in our example above) that 3 Voyager II headsis the maximum zone capacity, we grouped all large area heads into 2 zones.Step 3: Medium and Small Area Head ZonesRepeat steps 1 & 2 to determine and identify zones for Medium Areas Heads. Repeat again forSmall Area Heads.Step 4: Number Each Zone Assign a number to each zone.Sprinkler System Layout & Installation Guide9
07WTM003045 53251-01 rE.qxd3/2/072:30 PMPage 10Planning & Design8PLAN VALVE PLACEMENTYou'll need to select a location for your main shut-off valve and the best location for thesprinkler valve manifold.Main Shut-Off ValveThe Main Sprinkler Shut-Off valve is the valve that shuts off water to the entire sprinklersystem. Connection to the main water supply is “downstream” of your water meter. Markthe location on your plan.FRONTVALVEMANIFOLDWATERMETERMAIN LINE TOREAR MANIFOLDMAIN LINEMAIN SPRINKLERSHUT-OFF VALVETO HOUSEWATER METERValve Manifold LocationOne valve will be used for each zone. Valves that are grouped together are called a manifold.It’s common to install one manifold in the front yard and one in back.Mark the Location on Your PlanTip: The valve manifold(s) should be installed in an accessible location, away from heavy foot traffic, where it is easy to operateand service. It's also a good idea to locate the manifold on elevated ground, to avoid water accumulating around the valves.Plan Backflow PreventionA backflow prevention device is used to stop foreign material from siphoning back into themain water supply. The local code information you gathered from your water district shouldinclude the type of device to install and where and how it should be installed. Plan a locationfor your backflow prevention device and draw it on your layout.Three common typesDouble CheckPressure Vacuum BreakerAutomatic Anti-Siphon ValveNote: For certain Canadian areas Dual Check Valves are used10Sprinkler System Layout & Installation Guide
07WTM003045 53251-01 rE.qxd3/2/072:30 PMPage 11Planning & Design9DIAGRAM PIPE LAYOUTYou need to plan and draw the layout for your main sprinkler line and lines for each zone.Main Sprinkler LineDraw the MainSprinkler LineRouteUse a direct routeto draw the mainsprinkler line fromthe main shut-offvalve to the frontand back yardmanifolds.Important: Your mainsprinkler line should be1 size larger than thewater main supply line.Header and Lateral Lines GuidelinesHeader lines – Attaches to a valve and supplies water to the lateral lines Do not use pipe smaller than 1" Do not attach sprinklers to this lineLateral lines – Pipe that branches off from the header line and supply water to the sprinkler heads Do not use pipe smaller than 3/4"Good Layout ExampleThis is a good layout because the water is evenly distributedbetween the lateral lines and individual sprinklers.LateralHeaderBad Layout ExampleThis is a bad layout because there is no header line. Thesprinkler heads, located at the end of the line, will have lesswater pressure than the heads located closer to the valve.Sprinkler System Layout & Installation Guide11
07WTM003045 53251-01 rE.qxd3/2/072:30 PMPage 12Planning & DesignHeader LineDraw a header line from the manifold to each zone. Header lines willbe intersected with lateral lines.Sprinkler heads should not beinstalled on this line.Use 1" PipeLateral LinesDraw lateral lines that connect theheader line to sprinkler heads.These lines should be branching,not circular.Use 3/4" pipe10PLAN TIMER LOCATIONSelect a location near a power source and where it's easy to access. You'll need to be able torun sprinkler wire to each valve.

Both types are easy touse, but they are assembled differently. Read about each type below to make your selection.Working with PVC Pipe Using an Orbit cutting tool, cut pipe to length and cleanthe end. Apply PVC primer and PVC cement, using instructionsprovided. Insert pipe into fitting.Working with Polyethylene Pipe Using an Orbit cutting tool, cut poly-pipe to length. Slide a stainless steel clamp over the end of the pipe. Insert a barbed fitting into the pipe. Tighten the clamp over the pipe and fitting.Warning: Poly pipe should not be used for the main line to the manifold.Sprinkler System Layout & Installation Guide15

Just plug in the valvejack into the water-tight Snap-Wire housing and insertsprinkler wire into the other side. No confusing wiring ormessy grease caps (see page 22 for more info).Run Sprinkler Wires to TimerMost often you can use an existing sprinkler pipe trench to run your sprinkler wire.
