Planning Your System
Before handling any pipe or sprinkler head, take time to plan your layout. Rushing into installation without a clear design often leads to missed areas, uneven coverage, or costly rework. Start by sketching your yard on graph paper or using free online design tools provided by Orbit.
Measure your lawn, flower beds, and any hardscape features like patios or driveways. Note sun exposure zones since different plants have varying water needs. Group plants with similar requirements into separate irrigation zones to avoid overwatering or underwatering.
Check local building codes and homeowner association rules. Many municipalities require permits for new irrigation systems, especially those connected to potable water supplies. If your area mandates a backflow preventer, factor that into your budget and timeline.
Also, locate existing underground utilities. Call 811 or your local utility marking service at least 48 hours before digging. This prevents dangerous and expensive damage to gas, electric, or cable lines.

Designing the Layout
A successful Orbit sprinkler system begins with smart zoning and head placement. Each zone should cover roughly the same area type—for example, one zone for grass, another for shrubs.
Use the head-to-head coverage method: place sprinklers so the spray from one head reaches the base of the next. This ensures even distribution and eliminates dry spots. Orbit provides spacing charts for their nozzles, which indicate optimal distances based on nozzle size and pressure.
Avoid overspray onto sidewalks, driveways, or buildings. Not only wastes water but can cause erosion or structural issues over time. When designing curves along sidewalks or flower beds, stagger heads slightly to maintain overlap.
Consider future growth of trees and shrubs. Install adjustable heads that allow you to change spray patterns as your landscape matures. Also, leave access points near valves and the controller for easy maintenance.
Installing the Main Shut-Off Valve
The main shut-off valve connects your home’s water supply to the irrigation system. Install it where it’s easily accessible, usually near the water meter or where the supply line exits your house.
Shut off the main water supply first. Cut into the existing pipe using a pipe cutter, then install a ball valve or gate valve using appropriate fittings. Wrap threaded connections with plumber’s tape to ensure a watertight seal.
Install a backflow preventer immediately after the shut-off valve if required by code. This device protects your drinking water from contamination caused by pressure changes in the irrigation system.
Next, attach a pressure regulator if your household pressure exceeds 60 PSI. Too much pressure causes misting, uneven distribution, and premature wear on sprinkler components. Orbit recommends operating pressures between 30 and 50 PSI for most residential applications.
Trenching and Pipe Installation
Proper trenching is critical for both functionality and longevity. Dig trenches 6 to 8 inches deep, wide enough to accommodate your PVC pipe with room for fittings.
Slope the mainline slightly (about 1/4 inch per foot) toward the lowest point in the system. This allows gravity to drain water during winterization and prevents freezing damage in colder climates.
Lay the pipe carefully, avoiding sharp rocks or debris that could puncture it. Use PVC glue and primer on all joints according to manufacturer instructions. Allow joints to cure fully before applying pressure.
For lateral lines feeding individual sprinkler heads, run them parallel to the mainline and connect using tees or elbows. Keep bends gradual to reduce friction loss and maintain consistent flow.
Connecting Supply Lines
Once the main and lateral pipes are laid out, connect them to the control valves. Orbit typically uses a manifold system that houses multiple electric solenoid valves in a single housing unit.
Mount the manifold in a valve box above ground level but below frost line if applicable. Connect each zone’s lateral pipe to its corresponding valve outlet using appropriate fittings.
Seal all threaded connections with Teflon tape or pipe dope. For glued joints, apply primer first, then cement evenly around the joint. Wipe away excess adhesive before it dries.
Double-check alignment and slope before backfilling. Misaligned pipes can restrict water flow or cause pooling in low spots.
Installing Sprinkler Heads
Choose the right type of sprinkler head for each zone. Pop-up spray heads work well for lawns, while rotary nozzles suit larger areas like sports fields.
Install risers or threaded adapters compatible with your chosen heads. Make sure they’re flush with the surrounding soil or turf. Use a level to confirm proper height.
Adjust arc and radius settings according to your landscape plan. Most Orbit heads feature tool-free adjustment mechanisms—simply twist the nozzle collar to change spray pattern.
Space heads evenly to achieve head-to-head coverage. For irregular shapes, use corner or side-strip nozzles to direct water precisely where needed.
Secure each head with a stake or clamp to prevent shifting over time. Check manufacturer specifications for recommended burial depth and installation torque values.
Wiring the Controller
Orbit controllers come pre-programmed with default schedules, but custom programming improves efficiency. Begin by connecting the common wire (usually white) to the COM terminal on the valve manifold.
Run individual zone wires (red, black, yellow, etc.) from each valve to the controller. Strip about 1/2 inch of insulation and insert firmly into the designated terminal slots.
Route wires through conduit or protective tubing where they cross walkways or driveways. Bury them at least 6 inches deep to protect against accidental damage.
At the controller, match wire colors to zone numbers indicated on the panel. Secure connections tightly and label each wire for future reference.
Test continuity with a multimeter before energizing the system. Open circuits or shorts indicate wiring errors that must be corrected before proceeding.
Managing Water Pressure
Water pressure significantly impacts sprinkler performance. High pressure creates fine mist instead of coarse droplets, reducing effective range and increasing evaporation.
Install a pressure regulator either at the main supply or at each zone valve. Orbit offers integrated regulators designed specifically for their systems.
Monitor dynamic pressure during operation using a pressure gauge attached to a test port. Ideal pressure varies by head model—consult the product manual for exact specifications.
If pressure fluctuates widely, consider installing a pressure-reducing valve (PRV) upstream of the irrigation system. This stabilizes flow rates across all zones and extends equipment life.
Testing and Adjusting Zones
After completing mechanical and electrical connections, perform a full system test. Activate each zone manually using the controller or by opening individual valves.
Observe spray patterns closely. Look for gaps in coverage, overspray onto hard surfaces, or heads that fail to pop up completely. Document findings and make adjustments accordingly.
Fine-tune nozzle settings to achieve uniform precipitation rates. Overlap adjacent spray arcs by at least 25% to guarantee even saturation.
Run each zone for 10–15 minutes to flush air from the lines and verify steady flow. Watch for leaks at joints, especially after recent glue work.
Record baseline settings and seasonal adjustments in a maintenance log. This helps track system health and identify trends over time.
Troubleshooting Common Issues
Even well-installed systems encounter occasional problems. Here’s how to diagnose and resolve frequent concerns:
**Low Pressure**: Check for partially closed valves, clogged filters, or broken pipes. Clean debris from nozzles and inspect for kinks in supply lines.
**Uneven Coverage**: Verify head alignment, clean outlet screens, and recalibrate spray patterns. Replace worn nozzles showing signs of deterioration.
**Valve Won’t Open/Close**: Test solenoid resistance with a multimeter. Replace faulty coils or clean debris blocking internal passages.
**Controller Malfunction**: Reset the device to factory defaults and reprogram settings. Ensure firmware updates are current for optimal reliability.
**Freezing Damage**: Drain the system before winter or install automatic drain valves. Insulate exposed piping in unheated spaces.
Maintenance Best Practices
Regular upkeep keeps your Orbit sprinkler system running efficiently for years. Schedule monthly inspections during peak growing seasons.
Clean filter screens monthly to prevent clogging from sediment or mineral buildup. Remove trapped particles gently with a soft brush or compressed air.
Inspect sprinkler heads quarterly for cracks, misalignment, or worn seals. Replace damaged units promptly to preserve coverage integrity.
Flush the entire system annually by removing end caps and running water until it runs clear. This clears accumulated silt and debris from pipes.
Winterize systems in freezing climates before temperatures drop below 32°F. Use compressed air to blow out residual water from lines and valves.
Update the controller schedule seasonally to match changing weather conditions and plant water demands.
Additional Tips and Best Practices
Water Conservation Strategies
Install rain sensors or soil moisture probes to skip watering cycles when natural precipitation suffices. These devices integrate seamlessly with most Orbit controllers.
Group plants with similar water needs into dedicated zones. Avoid mixing drought-tolerant species with thirsty vegetation in the same circuit.
Water early morning hours to minimize evaporation losses and reduce disease risk associated with overnight dampness.
Leverage Smart Technology
Modern Orbit controllers support Wi-Fi connectivity and smartphone apps. Receive real-time alerts about leaks, schedule changes, or weather-based adjustments.
Sync your system with local weather services to automatically modify watering duration based on temperature, humidity, and forecasted rainfall.
Track historical usage data to optimize efficiency and justify conservation efforts to stakeholders.
Know When to Call a Pro
Complex retrofits, large properties, or commercial installations benefit from certified irrigation technicians. They bring specialized knowledge of hydraulic calculations and advanced troubleshooting techniques.
However, routine maintenance tasks like replacing nozzles or adjusting timers fall comfortably within DIY territory.
Common Mistakes to Avoid
Skipping Detailed Planning
Installing without a written layout plan often results in poor coverage, redundant zones, or incompatible components. Always draft a scaled diagram before purchasing materials.
Neglecting Pressure Management
High water pressure damages seals, voids warranties, and wastes resources. Invest in pressure regulation upfront rather than dealing with repeated failures later.
Incorrect Backfilling Techniques
Compacting soil too aggressively around pipes causes stress fractures. Use loose-fill sand beneath and around PVC to cushion movement.
Failing to Locate Utilities
Digging without calling 811 risks striking buried cables or gas lines. Always request utility marks before trenching begins.
Overwatering New Lawns
New grass requires frequent light watering, but established turf thrives on infrequent deep irrigation. Adjust schedules as root systems mature.
