What Is an Orbit Sprinkler System?

An Orbit sprinkler system is an automated irrigation solution designed to water lawns, gardens, and landscapes evenly and efficiently. Orbit, a well-known brand in the irrigation industry, offers a wide range of sprinkler kits, pop-up heads, rotors, and drip systems that cater to different property sizes and watering needs. These systems connect to your existing outdoor faucet or water supply and are controlled by a programmable timer, allowing you to set specific watering schedules without manual intervention.

Unlike portable sprinklers that need to be moved and adjusted constantly, an Orbit sprinkler system stays in place and operates automatically. This consistency is what makes it such a valuable investment for homeowners who want healthy turf and vibrant gardens year after year. The systems are engineered to handle various pressure levels and can be expanded as your landscape grows or changes over time.

Benefits of Installing an Orbit Sprinkler System

There are several compelling reasons to invest in an Orbit sprinkler system rather than relying on handheld hoses or portable sprinklers.

• Water Efficiency: Modern Orbit systems are designed to minimize waste. Pop-up heads and rotors deliver water directly to the root zone, reducing overspray on driveways and sidewalks.
• Time Savings: Once programmed, the system waters your lawn on autopilot. You no longer need to drag hoses around or stand outside monitoring sprinkler performance.
• Even Coverage: Orbit sprinkler heads are engineered to distribute water uniformly across large areas, eliminating dry spots that plague manual watering methods.
• Property Value: A professionally installed irrigation system enhances curb appeal and can increase your home’s resale value.
• Flexibility: Orbit offers modular components that let you expand or reconfigure your system as your landscaping evolves.

Tools and Materials You Will Need

Before you begin, gather everything you need to complete the job without unnecessary delays. Having all tools and materials on hand ensures a smooth workflow and prevents frustrating mid-project trips to the hardware store.

Essential Tools

• Shovel and trenching shovel
• Pipe cutter or hacksaw
• Screwdriver and adjustable wrench
• Tape measure
• String line and stakes
• Level
• Drill with appropriate bits
• PVC primer and cement

Materials List

• Orbit sprinkler kit (heads, controller, valves as needed)
• PVC pipes and fittings (schedule 40 PVC is standard)
• Polyethylene tubing for drip zones, if applicable
• Teflon tape
• Electrical wire for controller connections
• Gravel for trench backfill
• Waterproof junction boxes

Planning Your Sprinkler Layout

Planning is arguably the most important phase of the entire project. A poorly planned layout leads to uneven watering, wasted water, and frustration. Start by walking your property and sketching a rough map of your lawn, garden beds, slopes, and any hardscape features like driveways or patios.

Next, determine how many zones your property needs. A zone is a section of your lawn that operates independently, controlled by its own valve. You may need separate zones for sunny areas, shaded areas, slopes, and garden beds because each has different water requirements. Consider water pressure and flow rate as well. Contact your local water utility or use a pressure gauge to measure the static pressure at your outdoor faucet, typically measured in PSI (pounds per square inch). Most Orbit systems operate effectively within a range of 30 to 65 PSI.

Mark the locations of your sprinkler heads on the map using stakes and string. Space them so that the spray from adjacent heads overlaps slightly, ensuring complete coverage with no gaps. This concept is called head-to-head coverage, and it is the foundation of an efficient irrigation design.

Step-by-Step Installation Guide

Now that you have a solid plan, it is time to start the physical installation. Follow these steps carefully for the best results.

Step 1: Trench the Main Water Line

Using a trenching shovel, dig a trench from your water source to the location of your first valve box. The trench should be at least 12 inches deep for main lines and 6 to 8 inches deep for lateral lines, depending on your local frost line requirements. In colder climates, deeper trenches prevent pipe damage from freezing.

Step 2: Install the Main PVC Pipe

Cut PVC pipe to the appropriate lengths and connect the pieces using PVC primer and cement. Run the main line from the water source through the trench to the first valve. Make sure all connections are tight and properly seated. Use a level to ensure the pipe maintains a slight downward slope from the water source, promoting proper drainage when the system is shut off.

Step 3: Install the Valves

At each valve location, install a valve box and connect the valve to the main line. Orbit valves typically come with threaded connections that pair with standard PVC fittings. Apply Teflon tape to all threaded connections to prevent leaks. Position the valve boxes so that the lids sit flush with the ground level.

Step 4: Run Lateral Lines to Sprinkler Heads

From each valve, run lateral PVC pipes to the designated sprinkler head locations. Dig trenches to the appropriate depth, lay the pipe, and secure all fittings. Leave enough pipe extending above ground at each head location to connect the sprinkler riser.

Step 5: Attach Sprinkler Heads

Screw or clip the Orbit sprinkler heads onto the risers. Adjust the spray angle and radius according to the manufacturer’s instructions. Pop-up heads should sit flush with the ground when not in operation. Rotor heads need to be oriented so that the spray pattern covers the intended area.

Step 6: Backfill and Compact

Fill the trenches with soil and gravel as needed. Compact the soil to prevent settling. Avoid stepping directly on freshly laid pipes during this process.

Step 7: Connect Wiring to the Controller

Run low-voltage electrical wire from each valve to the controller location. Connect the wires to the correct terminals on the valves and then to the controller. Follow the wiring diagram included with your Orbit system carefully. A typical connection involves two wires per valve, with the common wire connecting all valves together.

How to Connect the Controller

The controller is the brain of your irrigation system. Orbit offers both mechanical and digital controllers, with digital models providing more advanced programming options. To set up your controller, mount it on a wall near your outdoor faucet, ideally in a sheltered location. Connect the incoming water supply line and the wiring from the valves.

Once mounted, program your watering schedule based on your lawn type, season, and local water restrictions. Most Orbit controllers allow you to set different programs for different zones, specifying start times, run durations, and days of operation. A general guideline is to water lawns deeply two to three times per week rather than lightly every day. This encourages deeper root growth and more drought-resistant turf.

Setting Up Zones and Valves

Zoning is essential for managing different water needs across your property. As mentioned earlier, sunny slopes, shaded areas, and planted beds each require different watering schedules and durations. Each zone operates through its own valve, which the controller activates independently.

When setting up zones, group sprinkler heads with similar water requirements together. Avoid placing a zone of pop-up sprinklers on a slope in the same zone as a flat garden bed, because the slope will drain water faster and require longer run times that could drown the garden plants. Use Orbit’s flow control valves to fine-tune the water delivery to each zone, ensuring balanced performance across the entire system.

Orbit Sprinkler System Types Compared

Orbit manufactures several types of sprinkler systems, each designed for specific applications. Understanding the differences helps you choose the right product for your property.

Choosing the right type depends on your landscape layout, water pressure, and specific watering goals. Many homeowners use a combination of types across different zones for optimal results.

Tips and Best Practices

• Test before finalizing: Turn on each zone before backfilling trenches. This lets you spot leaks and adjust head positions while everything is still accessible.
• Use check valves: Install check valves at low points in the system to prevent drainage from lower sprinkler heads when upper zones are running. This is known as a “check valve” or “anti-siphon” setup and saves significant water.
• Mulch around drip zones: Mulch helps retain moisture in garden beds and reduces evaporation, making your drip irrigation more effective.
• Seasonal adjustments: Reduce watering frequency in spring and fall when evaporation rates are lower. Increase it during peak summer heat.
• Label your wires: When running electrical wire to valves, label each wire at both ends. This makes future troubleshooting or expansion much easier.
• Monitor water bills: An unexpected spike in your water bill often signals a leak in the irrigation system. Investigate promptly to avoid water waste and property damage.

Common Mistakes to Avoid

Even experienced DIYers make errors when installing an Orbit sprinkler system. Being aware of these common pitfalls saves time, money, and frustration.

• Underestimating water pressure: Always measure your water pressure before purchasing components. Installing heads designed for high pressure on a low-pressure system results in poor coverage and uneven watering.
• Skipping the planning phase: Jumping straight into trenching without a detailed layout leads to misaligned heads, inefficient zones, and costly rework.
• Over-tightening fittings: PVC cement sets quickly. Once you push two pieces together, you cannot reposition them. Apply cement carefully and align joints before they set.
• Ignoring local codes: Many municipalities require permits or backflow preventers for irrigation systems. Check with your local building department before starting.
• Poor drainage planning: If your area has heavy clay soil or poor drainage, standing water can accumulate around valves and pipes, causing corrosion and root damage. Add drainage gravel where necessary.
• Neglecting winterization: In freezing climates, failing to blow out the system with compressed air before winter causes pipes and heads to crack. This is one of the most damaging and avoidable mistakes.

Troubleshooting Common Issues

After installation, you may encounter a few issues as the system settles. Here are practical solutions for the most common problems.

• Low water pressure: Check for clogged filters, partially closed valves, or too many heads on a single zone. Reducing the number of heads per zone or installing a pressure regulator can resolve this.
• Uneven watering: Misaligned heads or inconsistent pressure between zones usually cause this. Re-adjust sprinkler angles and check that each zone receives adequate flow.
• Leaking at connections: Tighten or reseal threaded fittings with Teflon tape. For PVC joint leaks, you may need to cut out the faulty section and re-cement a new fitting.
• Controller not activating zones: Verify the wiring connections at both the controller and valve terminals. A loose wire or incorrect terminal assignment is usually the culprit.
• Sprinkler heads not retracting: Dirt or debris can block the retraction mechanism. Remove the head, clean the internal components, and reinstall it carefully.

Maintenance for Long-Term Performance

Regular maintenance keeps your Orbit sprinkler system running efficiently for many years. At a minimum, perform the following tasks each season.

• Inspect all sprinkler heads for damage, clogging, or misalignment.
• Flush the system by opening all zone valves briefly to clear sediment.
• Check the controller batteries and replace them annually.
• Inspect valves for leaks and replace worn diaphragms as needed.
• Adjust watering schedules seasonally to match weather patterns and plant growth stages.
• Before winter, shut off the water supply and blow out the system with compressed air to prevent freeze damage.

Consistent maintenance not only extends the lifespan of the system but also ensures that every dollar you spend on water translates into a healthier, more beautiful landscape.
