Planning Your Lawn Sprinkler System
Before you start installing your Lawn Sprinkler System, proper planning is crucial. Here’s how to get started:
Evaluate Your Yard Size
Understanding the size and layout of your yard is the first step. Measure the dimensions and note any unique features like flower beds, slopes, or shaded areas. This helps in creating an efficient watering plan.
Check Water Pressure and Flow Rate
Water pressure and flow rate are key factors for your system’s performance. You’ll need at least 30 to 35 psi (pounds per square inch) of pressure and about 10 to 13 gpm (gallons per minute) of flow. Use a pressure gauge to measure your water pressure directly from an outdoor faucet. To determine the flow rate, fill a 1-gallon container with water and time how long it takes. Divide the container size by the time in seconds, then multiply by 60 to get gpm.
Custom Design Your System
A custom design ensures that every part of your yard gets the right amount of water. Most irrigation manufacturers provide design guides to help you. Alternatively, you can sketch your property boundaries and mark areas that need watering. This sketch will be your roadmap for laying out zones and selecting sprinkler heads.
Sketching Property Boundaries
Using graph paper, draw your yard to scale (1 inch = 10 feet is a good ratio). Include all permanent features like your house, driveway, sidewalks, and trees. Mark where your water meter is located.
Important Tips:
- Zones: Divide your yard into zones based on plant types and sun exposure. For example, separate lawn areas from flower beds.
- Sprinkler Heads: Choose appropriate sprinkler heads for each zone. Pop-up heads are great for lawns, while taller shrub sprinklers work well for flower beds.
Mapping Out Zones
Zones are independently controlled sections of your sprinkler system. They ensure that each area receives the right amount of water. The number of zones depends on your yard’s physical attributes and your water supply’s capacity.
Steps to Create Zones:
- Measure and Map: Measure your yard and draw it to scale.
- Mark Features: Clearly mark landscape features like shrubs, trees, and slopes.
- Determine Locations: Plan where each sprinkler head will go, ensuring head-to-head coverage to avoid dry spots.
Finalizing Your Plan
Double-check your plan to ensure complete coverage and efficient water use. Make multiple versions if needed. Keep the final version for future reference, especially for maintenance.
With your plan in hand, you’re ready to start gathering materials and tools for your Lawn Sprinkler System Installation. Next, we’ll dive into the tools and materials you’ll need to bring your plan to life.
Gathering Necessary Materials and Tools
Before you can get started with your Lawn Sprinkler System Installation, you’ll need to gather all the essential materials and tools. Here’s a breakdown of what you’ll need:
PVC Pipes
PVC (polyvinyl chloride) pipes are the backbone of most sprinkler systems. They are strong, durable, and easy to work with. You’ll typically use Schedule 40 PVC, which is available in various diameters. The diameter you choose depends on your water pressure and flow rate, but 3/4-inch to 1-inch pipes are common for residential systems.
Fittings
Fittings, such as tees, elbows, and couplings, are necessary for connecting and redirecting pipes. These components help you steer around obstacles and ensure water flows to all parts of your yard. Make sure to use PVC cement to securely connect these fittings to the pipes.
Trenching Machine
A trenching machine can save you a lot of time and effort. Trenches for sprinkler systems are usually 6 to 12 inches deep, which is deep enough to protect the pipes from damage and allow the sprinklers to retract underground. You can rent a trencher from most home improvement stores.
Valve Box
Valve boxes protect your valves and provide easy access for maintenance. They are typically buried just below the surface and house the manifold, which is the master control for your system. Choose a valve box that is large enough to accommodate all your valves and any future expansions.
Timer
A timer, or controller, allows you to automate your watering schedule. Modern timers can be programmed to water different zones at different times, ensuring each area of your yard gets the right amount of water. Some advanced models even include weather sensors to adjust watering based on rainfall and temperature.
Sprinkler Heads
Sprinkler heads come in various styles, each suited to different watering needs. Pop-up heads are great for lawns, while taller shrub sprinklers are ideal for flower beds. Sprinkler heads are rated by the gallons per minute (GPM) they can supply at a specific pressure. Choose heads that match your system’s water pressure and flow rate.
Drip-Irrigation Tubing
Drip-irrigation tubing is used for watering flower beds, shrubs, and other plants that require a more controlled water supply. This tubing delivers water directly to the base of the plants, reducing evaporation and water waste. It’s flexible and can be easily curved around obstacles.
Additional Tools
- Utility Knife: For cutting tubing and pipes.
- Hand Saw or Pipe Cutter: For cutting PVC pipes to the desired length.
- Clamps: For securing polyethylene pipes and fittings.
- Shovel or Ditch Spade: For digging trenches by hand if a trencher is not available.
- Flags or Stakes: For marking the locations of sprinkler heads and zones.
- Pressure Gauge: For measuring water pressure.
With these materials and tools in hand, you’re well on your way to installing your own lawn sprinkler system. Next, we’ll dive into the step-by-step process, starting with marking and digging trenches.
Step-by-Step Installation Guide
Step 1: Marking and Digging Trenches
First, mark the locations of all trenches and sprinkler heads using wooden stakes or plastic flags. This helps you visualize the layout and ensures accurate placement.
Important: Contact your local one-call center to have utilities mark any buried cables, gas lines, or sewer lines. This step is crucial for safety.
Next, use a gas-powered trenching machine to dig trenches. Trenches should be 4 to 12 inches deep, depending on your local recommendations. Most rental dealers offer delivery and pick-up services for trenching machines, which can save you time and effort.
Step 2: Connecting to the Water Source
Turn off the water to your house at the meter. Locate the main water line, which could be in your basement or buried underground.
Cut into the main water line and splice in a tee fitting using PVC cement and primer. If the line is copper, solder on a copper tee. Then, glue a 90-degree PVC elbow onto a male PVC adapter and thread the adapter into the tee fitting on the main water line.
Tip: If you’re uncomfortable with this step, consider hiring a professional plumber to handle the water connection.
Step 3: Installing Zone Valves
Dig a trench from the main water line to the valve box location. At the end of the trench, dig a hole about 18 inches deep and 2 to 3 feet long. Line the hole with 2 inches of gravel and set the valve box into it, ensuring the lid is flush with the grass.
Follow the manufacturer’s directions to glue together the manifold and attach the zone valves. Place the manifold in the valve box. Run a 1-inch schedule 40 PVC pipe from the main water line to a backflow-prevention device, then connect it to the manifold.
Dig a shallow trench from the valve box to the location for the timer. Lay the 24-volt underground wire in the trench and connect it to the wires from each valve.
Step 4: Laying Pipes and Connecting Sprinklers
Following your plan, lay PVC pipes in all the trenches leading from the valve box. Join pipe sections with couplings and PVC cement as needed.
Wherever a pipe branches off to a sprinkler head, splice in tee fittings and attach a short length of flexible piping. This flexible piping will connect to the sprinkler head. For drip-irrigation tubing, attach an upturned elbow, a short vertical pipe, and a pressure reducer with a microfilter.
Tip: Buying PVC fittings in multi-piece contractor packs can save you money and reduce trips to the home center.
Step 5: Flushing and Testing the System
Once all pipes are laid and connected, use 90-degree elbows to join the PVC water pipes in the trenches to the zone valve pipes protruding from the valve box.
Turn on the water to flush any dirt or debris from the system. After flushing, turn off the water to install the sprinklers. Attach a pop-up sprinkler to the end of each length of flexible piping. Remove the cap from the sprinkler and install the appropriate spray nozzle.
Finally, mount the programmable timer on the house wall. Strip the insulation from the ends of the 24-volt wires leading from the zone valves to the timer and attach them to the timer terminals as shown in the manufacturer’s instructions. Run a test to ensure each zone and all sprinklers are operating properly, and adjust any nozzles that are spraying off course.
Now that you’ve completed the installation, your lawn should be evenly watered and well-maintained. Next, let’s address some common questions you might have about Lawn Sprinkler System Installation.
