Why Replace Hunter Sprinkler Heads?

Over time, sprinkler heads are exposed to constant water pressure, UV radiation from sunlight, foot traffic, and debris from lawns and gardens. These factors can cause a variety of issues that compromise the performance of your irrigation system. A cracked housing may allow water to leak out at the base instead of being directed through the nozzle. A clogged or worn nozzle can result in uneven coverage, leaving patches of your lawn dry while overwatering others. In some cases, the internal spring mechanism that lifts the riser tube can fail, preventing the head from popping up at all.

Replacing a sprinkler head is not only about fixing visible damage. Sometimes a head may appear intact but still underperform due to mineral buildup inside the nozzle or gradual wear to the internal components. Upgrading to a newer model with improved features, such as pressure regulation or more efficient nozzles, can also enhance the overall effectiveness of your irrigation system. Regular replacement of sprinkler heads as part of a preventive maintenance routine helps ensure that your lawn receives consistent and appropriate watering, which promotes healthy growth and reduces water waste.

Tools and Materials You Will Need

Before you begin the replacement process, gather all the necessary tools and materials to avoid interruptions midway through the job. Having everything ready will make the task faster and more efficient. Here is a list of what you should have on hand:

• Water shut-off tool or flat-head screwdriver: Used to turn off the water supply to the zone containing the sprinkler head you are replacing.
• Adjustable wrench or channel-lock pliers: Helpful for gripping and turning the sprinkler head, especially if it is stuck or corroded.
• Shrub or sprinkler head wrench: Some Hunter models come with a specialized wrench that fits into the top of the head for easier removal. Check your model number to see if one is available.
• Teflon tape or pipe sealant: Applied to the threaded riser to ensure a watertight seal when installing the new sprinkler head.
• Towels or rags: Useful for wiping away dirt, debris, and excess water from the riser and surrounding area.
• Bucket or small container: Place this beneath the riser to catch any residual water that may drain out when you remove the old head.
• New Hunter sprinkler head: Make sure it is compatible with your existing system in terms of thread type and connection size.
• Garden gloves: Protect your hands from dirt, sharp edges, and potentially harmful chemicals in older irrigation systems.

Types of Hunter Sprinkler Heads

Hunter Industries manufactures a wide range of sprinkler heads designed for different applications and irrigation needs. Understanding the type of head you currently have installed will help you choose the right replacement and ensure compatibility with your system. The main categories include:

Pop-Up Spray Heads

These are the most common residential sprinkler heads. They are installed below ground level and rise up on a riser tube when water pressure is applied. Pop-up spray heads typically have a fixed spray pattern, such as full circle, half circle, or quarter circle, and are ideal for small to medium-sized areas. They are available in various heights and inlet sizes to accommodate different installation requirements.

Rotary Sprinklers

Hunter rotary sprinklers, such as the PGP series, deliver water through a rotating stream rather than a fixed spray. This method provides more even coverage over larger areas and is less susceptible to wind drift. Rotary sprinklers are often used in commercial landscapes and golf courses but are also suitable for large residential properties.

MP Rotators

MP Rotator sprinkler heads use multi-stream rotating nozzles that deliver water in a slow, steady stream. This approach reduces runoff and allows water to soak into the soil more effectively. MP Rotators are popular for their water efficiency and ability to be mixed with traditional spray heads within the same zone.

Pressure-Compensating Heads

These heads maintain a consistent outlet pressure regardless of fluctuations in supply pressure. This feature prevents misting and fogging, which can occur when water pressure is too high. Pressure-compensating heads are particularly useful in systems where elevation changes or long pipe runs cause pressure variations.

Shutting Off the Water Supply

The first and most critical step in replacing a sprinkler head is shutting off the water supply to that specific zone. Attempting to remove or install a sprinkler head while water is flowing will result in a messy and potentially dangerous situation. Most Hunter irrigation systems are divided into zones, each controlled by an electric solenoid valve. To shut off the water to a particular zone, follow these steps:

1. Locate the zone valve: The valve box is typically found near the area being watered. It is usually a small, rectangular box with a lid that can be lifted or unscrewed. Inside, you will find the solenoid valve and associated wiring.
2. Turn off the valve: Use a flat-head screwdriver to turn the solenoid (the cylindrical component on top of the valve) clockwise until it stops. This action closes the valve and stops water flow to that zone.
3. Verify the water is off: Return to the sprinkler head you intend to replace and manually turn on the zone using your irrigation controller. The head should not activate, confirming that the water supply has been successfully shut off.
4. Relieve residual pressure: Even after shutting off the main valve, some water may remain in the pipes. Turn the sprinkler head slightly counterclockwise to allow any trapped water to drain out before proceeding with removal.

If your system does not have individual zone valves, you may need to shut off the main water supply to the entire irrigation system. In this case, all zones will be affected, so plan accordingly if other areas of your landscape require watering.

Removing the Old Sprinkler Head

With the water supply turned off, you can now safely remove the old sprinkler head. The removal process varies slightly depending on the model and installation method, but the general approach remains consistent. Follow these steps to remove the old head:

1. Clear the area: Remove any grass clippings, dirt, or debris that may be surrounding the sprinkler head. This will give you better access and prevent foreign material from falling into the riser pipe during removal.
2. Identify the connection type: Most Hunter sprinkler heads are attached to a threaded riser pipe that extends from the underground supply line. Some models may have a compression fitting or a quick-connect coupling. Knowing the connection type will help you choose the right removal technique.
3. Use the appropriate tool: For standard threaded connections, an adjustable wrench or channel-lock pliers works well. Grip the body of the sprinkler head firmly and turn it counterclockwise to loosen it from the riser. If the head is stuck, apply penetrating oil and allow it to sit for several minutes before attempting removal again.
4. Handle the riser carefully: Once the old head is removed, inspect the riser pipe for any signs of damage, such as cracks, corrosion, or mineral buildup. The riser should be clean and in good condition to ensure a proper seal with the new head.
5. Clean the threads: If the riser has threaded connections, use a wire brush or old cloth to clean away any old Teflon tape, sealant, or debris from the threads. Damaged or dirty threads can lead to leaks or difficulty installing the new head.

In some cases, the sprinkler head may be so tightly seized that it cannot be removed by hand or with standard tools. If this happens, try using a specialized sprinkler head removal tool or applying heat from a hair dryer to expand the metal and break the bond. As a last resort, you may need to dig around the riser to gain better access or replace the entire riser assembly if it is damaged beyond repair.

Preparing the Riser and Threads

After removing the old sprinkler head, take the time to properly prepare the riser and its threads before installing the new head. This step is crucial for preventing leaks and ensuring a secure connection. Here is how to prepare the riser:

1. Inspect the riser: Check the riser pipe for any cracks, corrosion, or deformities. If the riser is damaged, it should be replaced along with the sprinkler head. A compromised riser can lead to persistent leaks even with a new head installed correctly.
2. Clean the threads: Use a wire brush, sandpaper, or an old toothbrush to remove any old Teflon tape, pipe dope, or mineral deposits from the threaded portion of the riser. Clean threads ensure proper engagement with the new head and prevent cross-threading.
3. Check the thread size: Hunter sprinkler heads come in various thread sizes, commonly ¾ inch or 1 inch NPT (National Pipe Thread). Verify that the thread size of your new head matches the riser. Using a mismatched size can result in leaks or damage to the threads.
4. Apply Teflon tape or sealant: Wrap the male threads of the riser with Teflon tape in a clockwise direction, starting from the end of the pipe. Apply 2-3 wraps, ensuring the tape lies flat against the threads without overlapping or bunching. Alternatively, you can use a pipe thread sealant, which provides a more robust seal in high-pressure applications. Be careful not to over-tighten the new head, as this can damage the threads or crack the housing.

If your system uses a compression fitting instead of threaded connections, the preparation steps differ. In this case, inspect the compression nut and O-ring for wear or damage. Replace these components if necessary, and ensure the fitting is clean and free of debris before reassembling.

Installing the New Sprinkler Head

With the riser prepared, you can now install the new Hunter sprinkler head. Proper installation ensures optimal performance and prevents leaks or other issues. Follow these steps to install the new head:

1. Align the threads: Carefully position the new sprinkler head over the riser, ensuring the threads are properly aligned. Cross-threading can damage both the head and the riser, so take your time to start the connection by hand.
2. Hand-tighten first: Begin threading the head onto the riser by turning it clockwise with your hand. This helps prevent cross-threading and ensures the connection starts smoothly.
3. Use a wrench for final tightening: Once the head is hand-tight, use an adjustable wrench or channel-lock pliers to give it an additional 1-2 full turns. Be careful not to over-tighten, as this can strip the threads or crack the head housing.
4. Check for alignment: Ensure the head is positioned correctly and sits flush with the surrounding grade. If the head is tilted or uneven, loosen it slightly and reposition it before retightening.
5. Secure the area: Backfill any soil or mulch that was removed during the process, gently tamping it down to create a stable base around the head. Avoid placing excessive pressure on the head itself, which could cause it to shift out of position.

For pop-up spray heads, make sure the riser tube extends to the appropriate height above the nozzle. If the riser is too short, the head may not pop up fully, resulting in poor coverage. Conversely, if the riser is too long, the head may extend too far above the ground, making it vulnerable to damage from mowers and foot traffic.

Adjusting the Spray Pattern and Distance

Once the new sprinkler head is installed, you will need to adjust its spray pattern and throw distance to match the specifications of your irrigation system. Proper adjustment ensures even water distribution and prevents overspray onto sidewalks, driveways, or buildings. Here is how to adjust your new Hunter sprinkler head:

1. Consult the manual: Refer to the installation and adjustment instructions provided by Hunter for your specific model. Each head may have unique adjustment mechanisms and recommended settings.
2. Set the spray pattern: Most Hunter spray heads have a fixed spray pattern, such as full circle, half circle, or quarter circle. If your head has an adjustable pattern, rotate the nozzle or use the adjustment key to set the desired arc. Ensure the pattern aligns with the area you want to water.
3. Adjust the throw distance: The throw distance determines how far the water travels from the head. Use the radius adjustment screw (usually located on top of the nozzle) to increase or decrease the distance. Turn the screw clockwise to reduce the throw and counterclockwise to increase it. Test the adjustment by observing the spray pattern.
4. Check for uniformity: Walk around the watering area and observe the spray pattern. Look for dry spots, overspray, or areas receiving too much water. Make additional adjustments as needed to achieve even coverage.
5. Lock the settings: Once you are satisfied with the adjustments, ensure all screws and locking mechanisms are securely tightened. Some heads have a locking tab or clip that prevents accidental changes to the settings.

For rotary sprinklers and MP Rotators, the adjustment process may involve setting the rotation arc, change-over point, and arc radius. These heads typically require a flat-head screwdriver or a specialized adjustment tool. Take care to follow the manufacturer’s instructions precisely, as incorrect adjustments can lead to inefficient watering and potential damage to the internal components.

Testing the System

After installing and adjusting the new sprinkler head, it is essential to test the system to verify that everything is functioning correctly. This step helps identify any issues before they become more serious problems. Here is how to test your newly replaced sprinkler head:

1. Restore water supply: Turn the zone valve counterclockwise to reopen the water supply. If you shut off the main water supply, turn it back on gradually to avoid sudden pressure surges.
2. Activate the zone: Use your irrigation controller to start the zone containing the replaced sprinkler head. Allow the system to run for several minutes to build up pressure and flush out any debris that may have entered the pipes during the replacement process.
3. Observe the head: Check that the new sprinkler head pops up fully and sprays water evenly according to the adjusted pattern. Look for any signs of leaking around the base, which may indicate improper installation or damaged threads.
4. Check neighboring heads: Pay attention to the performance of adjacent sprinkler heads in the same zone. If they are now spraying less water or not activating at all, it may be due to reduced system pressure caused by the new head’s flow rate. In this case, you may need to adjust the zone’s overall settings or replace additional heads.
5. Monitor for issues: Let the system run for 10-15 minutes and periodically check for leaks, uneven coverage, or other problems. Make any necessary adjustments to the spray pattern or throw distance based on your observations.

If you notice persistent issues after testing, such as continuous leaking, failure to pop up, or significantly reduced performance, there may be underlying problems with the riser, valve, or piping. In these cases, it is best to consult a professional irrigation technician who can diagnose and resolve more complex issues.

Troubleshooting Common Issues

Even with careful installation and adjustment, you may encounter some common problems when replacing Hunter sprinkler heads. Here are solutions to the most frequently reported issues:

Head Not Popping Up

If the sprinkler head fails to rise from the ground when the zone is activated, the issue is usually related to low water pressure or a mechanical obstruction. Check the following:

• Ensure the zone valve is fully open and supplying adequate pressure.
• Verify that the riser tube is not obstructed by debris or sediment.
• Inspect the internal spring mechanism within the head for damage or breakage.
• Confirm that the head is properly seated on the riser and not cross-threaded.

Water Leaking at the Base

A leak around the base of the sprinkler head typically indicates a poor seal between the head and the riser. Try these fixes:

• Shut off the water and remove the head to inspect the threads for damage.
• Clean the threads thoroughly and reapply Teflon tape or pipe sealant.
• Ensure the head is hand-tightened before using a wrench for final tightening.
• Replace the riser if the threads are stripped or corroded beyond repair.

Uneven Spray Pattern

If the spray appears irregular or uneven, the nozzle may be clogged or misaligned. Address this by:

• Removing the nozzle and cleaning it with a soft brush to eliminate debris.
• Checking that the nozzle is correctly oriented and seated in the head.
• Adjusting the spray pattern according to the manufacturer’s specifications.
• Replacing the nozzle if it is damaged or excessively worn.

Reduced Water Pressure

Low pressure affecting the entire zone may indicate a broader system issue. Investigate the following:

• Check for broken pipes or leaks in the lateral lines supplying the zone.
• Inspect the zone valve diaphragm for tears or blockages.
• Verify that no other zones are operating simultaneously, which can reduce available pressure.
• Consider upgrading to low-flow sprinkler heads if the system pressure is consistently low.

How Often Should You Replace Sprinkler Heads?

The lifespan of a Hunter sprinkler head depends on several factors, including the model, environmental conditions, and frequency of use. Under normal circumstances, most residential sprinkler heads last between five and ten years. However, certain conditions can accelerate wear and necessitate more frequent replacement:

• High water pressure: Consistently operating at pressures above the recommended range can cause premature failure of internal components such as seals and springs.
• Freeze-thaw cycles: In regions with freezing winters, water trapped inside the head can expand when it freezes, cracking the housing or damaging internal mechanisms.
• UV exposure: Prolonged exposure to direct sunlight can degrade plastic components, leading to brittleness and cracking.
• Mechanical damage: Foot traffic, lawn mowers, and garden equipment can physically damage sprinkler heads, requiring replacement even if they are relatively new.
• Mineral buildup: Hard water containing high levels of calcium and magnesium can cause internal components to clog, reducing performance and lifespan.

To maximize the lifespan of your sprinkler heads, perform regular inspections and maintenance. Check for signs of wear such as cracks, leaks, or reduced spray performance. Clean nozzles and filters periodically to remove debris and mineral deposits. Additionally, winterize your irrigation system in cold climates by draining water from the lines and storing removable components indoors during freezing months.

Cost Comparison: DIY vs Professional Replacement

Replacing a Hunter sprinkler head yourself can result in significant cost savings compared to hiring a professional irrigation technician. Here is a breakdown of the typical costs associated with each option:

For a typical residential system with 10-15 sprinkler heads, the total cost of DIY replacement ranges from $100 to $750, while hiring a professional would cost between $1,500 and $4,500.
