Toro Super 700 Sprinkler Head Replacement

Understanding the Toro Super 700 Sprinkler Head

The Toro Super 700 sprinkler head is a common component in many residential and commercial irrigation systems. Designed for mid-range coverage, it offers adjustable arc settings and various nozzle options to suit different landscaping needs. Its durability and relatively simple design have contributed to its widespread use.

Before commencing any replacement procedure, identify the specific model of the Super 700 in use. Visual inspection of the head itself will often reveal identifying marks or model numbers. Understanding the specifications, such as flow rate and throw distance, is crucial for selecting the correct replacement. Reviewing existing system documentation, if available, can provide valuable information.

Tools and Materials Required

Replacing a Toro Super 700 sprinkler head typically requires only a few basic tools. A flathead screwdriver is essential for adjusting the arc and removing the nozzle. Pliers may be necessary to grip and loosen stubborn connections. Teflon tape (plumber's tape) is vital for creating a watertight seal on threaded connections. The most critical material is, of course, the replacement Toro Super 700 sprinkler head, ensuring it matches the specifications of the original.

Essential Tools:

• Flathead Screwdriver
• Pliers
• Teflon Tape
• Replacement Toro Super 700 Sprinkler Head

Step-by-Step Replacement Procedure

The replacement process is generally straightforward, but meticulous attention to detail is important to prevent leaks and ensure optimal performance.

Step 1: Shut Off the Water Supply

The first and most important step is to shut off the water supply to the zone containing the sprinkler head being replaced. This is typically done at the zone control valve or the main water supply to the irrigation system. Failure to do so will result in significant water loss and potential damage.

Step 2: Excavate Around the Sprinkler Head

Carefully excavate around the sprinkler head to expose the connection point. Use a small shovel or trowel to avoid damaging the surrounding turf or plants. Expose enough of the connection to allow for easy access and manipulation.

Step 3: Disconnect the Old Sprinkler Head

Using pliers, carefully disconnect the old sprinkler head from the riser. If the connection is threaded, turn the head counterclockwise to loosen it. Be prepared for a small amount of residual water to drain out. If the connection is glued (common in some PVC systems), the pipe will need to be cut, and a coupling installed.

Note: If the threads are corroded or damaged, consider replacing the riser as well.

Step 4: Prepare the New Sprinkler Head

Before installing the new sprinkler head, apply Teflon tape to the threads of the riser. Wrap the tape clockwise around the threads, overlapping each layer. This will create a watertight seal and prevent leaks.

Step 5: Install the New Sprinkler Head

Carefully thread the new sprinkler head onto the riser, turning it clockwise until it is snug. Avoid overtightening, as this can damage the threads or the sprinkler head itself. Hand-tighten, then use pliers to tighten an additional half-turn.

Step 6: Adjust the Arc and Nozzle

Once the new sprinkler head is installed, adjust the arc and nozzle to match the original settings. Use a flathead screwdriver to adjust the arc. Consult the Toro Super 700 manual for specific instructions on nozzle replacement and adjustment. Proper adjustment is critical for achieving optimal coverage and preventing water wastage.

Step 7: Test the Sprinkler Head

Turn the water supply back on slowly and observe the sprinkler head for leaks. If any leaks are detected, tighten the connection slightly. Check the spray pattern and make any necessary adjustments to the arc and nozzle. Ensure the water is reaching all intended areas without overspray onto unwanted surfaces.

Step 8: Backfill and Restore the Area

Once you are satisfied with the performance of the new sprinkler head, backfill the excavated area with soil. Gently compact the soil around the sprinkler head to provide stability. Restore the area to its original condition, taking care to avoid damaging the sprinkler head.

Troubleshooting Common Issues

Even with careful installation, some issues may arise. Addressing these problems promptly is essential for maintaining the efficiency of the irrigation system.

Leaks at the Connection Point

Leaks at the connection point are often caused by insufficient Teflon tape or overtightening. Turn off the water supply, remove the sprinkler head, and reapply Teflon tape. Ensure the connection is snug but not overtightened.

Low Water Pressure

Low water pressure can result in poor spray patterns. Check the main water supply pressure and ensure that the zone control valve is fully open. Also, inspect the nozzle for any obstructions. Debris can accumulate in the nozzle and restrict water flow.

Uneven Spray Pattern

An uneven spray pattern can be caused by a clogged nozzle or improper arc adjustment. Clean the nozzle with a small brush or needle. Adjust the arc to ensure it is properly aligned with the intended coverage area.

Sprinkler Head Not Popping Up

If the sprinkler head is not popping up, it may be obstructed by debris or damaged. Clear any debris from around the sprinkler head. If the problem persists, the sprinkler head may need to be replaced.

Preventative Maintenance

Regular preventative maintenance can extend the life of Toro Super 700 sprinkler heads and prevent costly repairs. Perform the following tasks regularly:

• Inspect sprinkler heads for leaks and damage.
• Clean nozzles to remove debris.
• Adjust arc and nozzle settings as needed.
• Monitor water pressure and flow rates.
• Winterize the irrigation system to prevent freeze damage.

By implementing a consistent maintenance schedule, you can ensure the efficient and reliable operation of your irrigation system.

Conclusion

Replacing a Toro Super 700 sprinkler head is a manageable task for most homeowners and maintenance professionals. By following these steps and troubleshooting common issues, you can restore proper irrigation coverage and prevent water wastage. Key takeaways include:

• Proper identification of the sprinkler head is crucial for selecting the correct replacement.
• Using Teflon tape on threaded connections is essential for preventing leaks.
• Careful adjustment of the arc and nozzle ensures optimal performance.
• Regular preventative maintenance can extend the life of the sprinkler heads.

By adhering to these guidelines, you can confidently maintain and repair your Toro Super 700 sprinkler system, ensuring efficient and effective landscape irrigation.
