Sprinkler Heads:
Inspecting and adjusting sprinkler heads is one of the easiest yet most impactful tasks in your spring irrigation system startup. As you run each zone, carefully observe the spray pattern of each head. Look for signs of clogs, misalignments, or damage. Clogs can be cleared by removing and rinsing the head, while misaligned heads can often be adjusted by hand or with a simple tool. If you notice any cracked or broken heads, replace them promptly. Ensuring proper coverage and alignment of your sprinkler heads will maximize watering efficiency and prevent dry spots or overwatering in your landscape.
In summary:
- Run a test spray in each zone and conduct a visual inspection
- Check for clogs, misalignments, and damage.
- Clean or replace sprinkler heads as needed.
- Adjust spray patterns for optimal coverage.
Backflow Preventer:
The Importance of Backflow Preventers
Protecting your water supply is paramount, and that's where backflow prevention devices like the Pressure Vacuum Breaker (PVB) play a crucial role. These devices prevent contaminated water from flowing back into your home's potable water system, safeguarding it from potential hazards.
After a harsh winter, inspecting your backflow prevention device is essential. Start by locating your PVB, typically found outdoors near an exterior wall or in a recessed ground box, or indoors near the irrigation system's water shutoff. Before turning on your irrigation controller, close the PVB's valve completely. Next, open the isolation valve located between the water meter and the PVB. Then, carefully reopen the PVB's valve, checking for any leaks around the connections. If the arrow on the PVB indicates the wrong flow direction or you notice any leaks, it's crucial to call a professional for repairs. Remember, a properly functioning backflow preventer is your first line of defense in maintaining a clean and safe water supply.
In summary:
- Verify proper functionality.
- Inspect for leaks or damage.
