As winter fades and the first signs of spring begin to appear, many homeowners start thinking about getting their lawns and landscapes ready for the growing season. One of the most common questions we hear is: When should you turn your sprinkler system back on in New Jersey?
The answer depends largely on weather conditions, soil temperatures, and the risk of overnight freezing.
Timing Matters in New Jersey
In most parts of New Jersey, sprinkler systems are typically turned back between late March and mid-April. By this time, temperatures are consistently warmer, and the risk of freezing overnight has significantly decreased.
Turning your system on too early can be risky. If temperatures drop below freezing, any water remaining in the pipes can freeze and expand, potentially causing cracks in pipes, valves, or sprinkler heads. This can lead to expensive repairs before the irrigation season even begins. Waiting until the threat of freezing has passed helps protect your irrigation system and ensures it’s ready to run efficiently for the spring and summer months ahead.
Why a Professional Spring Startup Is Important
A common misconception is that turning your sprinkler system on simply means opening the water valve. However, after months of snow, ice, and fluctuating temperatures, your system needs a proper inspection and startup process to ensure everything is functioning correctly.
A professional irrigation startup typically includes:
• Slowly pressurizing the system to avoid damage
• Inspecting sprinkler heads for cracks or clogs
• Checking valves and valve boxes for winter damage
• Adjusting sprinkler heads for proper coverage
• Testing the controller and irrigation zones
• Ensuring rain sensors and smart controllers are functioning properly
These steps help identify small problems before they become larger, more costly issues.
Benefits of an Early Spring Irrigation Inspection
Scheduling your sprinkler startup early in the season has several advantages. It allows you to catch issues like broken sprinkler heads, leaking valves, or clogged nozzles before your lawn relies heavily on irrigation.
An inspection also ensures your system is running efficiently, preventing water waste and helping keep your utility bills under control.
Most importantly, it ensures your lawn and landscape receive even, consistent watering as temperatures begin to rise, and plants start actively growing.
Signs Your System May Need Attention
If you notice any of the following after turning on your system, it may be time for a professional inspection:
• Sprinkler heads not popping up
• Uneven watering or dry patches
• Water pooling near valves
• Unusually high water bills
• Low water pressure in certain zones
Addressing these issues early helps keep your irrigation system operating smoothly all season long.
