Don’t Let Lightning Strike Twice: Why Your Irrigation System Needs Professional Surge Protection Now

Modern irrigation systems represent significant investments for property owners, with automated sprinkler controllers, pumps, and sophisticated electronic components working together to maintain healthy landscapes. However, these sensitive electronic systems face a constant threat from power surges and lightning strikes that can cause thousands of dollars in damage in mere seconds.

The Hidden Costs of Unprotected Irrigation Systems

The Insurance Institute for Business & Home Safety study found that $26 billion dollars was lost due to non-lightning power surges. In addition, there are about 25 million lightning strikes in the US each year that cause between $650M to $1B in losses according to the Insurance Information Institute, State Farm©. What makes these statistics particularly alarming for irrigation system owners is that lightning strike damage to sprinkler systems often goes undetected for months, and more often than not, the homeowner or property owner was not aware that their sprinkler system had been hit by lightning.

Damage from a voltage surge may be isolated to your irrigation controller, whereas lightning strikes could blow your controller off the wall, melt together multi-strand wiring and destroy a solenoid or the entire valve. The financial impact extends far beyond the initial equipment replacement, as this excess of pressure can cause cracked pipes, damaged pump casings, valve damage, and leaks.

How Lightning and Power Surges Devastate Irrigation Equipment

Your sprinkler system has wiring that travels underground to each valve in your yard from your irrigation controller and the copper in the wire can be a conduit for the powerful lightning that hits the ground anywhere near your home including the next door neighbor’s tree. The lightning then travels down the copper wire to your valves and controller doing possible damage all along the way.

The damage isn’t always immediately obvious. As a result of lightning strike damage or a power surge the controller could send out power to multiple zones at the same time, even when the controller is in the “Off” position. Additionally, when there is any loss of power – temporary or prolonged – the flow of water through your irrigation system is interrupted. This results in a surge of alternating low and high pressure, which exerts five to six times more pressure on your system than usual.

Professional Surge Protection Solutions

Today’s increased reliance on very sensitive electronics makes surge protection an important topic for Commercial Irrigation System applications utilizing Sprinkler Systems. Modern surge protection goes far beyond simple power strips. NEC/NFPA 70 require that Surge Protective Devices (SPDs) shall be UL1449 Listed.

Surge Protectors – Also called “surge suppressors” or “lightning arrestors,” these devices are integrated into the wiring of your system and channel the surges away from your equipment. However, effective protection requires a comprehensive approach that includes proper grounding systems and strategic placement of protection devices.

For pump systems specifically, surge protectors take the extra energy from a lightning strike or electrical spike and divert it safely into the ground. By stabilizing the voltage, they prevent your pump motor and control systems from burning out. A surge protector is a fraction of the cost of replacing a well pump system.

Why Professional Installation Matters

While surge protection devices are essential, their effectiveness depends heavily on proper installation. It is important that both the controller and the decoders are grounded to ground rods or plates with less than 10 Ohms resistance. Professional electricians understand that for the most effective protection, you should have a TVSS at the meter, one at the main panel, another at each subpanel (if any), and one at each sensitive electronic device.

The complexity of modern irrigation systems requires expertise that goes beyond basic electrical work. One of the major issues with Irrigation we have is Surges caused by nearby Lightning Strikes. Although we cannot stop the strikes, we can offer some surge protection, such as External Surge Protectors.

Our core business is centered on providing wiring services, electrical repairs, upgrades, installations, and additions to North Chatham, Orange, Durham, and Alamance counties in NC.

The Cost of Waiting

The decision to install surge protection shouldn’t wait until after the first lightning strike. The VFD was around $2800 a couple of years ago, so I shutter to think what it’ll be now… This real-world example from a property owner who experienced repeated lightning damage to their irrigation pump demonstrates the escalating costs of replacement equipment.

Pool equipment is not only costly to repair, but also highly susceptible to lightning-induced surges. Without adequate surge protection, there’s a significant likelihood of failure over time. The same principle applies to irrigation systems, where the combination of outdoor installation and sensitive electronics creates the perfect storm for surge damage.

Taking Action

Protecting your irrigation system from lightning and power surges isn’t just about preventing inconvenience – it’s about safeguarding a significant investment in your property’s infrastructure. With professional surge protection properly installed and maintained, you can have confidence that your automated sprinkler system will continue operating reliably, regardless of what Mother Nature brings.

Don’t wait for lightning to strike. Contact qualified electrical professionals today to assess your irrigation system’s surge protection needs and implement a comprehensive solution that will keep your investment safe for years to come.
