Why Do Well Pumps Fail After Lightning Storms?

If your well pump stops working after a lightning storm, the storm may be the cause. A lightning strike does not have to hit your home or well directly to create damaging electrical surges. Nearby strikes can send transient energy, which cause power surges, through utility lines, grounding systems, or other conductive paths and into your home's electrical system.

Well pumps are particularly vulnerable because the pump motor is connected to the home by a long run of electrical wiring. This wiring can provide a path for surge energy to reach the pump motor, control box, pressure switch, and other components. A surge can cause immediate damage or weaken components that fail later.

A common misconception is that a single surge protector automatically provides complete protection for the whole home. While protection at the main electrical panel is an important first layer, a well pump is located on a circuit that extends away from the home. Additional surge protection at the well pump and its control equipment can provide another layer of protection.

If your well pump has failed after a lightning storm, it may be a sign that your electrical system needs better surge and power quality protection.
