Electric water heaters, ubiquitous in households, occasionally suffer from leakage accidents, resulting in tragic consequences. The primary culprits behind these leaks are corrosion and aging of the heating elements, deterioration of internal wiring insulation, grounding system failures, and malfunctioning leakage protection devices. To mitigate these risks, regular maintenance and inspections are paramount. Implementing reliable grounding systems, installing leakage protectors, and maintaining a dry environment around the heater are essential preventive measures. The anti-electric wall feature in electric water heaters serves to reduce leakage current by increasing the resistance in the water path, thus lessening the potential harm to humans. Nevertheless, this feature alone cannot prevent leaks, emphasizing the need for routine checks on the heater's condition. Prioritize safe electricity usage and take proactive steps to avert accidents.
