What substance may create corrosion in the propane piping system?

Water vapor
Leak detector solutions containing ammonia
Diesel fuel
Excessive heat

The correct answer is: Leak detector solutions containing ammonia

The presence of leak detector solutions that contain ammonia is a significant concern when it comes to corrosion in propane piping systems. Ammonia is highly corrosive to certain metals, particularly copper and brass, which are commonly used in propane systems. When leak detector solutions containing ammonia come in contact with these materials, they can lead to the deterioration of the metal over time, potentially resulting in leaks and system failures. Understanding this issue is crucial for RV technicians because maintaining the integrity of the propane system is vital for safety and performance. Other substances or conditions, while they may have their own implications (like water vapor causing rust if present long-term or excessive heat affecting the overall pipe integrity), do not specifically contribute to corrosion in the same manner as ammonia-based solutions do. Thus, recognizing the impact of ammonia on metals in the propane piping system is key to preventing corrosion and ensuring a reliable and safe operation.
