Under what conditions are drips required on LP gas systems?

Always required regardless of moisture levels
Only if the Authority Having Jurisdiction (AHJ) requires it or in cases of high moisture levels
Only when the installation is indoors
Only if there are previously reported issues

The correct answer is: Only if the Authority Having Jurisdiction (AHJ) requires it or in cases of high moisture levels

Drips are essential in LP gas systems primarily to manage any condensation that can occur within the gas lines. When the gas cools as it travels through the piping, moisture in the gas can condense and potentially lead to water buildup, which can cause performance issues or safety hazards. The correct approach is to install drips mainly if there are high moisture levels in the environment, as these conditions increase the likelihood of condensation. Furthermore, the decision also often depends on the requirements set forth by the Authority Having Jurisdiction (AHJ), which may have specific codes or standards regarding moisture control in gas systems. If there are previously reported issues related to moisture or condensation in the system, that could also warrant the installation of drips. However, adhering strictly to the authority's regulations and environmental conditions provides a balanced and safe approach to managing moisture in LP gas systems.
