What is the purpose of a drip leg in a propane installation?

The purpose of a drip leg in a propane installation is to collect any condensate that may accumulate within the piping system. Propane is typically stored and transported in a liquid state, and when it vaporizes into gas, there can be residual moisture and other contaminating substances that can condense within the gas lines. The drip leg acts as a trap to capture this condensate, preventing it from causing blockages or corrosion in the system. This is crucial for maintaining the integrity and efficiency of the propane system, as the presence of liquid in the gas lines can lead to malfunctioning appliances, unreliable operation, or even hazardous conditions. Proper installation and maintenance of the drip leg ensure that the propane remains in a safe and usable state, contributing to the overall safety of the propane system.
