For gas lines installed in potentially wet areas, what slope is recommended to prevent issues with condensation?

The recommended slope for gas lines installed in potentially wet areas is 1/4 inch per 15 feet. This slope is crucial because it facilitates proper drainage of any condensation that may accumulate within the gas line. In wet environments, condensation can form inside the line due to temperature changes or varying pressure conditions. A slope of 1/4 inch in 15 feet creates a gradual decline which ensures that any moisture that develops can flow away from the gas appliances and prevent issues such as corrosion or the introduction of water into the gas system.

In this case, the specified slope effectively balances efficient drainage while maintaining the structural integrity of the gas line. The choice of 1/4 inch in 15 feet is also within industry standards, which stresses the importance of proper installation practices to enhance safety and reliability in gas systems.
