What pitch should gas piping be installed with for proper drainage?

The correct pitch for gas piping is essential to ensure proper drainage and to prevent the accumulation of moisture and condensate within the pipes. A pitch of 1/4 inch per 15 feet of run is adequate for allowing any liquid that may occur from condensation to flow towards the designated drainage points. This ensures that the gas line remains functional and minimizes the risks associated with gas leaks or blockages that could occur if water were to accumulate in the line.

Proper drainage is particularly important in gas systems because trapped moisture can lead to corrosion, deterioration of the piping material, and potential failure of the gas delivery system. Ensuring that the pitch is consistent throughout the installation helps maintain the integrity and reliability of the HVAC system over time, aligning with industry standards for safety and performance.
