What is the required pitch for piping in cold storage areas for cross and feed main?

The required pitch for piping in cold storage areas for cross and feed mains is indeed 1/2" per 10'. This specification is crucial because it helps prevent the accumulation of condensation, ice, or water in the piping system, which can occur in cold storage environments. Proper pitch ensures that any moisture that may form due to temperature differences can drain away effectively, reducing the risk of blockages or damage to the system.

In many sprinkler systems, especially in cold storage or freezer environments, managing condensation is vital. The specified pitch allows for optimal drainage, which is essential for maintaining proper flow and function within the sprinkler system. The choice of 1/2" per 10' is a standard practice that aligns with industry guidelines, ensuring that the system remains effective and reliable under varying temperature conditions.
