What is the primary reason for having adequate drainage in a sprinkler system?

The primary reason for having adequate drainage in a sprinkler system is to prevent water buildup and pressure issues. Proper drainage ensures that water does not accumulate within the system, which can lead to several complications such as increased pressure that could stress the system's components or even cause failures due to excessive pressure. Additionally, stagnant water can contribute to corrosion or biological growth, compromising the effectiveness of the sprinkler system over time. Ensuring there is a reliable drainage mechanism allows the system to function correctly and maintain operational integrity, particularly in the case of a fire event where timely water discharge is crucial.
