Where are the main sprinkler system valves usually installed?

The main sprinkler system valves are typically installed on the main riser above the water supply control valve. This location is strategic for a few key reasons.

Firstly, placing the valves on the main riser allows for easy access and visibility for inspection and maintenance, which is essential for ensuring the sprinkler system remains operational in the event of a fire. The main riser serves as the central point where the water supply enters the building, and having the valves located here simplifies the process of controlling and shutting off the system if necessary.

Additionally, the location helps to prevent potential water damage that could occur if the valves were situated in less accessible areas like the basement or attic, where they might be more prone to freezing or corrosion. Situating them above the water supply control valve also provides clear delineation for firefighters and emergency personnel, ensuring they can quickly identify where to manipulate the system during a response.

Overall, having the valves on the main riser supports both functionality and safety in fire protection systems.
