What should the transfer valve be set to for combination sprinkler/standpipe systems?

The transfer valve for combination sprinkler/standpipe systems should be set to the pressure position. This setting allows the system to maintain the appropriate pressure for delivering water to both the sprinkler system and the standpipe system effectively.

When set to the pressure position, the valve ensures that the system can accommodate the necessary pressures required for optimal performance of both components, which is critical in an emergency situation where pressure must be maintained to adequately protect lives and property. The pressure setting is essential for the operation of fire pumps and for ensuring firefighters can utilize the standpipe system effectively.

In contrast, the other options focus on different system operations that may not be suitable for a combination system during an emergency response. For instance, the volume/capacity position emphasizes flow rates that may not prioritize pressure maintenance. Meanwhile, the standby position typically indicates a system state where no active flow is occurring, and the emergency position may pertain to specific scenarios or other configurations that do not apply to a combination system's general operation.
