If I have a building with sprinkler system for the storages areas and a standpipe with hoses sistem for the rest.
and the building have a external conexion for firefighters, do i need to consider the extra demand of internal/external hoses for the capacity of the tank?
I am a little confused about that.. when use internal or external hoses..
*Some hoses are in storage areas but are part of the standpipe sistem..
*the system does not connect to the public water network
* both systems are connected to the same tank.
