1. A fluid distribution system for a fire apparatus that is selectively operable in a testing mode and an operating mode, the fluid distribution system comprising:
a first flow meter configured to be positioned along an agent line;
a metering valve configured to be positioned downstream of the first flow meter;
a second flow meter configured to be positioned downstream of the first flow meter and an eductor; and
a controller configured to selectively operate the fluid distribution system in the testing mode, wherein, during the testing mode, the controller is configured to:
conduct a testing mode sequence including acquiring a first flow rate of a fluid flowing through the first flow meter and a second flow rate of the fluid flowing through the second flow meter and determining a performance characteristic based on the first flow rate and the second flow rate; and
modulate a current setting of the metering valve from a first setting to a second setting and conduct the testing mode sequence again at the second setting of the metering valve to verify the fluid distribution system is performing properly.
