IMPORTANT: When Hale FoamMaster system is ordered
without a tank option the installer must provide the
fittings necessary for flushing the foam system to be
NFPA compliant. These components are:
Foam concentrate check valve; prevents water
contamination of foam tank and pressurization of in-
line strainer/valve assembly.
Tee; to connect flush water hose to foam concentrate
hose.
Flush Water Check Valve; prevents foam
contamination of water system.
