What is something simple that can be done to help extend the life of firefighting nozzles?
during winter months wrap the nozzle in plastic grocery bag to protect the nozzle from road grit (grime, salt, and whatever else is kicked up by the tires). The bag will shoot off as you flow the line to check stream in the yard.
