How often does a fire extinguisher need to be serviced?
A. In California we are required to perform an annual maintenance. We are required to perform a 6 year tear down and service of each extinguisher. We sell and service all types of extinguishers, except plastic heads. An extinguisher installed in a stationary situation is required to be hydro-tested every 12 years. An extinguisher installed on a moving vehicle or boat, or a C02 Extinguisher, is required to be hydro-tested every 5 years.
