The claimed universal polymeric molded fire hydrant is lightweight, weather resistant and will meet the UL, FM, NFPA and AWWA standards established for conventional metallic hydrants. Polymeric fire hydrants will also exceed standard performance expectations by eliminating rusting, binding, cracking and the associated need for periodic painting and lubrication. This polymeric fire hydrant costs less to produce than traditional metallic models providing significant costs savings to commercial and residential developers as well as municipalities. The inherent light weight nature of the units will reduce manpower and heavy equipment required to install it. This hydrant can be manufactured to resemble all existing traditional hydrant designs and performance specifications and will allow for future design modifications as future performance specifications and designs evolve.
