The Mueller Improved fire hydrant system incorporates extension kits to adjust hydrant height based on installation requirements. Documentation details procedures for adding extensions, replacing components like traffic flanges and stem couplings, and provides component lists for extension kits. This article details the installation of extensions, component lists, and related maintenance procedures based on available documentation.
Adding an Extension to Mueller Improved Fire Hydrants
Mueller Improved fire hydrants can be modified with extensions to achieve the necessary operating height. The provided documentation references instructions for “Adding an Extension” and “Inserting Extension Section,” appearing multiple times within the Mueller Improved Instruction Manual. Specific details regarding the process itself are not fully elaborated upon in the available documentation; however, the repeated references indicate this is a supported and documented procedure. The documentation does not specify tools required for installation.

Replacing Traffic Flange and Stem Couplings
The Mueller Improved Operating Instructions Manual details procedures for replacing traffic flanges and stem couplings. Two distinct procedures are outlined, differentiated by the stem coupling material: brass and steel.
Replacing Traffic Flange and Brass Stem Coupling (Sealed Oil Reservoir 1962 Style)
