ABSTRACT:
A fire hydrant cap and cover assembly which is provided with a hydrant operating wrench therefor. The cap of the assembly has an interior threaded cap portion which attaches to the threaded portion of the hydrant water outlet discharge pipe. The exterior cover is rotatably attached to the cap (and rotates with respect thereto) through an annular groove on the cap, the groove engaging a ring bead fixed on the cover. A pentagonal shaped wrench is inserted into the pentagonal shaped recessed portion in the cap by way of a circular opening in the exterior of the cover to engage the cap. Through rotation of the cap, its interior threaded portion can be unscrewed from the threaded hydrant water outlet discharge pipe to enable the removal of the cap and cover assembly. This arrangement prevents tampering with the hydrant water discharge pipe. The cap recessed portion is provided with a fluid drain and vent aperture communicating with the hydrant valve and indication of leaking on the seat.
