Abstract: A method for delivering water through a fire hydrant is described. The method includes unlocking a sprinkler cap control lock on the fire hydrant, removing the sprinkler cap control lock to access the operating nut of the fire hydrant and activating the operating nut to deliver water through the sprinkler ports in at least one cap on the fire hydrant. A fire hydrant with a sprinkler cap having a plurality of sprinkler ports and a sprinkler cap control lock, wherein the sprinkler cap control lock covers and prevents access to the operating nut is also described. Systems and methods for lubricating the operating nut and for improved sealing surfaces in the fire hydrant valves are also described.

Abstract: A method of draining a standpipe includes moving a valve control device toward a closed position sufficient to uncover at least one drain hole before the valve control device achieves a fully closed position, the at least one drain hole being disposed in a slot of a saturation ring and draining a contents of the standpipe through a drain route to an external portion of the standpipe, the drain route is defined by the drain hole in the valve seat ring, drain ports in the drain ring, outlet notches and a drain channel in the saturation ring. The drain hole is radially offset from each of the drain ports in the drain ring and each of the drain ports are radially offset from each of the outlet notches in the saturation ring. A valve control device is also disclosed.

Abstract: A locking fire hydrant includes a fire hydrant body having an internal channel extending between a main cap recess and an auxiliary cap recess defined therein. A plunger assembly including first and second plungers is disposed within the internal channel. The first plunger is disposed such that an end thereof is capable of extending into a main cap recess and the second plunger is disposed such that an end thereof is capable of extending into an auxiliary cap recess. When the second plunger is actuated by mounting a locking cap on the fire hydrant body, one of the ratchet teeth provided on the back side of the auxiliary cap engages the second plunger to prevent the auxiliary cap from being removed from the fire hydrant body. A locking cap, an opening tool, and methods of securing an auxiliary cap to a fire hydrant also are described.

Abstract: A valve control device includes an operating stem, a valve top plate, a valve seat rubber, a valve bottom plate, and a valve seat ring. The valve top plate has a conical base with at least three stabilizer arms extending therefrom. Each of the at least three stabilizer arms has a flat outer surface. The valve bottom plate secures the valve seat rubber between the valve bottom plate and a flat bottom surface of the valve top plate. The valve bottom plate, the valve seat rubber, and the conical base are mounted on the operating stem. The valve seat ring has multiple slots, with each of the slots corresponding to one of the at least three stabilizer arms. A standpipe drain system, a method of draining a standpipe, and a locking fire hydrant with a valve access channel drain also are described.
