Newer designs simply enclose the top of the barrel without making a design statement. Another distinguishing characteristic of wet barrel hydrants is the valve stem guides of the individual valves as to how they were designed to be removed. Pumper and hose nozzles can be distinguished from each other by the relative sizes on the symbols. Hydrants can be found where the centerline of the pumper nozzle is perhaps an inch lower than the hose nozzles. This guide considers these nozzles to be of the same height.
Red nozzles are lower than black.
And blue nozzles, commonly used for wet barrel hydrants are lower yet. Those who print this guide will therefore need a color printer to avoid confusion. These 'hand-wheel' valves are mounted inline with the nozzles. The distinction is established by the location of the manufacturer's name cast onto the barrel. The nozzles are always 90 apart with the other two symbols.
