AWWA C503 Wet Barrel Hydrant
A Wet-Barrel Hydrant is used in water-supply service in areas where the climate is mild and freezing temperatures do not occur and it has one or more valve openings above the ground line and, under normal operating conditions, the entire interior of the hydrant is subjected to water pressure at all times. Each outlet nozzle has an independent, compression-type valve (i.e., working with or against the pressure) that controls discharge from that particular outlet.
