The hydrant assembly having a check valve is comprised as follows. A female screw hole (21) is formed in the curved part of an elbow pipe (20). A check valve (80) is detachably coupled to the female screw hole (21). The top end of a protection pipe (200) is coupled to the top end of the elbow pipe (20), and the bottom end is located under the check valve (80) to protect the check valve (80) from buried soil. An air valve (90) is opened and closed to exhaust or inhale air between a fixing pipe (30) and a lifting pipe (40). |
