PURPOSE: A piped-water mold which prevents pinhole phenomenon and includes an air discharge member and a rod space part and a manufacturing method thereof are provided to improve strength and quality of the piped-water mold by preventing the pinhole phenomenon. CONSTITUTION: A rod space part is formed in order to be independently divided from a cold and hot water inlet. The rod space part has an air discharge member(60) in order to discharge air or gas from the mold. The air discharge member has a plurality of stripe protrusions(61). A protrusion unit(62) is formed on the center of the stripe protrusion. An air vent(V) is formed in the protrusion. A guide groove(53), in which a rod is inserted, is formed on the lower part of the rod space part. A guide groove has an air vent in order to prevent the pinhole phenomenon.
