PIPE JOINT MEMBER AND HEAT SOURCE MACHINE

PROBLEM TO BE SOLVED: To provide a pipe joint member that can be used for both of a case to individually discharge drain water and the other waste water and a case to discharge them together by confluence and does not require a complicated operation for switching between an individual drainage state and a confluence drainage state, and to provide a heat source machine including such a pipe joint member.SOLUTION: Two or more incurrent ports (79, 84), two or more drain ports, and two or more communicating ducts connecting the incurrent ports (79, 84) and the drain ports are respectively provided, and a bypass path connecting at least a pair of communicating ducts and a ventilation path linking the inside and outside are formed. Then, at least one of the communicating ducts is connected to a drainage system, and while two or more incurrent ports are located on an upper side, two or more drain ports are located on a lower side. Further, a pipe joint member is formed which is attached to a housing of a heat source machine while the two or more drain ports are exposed to the outside of the housing.
