The present invention relates to a piping system preventing booster pump backflow. According to the present invention, booster pump damage can be prevented through automatic fluid charging into a booster pump in an environment where a fluid on a booster pump suction portion side flows backward during a non-operation of the booster pump. The present invention includes one booster pump (130) or a plurality of parallel-connected booster pumps (130); a suction pipe (120) that is connected to a suction portion (131) side of the booster pump (130) for fluid inflow; and a discharge pipe (140) that is connected to a discharge portion (132) side of the booster pump (130) for fluid outflow. Backflow prevention piping (200) is connected between the discharge pipe and the booster pump for steam supply of the fluid in the discharge pipe to the booster pump. |
