PROBLEM TO BE SOLVED: To provide a draining pipe unit for further improving safety by further remarkably reducing suction pressure in suction in addition to a characteristic of relatively easy in installation work with a simple constitution without risk of failure in maintenance-free by wholly eliminating a mechanical movable part and an electric contact point. SOLUTION: This opposed liquid draining pipe unit 1 is composed of a cross-sectional circular vortex chamber 2, a first inflow pipe 3a of communicating and connecting the one end side 32a with and to the vortex chamber 2, a second inflow pipe 3b of communicating and connecting one end side 32b with and to the vortex chamber 2 and a liquid delivery pipe 41 installed in the axial direction on one side surface 23 of the vortex chamber 2, and is formed by respectively communicating and connecting the one end sides 32a and 32b with and to the vortex chamber 2 by linearly opposing the first inflow pipe 3a and the second inflow pipe 3b from the right and left in the tangent direction of an inner peripheral part predetermined position of the vortex chamber 2.
