PROBLEM TO BE SOLVED: To provide a two-way check valve which reliably leads water discharged from one pump to a pipe, while preventing any reverse flow to the other pump by interposing the two-way check valve between the pumps and the pipe, when water discharged from two pumps is led via the same pipe. SOLUTION: In this two-way check valve, a valve element (41) to close one water inlet (44) by being pushed by the water pressure when the water discharged from a pump (3) flows into the other water inlet (44) is accommodated in a valve body (40) formed so that the two water inlets (44) and (44) and one water outlet (45) are communicated with each other, and the valve element (41) is formed of a synthetic resin spherical body.
