The utility model discloses a water pump reliability detecting test stand, which comprises a support (1), a scroll casing (6), a water inlet (3), a water outlet (2) and a fixed to-be-detected water pump (4). The scroll casing (6) is connected to the support (1), the water inlet (3) and the water outlet (2) are arranged on the scroll casing (6), and the top end of the scroll casing (6) is further equipped with an exhaust opening (5). Because the top end of the scroll casing of the water pump reliability detecting test stand is further equipped with the exhaust opening, the exhaust opening can be opened after the test stand normally works for a period of time to discharge air collected in the scroll casing of the test stand, thereby enabling air in the scroll casing of the test stand to always be kept in a range of not affecting normal operation of the to-be-detected water pump, avoiding the problem of cavitation erosion of the water pump caused by large quantities of accumulated air, and guaranteeing accuracy
