A diverter spout has a drain pipe, a connecting sleeve, an offset shaft, a resilient element between the drain pipe and the offset shaft, a pole for manual operation, a supporting sleeve and an envelope. At least a leakproof rubber ring is mounted around the offset shaft. Due to interferential friction between the leakproof rings and the connecting sleeve or the supporting sleeve and water pressure, a blocking portion of the offset shaft controls the water to flow only through a spout. In normal state, the resilient element overcomes interferential friction between the leakproof rings and the connecting sleeve or the supporting sleeve and controls the water to flow only through a drain opening of the drainpipe. Therefore, water diverts reliably without leakage.
