Adjustable Flow Rate: With a flow control valve, the mini fountain pump can be adjusted up to 50 GPH (200L/H) to fit your need; Recommended H-Max (Lift height): 0.8 ft. Note: 50 GPH is the theoretical flow rate at zero lift; the actual output decreases with pipe resistance, lifting height. And the higher the lifting height is, the lower the flow rate will be. For example, the flow rate is 50 GPH at 0 ft (without any water pipe), 25 GPH at 1 ft, 35 GPH at 0.8 ft, and nearly 0 GPH at 1.5 ft
