Important Notice: The max suction height is 7/23ft and it takes some time before automatic pumping. Adding some pilotage water to the head of the pump will help accelerate the flow rate of inlet. The closer water inlet pipe and the pump is, the better the effect. Impurities are not allowed in the water and there is a jam if the diameter is more than 1mm. There is a dewatering outlet designed for draining the left water in the machine if it will not be in use for a long term. Water Inlet and outlet need to be sealed up when you connect pipes. 1.6HP Homdox Garden Pump The compact and durable design allows you to carry around conveniently and ensures long time use.
