1、AUTOMATIC SENSOR SWITCH CONTROLLED BY WATER FLOW: Your faucet turns on or off and the water pump turns on or off automatically. Before turning on the water pump, please turn on the faucet to ensure that there is water flowing through the water pump 2、AI INTELLIGENT LEARNING: Intelligently learn the water flow and air in the water pipe, regardless of whether the water pressure matches the situation, which is a more effective booster solution 3、LOW PRESSURE START: The small machine cannot start automatically when the water flows through. You can press the switch button to switch to low pressure mode operation to ensure that the small flow can start 4、WATER SHORTAGE PROTECTION: When the water inlet in the pump is close to zero pressure, the pump will stop working and automatically protect 5、TECHNICAL PARAMETERS: Can be used with both tank and tankless water heaters. Maximum flow is 4.4GPM and maximum lift is 65feet. Input power is 80W, energy saving
