Water pipes are not included in this package.Before purchasing,please check the water pressure at home.If the water pressure at home is greater than the booster pump, the boosting effect will not be achieved.2. When the pump leaves the factory,a small amount of water may remain in the pump.This is due to strict tests on the pump to ensure quality and meet the testing standards.This does not mean that the pump has been used.3. Please strictly follow the instructions for installation and use,and pay attention to electrical installation specifications.Before use,please carefully check the cables,power supply,etc.,and take protective measures to avoid safety hazards.We suggest that professionals install this product.4. It is forbidden to install it upside down to prevent water from leaking into the motorwhich may cause a short circuit and burn the motor.5. When installing the water flow switch,place the cover face of the water flow switch facing upwards and make sure to tighten the movable joint next to the water flow switch.Once the water flow switch is turned,the internal screws may become loose due to compression, causing water leakage.Therefore, be sure to tighten the water flow switch! But please do not tighten the live connector too much to prevent the gasket inside from being broken and the screws on the side of the water flow switch from being broken.
