1. This is a clean water pump. It cannot pump water with particulate matter. It is recommended to install a check valve and a filter. 2. This pump can be used in this way, but it is necessary to ensure that all outlet pipes are opened to allow the water pump to operate normally. 3. The water pump can work continuously 2 hours. After the water pump continues to work, the surface temperature will be very high, so be careful not to get burned.
