I think it is necessary to fill the suction hose, too. It seems that you have done it before making this video. Waterpumps should not be started dry without filling water first. The second important rule has been not written in Chinese manuals. This is very vital in Northern cold countries. Always drain water from the pump and hoses before winter, when the temperature goes below zero degrees (Celsius). Otherwise the expanding ice will break the pump, the water space!
