An apparatus for facilitating servicing of a liquid-cooled electronics rack is provided. The apparatus includes a coolant tank, a coolant pump in fluid communication with the coolant tank, multiple parallel-connected coolant supply lines coupling the coolant pump to a coolant supply port of the apparatus, and a coolant return port and a coolant return line coupled between the coolant return port and the coolant tank. Each coolant supply line includes a coolant control valve for selectively controlling flow of coolant therethrough pumped by the coolant pump from the coolant tank. At least one coolant supply line includes at least one filter, and one coolant supply line is a bypass line with no filter. When operational, the apparatus facilitates filling of coolant into a cooling system of a liquid-cooled electronics rack by allowing for selective filtering of coolant inserted into the cooling system.
