A spray hose assembly for a washing machine appliance is provided. The spray hose assembly includes a hose assembly fluidly connecting a spray nozzle and an outlet of a fluid source valve. The fluid source valve additionally includes a first attachment end and a second attachment end. The first and second attachment ends of the fluid source valve are configured to be fluidly connected between a water source and a supply line of the washing machine appliance such that the water source valve may provide a flow of water to the spray hose assembly without preventing the washing machine appliance from maintaining fluid connection with the water source.
