ABSTRACT:
The present invention is directed to a utility hot and cold water mixing system consisting of three components, a hot water Y-coupler with a flow control ball valve on one side, a central Y-coupler with a flow control ball valve and a cold water Y-coupler on the other side. A unique configuration derived by twisting the connecting hoses maintains the central Y-coupler in an upright position. The system has been designed to mount to the hot and cold water faucets used by the washing machine no matter what the spacing is. It allows the temperature of the water to be preset so that each time the control valve is opened the proper temperature water is provided and no adjustments are required while providing full pressure hot and cold water to a washing machine.
