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.

## Background
FIELD OF THE INVENTION
This invention relates to the field of devices used to connect to garage or laundry room hot and cold water faucets to facilitate the use of full pressure temperature controlled water for utility purposes such as washing pets and for removing ice, snow, oil and salt from vehicles, sidewalks and driveways. More specifically this patent deals with a unique system that allows the water temperature to be preset so that each time the control valve is opened the proper water temperature is provided and no adjustments are required while additionally providing full pressure hot and cold water to a washing machine.
BACKGROUND OF THE INVENTION
Washing of pets should be done with tepid water not cold, because pets should not be subjected to the cold water shock when they are bathed, warm water cuts their body oils more effectively and the pets will stay calmer during the washing process with warm water and will be inclined to welcome another bath. Often garden hoses are connected to cold water landscape spigots for washing pets.
Presently, there is no simple and economical means to get a controlled tepid water source in the area of the garage, which does not require adjustment, for washing vehicles. In cold climates where ice, snow and road salt are problems; a covenant tepid water source would be a great asset to homeowners.
Most garages and laundry rooms furnish hot and cold water supply for washing machines, some with separate faucets for direct connection to washing machines, and others with a mixer faucet over a laundry tub with “T” connections to the washer. Additionally some mixer faucets have a threaded end that will connect to a garden hose, but when these are used, the water temperature must be adjusted each time it is turned on. On some newer homes, a valve box is incorporated into the laundry facility. This 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, along with adapters for newer homes with valve boxes, accomplishes the task simply and effectively while supplying full pressure hot and cold water to the washing machine.
A wide variety of mixing faucets and valves are on the market for the purpose of controlled mixing hot and cold water. Most common are the mixing faucets used on sinks within the house. These mixing faucets require adjustment every time the water is turned on to get an even flow of tepid water. Many sophisticated water flow mixing valves are available on the market, some with electronic controls to supply an even flow of tepid water every time the water is turned on. These expensive mixing valves are generally used for commercial purposes and are not readily available at pet supply stores, hardware stores or automotive supply stores. Additionally there are many devices for washing pets available, some large for a commercial use and others for home use, but they use conventional mixing faucets where the water temperature on them must be adjusted each time the devices are used to wash pets.
In this respect, before explaining at least one embodiment of the invention in detail it is to be understood that the invention is not limited in its application to the details of construction and to the arrangement of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. It is also to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.
SUMMARY OF THE INVENTION
The preferred embodiment of this invention will have a unique system of components consisting of a hot water Y-coupler, a central Y-coupler and a cold water Y-coupler connected by two hoses. The hot water Y-coupler will incorporate a flow control ball valve to adjust the desired temperature of the water put out by the pet wash system. On one side of the hot water Y-coupler is a male threaded end to connect to the hot water hose of a washing machine providing full hot water pressure. On the other side of the hot water Y-coupler is a crimped hose fitting connected to the hot water connecting hose attached to the central Y-coupler. The hot water Y-coupler is connected to the hot water faucet with a hose bib connecting nut. The central Y-coupler will attach to the hot water connecting hose and the cold water connecting hose with similar crimped hose fittings. A flow control ball valve on the hot water Y-coupler will adjust the volume of hot water through the system while the flow control ball valve on the central Y-coupler will adjust the volume of tepid water put out by the system. The cold water Y-coupler will be connected to the cold water faucet by the means of a hose bib coupling nut and will supply full pressure cold water to both the washing machine cold water hose and the central Y-coupler. The flow control ball valve on the central Y-coupler may be turned on and off as many times as desired and the same temperature of water will be available through the system. A unique feature of the system is the twist of the flexible hot and cold water connecting hoses. There is enough tensile memory in the hoses that by twisting them in the configuration that they are shown in the illustrations they will spring back to the upright position. Without this concept, the central Y-coupler would fall down behind the washing machine being difficult to retrieve. It must be understood that when the system is first turned on some cold water in the hot water lines must be flushed out before the desired temperature is delivered. The spacing of the hot and cold water faucets is not critical due to the flexibility of the hot and cold water connecting hoses on the device. Adapters are required to connect the pet wash hot and cold water mixing system to the hot and cold water valves in the valve boxes used on newer homes. This system may also be installed to the hot and cold water sources on conventional mixer faucet over a wash tub to alleviate the unnecessary adjustments required every time the water is turned on and off to achieve a desired temperature of water for washing pets.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
