     BACKGROUND OF THE INVENTION  
      1. Field of Invention  
      This invention relates to a toilet system attached a multi-purpose hand held water spraying apparatus, engaging in delivering instant water supply for personal and environmental hygiene.  
      2. Description of Related Art  
      The prior application has been added and changed with new features to be adapted to the different environments and usages. The multi-purpose hand held water sprayer in the present invention, namely a “sprayer’, has three components: a controller, an extension bar, and a spray tip to deliver different types of water spray. The female and male couplers of the components are linked using quick connection, wherein the male couplers carrying a multiple O-rings are secured to the female couplers. However, the quick connection may easily be disconnected by the high water pressure or any other strong pulling forces. The lock elements are provided on the couplers to prevent easy disengagement while in use. Also, the various types of caps are presented for the spray tip to supply multiple patterns of the water spray for the use of the general and medical purposes. Besides, the injection apparatus is provided to supply the water sprayer with external soap or medicine fluid. The medical purposes would be for the use of douche or enema system with or without the injection apparatus.  
      The earlier application has presented the triple or more layered fortified flexible hose which is composed of a smaller inner tube enclosed by the middle layers of the preferably braided metal mesh elements for reinforcement and an outer layer of the exterior decorative tube. The current invention includes the fortified flexible hose having the rollup attachment of the triple or more layered hose to the coupling sleeve for additional reinforcement of the connection. The rollup attachment affords more length for movement of the middle layers and thicker diameter for clamping with the flanges, enabling to hold continuous high water pressures for water supply in remote area.  
      The water hammer is the sound of moving water having the sudden change in water velocity by the closing of the valve. It occurs when a transfer system is quickly started or stopped. The inertial force of the water is transferred from the water to the pipe and then into the plumbing fixtures of the home. It causes problems such as loud noise throughout the plumbing and destructiveness of joints and fittings, which can be controlled by the installation of water hammer arrestor or air chamber, or both. The water hammer arrestor is a sealed unit that contains a spring and a waterproof air bladder to absorb the inertial force of the moving water. The air chambers are vertical sections of pipes with caps on the ends that are attached with T-adapters to the existing lines near the shut-off valves. The water hammer arrestor or the air chamber is provided in the invention to reduce the problems, if the water hammer occurs.  
      The earlier application has introduced the mixing valve to supply tempered water at the outlet was not implied the check valves at both inlets to stop the reverse flow of water. Many mixing valves contain the built-in check valves, but there are some mixing valves that do not have them. The external check valves are introduced in the current application at the inlets of those mixing valves that do not have them. The various types of sources including the water heater and connections are presented in order to supply the tempered water. In addition to the T-adapter assembly in earlier application, there are different types of valves are introduced for water supply by adding another valve onto the existing valve or replacing the old one with a valve having dual outlets. The dual outlets of the valve would be controlled by a single knob or dual individual knobs. The tempered water may be obtained from a faucet of the sink near the toilet system or from the valve for the hot water source under the sink by using a mixing valve having built-in check valves. Therefore, the current invention illustrates some examples of the various types of components and connections to supply tempered water for the sprayer.  
     SUMMARY OF THE INVENTION  
      The present invention includes the lock elements of the components having a key element on the male coupler of the components and a recess element on the female coupler as the counterpart. The key element on the male coupler is inserted to the recess element on the female coupler and rotated to be locked each other, reinforcing the connection of two components. The various sizes and shapes of the caps for the spray tip are provided to offer many patterns of water spray for various applications. The straight water spray can be applied on a limited area and the radial spray is for wide region coverage. The elongated caps having various shapes of bodies and holes can be applied for the douche or enema system with a removable protective shield at the base. The injection apparatus connected to the sprayer is for addition of the external soap or medicine fluid to water spray, offering more personal or environmental hygienic features. The apparatus has a main body for connecting the water channel and an auxiliary body with a control valve for injecting the external fluid. The main body and the auxiliary body contain the check valves to stop the reverse flow and the couplers with seals for connection. The sprayer is connected to the three or more layered fortified flexible hose that has the rollup attachment of the reinforcement middle layers against the coupling sleeve. The middle layers are preferably braided metal mesh and their end parts are rolled over the edge of the outer ornamental layer to strengthen the attachment. The filter as an elective element is added to the other end of the flexible hose to eliminate impurity in the water. The valve is connected to the filter for regulating and turning off the water flow. The valve is then connected to a water hammer arrester or an air chamber to avoid situations that create water hammer due to the quick closing valve of the controller.  
      The water heater is employed to supply hot water with a control valve connected to its inlet line. The water heater having a storage tank that contains the hot water may use a mixing valve preferably the anti-scald mixing valve to supply the tempered water. There is a tankless water heater that heats water to the preset temperature for use, which may not require the mixing valve. The mixing valve has a control knob to adjust the outlet temperature by mixing the hot and cold water. The water temperature at the outlet of the mixing valve can be measured by the thermometer located at the T-adapter. The inlet of the T-adapter is connected to the outlet of the mixing valve. One outlet of the T-adapter is for connecting to the water hammer arrestor or the air chamber and the other outlet is for the return line. The return line is for guarding against the hot water spike delivered from the water heater and requires a check valve to stop the reverse flow. The water pressure regulator with water pressure gauge assures the proper water pressures for water supply to the system.  
      The multiple types of valves are presented for water supply in addition to the T-adapter with coupling adapters. One type is adding an external valve to the existing valve to obtain the outlet for the water supply. Other type is replacing the existing valve having single outlet with the one having dual outlets. The valve having dual outlets can be controlled by a single knob simultaneously or by dual knobs individually to control the flow of water. The outlet obtained from one of the various types of valves can be connected to the inlet of the water heater with or without an additional valve. The outlet of the water heater is then connected to the fortified flexible hose for use of the tempered water. This type of connection simplifies the installation of the water heater, but may require a certain type of safety device at the outlet such as a thermostatic switch. The tempered water can be obtained from a faucet on the sink having the hot and cold water provided near the toilet, which may be for temporary use and require the adapter for coupling of the fortified flexible hose to the outlet of the faucet. It can also be obtained from the hot water source under the sink by adapting one of the multiple types of valves presented in the above, which may require the mixing valve with the built-in check valves at the inlets and a valve to control the flow.

However, there are many mixing valves that include the built-in check valves at the inlets, which may not require any external check valves. The mixing valve  91  has a control handle  917  to adjust the temperature of the water at the outlet. There are different types of mixing valves available. The mechanical mixing valve adjusts water flow using a mechanical valve movement to blend hot and cold water. The automatic pressure balancing mixing valve regulates the water flow of the hot and cold water supply lines by sensing changes in water pressure in one line and adjusting water flow in the other supply line accordingly. The thermostatic mixing valve senses the outlet temperature and compensates for fluctuations in incoming hot and cold water temperature to blend hot and cold water producing tempered water. The combined thermostatic and pressure balancing mixing valve senses the outlet temperature and incoming hot and cold water pressure and compensates for fluctuations in incoming hot and cold water temperature and pressures to stabilize the outlet temperature. All of the mixing valves preferably have a thermostatic limit stop feature incorporated so that the valve automatically shuts off the hot water if the cold water supply fails.
