     BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present invention relates to the field of water supplies and sewage, more specifically, fresh water plumbing connection. 
     A shower is a bathing apparatus that is installed within a residential plumbing system. For the purposes of this disclosure, a shower further comprises a hot water line, a shower valve, a shower head feed line and a shower head. The hot water line feeds water from a water heater to the shower valve. The shower valve controls water flow into the shower head feed line. The shower head feed line routes water from the shower valve to the shower head. The shower head discharges water from the residential plumbing system for use in bathing. 
     Within residential plumbing systems a lack of continuous water flow provides an opportunity for hot water contained within hot water lines to cool over time. When hot water is subsequently called for the cooled water contained within the hot water lines must be discharged through the spout before hot water is reliably delivered through the system. This delay is invariably inconvenient and, in the case of showers, potentially uncomfortable for a bather. 
     Clearly, a method to warm cooled water contained with a hot water line would be of benefit in these situations. 
     SUMMARY OF INVENTION 
     The above shortcoming of residential plumbing systems are addressed in this disclosure. 
     The shower head attachment is used with a shower installed within a residential plumbing system. The shower head attachment is installed in the shower head feed line such that all water released through the shower valve will pass through the shower head attachment. The shower head attachment comprises a perforated tube, an expandable bladder, and a release valve. The release valve is installed between the perforated tube and the shower head. The perforated tube is contained within the expandable bladder such that water flows through perforations formed in the perforated tube will be contained and stored within the expandable bladder. When the release valve is closed and the shower valve is opened, the pressure of the hot water line of the residential plumbing system forces the cooled water stored within the hot water line into the expandable bladder where the cooled water is stored. Once the cooled water is evacuated from the hot water line into the expandable bladder, then the release valve is opened enabling the continued flow hot water into the perforated tube where the hot water mixes with the cooled water stored in the expandable bladder thereby creating a more temperate water temperature that is released through the shower head. 
     These together with additional objects, features and advantages of the shower head attachment will be readily apparent to those of ordinary skill in the art upon reading the following detailed description of the presently preferred, but nonetheless illustrative, embodiments when taken in conjunction with the accompanying drawings.

Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description. 
     Detailed reference will now be made to one or more potential embodiments of the disclosure, which are illustrated in  FIGS. 1 through 4 . 
     The shower head reservoir  100  (hereinafter invention) comprises a perforated tube  101 , an expandable bladder  102 , and a release valve  103 . The release valve  103  is installed between the perforated tube  101  and the shower head  164 . The perforated tube  101  is contained within the expandable bladder  102  such that water flows through a plurality of apertures each of which forms a perforations formed in the perforated tube  101 . The perforated tube is contained and stored within the expandable bladder  102 . The invention  100  is used with a shower installed within a residential plumbing system. The invention  100  is installed in the shower head feed line  163  such that all water released through the shower valve  162  will pass through the invention  100 . When the release valve  103  is closed and the shower valve  162  is opened, the pressure of the hot water line  161  of the residential plumbing system forces the cooled water stored within the hot water line  161  into the expandable bladder  102  where the cooled water is stored. Once the cooled water is evacuated from the hot water line  161  into the expandable bladder  102 , then the release valve  103  is opened enabling the continued flow hot water into the perforated tube  101  where the hot water mixes with the cooled water stored in the expandable bladder  102  thereby creating a more temperate water temperature that is released through the shower head  164  from the release valve  103 . 
     The perforated tube  101  comprises a pipe  111 , a plurality of apertures  112 , a first threaded connection  115  and a second threaded connection  116 . The pipe  111  is further defined with a first end  113  and a second end  114 . The pipe  111  is a hollow cylindrical structure. The first threaded connection  115  is a standard threaded plumbing connection that is formed on the first end  113  of the pipe  111 . The first threaded connection  115  allows the first end  113  of the pipe  111  to be connected to the portion of the shower head feed line  163  that connects the pipe  111  to the shower valve  162 . The second threaded connection  116  is a standard threaded plumbing connection that is formed on the second end  114  of the pipe  111 . The use of the second threaded connection  116  is discussed elsewhere in this disclosure. The plurality of apertures  112  are a plurality of ports that are formed within the cylinder face of the pipe  111 . The plurality of apertures  112  are formed such that water flowing into the pipe  111  from the shower valve  162  can pass through the plurality of apertures  112 . 
     The expandable bladder  102  is an expandable reservoir that is used to enclose the perforated tube  101 . The purpose of the expandable bladder  102  is to store the cooled water contained within the hot water lines  161  when the shower valve  162  is first opened while the release valve  103  discussed below is closed. When this condition occurs, the pressure of the water within the hot water line  161  will force water through the plurality of apertures  112  into the expandable bladder  102 . 
     The release valve  103  is a readily and commercially available valve that can be manually opened and closed. The release valve  103  allows water to flow from the perforated tube  101  to the shower head  164 . The release valve  103  is fitted with a plurality of standard threaded plumbing connections that allows the release valve  103  to be connected to the second threaded connection  116  at the second end  114  of the perforated tube  101  and to the portion of the shower head feed line  163  that connects the pipe  111  to the shower head  164 . In the circumstance where the release valve  103  is closed and the shower valve  162  is open, water will accumulate by design into the expandable bladder  102 . 
     In the first potential embodiment of the disclosure, the perforated tube  101  is a standard plumbing pipe  111  that has the plurality of apertures  112  drilled into the cylinder face of the pipe  111 . The expandable bladder  102  comprises a modification to one or more hydration reservoirs commonly used in outdoor activities. Methods to enclose tubes and pipes within such reservoirs in a water proof manner are well known and documented in the manufacturing arts. The release valve  103  is a readily and commercially available two port inline valve (straight). 
     The invention  100  is capable of being introduced into industrial or commercial applications. The invention  100  is not to be limited to just residential applications. 
     The following definitions were used in this disclosure: 
     Bladder: As used in this disclosure, a bladder is gas impermeable structure. The internal volume of the structure can be varied by: varying the pressure and or quantity of a gas contained within the bladder; or 2) varying the quantity of a liquid contained within the bladder. Bladders are commonly used for storage of a gas or liquid and as a cushion. 
     Cylinder: As used in this disclosure, a cylinder is a geometric structure defined by two identical flat and parallel ends, also commonly referred to as bases, which are circular in shape and connected with a single curved surface, referred to in this disclosure as the face. The cross section of the cylinder remains the same from one end to another. The axis of the cylinder is formed by the straight line that connects the center of each of the two identical flat and parallel ends of the cylinder. In this disclosure, the term cylinder specifically means a right cylinder which is defined as a cylinder wherein the curved surface perpendicularly intersects with the two identical flat and parallel ends. 
     Elastic: As used in this disclosure, an elastic is a material or object that deforms when a force is applied to it and that is able to return to its original shape after the force is removed. A material that exhibits these qualities is also referred to as an elastomeric material. 
     Pipe: As used in this disclosure, a pipe is a hollow cylindrical device that is used for transporting liquids and gases. The line that connects the center of the first base of the cylinder to the center of the second base of the cylinder is referred to as the axis of the cylinder or the centerline of the pipe. When two pipes share the same centerline they are said to be aligned. In this disclosure, the terms inner diameter of a pipe and outer diameter are used as they would be used by those skilled in the plumbing arts. 
     Threaded Connection: As used in this disclosure, a threaded connection is a type of fastener that is used to join a first tube shaped and a second tube shaped object together. The first tube shaped object is fitted with fitted with a first fitting selected from an interior screw thread or an exterior screw thread. The second tube shaped object is fitted with the remaining screw thread. The tube shaped object fitted with the exterior screw thread is placed into the remaining tube shaped object such that: 1) the interior screw thread and the exterior screw thread interconnect; and, 2) when the tube shaped object fitted with the exterior screw thread is rotated the rotational motion is converted into linear motion that moves the tube shaped object fitted with the exterior screw thread either into or out of the remaining tube shaped object. The direction of linear motion is determined by the direction of rotation. 
     Valve: As used in this disclosure, a valve is a device that is use to control the flow of a fluid (gas or liquid) through a pipe.
