     BACKGROUND OF THE INVENTION 
     The following includes information that may be useful in understanding the present invention(s). It is not an admission that any of the information provided herein is prior art, or material, to the presently described or claimed inventions, or that any publication or document that is specifically or implicitly referenced is prior art. 
     1. Field of the Invention 
     The present invention relates generally to the field of draining means and more specifically relates to efficient drain systems for use with substantially contained volumes of fluids. 
     2. Description of the Related Art 
     Storage of liquids, solids and gases (fluids) may be provided by large containers. Fluids may be transported between locations via piping infrastructure or by large moveable containers such as those pulled by highway tractors. In certain instances such as during maintenance (shutdowns), cleaning or other tasks the fluids may need to be drained. In order to effectively drain large, closed containers, users may be required to use pumps or other types of cumbersome equipment. This can be a laborious, inconvenient, and a costly task. Other methods for extracting liquids from large containers may require users to cut tees into large pipes and weld steel fittings to the containers, which can also be expensive and time-consuming. Individuals who work in industrial settings, farms, or who need frequent access to the contents of the tanks for their homes, may benefit from a convenient, efficient solution. 
     Various attempts have been made to solve the above-mentioned problems such as those found in U.S. Pat. No. 7,597,361; Pub No. 2004/0265091; U.S. Pat. Nos. 5,439,256; 5,129,684; 6,681,796; and 7,552,742. This prior art is representative of draining means. None of the above inventions and patents, taken either singly or in combination, is seen to describe the invention as claimed. 
     Ideally, an efficient drain system should be user-friendly, safe in-use and, yet would operate reliably and be manufactured at a modest expense. Thus, a need exists for a reliable efficient drain system to avoid the above-mentioned problems. 
     BRIEF SUMMARY OF THE INVENTION 
     In view of the foregoing disadvantages inherent in the known draining device art, the present invention provides a novel efficient drain system. The general purpose of the present invention, which will be described subsequently in greater detail is to provide safe, efficient draining means for contained and substantially contained fluids. 
     The present invention allows users to easily drain large containers, such as tanks, barrels, drums, and pipes which are used to hold liquids. This innovative product preferably features a draining pipe with an attached dispensing valve, which can be installed into a hole that is drilled into the desired container. After installation, consumers may simply turn the dispensing valve to release desired amounts of liquid/gas/semi-solid(s). Using this product may eliminate the need for using pumps, or for welding or cutting tees into pipes, in order to effectively drain large containers or piping systems. It may be ideal for use in residential homes, farms, and industrial establishments. 
     An efficient drain system is disclosed herein, in a preferred embodiment comprising a fluid valving assembly. The fluid valving assembly comprises a threaded valved faucet having; a handle comprising a wheel handle; a stem; a threaded spindle; a packing nut; a packing; a seat washer; and a valve seat; a threaded nut comprising an IP nut; a first and second washer, (the first washer is rigid and the second washer comprising rubber); a threaded nipple; at least two bracing members acting as retaining plates. The bracing members comprise a first bracing member; and a second bracing member. The present invention also comprises a through-fastener comprising a retainer pin; 
     The threaded valved faucet is operatable to allow and restrict fluid-flow via the handle. The handle is coupled to said stem; the stem passing through the packing nut and the packing. The threaded spindle is able to be manipulated by the handle via the stem such that the seat washer is able to contact the valve seat in a closed condition wherein fluid is prevented from flow. When the seat washer is not in contact with the valve seat provides that the fluid is able to (free) flow through a flow opening located in the valve seat. 
     The packing nut and packing provide sealing to contain the fluid from escaping adjacent the stem. The threaded nut is preferably coupled between the first washer and the threaded valved faucet onto the threaded nipple such that the threaded valved faucet is able to be seal-inserted through a container-aperture in a fluid container. The second washer comprising rubber is located about the threaded nipple in series, the first washer located on an outside of the fluid container acting as a gasket and the second washer located on an inside of the fluid container in series about the threaded nipple. The first and second washers comprises surface area increasers to decrease strain (distribute fluid load) on the container-aperture in the fluid container. The container-aperture comprises about a 1⅜″ hole drilled into the fluid container in preferred embodiments. 
     The threaded valved faucet is coupled in fluid communication with the threaded nipple, the threaded nipple accessing an inner volume located in the inside of the fluid container and the threaded valved faucet located adjacent the outside of the fluid container. The two bracing members are preferably located vertically within the fluid container acting as surface area supports. The through-fastener comprises a retainer pin in preferred embodiments which is insertable (sequentially) through a first orifice in the first bracing member, a through-hole in the threaded nipple, and a second orifice in the second bracing member; the first bracing member and the second bracing member acting as the retaining plates coupled in combination with the threaded nipple to maintain relative static positioning of the fluid valving assembly in relation to the fluid container. The fluid container may be a pipe and may comprise other containment means such as barrels, tanks and the like in closed and/or open systems. 
     The threaded valved faucet of the fluid valving assembly comprises outer threads such that a hose may be coupled thereto to remotely drain the fluid; wherein the fluid is a flowable liquid. The hose may comprise rigid piping if desired. The threaded valved faucet is horizontally installable in the fluid container through the container-aperture, the container-aperture located a distance from a bottom of the fluid container such that sediment located in the fluid container doesn&#39;t enter and obstruct (plug off) the threaded nipple. The threaded valved faucet is removably inter-changeable if desired. In this way the fluid valving assembly, as coupled to the fluid container, is able to be manipulated by an operator to drain the fluid located in the fluid container in a controlled fashion. 
     A method of use for an efficient drain system is also disclosed herein comprising the steps of: installing a fluid valving assembly through a container-aperture into a fluid container; sealing the fluid valving assembly to the fluid container; filling at least one fluid into the fluid container; and controllably-draining a desired amount of the at least one fluid using the fluid valving assembly during a maintenance period, the fluid valving assembly in an open condition; wherein the fluid container when closed is able to maintain a closed system thereby preventing a need for disassembly. Other installations may be used. 
     The present invention holds significant improvements and serves as an efficient drain system. For purposes of summarizing the invention, certain aspects, advantages, and novel features of the invention have been described herein. It is to be understood that not necessarily all such advantages may be achieved in accordance with any one particular embodiment of the invention.
