Compact aircraft galley plumbing system

Abstract

An aircraft galley plumbing is disclosed comprising water distribution components and assemblies to allow installation in a wet/refrigerated reduced foot print galley. The system includes a single potable water distribution manifold with quick disconnect couplings for the GAINS and built in air bleed devices facilitate rapid drainage and easy installation. The system also includes a compact pressure check valve to control filling operation and drain down of the potable water system. The use of a compact air stop valve and integrated master distribution block (manifold) and water filter system further enhance the system.

I claim: 
     
         1 . A plumbing system for an aircraft galley, comprising:
 a potable water distribution manifold having quick disconnect couplings for associated GAINS, the potable water distribution manifold further comprising air bleed devices for facilitating rapid drainage;   a compact pressure check valve to control a filling operation and a drain down of circulating potable water;   a compact air stop valve for controlling flow through the plumbing system;   an integrated master distribution manifold coupled to a water filter system; and   a supply conduit system and a drainage conduit system for supplying and draining water, respectively.   
     
     
         2 . The plumbing system of  claim 1 , wherein potable water is supplied to the plumbing system from above. 
     
     
         3 . The plumbing system of  claim 1 , wherein potable water is supplied to the plumbing system from below. 
     
     
         4 . The plumbing system of  claim 1 , further comprising a surface mounted sink and sink drainage line. 
     
     
         5 . The plumbing system of  claim 1 , further comprising an air stop valve manual override mechanism. 
     
     
         6 . The plumbing system of  claim 1 , further comprising a pair of filtration units. 
     
     
         7 . The plumbing system of  claim 6 , wherein venting partially occurs when air is forced through the filtration units. 
     
     
         8 . The plumbing system of  claim 6 , wherein one line from the filtration units feeds the potable water distribution manifold and a second line supplies water to a potable water faucet. 
     
     
         9 . The plumbing system of  claim 1 , further comprising a remote emergency potable water shut off valve. 
     
     
         10 . The plumbing system of  claim 1 , further comprising a backflow prevention valve manual override controlled by a cable.
