         2 . The water bottle cap assembly of  claim 1 , wherein the engageable member comprises internal threads. 
     
     
         3 . The water bottle cap assembly of  claim 1 , further comprising a ring-shaped sealing member disposed within the cap and configured to facilitate engagement with the water source. 
     
     
         4 . The water bottle cap assembly of  claim 1 , wherein the cap is configured to accommodate a volume of air between a maximum water level height and an interior of the dome-shaped outer surface of the cap. 
     
     
         5 . The water bottle cap assembly of  claim 1 , wherein the filter comprises pores of about 0.1 micron. 
     
     
         6 . The water bottle cap assembly of  claim 1  wherein the filter is a hydrophobic filter. 
     
     
         7 . The water bottle cap assembly of  claim 1 , further comprising a check valve disposed within at least one of the tubular members and configured to prevent fluid flow into the gas source. 
     
     
         8 . The water bottle cap assembly of  claim 1 , wherein the cap comprises two, three, or four ports. 
     
     
         9 . The water bottle cap assembly of  claim 1 , wherein at least one of the tubular members comprises a dual-lumen tubular member such that an inner tube extends within an outer tube. 
     
     
         10 . The water bottle cap assembly of  claim 1 , wherein the water bottle cap assembly is formed of a sterilizable polymeric material. 
     
     
         11 . A water bottle cap assembly for use with an endoscopic device, the assembly comprising:
 a cap comprising an engageable member configured to sealingly engage with a water source, wherein the cap defines four ports, the four ports opening into a fluid storage chamber defined by the water source and the cap;   the fluid storage chamber configured to accommodate a volume of air between a maximum water level height of the water source and an interior of the cap, wherein each of the four ports is initially sealed off with a removable sealing member to prevent fluid through the associated port, and wherein each of the removable sealing members comprise at least one of a peelable material and a pierceable material;   a plurality of tubular members, each tubular member coupled to a respective port so as to be in fluid communication therewith, at least one of the tubular members being a single lumen tubular member comprising a coupling member configured to couple to a gas source;   an adaptor coupled to an end of one of the tubular members and configured to engage with an endoscopic device, at least one of the tubular members configured to convey at least one fluid between the water source and the endoscopic device; and   a filter disposed on the single lumen member closer to the cap than the coupling member to filter contaminants from entering the water source and to prevent backflow to the gas source, wherein the volume of air allows a pressure level of the water source to be increased to a level sufficient for conveying the at least one fluid from the water source through at least one of the tubular members.   
     
     
         12 . The water bottle cap assembly of  claim 11 , wherein the cap comprises a dome-shaped outer surface. 
     
     
         13 . The water bottle cap assembly of  claim 11 , wherein the filter comprises pores of about 0.1 micron. 
     
     
         14 . The water bottle cap assembly of  claim 11 , wherein the filter is a hydrophobic filter. 
     
     
         15 . A water bottle cap assembly for use with an endoscopic device, the assembly comprising:
 a cap comprising an outer surface, an inner surface, a sealing member configured to absorb slack between the inner surface and a water bottle, and a gripping surface covering at least a portion of the outer surface, wherein the sealing member and the gripping surface are integrally formed;   a plurality of ports between the outer surface and the inner surface of the cap;   a plurality of tubular members, wherein each tubular member is coupled to a respective port so that each tubular member is fluidly coupled to the respective port, wherein at least one tubular member comprises a coupling member for coupling to a gas source;   an adaptor coupled to an end of one of the tubular members and configured to engage with an endoscopic device; and   a filter disposed on the at least one tubular member with the coupling member for coupling to a gas source.
