    Abstract: A two-part bottle water delivery system. A separate pump unit (84) snaps into a typical commercial water bottle (86). The bottom draw pump (18) is shaft driven (14). The separate placement of pump (18), feedline (32), drive shaft (14), and drawlines (22) into the bottle (86) allows all water contact items to be submitted to the commercial bottle cleaning and sterilization process. This assures maximum purity within the typical sealed plastic cap. The corresponding control/motor (82) automatically activates by switch (42) upon insertion into bottle (86). Water flow control is upon demand by pressure switch (34). Control/motor (82) and pump unit (86) are designed with exact one position alignment. Dispensing is accomplished by a reversible mounting (78) self-adhering (68) valve (80) incorporating a flat tube (54) capable of bypassing the typical magnet seal (56) on a conventional refrigerator. The seal is maintained and tube protected by a bridge (66).
