Claim:
1. A process for providing an overmolded waterway comprising: providing a tube of a first polymeric material having a tube inside dimension at a proximate end, inserting a shaft portion of a sacrificial core into said end of the tube, the shaft portion having a first opening therein, the sacrificial core having a second portion adjacent the end of the tube comprising a second opening and a contact surface about the second opening, the second opening in fluid communication with the first opening and the inside of the tube, positioning at least the end of the tube with the sacrificial core into a mold cavity having a desired shape, positioning a core pin at least partially into the mold cavity transverse to the tube end, the sacrificial core contact surface engaging a mating surface of the core pin closing the second opening, injection overmolding a second polymeric material into the mold cavity over a portion of the tube end and core pin forming a waterway, the overmolded waterway having an outlet portion in fluid communication with the second opening and the inside of the tube, an interface of the sacrificial core contact surface and the mating surface of the core pin inhibiting ingress of molten polymer into the second opening, and removing the core pin from the second opening through the outlet portion and removing the overmolded waterway from the mold cavity, where the sacrificial core second portion includes an extending lip, and the process further comprising
