Abstract

A float-controlled, ball cock assembly comprises an improved two-piece valve useful with either a fixed height or an adjustable height riser. The two-piece valve includes a resilient valve seal element and a rigid valve cap fitted together to form an annular chamber therebetween. A rigid spacer sleeve is positioned in the chamber to limit the movement of the valve seal element between the closed position in contact with a valve seat and the open position spaced from the valve seat. The adjustable height riser includes inlet and outlet tubes, each composed of two parts telescopically engaging one another. Adjustment of the height of the riser is achieved by the use of one or more T-shaped tabs which are secured by a lock collar threaded onto the outer of the two telescoping outlet tubes and which can be moved locking into and out of engagement with radially extending grooves on the outer surface of the inner outlet tube.
