Abstract

Flexible assembly facilitating members attached to the valve body of a relief valve for a fluid treatment assembly, such as a fluid filter assembly, serve to maintain the valve components as a unit prior to assembly of the valve into the fluid filter assembly. During final assembly of the filter assembly the assembly facilitating members are biased into an inoperative position whereby operation of the valve is not dependent upon the assembly facilitating members.
