ABSTRACT:
A valve for use with a water filtration system has a housing and a piston contained therein. The piston has a bypass position, a shut-off position, an inservice position, and a back-flush function in relation to the housing. These functions are accomplished by maneuvering a cylinder inside a housing in a manual fashion with the appropriate handle. The housing has various ports which contact various apertures within the cylinder to provide for such a flow.
