1. A valve for a water filtration system having a housing and a piston contained within the housing, comprising:
- a) the housing having a series of ports including upper ports in a side thereof and lower ports in a base thereof;
b) the piston having a series of apertures to cooperate with the upper ports;
c) the piston being movable within the housing about a piston axis;
d) the series of apertures, the series of lower ports and the series of upper ports cooperating to form a first position, a second position, a third position and a fourth position;
e) the series of apertures including a first aperture, a second aperture, a third aperture and a fourth aperture;
f) the series of lower ports including a first lower port, a second lower port, a third lower port and a fourth lower port;
g) the series of upper ports including a first upper port, a second upper port, a third upper port and a fourth upper port;
h) the first upper port, the first lower port, and the first aperture cooperating to form a first position to serve as a bypass position;
i) the second upper port, the second lower port, and the second aperture cooperating to form a second position to serve as a shut-off position;
j) the third upper port, the third lower port, and the third aperture cooperating to form a third position to serve as a filter position;
k) the fourth upper port, the fourth lower port, and the fourth aperture cooperating to form a fourth position to serve as a shutoff position;
l) the bypass position serving to cause the water filtration system to be bypassed;
m) the shut-off position serving to cause the water filtration system to be shutoff;
n) the filter position serving to cause the water filtration system to operate; and
o) the back-flush function serving to cause the water filtration system to be reactivated.

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.

18. A valve for a filtration cylinder for a water system having a housing and with a piston contained therein, comprising:
-
a) the housing having a series of ports including upper ports and lower ports; b) the piston having a series of apertures; c) the piston having a movement within the housing about an axis; d) the upper ports having a female threaded arrangement for attachment to a water system; e) the lower ports being adjacent to an exterior male threaded portion for attachment to the filter; f) the apertures and the ports cooperating to form a bypass position, a shut-off position, a filter position, and a back-flush function for the piston in relation to the housing; g) the movement being rotation of the piston within the housing about an axis; h) the piston being movably mounted within the housing; i) the housing having a piston receiving aperture therein; j) the housing having a back-flush port therein as one of the upper ports; k) the housing having a pass through port therein as one of the upper ports; l) the piston receiving aperture having a piston axis; m) the back-flush aperture having a back-flush axis; n) the pass through aperture having a pass through axis; and o) the piston axis, the back-flush axis and the pass through axis being mutually perpendicular.
