1. A system for treating water, said system comprising:
- a water treatment reservoir;
an electronic programmable controller, said programmable controller capable of displaying visual indicators on an output display screen and capable of receiving input from a plurality of push buttons; and
a valve body comprising;
a fluid inlet port;
a first fluid outlet port;
a second fluid outlet port;
a first fluid inlet/outlet port;
a second fluid inlet/outlet port;
a third fluid inlet/outlet port; and
a piston rod selectively positionable by said programmable controller to direct fluid flow between said ports to execute a regeneration cycle comprising at least one stage selected from the group consisting of;
backwash, down brine, up brine, softening, rinse, service, and brine tank fill,wherein said programmable controller and said valve body are coupled to and supported by said reservoir,wherein said fluid inlet is in fluid communication with a water source;
wherein said first fluid inlet/outlet port and said second fluid inlet/outlet port are in fluid communication with said reservoir, andwherein said third fluid inlet/outlet port is in fluid communication with a brine tank.

Abstract
A system for fluid treatment that provides alternative regeneration cycles within the same fluid treatment device. A second alternative regeneration cycle is available within the same device, which has independent cycles or processes from the first regeneration cycle. The first and second regeneration cycles can be programmed at the same time and be programmed to alternatively run based upon the number of individual cycles run, the time the cycles have run, the amount of fluid that has passed through the device, or the concentration of brine and/or chlorine in the fluid within the device.
