1. Normal Operation Position: The inlet and outlet handles point in the direction of flow indicated by the
engraved arrows on the control valve. Water flows through the control valve for normal operation of a
water softener or filter. During the regeneration cycle this position provides regeneration water to the
unit, while also providing untreated water to the distribution system. (Fig. 1)
2. Bypass Position: The inlet and outlet handles point to the center of the bypass. The system is
isolated from the water pressure in the plumbing system. Untreated water is supplied to the building.
(Fig 2)
3. Diagnostic Position: The inlet handle points toward the control valve and the outlet handle points to
the center of bypass valve. Untreated supply water is allowed to flow to the system and to the building,
while not allowing water to exit from the system to the building. (Fig. 3) This allows the service
technician to draw brine and perform other tests without the test water going to the building.
NOTE: The system must be rinsed before returning the bypass valve to the normal position.
4. Shut Off Position: The inlet handle points to the center of the bypass valve and the outlet handle
points away from the control valve. The water is shut off to the building. The water treatment system
will depressurize upon opening a tap in the building. A negative pressure in the building combined with
the softener being in regeneration could cause a siphoning of brine into the building. If water is
available on the outlet side of the softener it is an indication of water bypassing the system (Fig. 4) (i.e.
a plumbing cross-connection somewhere in the building).
