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. Refer to
. 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 or filter it is an indication of
water bypassing the system. Refer to
. (i.e. a plumbing cross-connection somewhere in the building).
