BYPASSING THE WATER CONDITIONING SYSTEM BYPASSING THE WATER CONDITIONING SYSTEM
A bypass should be installed on all water conditioning
systems. A bypass isolates the conditioner from the water
system and allows unconditioned water to be used while
the conditioner is undergoing service or maintenance
procedures or if the conditioner is experiencing
performance issues. Figures 8 and 9 show the most
common bypass methods.
Knob Style Plastic Bypass Valve
This type of bypass is located directly behind the conditioner
valve on top of the media tank. To bypass the conditioner
system using this type of bypass, turn both of the knobs
on the sides of the bypass clockwise until the holes in the
knobs are facing up as shown in Figure 8 Knob Style Plastic
Bypass Valve.
To return the conditioner system to regular service, turn
both of the knobs on the bypass counter-clockwise back to
their original positions.

(See Figure 9 Manual Bypass).
