Water line connection

A by-pass valve system should be installed on all water conditioning systems.
Bypass valves isolate the conditioner from the water system and allow unconditioned
water to be used. Service or routine maintenance procedures may also require that
the system is bypassed. Figure 1 and 2 show the three common bypass methods.
