Suggested Piping Installations
The piping layouts below depict a traditional three-valve bypass. Culligan also offers an optional bypass valve that con-
nects directly to the inlet and outlet of the water filter.
NOTE Interconnecting pipe and fittings, bypass valves, and isolation valves are not supplied.
CAUTION! DO NOT make a direct connection to the drain. Provide an air gap of at least four times
the diameter of the drain pipe or conform to local sanitation codes and to permit the
observation of drain flow.
NOTE Figure 8 displays externally blocking valves for alternating or progressive flow. Internally blocked pro-
gressive flow is plumbed similarly but without the blocking valves.
