Plan the Installation
INLET - OUTLET PLUMBING OPTIONS
Always install either a single bypass valve (provided)
or, if desired, parts for a 3 valve bypass system (not
included) can be purchased and assembled, as shown
in Figure 6. Bypass valves allow you to turn off water
to the Central Water Filtration System for maintenance
if needed, but still have water in house pipes.
Use either:
Copper pipe
Threaded pipe
PEX (Crosslinked Polyethylene) pipe
CPVC plastic pipe
Other pipe approved for use with potable water
