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 4. Bypass valves allow you to turn off water to the softener for maintenance if needed, but still have water in house pipes.
