Bypass Valve
The bypass valve is typically used to isolate the control valve from the plumbing system’s water pressure in order to perform control
valve repairs or maintenance. The WS1 bypass valve is particularly unique in the water treatment industry due to its versatility
and state of the art design features. The 1” full fl ow bypass valve incorporates four positions, including a diagnostic position that
allows service personal to work on a pressurized system while still providing untreated bypass water to the facility or residence. Its
completely non-metallic, all-plastic design allows for easy access and serviceability without the need for tools.
The bypass body and rotors are glass fi lled Noryl

(or equivalent) and the nuts and caps are glass fi lled polypropylene. All seals are
self-lubricating EPDM to help prevent valve seizing after long periods of non-use. Internal o-rings can easily be replaced if service
is required.
The bypass consists of two interchangeable plug valves that are operated independently by red arrow-shaped handles. The handles
identify the fl ow direction of the water. The plug valves enable the bypass valve to operate in four positions.
1. Normal Operation Position: The inlet and outlet handles point in the direction of fl ow indicated by the engraved arrows
on the control valve. Water fl ows through the control valve during normal operation and this position also allows the
control valve to isolate the media bed during the regeneration cycle. (See Figure 1)
2. Bypass Position: The inlet and outlet handles point to the center of the bypass, the control valve is isolated from the water
pressure contained in the plumbing system. Untreated water is supplied to the plumbing system. (See Figure 2)
3. Diagnostic Position: The inlet handle points in the direction of fl ow and the outlet handle points to the center of bypass
valve, system water pressure is allowed to the control valve and the plumbing system while not allowing water to exit from
the control valve to the plumbing. (See Figure 3)
4. Shut Off Position: The inlet handle points to the center of the bypass valve and the outlet handle points in the direction of
fl ow, the water is shut off to the plumbing system . If water is available on the outlet side of the softener it is an indication
of water bypass around the system (i.e. a plumbing connection somewhere in the building bypasses the system). (See
Figure 4)
