Bypass Valve - Water Depot PLATINUM SERIES Owner's Manual

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 flow 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 filled Noryl7 (or equivalent) and the nuts and caps are glass filled
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 flow direction of the water. The plug valves enable the bypass
valve to operate in four positions.
Normal Operation Position: The inlet and outlet handles point in the direction of flow indicated by
1.
the engraved arrows on the control valve. Water flows 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)
Bypass Position: The inlet and outlet handles point to the center of the bypass, the control valve
2.
is isolated from the water pressure contained in the plumbing system. Untreated water is supplied
to the plumbing system. (See Figure 2)
Diagnostic Position: The inlet handle points in the direction of flow and the outlet handle points to
3.
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)
Shut Off Position: The inlet handle points to the center of the bypass valve and the outlet handle
4.
points in the direction of flow, 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)
