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 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.
The all-plastic design allows for easy access and serviceability without the need for tools. The bypass body and rotors are glass filled Noryl6 (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. 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 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.
- 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.
- Diagnostic Position: The inlet handle points in the direction of flow 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.
- 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
