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 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 Noryl 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.
1. 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. (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 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. (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
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)

OEM General Instructions
The control valve offers multiple procedures that allow the valve to be modified to suit the needs of the installation. These
procedures are:
• OEM System Setup
• Installer Displays & Settings (either 1-99 Days Between Regeneration option or 7-Day option)
• User Displays
These procedures can be accessed in any order. Details on each of the procedures are provided below and on the following pages.
When in operation, normal user displays show the time of day or days remaining before regeneration. When stepping through a
procedure if no buttons are pressed within five minutes the display returns to a normal user display. Any changes made prior to the
five minute time out are incorporated.
To quickly exit Installer Displays & Settings or OEM Setup simultaneously press SET HOUR + DOWN. Any changes made prior to
the exit are incorporated.
To reinitialize the control valve check to make sure the valve is in the User Display. Then simultaneously press SET HOUR + DOWN
or unplug power source plug (black wire) on the circuit board, and plug back in.

Installation
Refill Flow Control Assembly or Refill Port Plug
Control valves that are setup for backwash only come equipped with a refill port plug. The refill port plug has no regenerant line
connection.
Control valves that use a regenerant, come equipped with a 3/8” refill flow control assembly. To switch to the ½” refill flow control
assembly, remove the refill flow control and retainer (from the 3/8” refill elbow) by twisting and pulling out. Insert the refill flow
control and retainer into the ½” refill elbow.
To complete the regenerant line connection, orientate the outlet in the desired direction and push the plastic insert into the polytube.
Push the polytube into the nut. Do not use pipe dope or other sealants on threads. The threads for the compression nut do not
need Teflon tape. Tighten the nut securely to create a pressure tight connection. A pliers or crescent wrench may be used to
tighten or unscrew the nut. The nut, gripper and retainer sleeve is a 3 piece assembly that can come apart if removed from the elbow
body. Parts must be reassembled exactly as shown in refill flow control assembly drawing to function properly. If the nut is completely
removed from the body, slip the nut, plastic gripper and retainer sleeve on to the tube then tighten on to the fitting.
Drain Line Flow Control and Fitting Assembly
To determine which drain line flow control to use, obtain media bed expansion tables from the media manufacturer, choose a water
temperature and look up the desired backwash rate per square foot of bed area. Then calculate the backwash rate using the desired
tank diameter. Using Table 5 pick the drain line flow control that has the backwash flow rate closest to the calculated backwash rate.
If a manufacturer chooses to use an external drain line flow control, use a drain elbow fitting that does not contain a hole.
If the drain line is a 5/8” flexible polytube, slide the nut onto the polytube, then place the polytube insert into the end of the polytube
Set Time of Day
STEP 1U – Press SET HOUR
STEP 2U – Current time: Set the clock to the closest hour by using the UP and DOWN button. An
arrow points to PM after 12. After a power outage, the time of day will need to be reset. Press SET
HOUR to exit.
STEP 1U
STEP 2U
Power Loss
If the power goes out current time of day will need to be reset. If the power goes out while the system is regenerating, the cycle picks
up where it was interrupted when the power returns. Note: The display will flash if a power outage has occurred.
Error Message
If “E1,” “E2” or “E3” appears on the display contact the OEM for help. This indicates that the valve
did not function properly.
➟
Manual Regeneration
Sometimes there is a need to regenerate the system, sooner than when the system calls for it, usually referred to
as a manual regeneration. There may be a period of heavy water usage because of guests or a heavy laundry day.
To initiate a manual regeneration at the preset delayed regeneration time, simultaneously press UP +
DOWN buttons together and release. The arrow will point to the word Regen if a regeneration is expected
“tonight.” To cancel the regeneration simultaneously press UP + DOWN buttons and release.
To initiate a manual regeneration immediately, simultaneously press UP + DOWN buttons together for
three seconds. The system will begin to regenerate immediately. The request cannot be cancelled.
Note: For softeners, if brine tank does not contain salt, fill with salt and wait at least two hours before regenerating.

and tighten the nut on to the ¾” drain line fitting. The nut is only designed for use with flexible polytube. Use other nuts if attaching
different materials.
To access the drain line flow control remove the locking clip by pulling it straight out. Pull fitting out and replace the locking clip so
that it is not misplaced. The drain line fitting is pressed in and has an o-ring seal.
In the ¾” elbow, the white flow control retainer is pressed in and has an o-ring seal. The retainer can be removed by rotating and
pulling. The flow control can be removed by prying upward with a small blade flat screwdriver in one of the slots on the side. The
drain line flow control and retainer can be chemically cleaned in dilute sodium bisulfite or vinegar or replaced. Do not use a wire
brush to clean the flow control or the washer. The washers are identified with three numbers, which correspond to the flow rate.
When reinstalling make sure the identifying number and the rounded inside diameter on the washer is visible when seated in the
retainer. The white flow control washer retainer can also be removed and cleaned. Push retainer in firmly when reinstalling.
In the 1” straight fitting, the retainer is the fitting. Unscrew the nut to access the flow control. The drain line flow control and the
fitting can be chemically cleaned or replaced. Do not use a wire brush to clean the flow control or the fitting.
Do not use Vaseline, oils, or other unacceptable lubricants on o-rings. A silicon lubricant may be used on the black o-ring. Use a
pliers or crescent wrench to tighten or unscrew the nut. Do not use a pipe wrench to tighten or loosen nut. Do not use pipe dope or
other sealants on threads. Use Teflon tape on the threads of the drain line control fitting when installing ¾” NPT or 1” straight
fitting.
Installation Fitting Assemblies
The installation fittings connect to the control valve or the bypass valve using nuts that only require hand tightening. Hand tighten
nut connections between control valve and installation fittings, control valve and bypass valve, and bypass valve and installation
fittings allow for easy serviceability. Do not use a pipe wrench to tighten nuts on installation fittings. Hand tighten only.
Split ring retainer design holds the nut on and allows load to be spread over the entire nut surface area reducing the chance for
leakage. The split ring design, incorporated into the installation fittings allows approximately 2 degrees off axis alignment to the
plumbing system. The installation fittings are designed to accommodate minor plumbing misalignments but are not designed to
support the weight of a system or the plumbing.
When assembling the installation fitting package, connect the fitting to the plumbing system first and then attach the nut, split ring
and o-ring. Heat from soldering or solvent cements may damage the nut, split ring or o-ring. Solder joints should be cool and
solvent cements should be set before installing the nut, split ring and o-ring. Avoid getting primer and solvent cement on any part of
the o-rings, split rings, bypass valve or control valve. Solvent cements and primers should be used in accordance with the
manufacturer’s instructions.
Slip the nut onto the fitting first, then the split ring second and the o-ring last. Hand tighten the nut. If the fitting is leaking
tightening the nut will not stop the leak. Remove the nut, remove the fitting, and check for damage or misalignment of the o-ring.
Do not use pipe dope or other sealant on threads. Teflon tape must be used on the threads of the 1” NPT elbow and the ¼” NPT
connection and on the threads for the drain line connection. Teflon tape is not necessary on the nut connection or caps because of
o-ring seals.
Do not use Vaseline, oils, or other unacceptable lubricants on o-rings. A silicon lubricant may be used on black o-rings.
Bypass Valve
The bypass valve easily connects to the control valve body using nuts that only require hand tightening. Hand tighten nut connections
between control valve and fittings, control valve and bypass valve, and bypass valve and installation fittings allow for easy
serviceability. The split ring retainer design holds the nut on and allows load to be spread over the entire nut surface area reducing
the chance for leakage. The split ring design, incorporated into the bypass, allows approximately 2 degrees off axis alignment to the
plumbing system. The bypass is designed to accommodate minor plumbing misalignments but is not designed to support the weight
of a system or the plumbing.
Avoid getting primer and solvent cements on any part of the o-rings or split rings, bypass valve or control valve. Do not use pipe
dope or other sealant on threads. Teflon tape is not necessary on the caps because of o-ring seals.
Do not use Vaseline, oils, or other unacceptable lubricants on o-rings. A silicon lubricant may be used on black o-rings.
