Clack WS 1 water softener valve –parts and operational manual
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 WS 1 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.
It’s 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 0-
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 identity 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.

2. Bypass Position: The inlet and outlet handles point to the center of the
bypass, the control valve in isolated from the water pressure contained in the plumbing system.
Untreated water is supplied to the plumbing system.
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 plumbiiig system while not allowing water to exit from the control valve to the plumbing.
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).

Service Instructions

Drive Assembly
Remove the valve cover to seems the drive assembly
Disconnect the power source plug (black wire) from the PC board prior to disconnecting the motor or
water meter plugs from the PC board. The motor plug connects to the two-pin jack on the left-hand side
of the PC board. The power source plug connects to the four-pinjack. The four-pinjack is between the
two-pin and three-pin jacks. The water meter plug (gray wire) connects to the three-pin jack on the far
right-hand side of the PC board.
The PC board can be removed separately from the drive bracket but it is not recommended. Do not
attempt to remove the display panel from the PC board. Handle the board by the edges. To remove the
PC board from the drive bracket, unplug the power, water meter and motor plugs from the PC board.
Lift the middle latch along the top of the drive bracket while pulling outward on the top of the PC board.
The drive bracket has two plastic pins that fit into the holes on the lower edge of the PC board. Once the
PC board is tilted about 45 from the drive bracket it can be lifted off of these pins. To reinstall the PC
board, position the lower edge of the PC board so that the holes in the PC board lineup with the plastic
pins. Push the top of the PC board towards the valve until it snaps under the middle latch, weave the
power and water meter wires into the holders and reconnect the motor, water meter and power plugs.
The drive bracket must be removed to access the drive cap assembly and pistons or the drive gear cover.
It is not necessary to remove the PC board from the drive bracket to remove the drive bracket. To
remove the drive bracket start by removing the plugs for the power source and the water meter.
Unweave the wires from the side holders. Two tabs on the top of the drive back plate hold the drive
bracket in place. Simultaneously lift the two tabs and gently ease the tap of the drive bracket towards
your body. The lower edge of the drive bracket has two notches that rest on the drive back plate. Lift up
and outward on the drive bracket to disengage
the notches.
To reassemble seat the bottom of the drive bracket so the notches are engaged at the bottom of the
drive back plate. Push the top of the drive bracket towards the two latches. The drive bracket may have
to be lifted slightly to let the threaded piston rod pass through the hole In the drive bracket Maintain a
slight engaging force on top of the drive bracket while deflecting the bracket slightly to the left by
pressing on the side of the upper right corner. This helps the drive gears mesh with the drive cap
assembly. The drive bracket is properly seated when it snaps under the latches on the drive back plate. If
resistance is felt before latching, then notches are not filly engaged, the piston rod is not in hole, the
wires are jammed between the drive bracket and drive buck plate, or the gear is not engaging the drive
cap assembly.
To inspect drive gears, the drive gear cover needs to be removed. The drive gear cover is held in place
on the drive bracket by three clips. The largest of the three clips is always orientated to the bottom of
the drive bracket. Before trying to remove the drive gear cover, the drive bracket must be removed from
the drive back plate. The drive gear cover can be removed from the drive bracket without removing the
motor or the PC board. Simultaneously, push in and down on the large clip at the bottom and the clip on
the left-hand side of the drive bracket behind the PC board. Keep your other fingers behind the drive
gear cover so the drive gears do not drop on the ground.

Replace broken or damaged drive gears. Do not lubricate any of the gears. Avoid getting any foreign
matter on the reflective coating became dirt or oils may interfere with pulse counting.
The drive gear cover only fits on one way, with the large clip orientated towards the bottom. If all three
clips are outside of the gear shroud on the drive bracket the drive gear cover slips easily into place.
The drive bracket does not need to be removed from the drive plate if the motor needs to be removed.
To remove the motor, disconnect the power and motor plugs from the jacks on the PC board. Move the
spring clip loop to the right and hold. Rotate the motor at least a% turn in either direction before gently
pulling on the wire connectors to remove the motor. Pulling directly on the wires without rotating the
motor may break the wires off the motor.
Replace the motor if necessary. Do not lubricate the motor or the gears. When reinstalling the motor
gently turn the motor while inserting so that the gear on the motor meshes with the gears under the
drive gear cover and the small plastic bulge engages one of the slots on the motor housing. Reconnect
the motor plug to the two pronged jack on the lower left hand side of the PC board. If motor will not
easily engage with drive gear when reinstalling, lift and slightly rotate motor before reinserting.
Replace the valve cover. After completing any valve maintenance, press and hold NEXT and REGEN
bottom for 3 seconds or unplug power source jack (black wire) and plug back in. This resets the
electronics and establishes the service piston position. The display should flash all wording, then flash
the soft ware version (e.g. 154) and then reset the valve to the service position.
Drive Can Assembly Main Piston and Regenerant Piston
The drive assembly must be removed to access the drive cap assembly. The drive cap assembly most be
removed to access the piston(s). The drive cap assembly is threaded into the control valve body and
seals with an o-ring. To remove the drive cap assembly use the special plastic wrench or insert a ¼’ to /i
flat bladed screwdriver into one of the slots around the top 2″ of the drive cap assembly so it engages
the notches molded into the drive back plate around the top 2′ of the piston cavity. The notches are
visible through the holes. Lever the screwdriver so the drive cap assembly turns counter clockwise. Once
loosened unscrew the drive cap assembly by hand and pull straight out.

The drive cap assembly contains the drive cap, the main drive gear, drive cap spline, piston rod and
various other parts that should not be dissembled in the field. The only replaceable part on the drive cap
assembly is the 0-ring. Attached to the drive cap assembly is the main piston (down flow or up flow) and
if a regenerant is used, a regenerant piston.
The regenerant piston (the small diameter one behind the main piston) is removed from the main piston
by unsnapping it from its latch. Chemically clean in dilute sodium bisulfite or vinegar or replace the
regenerant piston if needed. To remove the main down flow or up flow piston fully extend the piston
rod and then unsnap the main piston from its latch by pressing on the side with the number. Chemically
clean in dilute sodium bisulfite or vinegar or replace the main piston.
Reattach the main piston to the drive cap assembly. Reattach the regenerant piston (if needed) to the
main piston. Do not lubricate the piston rod, main piston or regenerant piston. Lubricant will adversely
affect the red or clear lip seals. Reinsert the drive cap assembly and piston into the spacer stack
assembly and hand tighten the drive cap assembly. Continue to tighten the drive cap assembly using a
screwdriver as a ratchet until the black o-ring on the spacer stack assembly is no longer visible through
the drain port. Excessive force can break the notches molded into the drive back plate. Make certain
that the main drive gear still turns freely. The exact position of the piston is not important as long as the
main drive gear turns freely.
Reattach the drive assembly to the control valve and connect all plugs. After completing any valve
maintenance, press and hold NEXT and REGEN buttons for 3 seconds or unplug power source jack (black
wire) and plug back in. This resets the electronics and establishes the service piston position. The display
should flash all wording, then flash the soft ware version (e.g. 154) and then reset the valve to the
service position.
spacer stack assembly
To access the spacer slack assembly remove the drive assembly, drive cap assembly and piston. The
spacer stack assembly can be removed easily without tools by using thumb and forefinger. Inspect the
black 0-rings and red or clear lip seals for wear or damage Replace the entire stack if necessary. The
spacer stack assembly has been 100% tested at the factory to insure proper orientation of one way
seals. Do not disassemble the stack.
The spacer stack assembly maybe chemically cleaned (dilute sodium bisulfite or vinegar) or wiped with a
soft cloth.
The spacer stack assembly can be pushed in to the control valve body bore by hand. Since the spacer
stack assembly can be compressed it is easier to use a blunt object (5/8″ to 1-1/8″ in diameter) to push
the center of the assembly into the control valve body. –The assembly is properly seated when at least
four threads are exposed (approximately 5/8″). Do not force the spacer stack assembly in. The control
valve body bore interior can be lubricated with silicone to allow for easy insertion of the entire stack. Do
not use silicone or any other type of lubricant on the red or clear lip seals or the piston.
Reattach the drive cap assembly and piston(s) and the drive assembly.

After completing any valve maintenance, press and hold NEXT and REGEN buttons for 3 seconds or
unplug power source jack (black wire) and plug back in. This resets the electronics and establishes the
service piston position The display should flash all wording, then flash the soft ware version and then
reset the valve to the service position.
Injector Can. Screen Injector Plug and Injector
Unscrew the injector cap and lift off. Loosen cap with special plastic wrench or pliers if necessary.
Attached to the injector cap is a screen. Remove the screen and clean if fouled.
The plug and/or injector can be pried Out with a small screwdriver. The plug can be wiped clean. If the
plug leaks replace the entire plug. The injector consists of a throat and a nozzle. Chemically clean the
injector with vinegar or sodium bisulfite. The holes can be blown out with air. Both pieces have small
diameter holes that control the flow rates of water to insure that the proper concentration of
regenerant is used. Sharp objects, which can score the plastic, should not be used to clean the injector.
Scoring the injector or increasing the diameter of the hole could change the operating parameters of the
injector.
Two holes are labeled DN and UP. Check for compliance with one of the following:
for down flow systems, the appropriate size injector in located in the “DM’ hole, a plug is in the “UP”
hole and that the piston is a combination of the down flow main piston and the regenerant piston.
for up flow systems, the appropriate size injector is located in the “UP” hole, a plug is in the “Whole and
that the piston is a combination of the up flow main piston and the regenerant piston; or
for backwash only systems, a plug is in the “DN” hole and in the “UP” hole, and that the piston only has
a down flow main piston (the regenerant piston must be removed) and a plug is in the refill flow control
position.
Push the plug(s) and/or injectors firmly in place, replace the screen and hand tighten the injector cap.
Refill Flow Contrpl Assembly or-Refill Port Plug
To clean or replace the refill flow control, pull out the elbow-locking clip and then pull straight upon the
elbow. Replace the elbow locking clip in the slot so that it is not misplaced. Twist to remove the white
flow control retainer. The flow control can be removed by prying upward through the side slots of the
retainer with a small blade flat screwdriver.
Chemically clean the flow control or the white flow control retainer using dilute sodium bisulfite or
vinegar. Do not me a wire brush. If necessary, replace the flow control, wring on the flow control
retainer, or the 0-ring on the elbow.
Reseat the flow control so the rounded end is visible in the flow control. Reseal the white flow control
retainer by pushing the retainer into the elbow until the wring seats. Remove locking clip, push down on
elbow to reseat and insert locking clip.
Do not use Vaseline, oils, or other unacceptable lubricants on o-rings. A silicon lubricant may be used on
the n-ring on the elbow or the white retainer.
Water Meter or Meter Plug

The water meter assembly is connected to the PC board by a wire. If the entire water meter assembly is
to be replaced, remove the control valve cover and remove the power source and water meter plugs
from the PC board. Unlatch the drive assembly and lean it forward. Unthread the water meter wire from
the side of the drive assembly and through the drive back plate. To reinstall, rethread the water meter
wire through the drive back plate and the side of the drive assembly. Reattach the drive assembly and
the water meter and power plugs.
If no water meter wire is visible, then a plug is installed not a water meter.
The water meter wire does not need to be removed from the PC board if the water meter is only being
inspected and cleaned. To remove the water meter assembly, unscrew the meter capon the left side of
the control valve. Pliers maybe used to unscrew the nut if necessary.
With the nut removed, a slot at the top of the water meter is visible. Twist a flat blade screwdriver in the
slot between the control valve body and the meter. When the meter is part way out it is easy to remove
the water meter from the housing. Once the water meter is removed from the control valve body, use
your fingers to gently pull forward on the turbine to remove it from the shaft.
Do not use a wire brush to clean. Wipe with a clean cloth or chemically clean in dilute sodium bisulfite or
vinegar. The turbine can be immersed in the chemical. Do not immerse electronics. If the turbine is
scored or damaged or the bearings on the turbine are worn replace the turbine.
Do not lubricate the turbine shaft. The turbine shaft bearings are prelubricated Do not use Vaseline, oils,
or other unacceptable lubricants on the o-ring. A silicon lubricant may be used on the black 0-ring.
Snap the turbine on the shaft and reinsert the water meter into the side slot. Hand tighten the nut. Do
not use a pipe wrench to tighten nut.
Bypass Valve
The working parts of the bypass valve are the rotor assemblies that are contained under the bypass
valve caps. Before working on the rotors, make sure the system is depressurized. Turn the red arrow
shaped handles towards the center of the bypass valve and back to the arrow direction several times to
ensure rotor is turning freely.
The nuts and caps are designed to be unscrewed or tightened by hand. If necessary a pliers can be used
to unscrew the nut or cap. Do not uses pipe wrench to tighten or loosen nuts or caps. Do not place
screwdriver in slots on caps and/or tap with a hammer.
To access the rotor, unscrew the cap and lift the cap, rotor and handle Out as one unit. Twisting the unit
as you pull it out will help to remove it more easily. There are three 0-rings: one under the rotor cap,
one on the rotor stem and the rotor seal. Replace worn 0-rings. Clean rotor. Reinstall rotor.
When reinstalling the red arrow handles be sure that:
0-rings on both rotors face to the right when being viewed from the front of the control valve when the
handle pointers are lined up with the control valve body arrows; or
2 Arrows point toward each other in the bypass position.

Since the handles can be pulled off, they could be accidentally reinstalled I 80°° from their correct
orientation. To install the red arrow handles correctly, keep the handles pointed in the same direction as
the arrows engraved on the control valve body while tightening II bypass valve caps.
After completing any valve maintenance, press and hold NEXT and REGEN buttons for 3 seconds or
unplug power source jack (black wire) and plug back in. This resets the electronics and establishes the
service piston position. The display should flash all wording, then flash the software version (e.g. 154)
and then reset the valve to the service pdsition.
