Refill Flow Control Assembly or Refill Port Plug
To clean or replace the refill flow control, pull out the elbow-locking clip and then pull straight up on 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 flat blade screwdriver.
Chemically clean the flow control or the white flow control retainer using dilute sodium bisulfite or vinegar. Do not use a wire brush.
If necessary, replace the flow control, o-ring on the flow control retainer, or the o-ring on the elbow.
Reseat the flow control so the rounded end is visible in the flow control. Reseat the white flow control retainer by pushing the
retainer into the elbow until the o-ring 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 silicone lubricant may be used on the o-ring on the elbow or
the white retainer.
Meter Plug
This control valve does not come equipped with a meter, instead a plug is installed. The plug should not need to be serviced.
To remove the meter plug assembly, unscrew the meter cap on the left side of the control valve. Pliers may be used to unscrew the
nut if necessary.
With the nut removed, a slot at the top of the meter plug is visible. Twist a flat blade screwdriver in the slot between the control
valve body and the meter plug. When the meter plug is part way out it is easy to remove the meter plug from the housing.
Do not use a wire brush to clean the meter plug. Wipe with a clean cloth or chemically clean in dilute sodium bisulfite or vinegar.
Do not use Vaseline, oils, or other unacceptable lubricants on the o-ring. A silicone lubricant may be used on the black o-ring.
Reinsert the meter plug into the side slot. Hand tighten the nut. Do not use a pipe wrench to tighten nut.
