Piston Assembly
1
The Piston should have a gasket on the shaft side of the flange and a spring pressed onto a boss on the other
side. The gasket should be free of defects such as cuts or debris. The Piston is Teflon coated and should be free of
scratches. The Piston should move freely in the housing; silicone lubrication is recommended on the Piston shaft.
2
O-ring
1
Seals the brine valve to the drive endcap.
3
Housing
1
Should have a Quad-ring for the Piston seal. The Quad-ring (4) is held in place by the brine valve retainer (5). The
brine valve housing has four retaining lugs that secure the brine valve retainer. Just inside the entrance hole for
the Brine Piston (1) is a concave seat area that must be free of defects such as nicks, indentations or debris. If any
defects are detected by visual inspection, repair or replace as needed.
To replace the Quad-ring, it will be necessary to remove the brine valve housing assembly from the drive end cap
(after by-passing and depressurizing the conditioning appliance). Push the piston assembly (1) out of the housing.
To remove the brine valve retainer (5) push in and turn “clockwise” to unlock the retainer. CAUTION! Do not attempt
to remove the retainer with the piston assembly in place. This will damage the housing and/or the retainer. Push
the piston back into the housing to dislodge the old Quad-ring (4) and discard it. Remove the piston, insert the new
Quad-ring and lock the retainer onto the housing by pushing in and turning “counterclockwise” to secure the Quad-
ring. Replace the piston assembly and attach the brine valve assembly to the drive end cap and restore service to
the conditioning appliance.
