Brine Valve Housing Assembly
93260 Housing:
Should have a Quad-ring for the Piston seal. The Quad-ring (4) is held in
place by the quad ring retainer (5). The brine valve housing has four retaining lugs that secure
the quad ring 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 quad ring 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 "counter-
clockwise" 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.
93243-JG Housing Cap:
The Cap is held in place by two 5/8" machine screws that engage the
Housing flange. An 0-ring seals the Cap and Housing. Place the 0-ring into the housing open-
ing, lubricate with silicone grease and then using a twisting action, pressure insert the Cap.
CAUTION: The 3/8" locking ring (8) must be installed to prevent air from being drawn into the
appliance during brine rinse.
90843 .5 gpm Flow Control:
The Flow Button has two distinct and different sides. One is
"flat"; the other is "concave". The button should be centered in the housing opening with the
four locator "ribs" with the concave side facing the Housing Cap.
93620 Brine Piston:
The Piston should have an 0-ring on the shaft side of the flange and a
spring pressed onto a boss on the other side. The 0-ring should be free of defects such as cuts
or debris on the shaft side. The Piston is Teflon coated brass and should be free of scratches.
The Piston should move freely in the housing; silicone lubrication is not recommended on the
Piston shaft.
