O-ring used with the Brine Valve Piston Assembly.
There are Two used in the Valve Assembly.
One on the Brine Valve and One in the Hole that the Brine Valve sits inside.
* NOTE: This o-ring, 13302, is also used on the "drain port" between the injector drain module and valve body of the Fleck 9000 model.
One o-ring comes on the Brine Valve Piston Assembly ( 60032 ), and the other would be sitting loose in the bottom of the hole where the Brine Valve is installed.
If the bottom oring is missing or damaged, it will result in water slowly filling the brine tank.
** REPAIR ADVICE:
Perhaps when you replaced the Brine Valve Piston Assembly ( 60032 )
you accidentally pulled out the oring ( 13302 ) that sits in the bottom of the hole
which the valve is installed in. Or at least the oring came out 1/2 way, and you
have jammed the Brine Valve onto the oring and it is not sitting flat.
** Remove the Brine valve and look in the hole for this oring. If you do not see it,
look on the floor around the unit. If you have lost it, you can use the one that is on
your old Brine Valve, as there is another 13302 oring on the Brine Valve
( it is on the white plastic portion of the assembly ).
