We have an eight-year-old Culligan Soft-Minder Twin with a Fleck 9100 control valve. The upper valve assembly is leaking at the piston.
Several years ago on this forum, it was suggested that the seal kits and the piston assemblies be replaced. However, I think I take issue with the need to replace the piston assemblies. It would seem to me that the pistons should sustain NO wear since they ride within the seals and have no contact with the inner wall of the cylinder. Is that not correct?
I should add that my wife and I are in our seventies and use very little water. The Fleck controller only cycles about once every two-to-three-weeks which means that, in the eight years it's been in service, it has only cycled a total of about 160 times.
As to the disassembly to replace the seal kits, it would appear rather straightforward. However, I would like to know if there are any stumbling blocks along the way a novice should know about?
As for specific replacement parts (from Softenerparts.com) is anything needed other than the two seal and spacer kits?
To summarize my questions:
1) Are new piston assemblies needed?
2) Tricks and tips for disassembly/reassembly.
3) Assuming the old piston assemblies can be used, are there any other parts likely to be required?
Thanx, guys!
