I've been having a hard time finding which model softener I have. From research the cover looks like a Fleck but the inside workings do not match up with what the Flecks seem look like, sticker says it made in 2004
Definitely a 9000, be aware that the lower piston area was problematic. If you go to rebuild the valve, inspect the lower body for erosion of the metal in the middle of the lower piston area. If it is damaged, you will need to replace the whole valve. Best to upgrade to the 9100. Fleck Valve List | ImpactWaterProducts
