I just retired my old Culligan Mark 59 Aqua Sensor which I have had since 1984. I replaced it with a used Mark 100. I picked it up across town and transported it to my home about 35 Miles laying down in my backseat.
After installation, I ran a manual regeneration cycle. I noticed a lot of flakes (rust colored) and I think some resin; a very fine gritty sandy material coming out the discharge tube. I've never handled resin, so I don't really know what it looks like.
Anyway, it is hooked up correctly; in is in and out is out. The amount of material coming out is very sparse and it appears to have diminished during the second regeneration cycle. So, is this normal? Anything I should watch out for or any corrective action to take. Thanks for any replies! Jack
