Replaced seals and spacers on all valves (calcite, kat1, kat2, carbon, and resin).
Replaced injectors on kat1 and kat2.
Should probably replace seals, spacer, and injectors on these first three tanks every six months.
Need to add calcite (ordered) and centaur carbon (should check when last replaced).
answer: 7000 Centaur Carbon 10x44 Vortech (media replaced June 2018)
Both KatL tanks are now drawing.
Trickle down drain line from calcite tank corrected.
