Replaced RESIN and CALCITE.
Iron problems continued as detected via toilet reservoirs.
Noted a surge of iron on first opening J bath spigot.
Could this be a regeneration issue? Otherwise water appears good.
Replaced fine mesh resin. Valve appeared very clean.
Cleaned and replaced calcite. Valve appeared iron coated, but otherwise normal.
PotPerm and salt being utilized normally.
Will check programming information and valve cycling.
