As a last resort, try adding approximately four (4)
ounces of household bleach (5.25%) into the brine
well. Begin a manual regeneration. Monitor the
drain line for a strong chlorine odour which should
occur in the brine draw cycle . When odour is
present, halt regeneration by unplugging unit and
shutting down water flow to the unit via the bypass
valve. Shutdown the unit for approximately
two (2) hours, then continue regeneration by
plugging unit back in and replacing bypass valve to
service position. Only try this step as a last resort
as chlorine will degrade the resin bed. If
unsuccessful, see next step.
•
Resin bed may have become permanently fouled
due to infrequency of regenerations or nature of
tannins causing colour in water. Replace resin
media bed and check to see that regeneration
frequency is adequate or consult your dealer.
5. Combination Softener filter resin media may be fouled
with Iron. Check visually to confirm.
•
Iron should typically be removed prior to the
unit. Install an iron filter upstream of the unit.
•
Clean iron from resin media bed with a reducing
agent such as sodium bisulfite or sodium
hydrosulfite by adding it to the brine tank down the
brine well and allowing time to mix. Manually
regenerate softener.

softeners.
•
If resin bed cannot be cleaned, it may be
permanently fouled with iron. Replace resin media
bed and install treatment upstream of unit to
remove iron.
6. Combination Softener filter resin media may be fouled
with Calcium Carbonate.
•
Calcium Carbonate fouling is the result of
hardness precipitating onto the resin media.
•
Clean calcium carbonate from resin media with a
mild acid solution such as phosphoric acid. Do this
by adding cleaning product to the brine tank via the
brine well and then manually regenerate. Once
complete, manually regenerate again with salt
brine.
