Sanitizing
A water softener in daily use on a potable water supply generally requires no special attention other than keeping the salt
tank filled� Occasionally, however, a unit may require sanitization under one of the following conditions:
• At start-up time�
• After standing idle for a week or more�
• On private supplies, the appearance of off-tastes and odors, particularly if musty or “rotten egg”
(caused by harmless sulfate-reducing bacteria)�
NOTE! If the water supply contains iron, regenerate the softener before sanitizing to remove iron from the resin.
CAUTION!
Hazard from toxic fumes! Chlorine bleach and common iron control chemicals may generate toxic
fumes when mixed.
CAUTION!
Do not use this procedure if the softener salt contains iron control additives.
If the unit uses any compounds containing sodium hydrosulfite, sodium bisulfite, or any other reducing agent, disconnect
the device feeding the chemical(s) and manually regenerate the unit before sanitizing�
Do not use this procedure if the softener salt contains iron control additives�
1� Remove the brine tank cover�
2� Pour directly into the brine chamber 1/3 to 1/2 cup of unscented 6% household bleach for each cubic foot
of resin in the tank�
3� Manually start recharge� Allow the unit to complete the recharge cycle automatically�
If tastes and odors return frequently, even after sanitization, a continuous chlorination system may be needed�
Send a water sample to a qualified laboratory for bacterial analysis�
