Sanitizing

Procedure

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:

t At start-up time.

t After standing idle for a week or more.

t 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! Caution! Hazard from toxic fumes! Chlorine bleach and

common iron control chemicals may generate toxic fumes

when mixed.

If the unit uses Culligan Sofner-gard® or other 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 common household bleach (5.25%

sodium hypochlorite) 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.
