Routine Maintenance
BREAKING A SALT BRIDGE
Sometimes, a hard crust or salt bridge forms
in the salt storage area. It is usually caused
by high humidity or the wrong kind of salt.
When the salt bridges, an empty space forms
between the water and salt. Then salt will not
dissolve in the water to make brine.
If the brine tank is full of salt, it is hard to tell if
you have a salt bridge. Salt is loose on top, but
the bridge is under it. The following is the best
way to check for a salt bridge.
Salt should be loose all the way to the bottom
of the tank. Take a broom handle or like tool,
and carefully push it down into the salt, working
it up and down. If the tool strikes a hard object
(be sure it's not the bottom or sides of the
tank), it's most likely a salt bridge. Carefully
break the bridge with the tool. Do not pound on
the walls of the tank.
bridge pour one gallon of warm water (not hot)
into the tank.
If the wrong kind of salt made the bridge, take it
out. Then fill the tank with nugget or pellet salt
only. In humid areas, it is best to fill with less
salt, more often to prevent a salt bridge from
forming.
