REFILLING STORAGE TANK/BREAKING A SALT BRIDGE
WHEN TO REFILL WITH SALT: Check the salt
level a few weeks after you install the softener and
every week after that. Refill when the storage
tank is about 1/3 full. Never let the softener use
all the salt before refilling. Without salt, you will
soon have hard water.
IMPORTANT:
You will have a loss in softening capacity and
may get partly hard water if less than 10
inches of salt is in the storage tank.
PLEASE SEE PAGE 9 FOR SALT FILLING DIRECTIONS.
SALT BRIDGE
Sometimes, a hard crust or salt bridge forms in the
salt storage tank. 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 (melt) in the
water to make brine. Without brine, the resin bed
does not regenerate and you will have hard water.
If the storage 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 asalt bridge.
Salt should be loose all the way to the bottom of
the tank. Hold a broom handle, or like tool, up to
the softener as shown in FIG. 9. Make a pencil
mark on the handle, 1 ″ or 2 ″ below the top height
of the rim. Then, carefully push it straight down
into the salt. If a hard object is felt before the pencil
mark gets to the top of the tank, it's most likely a
salt bridge. Carefully push into the bridge in a few
places to break it. DO NOT TRY TO BREAK THE
SALT BRIDGE BY POUNDING ON THE OUTSIDE
OF THE SALT TANK. YOU MAY DAMAGE IT.
If the wrong kind of salt made the bridge, take it
out. Then fill the tank with nugget or pellet salt
only.
