Routine Maintenance.

CLEANING THE NOZZLE AND VENTURI ASSEMBLY
A clean nozzle and venturi is needed for the water
softening system to work properly. This small
unit makes the suction to move brine from the salt
storage area to the resin tank during recharge. If
it becomes plugged with sand, dirt, etc., the water
softening system will not work and you will get hard
water.
To get to the nozzle and venturi, remove the water
softening system top cover. Be sure the water
softening system is in service cycle (no water
pressure at nozzle and venturi). Then, while holding
the nozzle and venturi housing with one hand,
remove the cap. Lift out the screen support and
screen, then the nozzle and venturi. Wash and rinse
the parts in warm water until clean. If needed, use
a small brush to remove iron or dirt. Also check and
clean the gasket.
NOTE: Some models have a small flow plug located
in the nozzle and venturi, and/or a small cone
shaped screen in the housing. Be sure to check and
clean these parts, if your model is so equipped.
Carefully replace all parts in the correct order. Lightly
lubricate the o-ring seal with clean silicone grease
or petroleum jelly and place in position. Install and
tighten the cap, by hand only. Do not overtighten
the cap.
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. To help dissolve
the salt 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.
