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.
