CLEANING THE NOZZLE & VENTURI
A clean nozzle & venturi (See Figure 84) is necessary
for the water softener to work properly. This small unit
creates the suction to move brine from the brine tank
into the resin tank. If it should become plugged with
dirt, silt, sand, etc., the softener will not work and hard
water will result.
To get access to the nozzle & venturi, remove the soft-
ener’s top cover. Put the bypass valve(s) into the
bypass position. Be sure the softener is in the service
cycle (no water pressure at the nozzle & venturi).
Then, holding the nozzle & venturi housing with one
hand, turn the cap to remove it. Do not lose the o-ring
seal. Lift out the screen support and screen. Then,
remove the nozzle & venturi. Wash the parts in warm,
soapy water and rinse in fresh water. If needed, use a
small brush to remove iron or dirt. Be careful not to
scratch, misshape, etc., surfaces of the nozzle & ven-
turi. Also, check and clean the gasket and flow plug(s)
if dirty.
Carefully replace all parts in the correct order.
Lubricate the o-ring seal with silicone grease and put in
place. Install and tighten the cap, by hand only. Do not
overtighten, which could break the cap or housing. Put
the bypass valve(s) into service (softened water) posi-
tion.

RESIN BED CLEANING
If the water supply contains clear water iron, regular
resin bed cleaning is needed to keep the bed from coat-
ing with iron. Use resin bed cleaner, following direc-
tions on the container. Clean the resin every six
months, or more often if iron appears in the softened
water supply.
