GENERAL WATER SOFTENER MAINTENANCE, continued
CLEANING THE NOZZLE AND VENTURI ASSEMBLY . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
A clean nozzle and venturi is needed for the soft-
ener to work right.
This small unit makes the suc-
tion to move brine from the salt storage area to the
resin tank during regeneration. If it becomes
plugged with sand, silt, dirt, etc., the softener will not
work and you will get hard water.
To get to the nozzle and venturi, remove the softener
top cover. Be sure the softener is in service cycle (no
water pressure at nozzle and venturi). Then, while
holding the nozzle & venturi housing with one hand,
turn off 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. Lubri-
cate the o-ring seal with silicone grease and place
in position. Install and tighten the cap, BY HAND
ONLY. DO NOT OVER TIGHTEN, WHICH MAY
BREAK THE CAP OR HOUSING.
