Care Of Your Water Softener
KEEPING THE WATER SOFTENER CLEAN
NOZZLE & VENTURI
A clean nozzle and venturi (see Fig. 42) is a must for
the softener to work right. This small unit moves brine
from the salt storage tank 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 clean the nozzle and venturi, complete the following
steps:
1. Remove the softener top cover. Be sure the softener
is in service cycle (no water pressure at nozzle and
venturi).
2. Turn off the cap from the nozzle and venturi housing.
3. Lift out the screen support and screen. Do not lose
the large o-ring seal.
4. Remove 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, flow plugs and screens.
5. Carefully replace all parts in the correct order.
6. Lubricate the o-ring seal with silicone grease or
Vaseline and place in position.
7. Install and tighten the cap, by hand only. Do not
overtighten, which may break the cap or housing.
IRON FROM RESIN BED
Your water softener takes hardness minerals (calcium
and magnesium) out of the water. It can also control
some "clear water" iron. See maximum allowed in the
specifications section in this manual. With clear water
iron, water from a faucet is clear when first put into a
glass. After 15 to 30 minutes, the water begins to cloud
or turn rust colored. A water softener WILL NOT remove
any iron which makes the water cloudy or rusty as it
comes from the faucet (called red water iron). To take
red water iron out of water, or over the maximum of
clear water iron, an iron filter or other equipment is
needed. Your local Sears store has trained people to
help you with iron water problems.
If your water supply has clear water iron, even though
less than the maximum allowed, regular resin bed
cleaning is needed. Your local Sears store has resin
bed cleaner for this. See Parts List in back of manual
for part numbers. Clean the bed at least every six (6)
months. If iron shows up in the soft water before six (6)
months, clean more often. Printed instructions are on
the resin bed cleaner bottle.
