Cleaning Iron Out of the Water Softening System
The
Fleet Farm Water Treatment
system is designed to remove minerals like calcium and magnesium from
household water.
Fleet Farm Water Treatment
recommends periodic resin bed cleaning if your iron rating is high.
Clean the bed at least every six months, or more if iron appears in the soft water between cleanings.
Checking for a Salt Bridge
A hard crust or "Salt Bridge" can form in the lower half of the salt storage tank. This can be deceiving because the
tank will appear to have plenty of salt, but underneath, salt has hardened and when the system regenerates, water
cannot quite reach this level to be made into brine (water and salt).
Breaking a Salt Bridge
Take a wooden broom handle 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 probably a salt bridge. Carefully break the bridge with
the broom handle. Do not pound on the walls of the tank.
NOTE: Salt bridges are typically caused by high humidity or using the wrong kind of salt. In humid areas it is best to
fill with less salt, more often. Use only nugget, pellet, block, or coarse solar salt with a purity of 99.5% or higher. DO
NOT granulated, and ice cream-making salts, or salt with iron-removing additives.
Cleaning the Injector and Screen
1) Turn off water supply to conditioner:
a) If the conditioner installation has a “three valve” by-pass system, first open the valve in the bypass line, and then
close the valves at the conditioner inlet and outlet.
b) If the conditioner has an integral by-pass valve, put it in the by-pass position.
c) If there is only a shut-off valve near the conditioner inlet, close it.
2) Relieve water pressure in the conditioner by stepping the control into the backwash position momentarily. Return the
control to the service position.
3) Unplug electrical cord from outlet.
4) Disconnect brine tube and drain line connections at the injector body.
5) Remove the two injector body mounting screws. The injector and brine module can now be removed from the control
valve. Clean and reassemble.
6) To replace brine valve.
a) Pull brine valve from injector body, also remove and discard O-ring at bottom of brine valve hole.
b) Apply silicone lubricant to new
O-
ring and reinstall at bottom of brine valve hole.
c) Apply silicone lubricant to
O-
ring on new valve assembly and press into brine valve hole, shoulder on bushing
should be flush with injector body.
7) To replace injectors and screen.
a) Remove injector cap and screen, discard
O-
ring. Unscrew injector nozzle and throat.
b) Screw in new injector throat and nozzle, be sure they are sealed tightly. Install a new screen.
c) Apply silicone lubricant to new
O-
ring and install around oval extension on injector cap.
8) Apply silicone lubricant to three new
O-
rings and install over three bosses on injector body.
9) Insert screws with washers thru injector cap and injector. Place this assembly thru hole in timer housing and into
mating holes in the valve body.
10) Tighten screws.
11) Reconnect brine tube and drain line.
12) Return by-pass or inlet valving to normal service position. Water pressure should now be applied to the conditioner,
and any by-pass line shut off.
13) Check for leaks at all seal areas. Check drain seal with the control in the backwash position.
14) Plug electrical cord into outlet.
15) Set time of day and cycle the control valve manually to
assure proper function. Make sure control valve is
returned to the service position.
16) Make sure there is enough salt in the brine tank.
17) Start regeneration cycle manually if water is hard.
Hard water enters the unit at the valve inlet -flows around
the lower piston groove - thru the injector throat - thru the
brine valve and flow control to fill the brine tank. Hard
water also flows around the lower piston groove - thru
the passage to the top of tank - down thru the resin and
enters the distributor as conditioned water. The
conditioned water flows up thru the center tube to the
-12- valve outlet.
