Cleaning Iron Out of the Water Softening System
The WATER DOCTORSsystem is designed to remove minerals like calcium and magnesium from household
water. WATER DOCTORSrecommends 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 or coarse solar salt with a purity of 99.5% or higher.
DO NOT use rock, block, 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, 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) Remove the two injector cap mounting screws.
5) To replace injector and screen.
a) Pull the screen and injector throat/nozzle assembly out of the valve body.
b) Insert a new injector throat/nozzle assembly, be sure they are sealed tightly. Install a new screen.
c) Apply silicone lubricant to new injector cap seal.
6) Replace injector cap with two mounting screws.
7) Tighten
screws.
8) 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.
9) Check for leaks at all seal areas. Check drain seal with the control in the backwash position.
10) Plug electrical cord into outlet.
11) Set time of day and cycle the control valve manually to assure proper function. Make sure control valve is
returned to the service position.
12) Make sure there is enough salt in the brine tank.
13) Start regeneration cycle manually if water is hard.
