  Frequently Asked Questions - Softeners

  • How much salt does a softener hold? The salt storage capacity of a brine tank is calculated based on the solid salt above the brine platform with the tank filled with solid salt to with 6 inches of the top plus the salt contained in the saturated brine (2.6 lbs of salt / gallon). See catalog section 610.  A better question might be

  • How much salt is required for the initial charge of a brine tank? Plan on adding about half of the listed salt storage capacity on the initial charge.

  • How often will the brine tank need refilling with salt? Assuming the worst case of a minimum six regenerations in storage after the tank is full of salt and assuming you regenerate each softener each day, plan on refilling the brine tank every six days for a simplex, three days for a twin, two days for a triplex and two days for a quad. One way to avoid bags of salt is to use a brine maker.

  • How do I know if the softener is working? If the water is soft, the system is using salt and the controller display is readable, the softener is probably working.

  • Who do I call if my softener, filter, RO or other water treatment equipment is not working? Contact the Water King representative that sold you the system or the representative in your area. OR Contact Us.

  • How do I get a manual? Manuals are available in the Manuals section of our website, they are on the Water King CD, and they are included with every system we ship. If you cannot find the manual that you need, Contact the Water King representative that sold you the system or the representative in your area. OR Contact Us.

  • How long does the resin last? If you are taking a softener off line and it is more than 5 years old, replace the resin. Water King has resin packs. Don't forget to order internals incase one gets broken during the rebed.

  • Discussion: Resin life varies with use and water quality, particularly the chlorine content. The most used system I am aware of has a Triplex 750 softener that regenerates each vessel three times per day running 24/7. They experience increased head loss and increased hardness bleed at about 3 years. We generally say resin life is 5 years under normal circumstances. An easy way to check the resin is to look at it under a microscope. Cracked beads are readily observed. It is not uncommon for resin to last for more than five years.

  • I have limited flow to backwash and my system will not draw brine. What could be the cause?  

    All softeners have a “Backwash Flow control” located in the drain line.  Smaller systems have this attached to the control valve itself. while larger systems may have a separate fitting plumbed into the drain line. This piece typically will contain one or more rubber “flow buttons”, which regulate the backwash flow rate.

    It is not uncommon for rust, pipe scale, or other foreign matter to become lodged in one or more of these buttons, reducing the flow rate to the drain. This will result not only in incomplete backwashing and rinsing, but in reduced or lack of brine draw.  Always check for full and unrestricted flow to drain during backwash and brine cycles. 

    The photos below show a piece of the TM-II piston lodged in one of the flow control buttons.


  • How do I ensure that the Taskmaster-III piston sensor is positioned correctly? 

    Unlike the older series 180 and 182 brass valves that you may be familiar with, the 150 valve has no micro switches or cam to adjust or get out of adjustment. These valves are controlled by a pair of LED sensors and a notched wheel.  Basically, there is mo adjustment required or available for these valves.  That being said, if you believe that you are having positioning issues, there are several points that you might check:

    1. Make sure that the set screw on the drive link is securely tightened to the shaft. Any play here will affect the piston "timing". This, or worn piston seals,  is the most common source of brining problems.

    2. Although technically not adjustable, there is a very small amount of movement possible in the notched wheel. We have seen cases where over tightening of the screw will cause it to shift just enough to have an effect on the brining position. This is corrected by loosening the screw, then rotate the wheel counter-clockwise until any slack is removed. Then while holding the wheel to prevent it from turning, snug up the retaining screw.  This will only give you maybe one degree or so of change, but this is sometimes all it takes to make a difference.

    3. There is also a very small amount of movement available of the LED mounting plate.

    Again, under normal conditions, no piston/cam adjustment should ever be required on these valves, and no provisions have been made for any.  All valves are completely performance tested before leaving the plant and should need no attention for some time. The above steps should only be required in the rare cases where tolerances have been affected by wear or other conditions.
