Water Softener Checklist: if the Softener is Not Working Check These First

if the water softener doesn't seem to be doing anything, check these items:
  • Check the water softener bypass valve: You want first to see that the water softener is not on "bypass" - is household water flowing through the unit? A sketch of an Autotrol bypass valve is shown at left.

    Details about how to use the water softener bypass valve are at BYPASS VALVE.

    This valve is an option and may not be installed on your unit. But there may be standard plumbing valves or globe valves that accomplish the same purpose.
  • Check power to the water softener: If the unit uses electricity to run a timer be sure it's plugged in to a live outlet and has power. Some water conditioners use a low-voltage transformer to power the control - be sure that device is present, plugged in, and working. You can use a simple VOM to check that the transformer is outputting DC at the proper voltage level.

    See USING DMMs VOMs SAFELY
  • Check salt tank: Is there salt in the salt tank?
  • Manually regen cycle: Then try a manual regen cycle - you'll see on most units a lever you can push on the control box to start that process
  • Set the water conditioner controls: Set the right doses and regen cycles for your water hardness and level of water usage
  • Watch the water conditioner timer: it is possible that the timer mechanism itself has failed. You should see the timer wheels or clock wheels turning and, if you try setting a regen cycle at every day (just for starters) you should see and hear the system go through a regeneration cycle automatically the very next night.
  • Feel and test the water supply: if you still can't get a lather when bathing the water may be insufficiently treated, or if the water feels slimy and you have trouble washing soap off, the water may be over-treated. Test the water for hardness so that you know how to set the controls.

How to Get a Water Softener Working & Confirm that It Works Correctly

Before replacing a water softener - a step that may not be necessary, here are some things to try:

  1. Make sure that the water softener is actually "on" and working, that is, that the system has electric power, valves turned on, not left on "bypass"
  2. Make sure the water softener is clean and that no debris is blocking any water passages or tubing.

    See SOFTENER CLEANING & SANITIZING

    Also see DIRT & DEBRIS in BRINE TANK
  3. Make sure that the salt tank is properly filled.

    If the salt tank has stayed "full" for a long time, either no salt is being used (improper operation) or a crust of salt has formed over a virtually empty tank. Poke around into the salt to be sure the salt tank is really there.

    See BRINE TANK BRIDGING or CRUSTING
  4. Run an extra water softener regen cycle - use the water softener control to run the equipment through an extra cleaning/regeneration cycle.
  5. Watch the water softener control or check it frequently for several days to be sure the control is actually working and that it is cleaning and regenerating the water softener salt dose regularly.

    See DIAGNOSE SOFTENER BACKUP / FLOODING.
  6. Test the incoming water for hardness so that you know what level of treatment is required.

    See DETECT HARD WATER and MEASURE WATER HARDNESS
  7. Test the water softener output water for hardness and if you like, also test the output water salt level for excess salt
  8. Check the water softener control adjustments. If the equipment appears to be working, but water is still too hard (or has too much mineral content) you can increase the salt dose or the backwash/regeneration cycle frequency.

    See SOFTENER ADJUSTMENT & CONTROLS
    and
    RECOMMENDED SETTINGS for WATER SOFTENERS
  9. If the water softener is leaving too much salt in the water, reduce the salt dose on your softener's controls. You may see this as a thin salty film left at faucets or in a dishwasher. Mineral scale may also be a thin hard white deposit but is a separate problem not a too-much-salt problem.

    See HEALTH RISKS & WATER SOFTENERS

    and SALT OR WATER INTO SEPTIC
  10. Call for professional help with the water softener. If the equipment is not visibly broken, damaged, leaking, and/or you don't want to mess with it yourself, most water softener companies will be glad to send a service technician to your home to inspect, clean, adjust, and test the equipment.

Try these water softener diagnosis and repair steps before rushing to replace the water softener itself.

Reader Question: Water Softener Not Softening the Water: water test shows 1120 ppm of hardness and other data - how should I remove the hardness?

In my home the water test report showing the following details :

PARTICULARS OUR WATER RECOMMEND LEVEL
PH 7.7 7.5 - 8.5
TDS 1266 PPM
HARDENSS 1120 PPM
ALKANITY 450 PPM
CHLORIDES 764 PPM

Note: Not advisable for cooking & Bathing purpose use for floor cleaning & flushing.

Can I know what is the best way to remove the hardness of water. - Shobia 6/20/12

Reply: water softener capacity must be able to handle level of water hardness

Shobia it does sound as if you'd need water treatment to make that water usable in the home; if you call two local water treatment companies they will be glad to propose systems to meet your needs, and typically don't charge for that advice. Using hardness as an example, it's quite simple to check the level of hardness you need to deal with against the capacity of the water softener system proposed.

I can't say more as I don't understand your data - hardness is usually expressed in milligrams per liter or grains per gallon, not parts per million.

Reader Comment from Cullman 8/26/12:

You need larger size water softener to remove this high hardness. Also TDS (total dissolved solids) level is very high , so for drinking water I suggest using Reverse osmosis system at the kitchen sink. Ph level is good.

Thanks Cullman for the helpful suggestions to Shobia - Ed.

Reader Question: Water softener keeps regenerating & water remains hard

About once a year my softener will have salt in the tank and will run regenerating. But nothing happens and the water remains hard running throughout he house.

Maybe something is clogged? What should I look to do. Thanks so much. - Rob P. 7/24/12

Rob, check for a stuck float switch in the brine tank;

Reader Question: Can I replace the resin media inside of a water softener?

8/31/14 Ron Fix It Man said:

My softener is 13 years old and I have read the resin becomes ineffective in about that life time. Iron out has been used with little benefit. Effectiveness of the softener has declined unless greater amounts of salt per cycle are used. Troubleshooting reveals no improper cycle operation. Is it true the resin has a limited life? Can it be restored, say with a wash of dilute muratic acid? If not, where can it be purchased?

Reply: procedure to replace water softener treatment tank resin media

Ron

Indeed it is possible to replace the resin in a water softener.

Water softener resin can last for 20 years or even longer, but may have a shorter life depending on the chemistry of the water being processed in the water softener. But I would not start down the "replace water softener resin" path before diagnosing the problem with my water softener to be sure I'm making the proper and necessary repair.

If you've done that and are ready to replace the resin in the softner tank, details of just how to replace the resin in the water softner, where to buy resin, and other advice are

White Scale Deposits on Plumbing Fixtures: hard water indicators

Question: White Deposits on Faucets: why does my water keep leaving water marks on my plumbing fixtures? Should I replace my water softener?

White scale on faucets - hard water (C) Daniel FriedmanI currently have a water softener system in my home BUT, there are always water marks on my chrome fixtures and on my windows,mirrors,etc.

What can I do to improve this system or should I just replace it with a different one?

I realize that soft water does not mean non-staining water but I was hoping for better results.

Can you help of advise? - C.T.

Reply: Diagnose, clean, adjust, and test your water softener before buying a new one

We speculate that there are several likely explanations for what you describe:

The water softener is not working adequately or not properly adjusted, does not remove enough minerals, and minerals continue to be deposited on your fixtures

The water softener is not adjusted properly and excess salt is being sent through your system, depositing salt on the fixtures.

The water softener unit is dirty, and needs cleaning and perhaps also adjustment

The water softener simply has stopped working - broken, perhaps leaking, clogged, or with a control that no longer functions.

The water softener regeneration system is not working: no salt in the salt tank, or improper regeneration cycle or salt dose setting, or the regeneration control timer may be stuck.

See DIAGNOSE SOFTENER BACKUP / FLOODING for an example of what can happen.

Watch out: too often a water softener failure or operating problem that could have been corrected by a simple adjustment, cleaning, or repair, is in stead "repaired" by installing new equipment.

Since a new water softener just installed is more likely to be clean and properly adjusted, the old problem may indeed go away, and you may think that replacement was needed, but if simple cleaning and adjustment of the old water softener would have been sufficient, you have faced an unnecessary expense.

Reader Question: corroded drains & faucets - does this mean a water softener problem?

Our drains and faucets are starting to corrode and rust. we have always used a water softener and maintained it. Is this an indication that there is a problem with our softener? - Sharon Osterby 9/16/12

Reply:

Sharon I'm not sure the problem is with your water softener or with the chemistry of your water. If the softener is not working you might see white mineral build-up at faucet strainers and openings; If the water chemistry is aggressive that might be a factor in plumbing corrosion.

Start by testing your softened water to see if it is effectively treated, and if not, clean, adjust, repair the water softener first.

If you suspect a problem with water chemistry (say the softener is working normally and the water at the tap is not hard) then I suggest asking a water treatment company to test your water. Such vendors often will test your water at no charge (they want to sell you equipment) or if you're doubtful, pick up a sterile bottle from your local water test lab and ask their recommendations for what screening tests to perform.
