Before replacing a water softener - a step that may not be necessary, here are some things to try:
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 :
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;
and see BRINE TANK FLOAT LEVEL ADJUSTMENT in our water softener diagnosis & maintenance articles.
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
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 at SOFTENER RESIN REPLACEMENT
Question: White Deposits on Faucets: why does my water keep leaving water marks on my plumbing fixtures? Should I replace my water softener?
(Feb 19, 2014) Bruce said:
My softener stopped softening the water 2 months ago. The unit is about 18 years old. I replaced the resin, cleaned the valve head, poured 3 gallons not water into the brine tank with iron out and manually regenerated many times. The water gets soft for a few days but then isn't. It's using salt normally, the valve timer is working but still won't keep the water soft. The only thing I haven't done is disassemble and clean the brine tank. Any suggestions are greatly appreciated.
Check the float assembly to assure it's not stuck and check the salt dose setting against the measured hardness of the incoming water supply;
Thanks Dan, the float assembly looked fine. I soaked the basket in Ironout just in case and blew it out, seems clear. The salt setting was at 3 lbs which seems rather low so I bumped it up to 13 lbs. The last water test was pH 5.8 / Iron 3.0ppm / Hardness 20 grains per gallon. What setting do you recommend for that iron level? Again, your help is really appreciated.
The separate article SOFTENER ADJUSTMENT & CONTROLS discusses salt dose and regen cycle settings - which you can look at but you'll want to set your particular softner salt dose and regen cycle frequency per the instructions for your particular brand and model to get it just right.
I don't know about softener setting for iron level - which is a secondary feature to softener settings for hardness; I'd be glad to do some research but let's start with the instructions for your unit. What is the brand and model? (And you have the instructions for it?}

How much water should be in the brine tank after a full regeneration? I'm starting to wonder if the air check ball is stuck or for some reason, the correct amount of brine water is not being created.
Indeed there are usually a few inches in the bottom of the brine tank, but in normal conditions you won't see it: the brine solution will be covered by salt.
- check that the float assembly travels freely and is not stuck - most brine tanks control water entry and exit quantity by a float operated switch.
- poke at the salt in the tank; salt can form a crust that makes it look as if there's plenty of salt in the tank while actually there may be nothing but hollow space below the crust.
There is about 3-4" of water but the float sits about 5-6" above the water line while in service mode. Does the water go up that high during regeneration? Doesn't seem like it does at all. Further to that, I opened the air check where the brine tank hose attached expecting to find a ball but there wasn't one. I understand that the all floats when water is in there and close up the line when the brine water runs out. But there was no ball. Also, my air check looks different than the ones I see pictured, it's flatter than taller. I can send a pic if that's possible. Thanks again, you are very helpful, I appreciate it,
Bruce, I'm not sure, not even knowing what softener you have, but generally the float controls the quantity of water that enters the brine tank - as you probably see, water enters, causes the float to rise until it shuts off the incoming water; time is given to dissolve salt; then salty water is pumped back out of the brine tank and through the softener to do the regen.
If you want to experiment, with no salt in the tank, so you can see what's going on, use the softener controls to request an extra or manual regen cycle. Watch the brine tank. You should see water enter, the float rise, the float stops rising and presses against a mechanical switch that stops water entry. (The float level is adjustable on many softeners and should be set per the manual).
As the cycle continues you should see the salty water pumped back out of the unit and the water level drop.
Even before that observation it should be possible to GENTLY lift the float rod and let it drop back into position. The float should move freely up and down. Sometimes floats get stuck as salt cakes or falls into the tube protecting the float assembly.

Thanks, I understand exactly what you wrote. The valve is an Autotrol 255/440 from 1996. Right now, I've the water soft but not sure how long it will last. It's soft because 2 days ago I add 3 gal hot water to the brine tank and did a manual regen. I'm wondering if enough water is getting into the brine tank. Is the float valve itself subject to failure commonly? The float moved the valve freely up and down but that doesn't mean the valve is opening fully, right? Maybe I should watch a full cycle to see if the water rises during the brine creation cycle. That air check w/o a ball also is bothering me since everything I read on the 255 says there should be a plastic ball in there. Also, I read that air leaks could impact brine flow.
Although I'm not the most expert on water softeners I've messed with them a bit and inspected quite a few. It is common for the brine tank float to get stuck or fail to operate properly. Some folks go on for years with the system not working, never realizing a thing until their water pipes clog with minerals that the softener was not removing because it was not doing a thing.
I haven't come across the air leak problem but that makes some sense, though I'd like to hear more specifics about where the air leaks occur; I suspect that an air leak in the brine line between brine tank and softener might let air rather than brine pass back to the softener, but I'd think during the brine tank fill cycle you'd see water leaks at the same place. The manual for your water softener says an air leak in the brine line can cause a brine tank overflow.
I'd suggest removing all the salt (you've done that) then starting a manual regen cycle and then stand there and with the lid off the brine tank watch what it does. You should see water enter, the float rise, the float stop the water entry, then the water flow should reverse and flow back through the softener.
(If you'd photograph the whole sequence and email me those that'd be a useful addition to our diagnostic routines online.)
Take a look at the diagnostics page in the manual - I'll quote some key passages:
Continuing with Autotrol w55/440 Water softener diagnostics, here are things to watch for during the regen cycle:
Control will not draw brine: possible causes-
- low water pressure
- restricted drain line
- injector plugged or defective
- Valve 2 disc and/or 3 not closed (see parts diagram)
- Air check valve prematurely closed (there's that air check valve again)
Also interesting is a system that actually takes or uses less salt than the setting on the salt dose dial (I suspect this is a good candidate for your complaint as you say the softener gives soft water after a regen cycle but just for 2 days):
The Dx says look for foreign matter inside the controller - debris causes incorrect flow rates.
You should see this in the quantity of water pumped in and out of the brine tank (it'd be reduced)
Finally, some general Dx for "Run out of Soft Water Between Regen Cycles"
- improper regen (which we've been discussing)
- incorrect salt dose setting
- incorrect hardness or capacity setting
- water hardness has increased (in the incoming water supply)
- Restricted meter turbine rotation due to foreign matter in the meter (see parts diagram)
Given the age of your water softener I'd be alert for the debris-related diagnostics in the company's list.
If you don't have the manual on hand contact me by email and I can send you a copy.
That list is very helpful. I decided to shock the well again today (2nd time in a month) because I still believe it's at the heart of my problems. I'm clogging up a whole house filter once every 7-10 days now. Used to be every 2 months. It's never been a good well and I'm thinking it got worse and the softener simply can't deal with the high iron content, I'm flushing the chlorine out as I type, the hose has been running for well over 1 hour and the water is still very brown.
Hopefully it starts running clear soon. If I can't improve that part and go at least a couple months before a filter change, I think a new well or at least well company inspection is next.
If the water filter clogs in just a few days I'm doubtful that shocking the well is going to do much for it - you'll need to
- find and (ick) fix a leaky cracked damaged well casing or well piping
- install a larger capacity water filter
Reader Jim added:
Look for an air leak at the check valve or brine tank line; possibly an air leak at the backwash control,
Yeah Dan, I think you're on the right track there unfortunately but I'll give it a couple days.
Thanks , I'll look for the leak, still not sure why there is no ball in the air check. Thought that was required for it to work.

We have a tank in our basement that we were told was a salt system. I am confused because it has no brine tank. It is tall and thin with a control box on top. We have lived here 6 months. Finite was the first time I hand heard it "regenerate". It was running for about 20 minutes. My husband turned it off and bypassed it. We don't have a clue about it. Do they all have brine tanks or do some have just a pressure tank??
Your system may not have a separate water brine tank if the unit is an exchange type system:
Some water conditioners use an "exchange tank" design: the resin is pre-charged with salt or other chemicals and is inside a tank taht is exchanged periodically, typically monthly by a water treatment service company.

resin tank full of water and motor runs all time
Anon: I think you mean the salt or brine tank is full of water - the resin is inside the water softener - you can't normally see it.
It sounds as if your water softner control is stuck; try unplugging the unit; if it can't be reset manually the control may need repair or replacement.

I have a rainsoft whole house water system that is showing signs of foamy water. Please let me know what problem can cause the system to make the water foamy?
I'm not sure Lloyd; maybe mis-adjustment, over-softening; have you tried cleaning the brine tank and checking the water softener settings against the actual measured hardness of incoming water?
(Mar 10, 2014) Dan said:
I just had the o rings on my water softener replaced due to leaking, and the system cycles properly. However, after the last 2 cycles, the first water of the morning is distinctly briny, which goes away after using water, say doing a few loads of laundry. This has never happened in 15 years of service. Any suggestions? Thanks.
Check the salt dose - it may be set too high.
YOu can also check the actual water hardness to be sure you've properly set the water softener re-gen frequency and salt dose.

Recently I've been experiencing very foamy and salty tasting water from the cold water faucets in the mornings. I have to run the faucets for several minutes to clear. I have RainSoft about 30 years old. Never maintained except to replace salt.
John, perhaps you need to empty and clean the brine tank, then check that the tank float is moving freely, then run the softener through an extra regen cycle.

my water softener won't stop beeping. And the screen reads " SENDING HELP "
Well that's one I've not heard before. "Sending help"? You didn't mention the brand and model - which would let us (or you) check the owners' manual.
For example Culligan Gold water softeners include a beeper that can be turned on and off and indicates button activity as well as an "alarm" mode.
Your unit needs repair or service.
YOu might try "tapping" on the control motor to see if you can get it going again for a time but I'm not optimistic that even that free-up would be a lasting repair. The motor is accessible by removing the front plastic cover on some water conditioners.
On Rain Soft water softeners you may be able to re-set the alarm. If you have that brand or most others you can obtain a manual from the company's website, and we also have some on file.

My water softener makes noise like water hammering when it regenerates very loud thru out the house

My Crown twin tank water softener is running much longer on its regeneration cycle, 2-3 hours instead of the usual 10-15 minutes.
What is the likely problem & is it something I can fix myself ?
Stuart start by checking the control settings. Then try a manual regen cycle and watch what happens. Is the clock reading ticking or moving? I suspect a debris clogged control, check valve, or possibly a salt-stuck brine float.

This sounds as if the water softener is sending debris from the brine tank OR actual resin from the softener out with the house water supply. You could try emptying and sanitizing the brine tank (articles here describe how to do that). But I suspect it's a resin problem - which means it's time to call your local water conditioner company to take a look at the equipment. I'll do some further checking and comment further as well.
