Independent guides
Water softener answers, without the sales pitch
Softener Sense is an independent publisher, not a dealer, plumber or water treatment company. We answer the four questions homeowners actually ask: do I need one, which size, how do I set it and what is wrong with it.
What we do
Built around the questions you actually have
Free sizing calculators
Enter your hardness in grains per gallon or ppm (1 gpg is 17.1 ppm), your household size and your water use. The calculator does the grains per day math and gives you a tank size, not a sales lead.
Troubleshooting by brand and valve
Fixes are sorted by brand and control valve, starting with where to find the model label on your unit, then symptom by symptom. Salt not going down, spots coming back, a blinking display: each has a page.
Honest advice, including walk away
We say plainly when you do not need a softener, when a salt-free unit will not fix the problem and when a quote looks oversized for your house. Sometimes the right answer costs nothing.
Costs with a review date
Unit, installation and salt costs are given as current ranges in US dollars, and every price and brand page shows a visible last-reviewed date so you know how fresh the numbers are.
Start where you are
Four situations, four starting points
You bought a house with a softener and no instructions
Start with the model label, usually inside the brine tank lid or on the back of the control valve. That tells you the brand and valve type, which unlocks the right manual, settings and regeneration schedule.
From there, test your hardness, check the salt level and note the settings already programmed. Do not change anything until you know what the last owner set and why.
You have a symptom right now
Salt level has not moved in two months, white spots are back, there is standing water in the brine tank or the display is blinking. Each symptom has a short list of likely causes, ordered from free fixes to parts that cost money.
Most softener problems come down to a handful of parts: the injector, the brine line, the float assembly and the resin. Work through them in order before you call anyone.
A plumber gave you a number and it feels high
Compare the quoted grain capacity against your actual need. A family of four with 10 gpg (171 ppm) hardness uses roughly 3,000 grains per day, which rarely justifies the largest unit on the truck.
We show current price ranges for units and installation so you can tell a fair quote from an oversized one before you sign anything.
You are on a well and seeing orange stains
Iron behaves differently than plain hardness. A softener can handle small amounts of dissolved iron, but higher levels need an iron filter first, or the resin fouls and the softener quits quietly.
Start with a water test that reports hardness, iron and pH. Then size the system for iron, not just grains per gallon.

Sizing is arithmetic, not guesswork
A softener is sized in grains of hardness it can remove before it needs to regenerate, which is the cleaning cycle where salt water flushes the resin and sends the hardness down the drain. Size it too small and it regenerates constantly, wasting salt and water. Size it too big and it sits stale between cycles.
The math is simple. Multiply the people in your house by roughly 75 gallons per person per day, then by your hardness in grains per gallon. That is your daily grain load. Pick a unit that regenerates about once a week on that load.
Our calculator does this for you, with hardness entered in grains per gallon or ppm, and it flags when your hardness or iron level means a standard softener is the wrong tool entirely.
Your first hour
If you just moved in and know nothing
Find the model label
Look inside the brine tank lid or on the control valve body. Write down the brand and model. That one step determines every setting, part and manual that applies to your unit.
Test your hardness
Use an inexpensive test strip kit at the kitchen tap. Note the result in grains per gallon, and in ppm if the kit reports it. Above 7 gpg (120 ppm), a softener usually pays for itself in appliance life and soap.
Check salt and settings
Open the brine tank. Salt should be above the water line, and the display should show a hardness setting that matches your test. If the setting is wildly off, the last owner may have been wasting salt for years.
Watch one full week
Note whether the salt level drops and whether the unit regenerates on schedule. If the salt never moves, the unit is not drawing brine, and our troubleshooting pages take it from there.
Questions we hear every week
Do I actually need a water softener?
Only if your water is hard. Test it first. Below about 3.5 gpg (60 ppm), a softener buys you almost nothing. Between 3.5 and 7 gpg it is a comfort choice. Above 7 gpg (120 ppm), scale starts costing you real money in water heaters, fixtures and soap, and a softener usually makes sense.
What size softener do I need?
Size comes from your daily grain load: people times about 75 gallons each, times your hardness in grains per gallon. A family of four at 10 gpg (171 ppm) needs about 3,000 grains removed per day, which a standard 32,000 grain unit handles on a weekly regeneration. Bigger is not better if it means the unit sits idle.
How much salt should a softener use?
A correctly set residential unit typically uses 6 to 15 pounds of salt per regeneration, so a 40-pound bag lasts most households three to six weeks. If your salt has not moved in two months, the unit is not drawing brine. If you are adding a bag a week, the settings are wrong or the unit is oversized for the program.
Will a salt-free conditioner do the same job?
No. Salt-free systems condition the water so scale sticks less, but they do not remove hardness. If you want soft water, meaning no scale, better soap lather and no spots, only ion exchange with salt does that. For some low-hardness homes, conditioning is enough, and we say so plainly.
My softener display is blinking. Is it broken?
Usually not. A blinking display is often just a regeneration in progress, a low salt reminder or a power loss that reset the clock. Check the manual for your specific control valve, since Fleck, Clack and manufacturer-branded heads all signal differently. Our brand pages start with the label location and go symptom by symptom.
