Our install · a real job, not stock
You just had a softener installed, but the water still feels hard, or your test says it is. Frustrating — but it’s almost always one of a handful of quick things, and most you can check yourself in a few minutes.
1. You tested the wrong tap (or the hot water)
Test from a cold tap and let it run 15–20 seconds first. Hot water can still read hard for a while (see #7), and outdoor spigots are often plumbed before the softener, so they’re not treated at all.
2. The system is in bypass
If the bypass valve was left in the bypass position, water is flowing around the softener untreated. Make sure it’s set to normal/service.
3. It’s out of salt — or has a “salt bridge”
No salt means no softening. And sometimes salt forms a hard crust with an empty gap underneath, so the tank looks full but isn’t feeding the system. Gently break up any crust with a broom handle and top off the salt.
4. The hardness setting is too low
If the softener is programd for softer water than you actually have, it runs out of capacity early and hard water slips through. On well water especially, the setting also needs to account for iron. This is a common setup miss.
5. It never regenerated
Softeners clean themselves on a cycle (regeneration). If the clock is set to the wrong time of day, it may be cleaning at the wrong time or skipping — and untreated hard water gets through. Here’s how to check the clock.
6. The resin is fouled (common on well water)
Iron in well water can coat the softening resin over time and choke its capacity, so the system “works” but delivers hard water. A resin cleaner often restores it — this one usually needs a pro to confirm.
7. Your water heater hasn’t turned over yet
Right after install, your cold water is soft immediately, but your water heater still holds about 40 gallons of your old hard water. The hot side feels soft once that tank naturally turns over. Give it a little time.
Test strips say hard, but the softener tests zero?
We had this exact call this week. The homeowner’s test strips said the water was hard. We tested it: 10 grains coming in, 0 grains after the softener. The softener was doing its job. When strips and a real test disagree, it’s usually one of these:
- The strip reads in ppm, not grains. Many strips report ppm (mg/L) instead of grains per gallon, and the color chart is easy to misread. One grain is 17.1 ppm, so 10 grains is about 171 ppm.
- The strips are old or got damp. Check the date on the package and read the color at the time it says.
- The tap isn’t on the softener. Outdoor spigots, and in some homes the kitchen cold line or the fridge line, are plumbed before the softener. A bathroom sink is usually a better place to test.
Not sure? Text us a photo of the strip and where you tested it: 941-266-8991.
It doesn’t feel as soft as when it was new
Also common, and usually not a problem. Right after install, the change from hard water is obvious: soap lathers more and rinses off differently. After a few weeks, that’s simply how your water feels. And if you’re still using as much soap and shampoo as you did on hard water, cutting back changes the feel too.
The only way to know for sure is to test the water going into the softener and coming out of it. A working softener takes it to about 0 grains.
Quick answers
Why do my test strips show hard water after a softener?
The tap you tested may not run through the softener, the strip may read in ppm rather than grains, or the strips may be old or damp. A test of the water going in and coming out of the softener settles it.
Why does my soft water not feel slippery anymore?
Usually because you have gotten used to it, or you are still using as much soap as you did on hard water. It does not by itself mean the softener stopped working.
How do I know my softener is working?
Compare the hardness going into the softener with the water coming out. A working softener takes it to about 0 grains per gallon.
Checked all of these and it still tests hard? That’s a real one — and exactly what we’re here for.
