Quick Answer
Ironclad Plumbing explains the signs your water softener needs attention because half the time the fix is free (check the salt, break a salt bridge) and the other half depends on whether the unit is worth repairing or needs replacing.
| Sign | What’s Probably Happening | Fix |
|---|---|---|
| White buildup returning on fixtures | Softener isn’t removing hardness. Could be salt bridging, resin exhaustion, or control head failure. | Check salt level first (free). Then call for diagnosis. |
| Salt level isn’t going down | The softener isn’t regenerating. Control head, timer, or motor may have failed. | Repair: $150-$400. If the unit is 10+ years old with a failed control head, replacement may be smarter. |
| Water feels hard (soap doesn’t lather well, dry skin) | Same as buildup — softener isn’t treating. | Diagnosis first. Could be simple (salt bridge, settings) or terminal (dead resin). |
| Softener is running constantly or regenerating every day | Control head malfunction or incorrect settings. | Repair: $150-$300 for a settings fix or valve component. |
| Unit is 10-15+ years old and having multiple issues | Resin bed is exhausted, control head components are wearing out, it’s becoming a maintenance burden. | Replace. A new softener ($2,500 installed) will outperform a dying unit even after expensive repairs. |
Before you call anyone: Check the salt level in the brine tank. If it’s empty or below 1/3, add salt and wait 2-3 regeneration cycles (2-3 days). This solves the problem about 30% of the time and costs $5-$10 in salt.
If salt level is fine but water is still hard: Look into the brine tank with a flashlight. Push down on the salt surface. If there’s a hard crust with an air gap underneath (called a “salt bridge”), the salt isn’t dissolving into the water. Break the bridge with a broom handle. This is another free fix that solves the problem maybe 20% of the time.
If neither of those works: The issue is mechanical (control head, motor, valve) or the resin bed is exhausted. Time for a professional diagnosis.
Repair vs replace decision:
| Unit Age | Issue | Recommendation |
|---|---|---|
| Under 5 years | Any single component failure | Repair. Unit is young. |
| 5-10 years | Salt bridge or settings | Fix it yourself or $150 service call. |
| 5-10 years | Control head or motor failure | Repair ($200-$400). Still has resin life left. |
| 10-15 years | Resin exhaustion (water is hard even after regeneration, settings are correct) | Replace. Resin replacement alone costs $300-$600 and the control head is also aging. New unit ($2,500) comes with fresh everything and a warranty. |
| 10-15 years | Multiple component failures | Replace. Compounding repairs on an aging unit is throwing good money after bad. |
| 15+ years | Anything | Replace. The unit has exceeded its useful life. |
Resin lifespan: Softener resin typically lasts 10-15 years with Austin’s hard water. After that, it loses its ability to exchange ions effectively and the softener stops softening regardless of salt level, settings, or control head condition. This is the most common reason for a working-age softener to stop performing.
One thing to check before replacing: Is the softener sized correctly for your household? A softener that was sized for a 2-person household may be overwhelmed by a 5-person household. The unit isn’t failing — it’s undersized. A plumber can calculate your daily softening demand and recommend the correct capacity.
