How a Softener Problem Gets Diagnosed
Almost every softener complaint reduces to one question: is it regenerating properly? Most units that appear dead are simply not completing a cycle, and the cause is usually mechanical and inexpensive rather than terminal.
1. Confirm the Symptom
Hard water returning, salt not being used, water in the brine tank, continuous running, or leaks are different faults. Testing water hardness at a tap tells the plumber immediately whether the unit is softening at all.
2. Check the Salt and Brine Tank
A salt bridge, where a hard crust forms above an empty cavity, is the single most common cause of a softener quietly stopping. It looks like a full tank and delivers no brine at all.
3. Test the Control Valve
Manually cycling the valve reveals whether it is advancing through the stages properly. Worn pistons and seals, a failed motor, or a stuck injector each show up at a specific point in the cycle.
4. Assess the Resin
Resin lasts many years but eventually degrades, and chlorine or iron shortens that. If resin is the problem, a rebed is generally cheaper than a new system on a unit with a sound valve.
If your unit is genuinely at end of life, see water softener installation. If your concern is taste and odor rather than hardness, see water filtration. Pricing is on our pricing page.
