Why Hard Water Comes Back
When water turns hard again, the problem is rarely as simple as low salt. A&A Plumbing repairs all major makes of water softeners across San Diego, tracing the real cause and fixing it with upfront, written pricing.
San Diego's water runs hard, about 16 to 18 grains per gallon, and carries chlorine and traces of iron that wear a resin bed out faster than most owners expect.
Before we arrive, three quick checks help: confirm the bypass valve is in the service position, test hardness at a tap, and check the brine tank for a salt bridge or high water.
Water Softener Repair Services
We repair salt bridges, valves, injectors, resin beds, and bypass problems for every major brand.
Salt Bridge Removal
A hard crust above the waterline stops salt from dissolving. We break the bridge, clear the tank, and reset the brine level.
Water softeners →Control Valve & Timer Repair
A stuck valve or dead timer means no regeneration. We repair or replace the valve, piston, and timer so cycles run on schedule.
Water softeners →Injector/Venturi Cleaning
A clogged injector leaves the unit cycling without drawing brine. We clean the screen and venturi so it pulls brine again.
Installation →Resin Bed Replacement
Exhausted or iron-fouled resin cannot soften water. We swap the resin bed and restore full softening capacity.
Replacement →Bypass Valve Repair
A bypass left open or leaking sends hard water past the unit. We service the valve and return it to the service position.
Water filtration →Full System Diagnostics
We test hardness, pressure, and each cycle to pinpoint the fault before recommending any repair.

| Unit regenerates constantly or never cycles | Failed control valve or timer | Repair or replace valve, piston, and timer |
| Resin beads at faucets and low pressure | Cracked distributor tube or worn resin | Replace distributor tube or resin bed |
| Salty taste or hard water right after service | Bypass valve open, water skips the unit | Set bypass to service, retest hardness |

Water Softener Repair Questions

How much does water softener repair cost in San Diego?
In 2026, control valve or timer repair runs $150 to $400, injector and venturi cleaning is usually under $150, a distributor tube replacement is $150 to $350, and a full resin bed replacement is $250 to $400 in parts plus $150 to $300 in labor.
Why is my water hard again if the softener is running?
It is almost never just low salt. The usual causes are a salt bridge, exhausted resin, a clogged injector, a failed valve or timer, a bypass left open, or a cracked distributor tube.
Should I repair or replace my water softener?
If the unit is under about ten years old and the resin is serviceable, repair usually makes sense at $150 to $400 versus $3,200 to $4,500 for a new install. Past twelve to fifteen years with exhausted resin and a mechanical failure, replacing is the better value.
How do I know if my resin bed is bad?
Signs include hard water returning, resin beads at faucets, low pressure, and a unit that no longer softens after regeneration. Resin past ten to fifteen years that is iron or chlorine fouled usually needs replacing.
Can you repair every brand of water softener?
We service the major makes of water softeners and conditioners. Note your model and serial number and any error code before we arrive, and we will confirm parts availability on the call.
