What does salt bridge in a softener mean in practice?
The tank looks full from above, but proper brine is not produced and resin capacity is not restored during regeneration.
When does it matter?
Humidity, unsuitable salt, constant overfilling and lack of inspection encourage the problem.
Which solutions are related to it?
Isolate the unit, break the bridge without damaging the brine well, remove debris and refill clean salt in batches.
