Decision
Repair or replace a water softener?
Replace at40–50%of the cost of a new system
A common rule of thumb: replace when the repair reaches 40 to 50 percent of the cost of a new system.
Lean toward replacing if the unit is old and needs both resin and a valve, or if parts are no longer made. Lean toward repairing if it is a single, inexpensive part on a newer unit.
