Water tastes salty after the softener regenerates

Softened water should not taste salty. A salty taste means brine was not fully drawn and rinsed out of the resin: clogged injector or brine line, restricted drain line or drain flow control, low supply pressure during regeneration, or a regeneration interrupted by a power or pressure loss.

Softener regenerates at the wrong time (often after a power outage)

Most timer and metered controls schedule regeneration by the clock, typically in the middle of the night. After an outage the clock can be wrong or reset, so regenerations happen when people are using water. The softener still softens, but the clock and settings need checking.

Low water pressure after the softener

Pressure loss across a softener usually comes from a clogged pre-filter, fouled or broken-down resin, resin escaping into lines, or a valve stuck partly in a regeneration position. Bypassing the unit isolates it quickly.
