How often does a salt based water softener have to regenerate...and for how
long ? We have a rental home that has 2 adults. Based on the size of the
salt tank...I'd say it's a medium to large capacity softener. I've written
the manufacturer a couple times for a manual..but get no response. It's
about 10-12 years old. Does it have to regenerate every night,...and/or for
how long for each regen period ?

Thanks much,
Tim
