We have an Ultimate II water softener that is aprox 12 yrs old. I've been told it's on it's last legs but I don't know much about them. I have a few questions. We noticed our water bill has skyrocketed from 150 gallons a day to 300 gallons a day in consumption (9000gallons a month!). We are a 3 person household. Thinking there was a leak we shutoff the water valve to the house and the meter stops (it's not an outside leak then?)...so checked each toilet (put food coloring in with no color bleeding down). Our water comes in and up (not down via slab) and thru attic therefore I'm thinking 5000+ excessive gallons in a month we'd see it in ceiling, right? So, we decided to shutoff our water softener (which BTW regenerates every single night-why I do not know but guy set it up that way) and now we are using 150 gallons each day instead. So, my thought is it's the water softener regenerating huge amounts of water. I just need some insight as I'm not familiar with water softeners at all. We had it serviced about a year ago and at that time we were told it was not going to last much longer (but maybe he just told us that-I don't know).
Anybody have any ideas on what is causing this massive loss of water via our water softener? I can't find anything when I google this either. Thanks a bunch!
