I am trying to repair or replace a Rainsoft water softener system for a friend who's husband is in the Army and deployed to Iraq. She has a AQ48CT/1"/8 softener system with a date code of 9312-1619. It appears that her control valve is no longer functional and goes thru a lot of salt. It also recently developed the bacterial smell (rotten eggs) after she returned from Ft Hood and the house sat unused for almost 3 months. Intend to try shocking it to see if it clears that problem. Since $ IS an issue, are there remanufactured replacement valves that a novice can change? A fellow in my church has a (used) Rainsoft system Model AM18CT/date code 9107-0227/Service flow 6 GPM/Recovery 3050 per 1 lb salt/UL Listed 97hb/LR 52599/Electronic Brain with a Model RF1054Y RN NOT/date code 9107-0848/service flow 4 GPM /Electronic Brain that he will sell for $350. One tank is about 5 ' and the other about 3' and supposedly both works great. Her system only has the single tank and salt "container" and this one has the two plus the salt "container" ????? What does the additional tank do? Any help would be appreciated! Thanks!!!:confused:

We have a Kenmore UltraSoft 400 Water Softener that we recently bought used. My husband installed it and everything seemed fine. A couple of weeks later, our water started smelling bad. Sometimes it has an overwhelming rust smell and sometimes it smells like sulfur. This is typical of Florida well water but softeners usually get rid of most of it. The walls in the shower and the commodes have started turning orange and I can see a difference in our white laundry. The salt level in the tank is still good and there is still water in the salt tank. It recharges like it works just fine. But when I look at the control panel, the Average Daily Gallons is 0 (zero) and the Flow Rate is 0 even with all the faucets in the house turned on full blast and the well pump running. Although (as far as we can tell) it is installed properly, it seems like our water isn't running through it. I know it isn't on Bypass, I've checked it and even tried it on Bypass with no different results. Any suggestions on what I can do before calling in a pro? Thanks in advance.
