@Joethewaterguy,
Joe, I suspect it isn't. The house was empty for almost two years, and nothing was done. I tried to do basic cleaning and stuff before we moved in, and also found the timer motor was not functioning on the silver system, so it never regen'ed. I actually have no idea what the filter media is on the silver, but guessed it was greensand. I ordered and installed a new timer back in May, and that got the Silver series working. It was set so that half the buttons were pushed in, so it regens every other night for about45 minutes.
The guy that contracted everything and drilled the well came by and did a raw water retest, said I had almost 6ppm of iron, said there was also a lot of maganese, didn't tell me the hardness, but said it wasn't that bad.
We had a discussion about the well, which isn't that deep, about 200 feet, and some in the neighborhood have better luck with wells about 500 feet, and cased to 200. Drilling a new well has no gurantees, and will cost me about $8,000.
Neighbors have told me they are using more involved systems, some sort of clorine injection, and also air injection.
H2O Man, thanks for the help on the valve, I took it apart, cleaned it using Zep acidic toliet cleaner and some tiny brushes. It was pretty bad looking. The brine injector was pretty plugged. I also found what I think is a resin ball, about the size of a BB, in behind where the brine injector came out. I took it out through the brine port. I didn't take out the big valve pieces from the top, just the brine injector parts after loosening the three screws to raise the large valve piece.
After reassembly, the valve draws brine from the tank, and the water has improved but with one major exception. The first two times the system regen'ed, there was some very yellow and grey water that came through and I had to run the water for awhile until it cleared at the faucets. I don't know if this will continue, only regen'ed twice since I did the reassembly Saturday.
On the Gold AQC75, it appears that the hardness is set on 55. If I recall right, the gallons to regen are 380.
My gut is telling me to replace the front Silver series with something more like the neighbors, one of these injection systems. The simple ones seem to use bleach or air, one of the richer neighbors has one that uses peroxide. I wonder how much he uses. I hate to spend 8k on yet another well with no guarantees.
I would appreciate all suggestion on what to do at this point. Appreciate all the help so far, I am certainly better off than when I started.
