I'd be grateful for H2O Man's thoughts on this!
When I bought my home this fall, it came with a RainSoft "Silver Series" acid neutralizer that was installed in 2008. I have just discovered that it was incorrectly installed, and does not condition any of the downstairs cold water -- it just feeds the upstairs cold water, and hot water heater. I live alone and use only the downstairs plumbing, so all the cold water I use comes directly from the well.
That's a problem because lately I've encountered intermittent cloudy yellow water at the "cold" faucet in all downstairs fixtures. This appears just after the neutralizer back washes 120 gallons every other evening. (NOTE: the water's NOT cloudy wherever it's passed through the neutralizer!) The water gradually clears up over the next day. Yesterday, a plumber whom I brought in to check this problem, suggested that since my well is shallow (he actually ran it dry when flushing the pressure tank), the enormous water demand for the RainSoft back flush may be stirring up silt and causing the discoloration.
So here is my question: can I cut back on the interval of the RainSoft back washes? My home has only one inhabitant (me) who uses only the downstairs bathroom, so the neutralizer doesn't have to process the amount of water it was designed to. (Previously there were 6 people inhabiting both floors.) Throttling it back could help the 'dirty water' condition caused (maybe) by the neutralizer's excessive back wash demands. Can I make this adjustment myself, or should I call the RainSoft folks in? (If myself, then how does one gauge the "correct" interval between back washes, for my particular needs?)
Here are various facts: The neutralizer tank is 12" x 54" and its electro-mechanical control head ("Silver Series") bears the numbers RFC-25K. The controls are similar to those shown in this on-line manual: http://www.rainsoftofnc.com/manuals/AMC75T.pdf
. (Can you refer me to an on-line manual for my unit, or is this the correct one?)
Here are recent water test results (taken at the cold water kitchen tap, which is fed directly from the well without going through the neutralizer): PH 6.00 SU; Manganese .05 mg/L; Iron, .462 mg/L; Hardness 10,0 mg/L. (Could the excess of iron be causing my cloudy yellow water? That's what the RainSoft people suggested, and offered to sell me a water softener for $3100.)
I'd appreciate any thoughts you might have on how to slow down the neutralizer's demands a bit, if you think its furious activity might cause my cloudy water. Of course, eventually I need to re-route the water lines so that the neutralizer processes ALL the house water. But since my crawl space has virtually no access, this will be an expensive proposition. And of course ultimately I need a new and deeper well. But, I'd like to do the inexpensive things first. Many thanks for your unbiased opinions -- everyone else seems to want to sell me more water systems!
