Thought I'd post this issue we've had since we bought this property close to 5 years ago. The water source is a 402 ft deep well, 6.25" in diameter with the galvanized casing going down 42 feet. We have a few issues... was tested having low PH, 5.8. At the time of testing showed to have iron, 3ppm I think. Problem is it fluctuates. Everything else is OK including hardness which was 3 grains. Since we had a decent Rainsoft softener at the house we sold we bought it here. Thought it'd help with the iron and the little bit of hardness. Did nothing for the iron. We called out the local Rainsoft dealer and they told us about 2 systems we could go with. First was the usual iron filter, PH neutralizing filter, etc.... cheaper of the 2 but would require maintenance here and there along with rebedding. 2nd option was a chemical injection system. Said it has no limits like the filter setup, but of course it cost more and involves getting/refilling the chemicals often. We went with the chemical feed system... Basically the water goes to a 120 gallon retention tank, along the way it is injected with alum for the iron removal, caustic for the PH and bleach to help with disinfecting/iron oxidation. Our water didn't test for any bacteria, but in this state it (bleach) is required with systems like this. After the water is saturated with the chemicals in the 120 gallon tank it goes through a large wholehouse carbon filter (9"x48") then through the softener. Overall the system works great but the iron levels fluctuate, making it hard to keep dialed in. When we gets lots of rain after a dry spell or when we use alot of water daily, which I think draws it down faster than it can recover, etc..... it turns rather cloudy, like diluted orange juice at times. I have done alot of research and found that the typical veins feeding wells don't discharge alot of iron like this at once. We are thinking the main problem is the galvanized casing being corroded is causing this as the static water level rises and falls in the well, stirring it up each time. We contacted a few local well drillers about possibly video inspecting/lining it with PVC. Seems like a great option, but not cheap. Both guys pretty much told me it sounds like the problem and is an easy fix... Any of you have the same issues? It'd be nice to use less chemicals or be able to stop using them altogether. Thanks in advance.
