I had the water tested a while back in a rental that is not far from my house. More iron than my residence, I believe it was about 4 or 5 ppm. about 9 or 10 days ago, I threw in a Kenmore softener to replace an aging one at the rental house. At the same time, I replaced the pleated cartridge filter. This is on a well (that I have not yet had tested, but plan to) with a Gould J05 0.5 hp pump and tank, with 1/2" copper lines. When I installed the new softener, I used the old bypass due to the fittings, but replaced the pushrod and seals.
There was so much red crud in the lines! I'd estimate the ID due to rust/iron (I assume; it was very orange) was about the diameter of a #2 pencil or smaller.
At any rate, the renter complained tonight of LOW pressure, and after looking things over, decided the filter was clogged. Removed it, and voila! flow was restored. Threw in a new cartridge, and we were up and running again.
Pending some good water testing, what is a viable solution to remove that much rust/iron from the water? If it kills a cartridge in 10 days, that seems pretty bad to me, whose cartridge can last 6 months.
