I have moderate sediment and iron in my 145' well here on my property.
I used to be OK with just a pitcher filter but we were in that direct CAT 5 hit on Panama City, (Fl) a few years back and well the plumbing is old and it MOVED.
So I put in a two-by-10" 3/8's input full cart sized system I had here, took the useless line from the icemaker to it and after letting it run clear for a good 20-30 minutes plugged it in. I have activated carbon on the inlet side and a KDF media filter on the exit side.
I may just be being picky but I seem to get a sort of aftertaste from the thing. I put a brand new dedicated faucet in the sprayer hole too with all new lines but the icemaker feed.
The animals don't like the water either.
