I live on a well too but it’s really clean stuff. Very little iron. The 20 MTB added to wash and dishes really makes for squeaky clean stuff.
We filter the fool out of our water with under-house filters, then our drinking water I filter in a large Brita container. It tastes fine to us, but still has the iron and sulfur a bit; the family likes to hassle us about it but we’re doing the best we can. Also grateful for the free water! - Thanks for the info on the 20 MTB. We live in a heavy limestone area in addition.
