She has a softener, but the water still leaves deposits on the shower door, and on glasses after they're washed. And at the same time the water doesn't taste good. (In her previous home she drank water from the tap, after it went through some filter that screwed to the kitchen faucet.)
Somewhere, here?, I got the impression that softening the water more might lessen the deposits, but it would make the taste worse, and vice versa. Yes????
Maybe she could fill her water pitcher with the well water, before it went through the softener. Is there are a chance the water would taste better then? She says there is no spigot to do that with. The house was built with loads of bells and whistles. Shouldn't there be a way to bypass the softener and find out what the water tastes like unsoftened???
If it did taste better, she'd be willing to pay to put in a spigot and go to the basement to fill her water bottle. She might even be willing to run a pipe up to the kitchen counter.
She lives in what was rolling farmland near Finksburg / Westminster Maryland. Only a quarter mile from one of Baltimore's water reservoirs. IIRC, Baltimore barely treats its water -- just a little chlorine and maybe fluoride -- before sending it to homes.
