There's a hardware store in this neighborhood of old homes with mostly old
faucets that specializes in repair parts ("ya don't wanna tear out those
walls, do ya?") for American Standard, etc. They say that ceramic valves are
inferior to the old kind in areas where there is a high mineral content to the
water, because it abrades the ceramic. Just wondering if this is true, and if
the old style valves are available anywhere in new faucets.
