Our hard water results in our toilet tank fill/flush valves calcifying up and making the toilet(s) run. Happens every few months. Usually I just replace 'em, a cheap Fluidmaster is under $10. This time however I’ve got this fancy valve that’s supposed to save water (flip handle up for #1, down for #2). I’d love to keep it for a while. Anything I can do to lengthen its service life, short of installing a house-wide water softener?
