Do yourself a favor and buy a water hardness test strip from your local hardware store. It’s cheaper than a fancy coffee and takes ten seconds. Dip it, match the color, and suddenly you know if your water is “hard” (above 7 GPG) or “nuclear-hard” (above 15 GPG). If your test strip turns dark purple, you might have medieval castle plumbing.

Once you know the number, set your softener to about 5 to 10 GPG less than your raw water. For example, if your water comes in at 18 GPG, aim for an output of 8 or 9 GPG. Don’t aim for zero—leave some minerals in, like leaving a few crumbs on a plate so it doesn’t feel lonely.
The Two-Week Rule
After you set the level, give it two weeks. Your skin will adjust, your pipes will adjust, and your coffee machine will stop looking like a fossil exhibit. If your hair feels like wet hay, turn the hardness up a notch. If your soap still isn’t lathering, turn it down. It’s a dance, and you’re the awkward partner stepping on toes.
And if you have a water filtration system too? Don’t panic. Just make sure the softener comes first. You don’t want your filter fighting the minerals—that’s like trying to dry dishes with a wet towel.
