Frequently asked
How do I find out how hard my water is?
Enter your ZIP code above. We match it to your county and show you the public hardness figure for that county, in grains per gallon.
What size water softener do I need?
It comes from two things: how hard your water is and how many people live in your home. Enter both above and you get a capacity range to shop for.
How accurate is this?
It is a county level estimate from public data, so it is a starting point, not a measurement of your tap. A test kit or a lab report gives you your own number.
Does this work for well water?
The hardness figure covers your county's water in general. A well is its own thing, so get a lab test of your well before you buy a system.
Do I have to give you my email?
No. The hardness answer and the size range are on the screen for free. The email is only if you want the report written down.
