How hard is the water in Wilkes County, NC?
0.8 grains per gallon
You do not need a softener here.
The median hardness measured in Wilkes County, NC is 14 mg/L as calcium carbonate, which is 0.8 gpg. That is soft on the USGS scale. It comes from 405 samples at 15 sites between 1990 and 2025, drawn from every sampling site in the county, wells and surface water together.
How much it varies here
Half the sites came in between 0.7 and 1.1 gpg. The whole middle of that range gives the same answer, so a test of your own tap is unlikely to change it. Confidence in the county figure: high (how it is measured).
What to do next
You can skip the softener. At 0.8 gpg the most a softener would fix is the odd water spot. If a salesperson in Wilkes County says otherwise, ask to see their reading in grains per gallon and compare it with this one.
