What You Should Do

1

A water softener is recommended. At 139 ppm, scale buildup will affect your water heater, dishwasher, and plumbing over time.

2

Test your water with strips to confirm. Our estimate is based on USGS county data — a $5–15 test strip kit from a hardware store will verify your exact tap water hardness.
