How Hard Is Henderson Water?

ANSWER FIRST

Use regional hardness as a starting point

Henderson’s report webpage lists typical hardness at 304 ppm / 18 gpg; SNWA separately lists regional guidance of 280 ppm / 16 gpg. This is useful context for scale and mineral spotting, rather than a claim that every Henderson property has precisely the same reading. The City report and property sampling serve different purposes.

For a softener proposal, request a measured inlet hardness in grains per gallon and the operating settings based on that reading. Existing treatment, sampling location and a bypass valve can change what a test shows. A test after a softener should be labeled separately from the untreated inlet sample.

Three checks before the next step

1. 01

   Measure untreated inlet hardness

2. 02

   Record units and sampling location

3. 03

   Verify treated hardness after startup

Keep inlet, treated and drinking-tap tests separate

The regional 280 ppm/16 gpg figure provides context, while property measurements support equipment settings. Record where the sample was taken, its units and whether existing treatment was running or bypassed. An untreated inlet and a kitchen RO faucet deliver different water.

Capacity and household flow are different inputs

Hardness helps determine exchange demand and regeneration settings. Simultaneous showers, laundry and other uses shape peak flow. Ask for capacity, service-flow and pressure-drop assumptions; tank height alone is not a sizing method.

Keep commissioning records

Retain the inlet result, control settings and startup notes. Request a treated hardness check and instructions for bypass position, low salt and abnormal cycling. Those records help investigate returning symptoms. Existing deposits may still need cleaning after incoming hardness is addressed.
