What setting does a softener need on Grafton village water?
A softener has to be told how hard its water is. For homes on the Village of Grafton's system, the Village has already measured: approximately 22 grains per gallon. Here is how that number gets used, and how to check a softener you already own.
Call (262) 829-5961Mon to Fri, 7am to 5pmWhat the hardness setting does
A metered softener counts the gallons that pass through it. The hardness setting tells it how many grains each of those gallons carries, about 22 on Grafton village water, and from the two numbers together it works out when its resin is due to regenerate.
If the setting is lower than the real water, the softener waits too long, and hard water can reach your taps before it regenerates. A setting that matches the water is the whole point of having one.
The starting number for a village connection
The Village's 2025 report gives approximately 22 grains, the same measurement as its 377 parts per million average in a different unit. For a house on the village system, that is where the setting starts.
On installation day the plumber's reading at your tap checks that figure against your own water before anything is connected, and the number of people in the house goes into the sizing next to it.
Wisconsin's code and the meter
Under SPS 382.40(8)(j), Wisconsin's plumbing code expects a softener to be demand-initiated: it decides when to regenerate by a meter or a sensor rather than by a clock. The softeners supplied for Grafton homes are that kind, and the hardness setting is the figure the meter works from.
The installation page covers the code itself. What matters here is that a demand-initiated softener can only act on the number it is given, so the number has to be right.
Checking the softener you already have
On many control valves the hardness setting appears in the settings menu, in grains, and the owner's manual shows where to find it. On village water, compare it with 22.
A setting well below that means the unit was set up for different water, or never changed from its starting value. On a private well, compare the setting with your lab figure instead, after dividing the lab's number by 17.1 to get grains.
The tap has the last word
A setting is only a number typed into a valve. The proof is at the faucet: once a new softener is in, the plumber retests your tap, as many times as it takes, until it reads zero hardness, and that reading is the one to trust over anything on a display. On village water, that means watching about 22 grains come down to nothing.
Common questions
Should I set it higher than 22, just in case?
There is no need to guess high. The setting describes the incoming water so the softener regenerates in time, and what it should match is the real hardness: about 22 grains on village water, confirmed by the plumber's reading on installation day.
Can I change the setting on my own softener?
On a softener you own, the owner's manual shows how. Match it to the water: about 22 grains on village water, or your lab figure, converted to grains, on a well.
