According to the Water Quality Association, the hardness scale, measured in gpg of calcium carbonate, can be represented as follows: Less than 1 gpg is considered soft Between 1 and 3.5 gpg is considered slightly hard
The majority of findings are delivered as a number that reports the concentration of calcium carbonate or other equivalents for a given unit of water. The water hardness scale result may be expressed in parts per million (ppm), grains per gallon (gpg), or milligrams per liter (mg/L).
The Culligan HE Municipal Water Softeners are tested and certified by WQA against NSF/ANSI Standard 372, CSA B483.1, and NSF/ANSI Standard 44 for the effective reduction of hardness (calcium and magnesium), and NSF/ANSI Standard 42 for the effective reduction of Chlorine Taste and Odor, as verified and substantiated by test data. The Culligan ...
To find out what size water softener you need, you must identify factors such as water hardness levels and daily water consumption habits, then use this information to choose the proper softener capacity.
The Culligan Medallist Series Water Softeners are tested and validated by WQA and certified by UL against ANSI/NSF Standard 44 for the effective reduction of calcium and magnesium (hardness) along with Barium and Radium 226/228*.
31 Μαΐ 2022 · Your water softener hardness setting should be based on your water supplies water hardness level and its iron concentration, for example a water hardness level of 25 grains per gallon (gpg) and 0.3 parts per million (ppm) of iron would result in a water softener hardness setting of 27.
One grain per gallon (gpg) is equivalent to 17.14 parts per million (ppm). Water hardness can be measured in gpg or ppm, but gpg is the most commonly used measurement. 20,000–80,000: This range signifies the grain capacity of most water softeners available on the market.
