If your water is supplied to you by a city or municipality, we recommend contacting them directly first
for information about your water hardness. Most providers provide water hardness information on their
website or will provide if contacted
- To have a free test kit sent to you please contact us and select request a test kit. Or select submit a sample to send us a sample for full analysis.
- Ideal regeneration frequency is 4 to 6 days at 75% of total capacity. Why 75% capacity? 25% reserve capacity is necessary in case of excessive water use from time to time.
Example: 3 people (75 gallons per person per day) in a home avg. 225 gallons of water used per day with 15GPG will need a 32,000 grain system set up for 24,000 grain capacity.
- If you need to convert hardness from ppm to Grains per gallon (GPG) divide the total water hardness by 17.1.
Example: 200ppm of total hardness / 17.1 = 11.69 GPG
- If iron is present in your water supply please add 5 grains of hardness for every 1 ppm of iron and determine your size water softener from there.
