What does 30000 grain capacity mean?
What Does 30,000 Grain Water Softener Mean? 30,000-grain water softener means that it is theoretically capable of removing that many grains of hardness before it needs to regenerate. The hardness is the number of minerals that the water softener can take in before it needs to refresh and drain itself.
What does grain mean in water?
The hardness of water is measured in grains per gallon (gpg). One grain of hardness is equal to 1/7,000 pound of rock. Your municipal water supply may measure water hardness in milligrams (mg), liters (L) or parts per million (ppm). One gpg is equal to 17.1 mg/L or 17.1 ppm.
How many grains should my water softener be?
Determine the proper water softener based on your hardness and number of people in your house.
| Hardness in Grains Per Gallon | 1 to 2 people* | 5 to 6 people* |
|---|---|---|
| 5-10 GPG | 32,000 Grain | 32,000 Grain |
| 11-20 GPG | 32,000 Grain | 40,000 Grain |
| 21-30 GPG | 32,000 Grain | 64,000 Grain |
| 31-40 GPG | 40,000 Grain | 64,000 Grain |
What does grain capacity mean?
Grains capacity is simply the amount of hardness that can be removed by a water softener before it must regenerated. That’s right – a water softener described as a 32,000 grain softener could also be called a 20,000 grain or 25,000 grain softener.
What is a good number for water hardness?
The membrane manufacturers will often specify what the maximum hardness concentration can be, but industry rule of thumb is that hardness should not exceed 120 to 170 mg/L (7 to 10 grains per gallon).
Is 50 ppm hard water?
Water hardness is usually expressed as the number of parts per million (ppm) of calcium carbonate present in the water (see Table 19)….77 Water Hardness and pH.
| Type of Water | Hardness |
|---|---|
| Soft water | 10-50 ppm |
| Slightly hard water | 50-100 ppm |
| Hard water | 100-200 ppm |
| Very hard water | Over 200 ppm |
How do you determine water grain?
If a test for hard water is measured in parts per million or milligrams per liter you can take the total hardness level and divide it by 17.1 to get hardness in grains per gallon. For example if your water test shows 250 mg/L hardness you actually have 14.62 grains per gallon.
How do I know what grain water softener to use?
Use the following formula to calculate the proper size:
- Multiply the number of people in your family times 70 (gallons of water used per day, national average).
- Multiply the answer by your water hardness in grains per gallon (to convert mg/l or ppm to grains, divide by 17.1).
- This is your “grains per day” number.
Is 14 grains hard water?
7–11: Hard water is packed with minerals at 7–11 gpg, and you likely deal with crusty faucets and pipes and possibly reddish rings on your porcelain from excess iron. 11–15: Considered very hard, water at 11–15 gpg exhibits all the signs of hard water all the time. 15+: Extremely hard water is anything over 15 gpg.
What is an acceptable water hardness level?
Is 25 ppm hard water?
You can convert among water hardness measures. Water with hardness of 25 ppm = 25 mg. of hardness-causing minerals per liter of water.
What is a good pH level for water?
between 6.5 and 8.5
If water is below 7 on the pH scale, it’s “acidic.” If it’s higher than 7, it’s “alkaline.” EPA guidelines state that the pH of tap water should be between 6.5 and 8.5.
