An acceptable level range for water hardness is going to be 100- 300 PPM depending on what city you live in and what the water treatment plant has decided on.
A water hardness of 0 to 3 gpg is soft water, 3 to 7 gpg is moderately hard and 7 to 11 gpg is considered hard. Anything more than 11 is considered very hard.
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).
The higher the number, the softer the water. – Quora. Hard water usually contains minerals in the water that when that water is used to wash dishes or take a bath it leaves behind a residue.
The level of water softener salt in a brine tank should be at least one quarter full, no more than 4-6 inches below the top of the tank, and a few inches above the water level. Before adding any new salt to a tank, loosen any encrusted salt stuck to the sides of the tank.
|Hardness in Grains Per Gallon||1 to 2 people*||7 to 8 people*|
|31-40 GPG||40,000 Grain||96,000 Grain|
|41-50 GPG||64,000 Grain||110,000 Grain|
|51-75 GPG||64,000 Grain||110,000 Grain|
|76-100 GPG||80,000 Grain||110,000 Grain|
There is no such thing as too soft water. Hard water contains metal cations and nonmetal anions. In a softener, the cations are replaced by sodium ions, and the anions are replaced by chloride ions. Once all the hardness ions have been replaced, the process stops.
|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|
Measures of water hardness
General guidelines for classification of waters are: 0 to 60 mg/L (milligrams per liter) as calcium carbonate is classified as soft; 61 to 120 mg/L as moderately hard; 121 to 180 mg/L as hard; and more than 180 mg/L as very hard.
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.
To determine the appropriate water softener size for your home, multiply the number of people in your home by the gallons of water they use each day (80 gallons per person is the average). Multiply that number by the grains of hardness in your water to figure out how many grains need to be removed each day.
Soft water provided by a utility does not need additional softening and may cause corrosion issues for your home. Make sure the softener is set to the hardness of your water supply. If the hardness is set too high, the softener will cost more to operate and waste water, costing you extra money.
In general, water with less than 60 ppm can be considered soft, water with 60-120 ppm moderately hard, and water with greater than 120 ppm hard.
Soft water replaces those magnesium and calcium ions with sodium ions. The result is soft water, loaded with salt. The salt is what makes the water feel slimy. After you buy a water softener, you might feel slimy and slippery after you take a shower, like you haven’t gotten all the soap off of you.
Don’t Add Too Much Salt
Adding too much salt to your water quality softener can cause salt “bridging,” or a buildup and solidification of regenerant. This buildup can prevent your system from regenerating properly.
Your salt consumption will depend on the level of water hardness (minerals in your water) and the amount of water your household consumes. The average family of four with hard water (7-10 grains per gallon hardness level) will use about one 40-lb bag of salt each month.
Your water softener brine tank should never be full of water. Even if your water softener brine tank is half full of water, then you have a problem.
Softened water is considered safe to drink in the majority of cases. … In softened water, the sodium level increases. Sodium is not the same as salt (sodium chloride). The Drinking Water Inspectorate (DWI) says that water with a sodium content of up to 200ppm is safe to drink.
Hardness does not pose a health risk and is not regulated by state or federal agencies. … The following classifications are used to measure hardness in water: soft 0 – 17.1 parts per million (ppm); slightly hard 17.1 – 60 ppm; moderately hard 60 – 120 ppm; hard 120 – 180 ppm; and very hard 180 or more ppm.
Hard water (high mineral content) is usually high in pH. Soft water (low mineral) is usually low in pH. The mineral in hard water will act as a buffer which will reduce the amount of acid in the water. The resulting water will be more alkaline and higher in pH.
You can convert among water hardness measures. Water with hardness of 25 ppm = 25 mg. of hardness-causing minerals per liter of water. Degrees of Water Hardness.
FACT #3: Though hard water does have a higher calcium level than soft water, there is not enough evidence to prove hard water can cause kidney stones. In fact, most hard water does not contain high enough levels of minerals to be a danger to our health.
An average softener should remove 4000 grains of hardness for every One pound of salt used.
For your water, 170 PPM is the same as saying the water has 10 grains per gallon of hardness. This is moderately hard but not extremely hard water. You may expect to see some white scale building up on fixtures, but many homeowners live with 10 grain per gallon water with no problems.
Most notably, soft water lacks the heavy minerals that can damage hair and make it less resilient to other changes (like stress or diet). Because soft water can penetrate the hair follicle more fully, it generally helps hair look shinier, softer, and less damaged.
California water is considered hard to very hard. The average water hardness for California residents is 100-300 PPM. The state’s most populous city and the second-most populous city in the US, Los Angeles, has a water hardness average of 127 PPM and San Francisco has a hard water level of 47 PPM.
Water softening salts are essential to treat water and maintain the high performance of water softeners. When the water softener runs out of salt, it can cause long term damage and harm your water fixtures. It can even result in tank overflowing.
Water Softener Crystals are recommended for households that have lower than average water consumption or for those who use a two-part water softening system. … Water Softener Pellets can help reduce bridging, work better for moderate to high volume water users, and all-in-one tank system users.
