0–3: If your hard water test strip indicates that your water is between 0–3 grains per gallon, your water doesn’t require softening. 3–7: Water between 3–7 gpg is moderately hard, causing spotty dishes and dry skin.
What is the ideal water hardness?
A water softener can resolve this problem. 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).
How do I know what water softener setting to use?
The softener capacity is calculated in three simple steps:
- Convert water hardness from ppm to grains per US gallon. Total Hardness (ppm) = Total Hardness (gpg) Example: 118 ppm TH = 6.9 gpg, …
- Calculate softener capacity in grains. …
- Calculate softener capacity in gallons.
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 acceptable water hardness ppm?
Less than 60 mg/L is considered soft. Between 60 and 120 mg/L is considered medium hard. Between 120 and 180 mg/L is considered hard. More than 180 mg/L is considered very hard.
At what hardness Do you need a water softener?
When Is Water Softener Needed? A water softener is needed when your water hardness is above 300 PPM or over 15+ grains per gallon. This is when you may notice changes in the water in your house or your health.

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 |
Can a water softener be set too high?
If the hardness is set too high, the softener will cost more to operate and waste water, costing you extra money. If your home has new copper plumbing, do not run the water softener for at least the first few weeks you use water at your house.
What should my salt level be in my water softener?
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.
Is the higher the number the softer the water?
If your water hardness testing strip or filtration kit indicated a measurement of 1 gpg (17.1 ppm) or less congratulations, you have soft water. But, if you have any number higher than this, you have hard water problems. The higher the number, the harder your water is, and the problems it causes will be more extensive.
Is 47 ppm hard water?
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.
Is 70 ppm hard water?
The hardness of water is determined by the milligrams of calcium carbonateper litre and is reported it in parts-per-million (ppm). 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.
Is 200 ppm hard water?
Hardness 100 – 200 ppm (calcium carbonate)
Water is in the range of 100 to 200 ppm of hardness is considered moderately ‘hard’ water. Natural waters may range from close to zero hardness to many hundreds of parts per million.
What is considered soft water?
Soft water is water that has less than 1 gpg of hardness. When water falls from the sky, it contains no minerals, it picks up these minerals as it travels through the earth. Areas where chalk, limestone and marble are abundant tend to have the hardest water. Soft water easily forms a lather with soap.
What is a good soft water number?
The general rule of thumb is to drink clean water, with hardness being somewhere in the middle of soft and hard, 60 mg/L to 120 mg/L. Some also advise to not go beyond 170 mg/L, which indicates very high levels of calcium and magnesium.
Is 150 ppm hard water?
Natural waters may range from close to zero hardness to many hundreds of parts per million. In our experience, water over 100 or 150 ppm (approximately 8 – 10 grains/gallon) is hard enough to warrant water softening. When the water hardness exceeds 250 – 300 ppm, a water softener becomes somewhat of a necessity.
Is 400 ppm hard water?
An acceptable range of AOAC hard water hardness for 400 ppm is 360 to 420 ppm. ii. An acceptable range of OECD hard water hardness for 375 ppm is 338-394 ppm.
How soft should house water be?
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.
How soft should well water be?
Soft: Less than 1.0 gpg or 0-60 mg/L. Slightly hard: 1.0-3.5 gpg or 17.1-60 ml/L. Moderately hard: 3.5-7.0 gpg or 61-120 mg/L. Hard: 7.0-10.5 gpg or 121-180 mg/L.
Does water hardness affect pH?
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.
What is my water hardness number?
Water Hardness Table of Classifications
| grains per gallon (gpg) | milligrams per liter (mg/L) parts per million (ppm) | Water Quality Association Classification |
|---|---|---|
| <, 1.0 | <, 17.1 | soft |
| 1 to 3.5 | 17.1 to 60 | slightly hard |
| 3.5 to 7.0 | 60 – 120 | moderately hard |
| 7.0 to 10.5 | 120 – 180 | hard |
How do I know if my water softener is too high?
Take a bucket-full of water and add a reasonable amount of soap. Stir the mixture and see if the bubbles produced will be a lot or less than normal. Few bubbles are a sign that the water is hard to lather- A clear sign that your water softener is faulty or not working.
How do I adjust the hardness on my water softener?
Press the UP or DOWN buttons to set your water hardness number. NOTE: If your water supply contains iron, compensate for it by adding to the water hardness number. For example, assume your water is 20 gpg hard and contains 2 ppm iron. Add 5 to the hardness number for each 1 ppm or iron.
Can you put too much salt in softener?
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.
How long does a 40 lb bag of water softener salt last?
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.
Should my water softener have water in the salt tank?
The brine tank is the part of your water softener that holds the salt. Your water level should always be slightly lower than your salt level in your water softener brine tank. This is because the water needs to touch the salt so that it can absorb it and create the correct concentration of brine.
What do the numbers on my water softener mean?
Once you test your water and get your number, see where your water falls using the guide below: 0–3: If your hard water test strip indicates that your water is between 0–3 gpg, your water doesn’t require softening. 3–7: Water between 3–7 gpg is moderately hard, causing spotty dishes and dry skin.
What size water softener do I need?
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.
Is 80 ppm hard water?
Hardness is Reported in PPM [parts per million] or GPG [grains per gallon]. The perfect hardness for a water ionizer is about 80 – 100 parts per million or 6-7 grains per gallon of hardness. Even though 75 to 100 ppm of hardness is considered hard, it’s not going to interfere with ionization at those levels.
Can you drink 0 ppm water?
There is absolutely no reason to drink low TDS/ppm or deionized water. If you are concerned about water quality, put the money toward the purchase of an effective drinking water filter that removes harmful contaminants from your water.
Is hard water OK to drink?
Is Hard Water Bad for You? You may be wondering, “Can hard water make you sick?” Hard water isn’t dangerous, and while it does have excess minerals that might make the taste unpleasant, it’s generally safe to drink.
Can drinking hard water cause kidney stones?
Kidney stones have many causes and are not only due to water quality. However, studies have shown a significant risk increase when consuming hard water. Research also says that staying hydrated is one of the best ways to reduce your risk.
What is the average ppm for tap water?
The typical sample of tap water in the U.S. contains approximately 350 parts per million (ppm) of TDS, which does not on its own indicate a health concern.
Can hard water turn into soft water?
Using a water softener is the easiest way to convert hard water into soft water. Here are some of the benefits of using a water softener: Hard water leaves white spots behind. But, using the water treated by water softener can rinse the residue of soap keeping the dishes clean and no white spots are left on them.
Is soft water OK to drink?
Can I Drink Softened Water? While most softened water is perfectly safe to drink, the amount of sodium in the treated water will depend on the hardness of the original water. If the water hardness is below 400 ppm calcium before you soften it, then you can drink it with little concern.
Is spring water hard or soft?
Since spring water emanates from underground water sources, it dissolves naturally occurring minerals and electrolytes like magnesium and calcium from the rock. As a result, spring water is generally considered hard.
