What is an acceptable water hardness level?

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.

Is TDS the same as water hardness?

TDS and hardness are water quality parameters. The main difference between TDS and hardness is that TDS include inorganic and organic substances that cannot be filtered through a filter paper whereas hardness is due to the presence of magnesium and calcium salts of carbonate, sulfate and chloride.

How do you convert TDS to hardness?

However, for estimation purposes, the water hardness can be roughly calculated by dividing the ppm (parts per million) measurement of the TDS by 10 giving a hardness value with an error of only 2-3 French degrees. TDS measurements can also be derived from relative conductivity measurement.

Can hardness be greater than TDS?

Yes – when the water is very hard, a good percentage of the TDS will be made up of hardness minerals, but a lot of it won’t be. So your TDS value will always be significantly higher than the hardness value. The other thing you can’t do with a TDS meter is use it to figure out how well your softener is working.

How can I check my home water TDS?

To do that, follow the given instructions:

  1. Remove the protective cap.
  2. Turn the TDS meter on.
  3. Immerse the meter into the water up to the maximum immersion level (2 inches).
  4. Gently stir the meter to dislodge any air bubbles.
  5. Wait till the reading stabilizes (approximately, 10 seconds).

How do you calculate ppm of water hardness?

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.
