Calculate Water Hardness



Formula

To calculate the Water Hardness (H):

\[ H = \frac{C \times V}{17.1} \]

What is Water Softener Hardness?

Water softener hardness refers to the amount of dissolved calcium and magnesium in the water, which are the minerals that make water "hard." These minerals can cause scale build-up in pipes and appliances, making them less efficient and potentially shortening their lifespan. A water softener removes these minerals, reducing the hardness of the water and preventing these issues. The level of hardness in water is usually measured in grains per gallon (gpg), with anything over 1 gpg generally considered hard water.

Example Calculation

Let's assume the following values:

Using the formula:

\[ H = \frac{200 \times 1000}{17.1} = 11696.49 \text{ gpg} \]

The Water Hardness is 11696.49 grains per gallon (gpg).
