Hard Water

You may be wondering what is hard water, and how does it affect you and your home?

Hard water is water that has high mineral content (in contrast with “soft water”). When water combines with Carbon Dioxide it forms a very weak “carbonic” acid, then as this water moves through soil and rock, the acidic nature dissolves some of the minerals and holds them in the water. The most common minerals, calcium and magnesium, are beneficial to our health, but they also cause scale build-up.

Hard water problems are very common in most of Texas, but some are more extreme than others. In your city or even your neighborhood, the water hardness will vary because of the different sources for city water or depth of a well.

The degree of hardness increases with more measured dissolved calcium and magnesium.  How this is measured can be in multiple formats (see the chart below).  For example on Canyon Lake’s Water Quality Report the total hardness is measured in parts per million (ppm) which show amount detected to be 333 ppm.  If you look on the chart below, anything over 181 ppm is considered VERY Hard. That same report also states the acceptable hardness range allowed is 187–333 ppm which means that entire range is above the VERY Hard level.

As there are other minerals (iron, manganese) and the level of the pH in water, also contributes to (compensated) hardness, in local tests, we find that our local Municipal’s test between 25-35 grains per gallon (gpg) or 428 – 599 ppm.  This is higher than they report, because they are only reporting on calcium and magnesium – your plumbing feels compensated hardness!

While most contaminants are reported in ppm, Hardness is usually reported in gpg (grains per gallon).  Sometimes water companies like to get a little tricky in their reporting. Below is a chart to help you do the math.

Classification Hardness in mg-CaCO3/L Hardness in mmol/L Hardness in dGH/°dH Hardness in gpg Hardness in ppm
Classification:Soft Hardness in mg-CaCO3/L:0–60 Hardness in mmol/L:0–0.60 Hardness in dGH/°dH:0–3.37 Hardness in gpg:0–3.50 Hardness in ppm:0–60
Classification:Moderately hard Hardness in mg-CaCO3/L:61–120 Hardness in mmol/L:0.61–1.20 Hardness in dGH/°dH:3.38–6.74 Hardness in gpg:3.56–7.01 Hardness in ppm:61–120
Classification:Hard Hardness in mg-CaCO3/L:121–180 Hardness in mmol/L:1.21–1.80 Hardness in dGH/°dH:6.75–10.11 Hardness in gpg:7.06–10.51 Hardness in ppm:121–180
Classification:Very hard Hardness in mg-CaCO3/L:≥ 181 Hardness in mmol/L:≥ 1.81 Hardness in dGH/°dH:≥ 10.12 Hardness in gpg:≥ 10.57 Hardness in ppm:≥ 181
A Water Softener Is The Solution For Hard Water - Central Texas Water Softeners

A Water Softener Is The Solution For Hard Water

Find the right Water Softener for your needs

Hard water can wreak havoc on your plumbing, appliances, and daily routines. The solution lies in a water softener. By using advanced ion exchange technology, water softeners effectively remove the minerals causing hardness, such as calcium and magnesium ions. The result is noticeably softer water that not only enhances the performance of your plumbing and appliances but also provides a range of benefits.

With a water softener, you can bid farewell to limescale buildup, clogged pipes, and soap scum residue. Say hello to cleaner dishes, brighter laundry, and softer skin and hair. Your appliances will enjoy a longer lifespan and improved efficiency. Additionally, a water softener helps save money on energy bills by enhancing the effectiveness of water heating systems.
