What is the Ideal Water Hardness Level?

Water hardness is an important aspect of water quality that affects various aspects of our daily lives, from household chores to personal health. Understanding the ideal water hardness level can help you maintain the right balance in your water supply, providing numerous benefits for your home and family.

While there is no “perfect” water hardness level, soft water is generally considered to have a GPG (grains per gallon) of 0 to 3, or a PPM of 0 – 51. Anything that is higher than this is considered hard water, and you might need to use a water softener to help you.

If you want to remove dissolved minerals, such as dissolved calcium or dissolved magnesium, from your drinking water, you need to understand the water hardness scale and find the right water softener to help you.

Understanding Water Hardness and Dissolved Minerals

Water hardness refers to the concentration of dissolved minerals, primarily calcium and magnesium, in the water. These minerals are naturally present in the earth’s crust and dissolve into groundwater over time. Hard water has a high mineral content, while soft water has a low mineral content. Water hardness is typically measured in grains per gallon (gpg) or parts per million (ppm) of calcium carbonate (CaCO3).

Effects of Water Hardness

Water hardness can have both positive and negative effects on your household and personal health. Excess calcium, magnesium, and other dissolved minerals may exert the following effects:

Positive Effects

  • Mineral Intake: Hard water can contribute to your daily intake of essential minerals, such as calcium and magnesium, which are vital for bone health and overall well-being.
  • Taste: Many people find that hard water has a better taste due to the presence of minerals.

Negative Effects

  • Scale Buildup: The minerals in hard water can accumulate on surfaces and form scale deposits, which can cause damage to appliances, plumbing fixtures, and heating systems.
  • Reduced Soap and Detergent Effectiveness: Hard water can react with soap and detergents, forming a residue that is difficult to rinse off. This can lead to dingy laundry, spots on dishes, and reduced cleaning efficiency.
  • Skin and Hair Issues: Hard water can leave a residue on your skin and hair, potentially causing dryness, irritation, and dullness.

It is critical to understand the benefits and drawbacks to make sure you have the right water hardness level in your home.

Determining the Ideal Water Hardness Level: Measure Water Hardness

There is no universally agreed-upon ideal water hardness level, as different households and individuals may have different preferences and needs. You need to think about your overall water quality, alongside your hardness level, when you consider the health and efficiency of your plumbing appliances as well.

At the same time, a general guideline can be followed to determine a suitable water hardness level for most households:

Water Hardness LevelGrains per Gallon (gpg)Parts per Million (ppm)
Soft Water0-30-51
Moderately Hard Water3-751-120
Hard Water7-10120-171
Very Hard Water10+171+
Water hardness levels

Most experts recommend aiming for a water hardness level between 3-7 gpg (51-120 ppm) for a balance of mineral intake and minimal negative effects. It is important to note that excessively soft water can be corrosive, potentially damaging your plumbing system and leaching metals, such as lead and copper, into your water supply.

For these reasons, you need to keep a close eye on your water hardness level and think about the health of your overall water supply.

Testing Your Water Hardness Level

So, what do you need to do if you want to figure out your overall water hardness level? There are a few key points to consider:

To determine the hardness level of your water, you can:

  • Check Your Local Water Report: Many municipalities provide water quality reports that include information on water hardness. You can usually find these reports online or request a copy from your local water provider.
  • Use a Test Kit: You can purchase a water hardness test kit online or at a local home improvement store. These kits typically include test strips or liquid reagents that can measure the mineral content in your water.
  • Hire a Professional: For a more comprehensive water analysis, consider hiring a professional water testing service. They can provide detailed information on water hardness and other water quality parameters.

Remember that you can also reach out to an expert at DROP if you need help getting figuring out your overall water supply’s hardness level.

Adjusting Your Water Hardness Level

If your water hardness level is outside the recommended range, you can take steps to improve it and maintain the ideal balance:

Water Softeners

Water softeners are a popular and effective solution for reducing water hardness. They work by using a process called ion exchange, which replaces the calcium and magnesium ions in the water with sodium or potassium ions.

This reduces the mineral content and prevents scale buildup, soap scum, and other issues associated with hard water. Depending on your household, you will need the right size.

On your water softener, you can adjust the water hardness levels by changing your settings.

Water Filters

In some cases, water filters can help improve water hardness levels by removing specific minerals or impurities.

Reverse osmosis (RO) systems, for example, can effectively reduce water hardness by removing a significant portion of the dissolved minerals. However, these systems can also remove beneficial minerals and may produce water that is too soft, so it is essential to find the right balance based on your specific needs.

Water Conditioners

Water conditioners, also known as descalers or anti-scale systems, are another option for managing water hardness. These devices do not remove the minerals from the water but instead alter their crystalline structure, preventing them from forming scale deposits.

Water conditioners can be an attractive option for those who wish to maintain some mineral content in their water while minimizing the negative effects of water hardness.

Maintaining the Ideal Water Hardness Level: Soft Water

Once you have achieved the desired water hardness level, it is important to monitor and maintain it to ensure optimal water quality:

  • Regular Testing: Periodically test your water hardness level to ensure it remains within the recommended range. This can help you identify any changes in water quality and address them promptly.
  • Water Softener and Filter Maintenance: Regularly maintain and service your water treatment equipment, such as water softeners and filters, to ensure they continue to operate effectively. This may include replacing filter cartridges, cleaning the brine tank, and adding salt to salt-based water softeners.
  • Professional Consultation: If you are unsure about the best approach to managing your water hardness level or need assistance with water treatment equipment, consult a professional. They can provide expert guidance and recommendations tailored to your specific needs.

Keep in mind that you never have to go through this process on your own. You may want to reach out to an expert who can help you not only measure your water hardness level but also find the right water softener to help you.
