Understanding your water hardness is crucial for maintaining your home’s plumbing, appliances, and even your personal care routine. Hard water, rich in minerals like calcium and magnesium, can lead to scale buildup in pipes, reduced efficiency in water heaters, and dry skin and hair.

- Moderately Hard: 61-120 ppm (3.6-7.0 gpg)
- Hard: 121-180 ppm (7.1-10.5 gpg)
- Very Hard: 180+ ppm (10.5+ gpg)
Note: ppm stands for parts per million, and gpg stands for grains per gallon.

What to Do If You Have Hard Water
If your tests reveal hard water, consider these options:
- Install a water softener: This is the most comprehensive solution for whole-house treatment.
