San Diego water hardness is a common issue for local homeowners—and one that often goes unnoticed until damage appears. If you’re seeing white scale on faucets, dealing with dry skin, or noticing appliances wearing out faster, hard water is likely the cause.
At Hague Quality Water, we help homeowners understand their water and choose the right treatment through trusted water testing San Diego residents rely on and proven San Diego water softeners.
What Is Water Hardness and Why Does It Matter?
Water hardness measures the amount of dissolved calcium and magnesium in your water.
These minerals aren’t harmful to drink—but they are harmful to plumbing, appliances, and comfort.
Hardness is measured in:
- Grains per gallon (GPG)
- Milligrams per liter (mg/L)
General Hardness Scale
- 0–3 GPG: Soft
- 3–7 GPG: Moderately hard
- 7–10 GPG: Hard
- 10+ GPG: Very hard
Most San Diego homes fall into the hard to very hard range.
