If you’ve noticed your water heater isn’t performing like it used to—or if you’ve heard people mention “hard water” but aren’t sure what that means—you’re not alone. Many Southern California homeowners are surprised to learn just how much their water quality can impact their plumbing systems, especially their water heaters.
What is hard water? Why does it matter? Is that something I should be concerned about? And most importantly, what can you do to protect your water heater and avoid costly repairs?
What Is Hard Water?
Hard water is water that contains a high amount of minerals, mainly calcium and magnesium. While these minerals aren’t harmful to your health, they can be hard on your home’s plumbing and appliances.
Here’s how to tell if you might have hard water:
- White, chalky buildup around faucets and showerheads
- Soap that doesn’t lather well or leaves a film on your skin
- Water spots on clean dishes
- Clothes feel stiff after washing
- Reduced water pressure in your home
Why Hard Water Is a Problem for Your Water Heater
Your water heater works hard every day, especially if you have a large household or use hot water often. When hard water flows through your system, those minerals begin to build up inside the tank or along the heating elements.
Over time, this can lead to:
- Reduced efficiency – Mineral buildup forces your water heater to work harder, using more energy to heat your water.
- Shorter lifespan – Excess buildup can cause overheating or damage inside the tank, reducing the life of your unit.
- Strange noises – Popping or rumbling sounds often mean there’s sediment or scale buildup inside your tank.
If you’re experiencing any of these issues, hard water might be to blame.
How to Protect Your Water Heater from Hard Water Damage
The good news? There are simple, effective ways to protect your water heater and extend its lifespan.
1. Flush Your Water Heater Regularly
Sediment from hard water can settle at the bottom of your tank. Flushing the tank once or twice a year helps remove this buildup and keeps your system running smoothly.
2. Install a Water Softener or Conditioner
Water softeners (not recommended due to environmental impacts) and conditioners (recommended) are designed to reduce or neutralize hard minerals before they reach your water heater. This not only protects the unit but can also improve the overall water quality throughout your home.
3. Schedule a Professional Evaluation
