Hard water is quietly destroying your appliances

White, chalky crust on the showerhead. Cloudy spots on glasses that just came out of the dishwasher. A water heater that gave out sooner than it should have. In Northern Virginia, those usually trace back to the same thing: hard water.

Our water runs moderately hard to hard, and the dissolved calcium and magnesium leave scale inside every appliance that heats water. Over the years, that scale shortens the life of your water heater, dishwasher and washing machine. The good news is that it's a well-understood problem with a well-understood fix.

What our technicians check first: showerheads and aerators

Weak shower flow is one of the most common complaints we hear, and homeowners often blame it on old pipes. Very often it's scale clogging the showerhead or the faucet aerator instead. Scale buildup restricts flow and can mimic a much more serious plumbing problem.

We've seen homeowners pay for pipe repairs when scale on a showerhead was the real issue. That's why the showerheads and aerators are among the first things our technicians look at, before anyone talks about pipe work. If those are clear and the flow is still weak, then it's time to look further, and our leak and water pipe repair team takes it from there.

How scale shortens a water heater's life

Scale is what forms when calcium and magnesium precipitate out of heated water. Your water heater heats water all day, so it takes the biggest hit.

Inside the tank, scale settles on the bottom and acts as insulation between the burner or element and the water. The heater has to run longer to do the same job. It works harder, and it wears out sooner.

A tank water heater can last a decade or more. Hard water can take years off that. If you've had to replace one earlier than you expected, scale is a likely suspect.

Dishwashers, washing machines and the rest of the house

Dishwashers and washing machines heat water too, so scale shortens their lives as well. You'll also see it in everyday ways:

• White, chalky deposits on showerheads and faucets
• Cloudy spots on glassware after a dishwasher cycle
• Soap and detergent that won't lather well

That last one is easy to miss. The minerals interfere with soap's ability to lather and clean, so you end up using noticeably more soap and detergent to get the same result. The cloudy film on your glasses is a sign of the same thing.

Hardness can drift a little through the year, but it never goes away on its own.

Is Northern Virginia's water hard?

Yes. It's moderately hard across most of the region, and hardness varies somewhat depending on which utility and water source serves your street. The only way to know what's coming out of your tap is to test it.

Our water heating and filtration team can test your water and show you exactly what you're dealing with. If you're curious about what else is in local water, our guide to what's in Northern Virginia's tap water covers the bigger picture.

When a water softener makes sense

A whole-house water softener is the standard fix. It protects your water heater, dishwasher, washing machine and fixtures from scale, so they last longer and your showerheads stay clear.

Timing matters, but not the way people think. If you have a newer water heater, a softener protects it from the start. If you're planning a water heater replacement, adding a softener at the same time protects the new unit from day one. And even if your current heater is 8 to 10 years old, a softener still protects the replacement and every other appliance in the house.

If you're already seeing scale on fixtures, appliances wearing out early, or soap that won't lather, it's a good time to act.

What drives the scope of a softener installation is your home's size and how much water your household uses. We look at both, and we give a written, upfront quote before any work begins.
