Tampa Water Hardness, Explained

By Gary Corriston

If you live in Tampa Bay and your dishes come out spotty or your skin feels dry after a shower, you're not imagining it. Most water across our area is hard — and that has a real, measurable effect on your home.

What "hard water" actually means

Hard water simply means there's a lot of dissolved minerals in it — mostly calcium and magnesium. These minerals are picked up as water moves through Florida's limestone. They aren't harmful to drink, but they cause a long list of everyday annoyances.

How hard water shows up at home

  • White, chalky spots on glasses, dishes, and faucets
  • Soap and shampoo that won't lather well
  • Dry, itchy skin and dull hair
  • Scale building up inside your water heater and pipes
  • Appliances that wear out sooner than they should

How hard is Tampa's water?

Water hardness is usually measured in grains per gallon (gpg). Anything above 7 gpg is considered hard, and much of Tampa Bay runs well above that. The only way to know your home's exact number is to test it.

The good news: hard water is one of the easiest water problems to fix.

What you can do about it

A water softener removes the hardness minerals before water reaches your taps. That means no more spots, softer skin, easier cleaning, and longer-lasting appliances.

The first step is always a free in-home water test, so you know exactly what you're dealing with before spending a dollar.
