What Central Texas Hard Water Does to Your Plumbing
October 14, 2026 · 5 min read
Our area's water is loaded with minerals. Here's what that means for your water heater, fixtures, and pipes — and what you can do about it.
If you've lived in Central Texas long, you've seen the white crust on faucets and showerheads. That's limescale from hard water — water carrying dissolved calcium and magnesium picked up from the limestone our region sits on. It's safe to drink, but it's rough on plumbing.
What hard water does
- Water heaters: minerals settle out of the water when heated and form a sediment layer in the tank, reducing efficiency and shortening the unit's life
- Fixtures: scale builds up on aerators, showerheads, and valves, restricting flow
- Appliances: dishwashers and washing machines accumulate scale on heating elements and valves
- Pipes: over many years, scale can narrow the inside of pipes, especially hot water lines
Signs hard water is affecting your home
- White or chalky buildup on faucets and showerheads
- Spots on dishes and glassware straight out of the dishwasher
- Reduced hot water pressure or a rumbling water heater
- Soap that doesn't lather well
What you can do
Flush your water heater regularly to clear sediment before it hardens into a solid layer. Clean faucet aerators and showerheads in vinegar to dissolve scale. If buildup is a constant battle, a water softening or conditioning system treats the whole house at the point of entry — we're happy to talk through whether that makes sense for your home.
