When this applies
When to address it
If you're constantly cleaning scale or replacing fixtures and appliances early, treating the water at the source solves the root cause.
How it works
Why it builds up
As hard water is heated or evaporates, dissolved minerals precipitate out as scale — inside pipes, on heating elements, and on every surface water touches.
What to watch out for
Scale in the water heater
Scale insulates the heating element or burner, forcing it to work harder, raising energy bills, and shortening the heater's life.
