Problems

Fix the symptom—then the cause

Spots, scale, and softener failures. Troubleshooting paths that point back to hardness and systems—not near-me installers.

The Hardwater101 promise

Test first Know gpg before you buy
Root cause Cleaning alone rarely ends hard-water spots
Pro limits Cutting mains → licensed plumber

We don’t sell installers. We give diagnostic paths so you test hardness and check the softener before you buy parts you may not need—or call a plumber for a main cut.
