What hard water means
Hard water contains elevated dissolved minerals, primarily calcium and magnesium. It is generally not a health concern, but those minerals can remain behind as water is heated or evaporates.
Scale on fixtures and inside piping
White residue around faucets and showerheads is the visible version of buildup that can also occur in aerators, valves, cartridges, and piping. Over time, restriction can reduce flow and make components harder to service.
Water heaters and boilers work harder
Scale can settle in tank-style water heaters and coat heat-transfer surfaces. Tankless units and high-efficiency equipment have narrow internal passages that may require manufacturer-specified flushing or water treatment.
Navien and other equipment should be maintained according to the exact model instructions and local water conditions.
Appliances, soap, and cleaning
Hard water can leave spots on glassware, reduce soap lather, stiffen laundry, and shorten the life of components in dishwashers, washing machines, humidifiers, and coffee equipment.
Confirm the water condition before treating it
A basic water test establishes hardness and can identify other concerns that change the appropriate treatment. Private wells may need broader laboratory testing than municipal supplies.
Treatment and maintenance options
- Clean removable aerators and showerheads as appropriate.
- Maintain water heaters and tankless units on the proper schedule.
- Use point-of-use filtration for a specific taste or sediment concern.
- Consider a correctly sized whole-home softener when hardness warrants it.
- Have treatment equipment installed and set up to protect plumbing and drainage.
