Hard water is a slow problem, not an emergency, but it quietly shortens the life of expensive equipment.
Why it happens in Salt Lake City
Mineral-rich sources
Wells and mountain sources carry calcium and magnesium.
Winter heater load
Cold incoming water makes heaters run longer, accelerating scale.
Fixture wear
Scale wears cartridges and valve seats.
Appliance buildup
Dishwashers and washers suffer from hard water deposits.
Secondary irrigation water
Some Wasatch Front homes use untreated secondary irrigation water, which can carry sediment and minerals that clog sprinkler components.
Irrigation and outdoor fixtures
Long irrigation seasons leave heavy deposits on sprinkler heads, hose bibs and backflow devices.
Signs to watch for
- White crust on faucets and showerheads
- Rumbling or popping water heater
- Tankless error codes or reduced flow
- Spotty dishes and stiff laundry
- Low pressure at fixtures from clogged aerators
Emergency, or can it wait?
Call right away if…
