Why McKinney Has Hard Water (And What to Do About It)

Hard Water in McKinney: What to Do About It

If you have lived in McKinney for any length of time, you have seen the white scale buildup on faucets and showerheads. Collin County water is notoriously hard, typically measuring 15 to 25 grains per gallon, well above the national average.

Effects on Your Home

• Plumbing: Mineral deposits gradually narrow pipes, reducing water flow and increasing pressure on joints.
• Appliances: Water heaters, dishwashers, and washing machines lose efficiency and lifespan when scale builds inside them.
• Fixtures and surfaces: Soap scum, spotted glassware, and dull laundry are all symptoms of hard water.

Whole-Home Water Softener Options

The most effective solution is a whole-home water softener installed on your main supply line. There are two primary types:

• Salt-based ion exchange: The gold standard. Removes calcium and magnesium completely. Requires periodic salt refills.
• Salt-free conditioners: These do not remove minerals but change their structure so they do not stick to surfaces. Lower maintenance but less effective at very high hardness levels like McKinney's.

For McKinney's extreme hardness, most plumbers recommend a salt-based system sized for your household water usage. Professional installation ensures proper bypass valves and drain connections.
