Plumbing in Louisville: what locals should know
Water quality
Louisville has moderately hard water which can reduce water heater lifespan over time. Consider a water softener or tankless unit with a descaling system to protect your investment.
Freeze risk
While Louisville doesn't see extreme cold regularly, freezing temps do occur. Insulate outdoor faucets and any pipes in unheated spaces. Disconnect garden hoses before the first frost.
Material recommendation
For Louisville's hard water, PEX piping is ideal — it doesn't corrode or develop pinhole leaks like copper can in mineral-rich water. It's also the most cost-effective option for whole-house repiping.
Local tip
Older homes in Louisville (pre-1970) often have galvanized or cast iron drain pipes that deteriorate over decades. A camera inspection ($150-300) can reveal hidden corrosion before it causes a major leak or backup.
