Plumbing in Columbia: what locals should know
Water quality
Columbia 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 Columbia 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.

In Columbia, copper piping can develop pinhole leaks over time due to hard water. PEX is increasingly the preferred alternative — it's corrosion-resistant, flexible, and more affordable.
Local tip
Older homes in Columbia (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.
