Plumbing in Allentown: what locals should know

Freeze risk
In Allentown, pipe freezing is a moderate-to-high risk during the coldest months. Make sure you know where your main water shutoff valve is — quick action when a pipe bursts can save thousands in damage.

Local tip
Older homes in Allentown (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.
