Why pipes freeze and burst
Water expands about 9% when it freezes. In a sealed pipe, that expansion creates enormous pressure that splits copper, cracks PVC and bursts fittings. The damage often is not discovered until the pipe thaws and water pours out.
Most vulnerable pipes
Exterior walls, unheated basements and crawl spaces, garages, attics and outdoor hose bibs. Kitchen sinks on exterior walls are a frequent casualty in PA homes.
Prevention checklist
Disconnect garden hoses and shut off exterior spigots. Insulate exposed pipes with foam sleeves. Seal drafts near pipes. During deep freezes, open cabinet doors under sinks and let faucets drip. Keep the thermostat at 55°F or higher even when away.
How to thaw a frozen pipe safely
Open the faucet so melting water can escape. Apply gentle heat with a hair dryer, heating pad or warm towels, starting at the faucet end. Never use an open flame. If you cannot locate or reach the frozen section, call a plumber.
If a pipe bursts
Shut off the main valve immediately, then call our burst pipe repair team at (888) 809-6756 — we respond 24/7 across Pennsylvania. Our emergency plumbers will make a permanent repair and check the rest of the system for hidden cracks.
Don't forget the sump pump
Discharge lines freeze too, causing sump pumps to burn out or basements to flood during winter thaws. Make sure yours discharges freely.
