Frequently Asked Questions About Burst Pipe

How do I turn off my water in an emergency?

Locate your main shutoff valve — typically under the kitchen sink, in the basement, crawlspace, or near the water meter at the street. Turn the gate valve clockwise (righty-tighty) or use the lever valve to the perpendicular position to stop flow.

Will my homeowner's insurance cover a burst pipe?

Most standard homeowner's policies cover sudden and accidental burst pipes but may exclude gradual leaks or freeze damage if the home was unheated. File a claim immediately and document all damage before repairs.

How long does it take to repair a burst pipe?

Simple repairs on accessible pipes take 1–2 hours. Pipes inside walls or under slabs may require 4–8 hours or more depending on access. Emergency same-day service is available from most plumbers.

What causes pipes to burst in winter?

Water expands 9% when it freezes. Pipes in uninsulated exterior walls, crawlspaces, or attics are most vulnerable. Keep your thermostat at 55°F minimum and let faucets drip during extreme cold.
